What altitude will you fly after a missed visual approach?
 
Hi gentlemans:What altitude will you fly after a missed visual approach?Just maintain pattern altitude again or ?.........:confused:

Lightning6 31st Aug 2009 05:11

Just fly back into the circuit pattern, unless advised otherwise by ATC.

Clandestino 31st Aug 2009 06:36

What altitude & procedure will I fly after a missed visual approach?
 
The one arranged with ATC, preferably before commencing the approach. Usually missed app instructions are issued with app clearance. If not, I ask for them.

OzExpat 31st Aug 2009 07:48

Might also be a good idea to pre-brief for this possibility, taking account of obstacles in the vicinity, airspace limitations, etc. Perhaps even more important if operating single pilot, but is a good way to avoid last minute surprises for the PNF.

captjns 31st Aug 2009 09:11

If flying a published visual approach procedure then climb to the altitude indicated on the approach chart.

If flying a self positioning visual approach, ask the controller issuing the visual approach clearance as to both altitude and heading requirements should a missed approach have to be flown.

You can confirm the missed approach procedures, as issued by the approach controller, with the tower when initial contact is made. They may have changes to the missed approach procedures to assure separation from VFR traffic near the airport.

bfisk 31st Aug 2009 20:20

An altitude sufficient to not hit anything. You're visual...

(Yes, I know that is a ****-smartass-fancypants answer, but it's true...)

seilfly 31st Aug 2009 22:49

But you are still IFR although flyging a visual approach, so wouldn't you need to fly an IFR altitude until cleared for another visual approach? -Or cancel IFR to enter the visual pattern?

mad_jock 31st Aug 2009 23:07

I would fly the published missed approach procedure for the instrument approach which we were previously informed we were doing.

For example on contact at MAN you would be informed say "vectors for the ILS 23R" if say the gods have shined on manchester and it isn't raining for once and we request and get cleared for a visual. The missed approach off said visual would be the missed approach for the ILS 23R.

Its a bit like when you do a circling approach your missed approach is the approach that you decended on to cloud break to start the circle. Although to be honest knowbody has ever given me a sensible method of safely doing this.

Bruce Waddington 1st Sep 2009 01:23

Kuobin,

The FAA AIM states that, "e. A visual approach is not an IAP and therefore has no missed approach segment. If a go around is necessary for any reason, aircraft operating at controlled airports will be issued an appropriate advisory/clearance/instruction by the tower. At uncontrolled airports, aircraft are expected to remain clear of clouds and complete a landing as soon as possible. If a landing cannot be accomplished, the aircraft is expected to remain clear of clouds and contact ATC as soon as possible for further clearance. Separation from other IFR aircraft will be maintained under these circumstances."

The Canadian AIM states virtually the same thing. No altitude is specified other than to follow ATC instructions at a controlled airport and to remain clear of cloud at an uncontrolled one.

As mentioned above some published missed approaches do have missed approach procedures to follow, but the are nonetheless not an IAP.

best regards,

Bruce Waddington

OzExpat 1st Sep 2009 09:48

All this advise doesn't really satisfy the consideration of the altitude at which you have to go around from a visual approach. Forget the reason for the need to do so, the fact is that you have to contend with the reality of the situation - most especially at aerodromes that are uncontrolled (i.e. where you actually have to think for yourselves and earn your money as pilot in command).

To me, it really doesn't matter whether the aerodrome is controlled or not. I will still ALWAYS brief a missed approach on the basis of my previous post. Start thinking for yourself!

If ATC is there, fine, start your go-around, tell them - though they'll obviously have seen it. If they then issue an alternative clearance, you can evaluate that against your own briefing so that you KNOW whether or not you're being given a "bum steer". The passengers are YOUR responsibility all the way to the terminal.

potteroomore 2nd Sep 2009 03:18

Ahh....how easy we forget the basics we learnt during our PPL/CPL days!!!

Many years ago in the back waters of SEAsia, I was humbled and shaken by a near airmiss after a missed approach after a visual approach. Years of flying into Syd where the local procedures called for a missed approach following the charted instrument missed approach........so by a force of habit, I carried out the RWY 25 ILS missed approach in KCH ( WBGG ) after being cleared for a visual approach onto that runway. We had sighted the runway but stuffed up the approach after being high and fast. It was a clear day with visibility of 10km or more but cloud base of about 3000 feet. The ILS missed approach called for a climb towards the VKG VOR climbing to 4000 ft. I was on tower frequency and unbeknownst to me, the approach controller had cleared another aircracft to overhead the VOR at 4000 ft and we nearly had a big fireball.........we were saved when my sharp f/o casually mentioned that we ought to join the visual traffic circuit; I said " what, who told you that? " He casually mentioned the name of one of the local training check captain's name and suddenly I had goose bumps; I didn't know why but I just yanked the aircraft into an immediate left turn as we almost disappeared into the stratus layer at about 3500 feet, followed by a real quick descent to circuit altitude as the tower come everly slowly asking our intention! It was a very quiet and squeaky request for another visual circuit when we were advised by tower that the approach ( there was no radar in KCH in the early 90s; no TCAS then, too ) control had cleared the other aircraft for a full ILS with an altitude restriction of 2500 ft until we have landed. Tower had expected us to maintained circuit altitude 1500 ft when we conducted the visual missed approach. It had happened so fast and I must say the tower controller wasn't on the ball too! We finally did another visual approach after the aircraft was sent around to the VOR for another full ILS approach.

What triggered the goose bumps and the sharp left turn which saved the day? About a year earlier had a route check and was debriefed by a particular line check captain that I ought to set the circuit altitude on the MCP altitude selector as the missed approach altitude and expect to join the aerodrome visual circuit should I had to carry out a go around during a visual approach. Well, this chap was a young chinaman who was made instructor/checker after less than a year as a captain on the B734 after coming down from the B744; well I guess we Oz expats did not take too kindly to young upstarts, suffice to say I didn't take him too seriously and just errr ed& hummed my way during the debriefing!! However I was truly lucky that subconsciously, that debrief leapt into me at the right time. And my f/o was similarly briefed on this by that same instrucor during his line training and he managed to sheepishly remind ( albeit casually ) this highly experienced foreign captain to join the visual circuit! Talk about divine intervention or providence!! I bought my f/o a full dinner with the whole works that night! And months later I ran into that instructor ( well, he had transitioned onto the A330 ) and I thanked him profusely.......he had forgotten about that debrief but mentioned that he was amazed at how we pilots have forgotten the basics that we learnt our PPL/CPL training after we obtained out ATPLs!

slamer. 3rd Sep 2009 07:59

Short answer is.. Depends what specific state rules require. Ref Jepp or equivalent publication.

Busserday 3rd Sep 2009 16:14

Accepting a Visual Approach is in fact canceling the IFR flight plan and if you choose to go flying past the last cleared point, probably the button of the active, don't expect separation from any IFR traffic. Stay clear of cloud and respect the VFR rules, other than that, you are on your own. Otherwise don't accept a "Visual".

mad_jock 3rd Sep 2009 16:42

Busserday not in Europe you ain't.

Its quiet an eye opener this and a point learned about reading that bit in the JEPs which is usually only ever seen when you do the updates.

seilfly 3rd Sep 2009 16:52

How can a visual approach cancel an IFR flight plan when it is defined this way...?

FAA.gov:

VISUAL APPROACH- An approach conducted on an instrument flight rules (IFR) flight plan which authorizes the pilot to proceed visually and clear of clouds to the airport. (the rest is cut away to shorten the quote)

VISUAL APPROACH [ICAO]- An approach by an IFR flight when either part or all of an instrument approach procedure is not completed and the approach is executed in visual reference to terrain.

Busserday 3rd Sep 2009 17:38

Mad Jock, reference please, I don't seem to be able to find a Jep reference to Visual Approachs for Europe.

mad_jock 3rd Sep 2009 21:38

It might not include it if its US only plates. I don't have a clue if it is or isn't

In an Eur version there is one book which has all the ICAO regulations in it which is as quoted by seilfly and then there is a section with all the differences which each individual country has filed.

And to add the second comment I made was to myself to read that section to see what the differences are.

totempole 6th Sep 2009 23:32

me thinks potteroo is on to something correct. the local AIP or terminal charts will indicate missed approach procedures if charted like SFO or SYD. or if the tower clears you for a visual approach, the controller will give you a missed approach instruction in case you missed or if you carry out a go around you contact the tower pronto for instructions. in the absence of all the above, for god sake you are responsible for staying visual, avoid clouds, traffic and obstacles and join the prevailing traffic pattern. this more so in smaller airports where the tower is a one man show where the controller controls ground traffic, dishing out airways clearances etc. just because you are an atp flying big jets going to big airports with radar control and never joining a visual traffic pattern doesn't mean you forget your responsibility of visually eyeballing yourself into a visual traffic pattern after going around.

PantLoad 7th Sep 2009 06:22

Sop Sop Sop Sop Sop
 
My company's SOP for such a situation was to climb to the missed approach altitude for the instrument approach that serves that runway.
If there is no such instrument approach, climb to normal pattern altitude
or MSA or MVA or as assigned by ATC.

Fly safe,

How about the Circle to Land MHA(H) - safe and also tells you which sector is not approved for circling?

bookworm 8th Sep 2009 07:22


flying under EU OPS published missed approach
Reference please? Or is that a company-specific thing for an EU-OPS operator?

I flew a missed approach after a visual approach in France a couple of days ago. I got directions (turn right downwind) but no altitude instruction, though in the mayhem that was Le Touquet on Sunday I imagine the controller had lost track of who was IFR and who was VFR.

9.G 8th Sep 2009 08:48

bookworm, nice nickname btw. Well, it's the definition as such. Under Eu OPS visual approach is still part of IFR clearance thus published missed applies unless of course ATC instructs you otherwise. Under FAR it was quoted before visual isn't part of IFR any more. That's the whole difference.

Homo proponit, sed Deus disponit.:ok:

bookworm 9th Sep 2009 07:29

Neither assertion is correct, 9.G. A visual approach is an IFR approach under both FAA and EU OPS rules, and indeed under ICAO rules (PANS-ATM 6.5.3). But since an IAP may not even have been included in the clearance, there may be no "published missed approach" to fly in any jurisdiction. There may even be no IAP for the runway in question. If you can find something in EU OPS to the contrary, then cite it.

OzExpat 9th Sep 2009 11:45

Well, I guess all will be well if you have to go missed approach in EU-land or FAA-land. That's all clear as mud to me. Anyway, if you're anywhere else in this whole wide, wonderful world, you probably better hope that your company has procedures that comply with the local AIP and legislative requirements.

If not, you just might end up spoiling your whole day! :eek:

9.G 11th Sep 2009 12:04

FAA rules:

The FAA AIM states that, "e. A visual approach is not an IAP and therefore has no missed approach segment. If a go around is necessary for any reason, aircraft operating at controlled airports will be issued an appropriate advisory/clearance/instruction by the tower. At uncontrolled airports, aircraft are expected to remain clear of clouds and complete a landing as soon as possible. If a landing cannot be accomplished, the aircraft is expected to remain clear of clouds and contact ATC as soon as possible for further clearance. Separation from other IFR aircraft will be maintained under these circumstances."
Needless to comment methinks.

EU OPS rules:

"Visual approach". An approach when either part or all of an instrument approach procedure is not completed and the approach is executed with visual reference to the terrain.
this definition found in ALL weather OPS section applicable to IFR rules obviously. Therefore under EU OPS visual approach is part if IFR IAP clearance and doesn't covert the flight rules to VFR which would imply flying the circuit altitude. As we're all aware of once the IAP has been commenced it must be finished either in a successful landing or a execution of a missed approach procedure.

All this shouldn't preclude you from doing what's regarded by you as to rightful course of actions.

My eyebrows rose at your comment about Kuching, it is not a backwater, I spent about 14 years flying from there and enjoyed every minute of it.

EpsilonVaz 11th Sep 2009 13:28

Flew a visual approach into a UK airfield yesterday, in the briefing to the Captain, I said "as it's a visual approach, if we need to go around we will climb to the circuit altitude and join downwind". His response "err.... well, let's follow the missed approach procedure for the ILS (which was out of service)." Amid some confusion and debate, I agreed.

9.G 11th Sep 2009 14:01


But since an IAP may not even have been included in the clearance, there may be no "published missed approach" to fly in any jurisdiction. There may even be no IAP for the runway in question.
Bookworm, can you file a IFR flight plan to a destination lacking IAP? No commercial public flight, conducted with performance A aircraft, can be operated under VFR unless explicitly authorized by flight operations manager.
Regarding the approach clearance it's a absolute MUST to specify which approach procedure one is cleared for. Whatever IAP is declared to be in use as per ATIS must be followed unless cleared otherwise. Consequently MA for this particular procedure shall be followed. I totally agree the topic could be explained in a unambiguous way but it's not. Just my 2 cents.

Cheers:ok:

DFC 11th Sep 2009 17:00

A visual approach is a procedure all of it's own. There is no defined obstacle clearance provided and the pilot is responsible for deciding what track and level to fly at to avoid obstacles. The flight is still IFR unless the pilot has cancelled the IFR flight plan.

The US, ICAO and European rules agree on this point.

If you have to execute a missed approach from a visual approach then you fly the missed approach appropriate to that visual approach - as agreed with ATC.

Unless you want a surprise you should ask in advance what ATC want in the event of a missed approach.

If you have discontinued one approach procedure in favour of another then one can not rely on the missed approach being the same. -

The first words of the Visual approach definition - It is a procedure.

A Circling procedure is something that is done after completing an IAP in order to line up with the landing runway. It has a defined containment area and one can not leave the IAP until within this area otherwise obstacle clearance may be compromised.

Unless specified otherwise, the missed approach for a circling is the IAP missed approach - initial turn towards the aerodrome overhead and follow the MAP.

--------

9.G,

Performance A simply relates to the aircraft performance and it's ability to avoid obstacles. The criteria apply in both VMC and IMC, VFR and IFR.

Anyone can file an IFR flight to an aerodrome with no IAP. The flight has to be visual at the IFR minimum safe level in order to descend for landing since it has no procedure for getting lower. This might make operations impractical but not impossible. Some countries require IFR to be cancelled before descending below the minimum level and others do not.

Bruce Waddington 11th Sep 2009 17:11

9.G,

I found the same comments for a visual approach under EU rules, but no other.

So, my question is this.

If a visual approach is " An approach when either part or all of an instrument approach procedure is not completed and the approach is executed with visual reference to the terrain." would that not include the missed approach segment of the IAP ?

Comments ?

best regards,

Bruce Waddington

9.G 12th Sep 2009 17:25

DFC, what is climb gradient requirement for performance class A aircraft departing VFR please? The answer is simply NONE avoid it by visual means that's it. All performance criteria are applicable to Instrument procedures for one very valid reason coz you don't see them thus one must meet performance. The title in the 4444 doc is Instrument procedure design not Visual procedure design. To underline it you have the choice of avoiding obstacles by visual means in case of EO. The whole idea of constructing the procedures is about making a blind IFR flight safe, nothing else. Obviously that's the reason why NO public commercial flight with performance class A aircraft can be operated under VFR unless authorized so. It's simply much safer to fly IFR.

if no IAP is available at the time of arrival IFR flight can be dispatched und IFR/VFR with the DFO consent and IFR portion must be canceled once safe landing can be assured by visual means. Good luck filing IFR flight plan to an airdrome with no published IFR procedures.

Cheers.:ok:

9.G 12th Sep 2009 18:34


If a visual approach is " An approach when either part or all of an instrument approach procedure is not completed and the approach is executed with visual reference to the terrain." would that not include the missed approach segment of the IAP ?
Let's have a practical look at it, shall we? Under EU OPS min req. VIS for a visual 800 m not more than that. Can you fly a traffic pattern with this VIS? I have my doubts. The purpose of the visual approach is to be placed into a position preferably on final to complete IFR procedure by visual means. nothing else. It's different under FAA, don't ask me why. Under no cuircumstances do the flight rules change you still fly IFR. Aerodrome traffic pattern is a standard procedure for VFR flights not IFR. Under IFR you fly circle to land not a a traffic pattern consequently in case of a go around you don't just join a VFR circuit pattern but fly MA for IAP in use. Why should it be any different for a visual approach? Once again in MHO the key to understanding here is the applicable rules namely Instrument flight rules. In any case I stand to be corrected of course.
Cheers.:ok:

DFC 12th Sep 2009 23:30

9.G,

A performance A aircraft from V1 on must be able to become airborne safely, clear all obstacles by the required margin and fly to a place where a safe landing can be made.

The only thing that being VMC gains the Performance A operator is the ability to determine track accurately and thus reduce the size of the area in which obstacles have to be cleared by the net minimum.


Under EU OPS min req. VIS for a visual 800 m not more than that. Can you fly a traffic pattern with this VIS? I have my doubts
The 800m is an arbitary figure. To make a visual approach then you have to be visual. You do not have to be VMC. It is not unusual to have a lovely clear sky with not a cloud in sight for 500 miles and the only thing stopping your visual approach is a bit of shallow fog at the aerodrome giving a reported visibility of 500m eventhough you can clearly see the landing threshold. Far safer to do the ILS in that case.

john_tullamarine 13th Sep 2009 09:25

A performance A aircraft from V1 on must be able to become airborne safely, clear all obstacles by the required margin and fly to a place where a safe landing can be made.

Presuming all goes well. Theory versus the real world, I'm afraid. Reads better if you replace "must" by "probably should on most occasions".

The only thing that being VMC gains the Performance A operator is the ability to determine track accurately and thus reduce the size of the area in which obstacles have to be cleared by the net minimum.

Depends on the rules applicable. eg in Oz, above a specified MTOW, the takeoff has to be predicated on the presumption of IMC. In any case, with the usual jet pitch attitude, I suggest that it is folly to attempt to eyeball a critical departure.

DFC 13th Sep 2009 17:49


In any case, with the usual jet pitch attitude, I suggest that it is folly to attempt to eyeball a critical departure.
I was never suggesting that a performance A aircraft would be required to visually avoid obstacles in the take-off funnel.

What I was trying to explain is that for example in the case of a departure with a track change of more than 15 degrees, the maximum width of the take-off funnel is 1200m if the pilot can acurately maintain the requried track and 1800m if they can't. In the absence of suitable navigation aids, a limitation of VMC can give the pilot the ability to maintain the required track visually so that the funnel is smaller.

Imagin a departure along a tight valley with a 30 degree turn 1nm after the runway end. No navigation aids. If IMC is permitted then the funnel expands until it is 1800m wide - taking in quite a bit of the hills each side of the valley. If the procedure is limited to VMC then the pilot can (a) determine the 1 mile point if there is a good landmark and accurately track the valley centerline thus reducing the final size of the funnel and the height of the obstacles that are in it.

Hope that explains my point better.

Agree with the statistical situation but ensuring that the net requirments are met makes it very unlikely that the gross performance will be less than the net - assuming all factors are as planned of course!!

bookworm 13th Sep 2009 18:45


Bookworm, can you file a IFR flight plan to a destination lacking IAP?
Yes.

But I think you're missing the point of the sentences you quoted from me. Even if there is an IAP, it may not have been assigned before the clearance for a visual approach is given, and a visual approach may be made to a runway without an IAP.


The FAA AIM states that... Needless to comment methinks.
The comment should be obvious -- that a visual approach under FAA rules is conducted under IFR, not VFR.

mad_jock 13th Sep 2009 18:59

There are a few departures out there which are VMC limited dependant on the aircraft.

The one that springs to mind is Vargar in the Faroes. If you don't have the single engine climb performance your only option is to fly it visually.

The 146's are quite happy to climb straight out into IMC but my TP has to fly down the valley remaining in contact with the ground and a bloody great rock at the end of the valley until I clear the end and make a turn to the south.

I disagree that a visual approach is an approach all of its own. You are still as such doing the initial cleared approach . Your just visually missing bits out and getting to exactly the same missed approach point. In a radar environment the missed approach maybe very different to the published purely for the reason they can and it helps the other traffic. In a procedural environment its the only thing the controller can pin his hat on to ensure separation. If you do decided to deviate from said missed approach you really are on your own for terrain avoidance and quite possibly endangering other aircraft because the procedural controller won't have a clue where you are in relation to their picture of traffic.

Calvin Hops 13th Sep 2009 22:25

potteroo..........are you referring to a certain MAS TRE known as dynamite? Well, I learnt a lot from this unassuming gentleman especially during the period when we had chaos in the Malaysian skies when a fire destroyed the radar and atc equipment. Flying during that period reminded me of earlier times in PNG and Bourganville!
