Missed Approach during circle to land
Hello guys.
Imagine you are approaching to an aerodrome and there is IFR procedure for only one runway. The wind favors the opposite runway and the ceiling is under the minimun required to make a visual circuit.
So, for exemple, you are approaching to runway 10. Once you reach the MDA, you iniciate a circle to land to rwy 28.
After that, when you are on short final rwy 28, for some reason, you have to go around. Which IFR missed approach procedure should you follow?
Thanks.

Assuming you made an instrument approach to RNW10 and circled to land for 28, you have to follow the missed approach procedure for the instrument approach currently in use, which is 10.

You turn into the circling area and follow the missed approach as charted on IFR runway, in this case runway 10. Remember the turn is to be made into the circling area and your configuration post initiation of the missed approach may need be delayed until you are established in the direction of the missed approach (e.g. 737 flap 15 requirement for initial turn into the pattern)

The point being that if you have flown the RWY 10 approach then the next arrival is likely do the same. If you follow the missed approach procedure for RWY 28 then you will be opposite direction traffic - in IMC. Not a good situation!

5. All turns should be made in the same direction and the aeroplane should remain within the circling protected area while climbing either:
i. to the altitude assigned to any published circling missed approach maneuver if applicable;
ii. to the altitude assigned to the missed approach of the initial instrument approach;
iii. to the MSA;
iv. to the minimum holding altitude (MHA) applicable for transition to a holding facility or fix, or continue to climb to an MSA; or
v. as directed by ATS.
When the missed approach procedure is commenced on the ‘downwind’ leg of the circling maneuver, an ‘S’ turn may be undertaken to align the aeroplane on the initial instrument approach missed approach path, provided the aeroplane remains within the protected circling area.
The commander is responsible for ensuring adequate terrain clearance during the above-stipulated maneuvers, particularly during the execution of a missed approach initiated by ATS.
6. Because the circling maneuver may be accomplished in more than one direction, different patterns will be required to establish the aeroplane on the prescribed missed approach course depending on its position at the time visual reference is lost. In particular, all turns are to be in the prescribed direction if this is restricted, e.g. to the west/east (left or right hand) to remain within the protected circling area.
7. If a missed approach procedure is published for a particular runway onto which the aeroplane is conducting a circling approach and the aeroplane has commenced a maneuver to align with the runway, the missed approach for this direction may be accomplished. The ATS unit should be informed of the intention to fl y the published missed approach procedure for that particular runway.

Thanks everyone!!
Avenger, can you tell me where you got this information? Which public document?
Is there any publication beyond the ICAO Doc 8168 and the Circling Approach Discussion Paper??
I ask because some details are still confused. Example: On the short final for rwy 10 at 200ft, I have to go around (imagine the MDA is 600ft). So, first I keep the rwy hdg, climb to 600ft and only after reaching the MDA I iniciate the turn? Or could I made a climbing turn before reaching the MDA?
Thanks, guys!!
I said the ceiling is under the minimum for visual circuit, not for circle to land.

Pedro you seem to be getting confused between circling minima and flying a visual approach? What do you mean by minima for visual circuit and CTL? to commence the circling manoeuvre in the first instance you would need XX VIS/ XX Cloud base. Circle to land is a visual manoeuvre..usually commenced due tailwind limits. You cannot descend below circling minima for the approach unless you have the required visual reference. Both Boeing and Airbus FCTM have information on these manoeuvres and the exact limitations per individual operator are included in their Part A procedures.

I think you'll find that there are some nice people in ATC who will sort matters out....

Kirks gusset, thank you for trying to help, but you do not actually get my point. I said the ceiling is under the minimum for visual circuit, only to avoid responses like: you could go around and make a visual circuit.
In other words, I said that only to emphasize I'd like to know about IFR procedures to perform a missed approach in that situation, not VFR (crosswind leg, downwind leg, etc).

Pedro,
I recommend you to read AIM 5-4-21 item C available here: https://www.faa.gov/air_traffic/publ...ns/ATpubs/AIM/
Some more in your language: Arremetida no procedimento para circular - Técnica e Operações - Fórum Contato Radar
I recommend you to read AIM 5-4-21 item C available here: https://www.faa.gov/air_traffic/publ...ns/ATpubs/AIM/
c. If visual reference is lost while circling-to-land from an instrument approach, the missed approach specified for that particular procedure must be followed (unless an alternate missed approach procedure is specified by ATC). To become established on the prescribed missed approach course, the pilot should make an initial climbing turn toward the landing runway and continue the turn until established on the missed approach course. Inasmuch as the circling maneuver may be accomplished in more than one direction, different patterns will be required to become established on the prescribed missed approach course, depending on the aircraft position at the time visual reference is lost. Adherence to the procedure will help assure that an aircraft will remain laterally within the circling and missed approach obstruction clearance areas. Refer to paragraph h concerning vertical obstruction clearance when starting a missed approach at other than the MAP. (See FIG 5-4-29.)

When I set up this scenario during say, an IR renewal in an FTD, a dismaying proportion of supposedly knowledgeable candidates will charge off in the wrong direction. Throw in a radio call announcing another a/c is established on the localiser, and some "deer in the headlights" moments can ensue while they grapple with diminished situational awareness.

Our AIP has similar text to Sydy.

Bloggs:
I assume when you talk about " weather " you refer to cloud base, not RVR
‘Visual approach’ means 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.
8.1.3.1.6. Visual Approach Operations (AMC9 CAT.OP.MPA.110)
Minimum RVR / visibility for a visual approach is 800 m.
Minimum RVR for a CTL specified by chart or operator, usually not less than 3000m
Circling - MDH and Minimum Visibility vs. Aeroplane Category Table Visual Approach Operations (AMC9 CAT.OP.MPA.110)
Circle to Land
Aeroplane category
MDH / Visibility (ft - m)
Category C
600 - 3000
I fail to see how Visual is "better" than CTL?
Now, if we are saying that the instrument approach is carried out to MDA, say 600' then circling commences with the required RVR, but, on the final approach vis is lost and a missed approach executed I can understand the question and the answers are as prescribed.

"He's not confused." Yes, Bloggs, he is, and so, I think are you. There is no 'Minimum' for a visual circuit which is what Pedro was asking about, not a 'visual approach'. Basic rule for visual circuits is don't hit anything.

Kirks - I assume Ireland conforms to EUOPS and thus the minimum visibility for a CTL is IN FLIGHT VIS (not RVR) and used to be 2400m for Cat C (3600 Cat D?). Also the RVR must not be less than that specified for the instrument approach used - and you need 800m RVR to complete the CTL for the landing. No cloud base specified.
That is your answer as well, Bloggs.
Aerocat - a 'visual approach' is not the same as 'circuit'. Circuits (by definition) go 'round and round' something, but you can land stright in from a visual approach (I hope.........)
