IR take off minima

[Captain Douglas]

Anyone know what the take off minima(RVR and cloud base) is for a pilot with an IR. Let's say a non public transport flight on a single crew aircraft? eg PA23

If anyone knows the official reference where one could find such info. please let me know as I have been trying to find it all day long and I got fed up looking.

Capt D,

I believe the info you are looking is :

For non public transport single engine (irrespective of pilot qualification or licence) is 600ft cloud base for take off and 1800m RVR. I think the minimum cloud ceiling for public transport single engine is 1000ft.

Any other offers ???

[inverted flatspin]

In the US N reg Part 91 you can legally take off on a private flight 0-0.

Not that anyone ever does the prevailing attitude is thanks for allowing us but that would be a bad idea. The airlines or infact anyone carrying people for hire have minimums set out in the revlevant FAR chapter.

Try CAP507 which supports what onemore has said.

This reminds us that JAR OPS 1 does not permit commercial operations in IMC for a single engined aircraft.

RVR,

Of course u r correcet RVR with the multi engine criteria, but that is only one of them ! The rest of the regs regarding multi engine are;

(1) For a multi engine aircraft with no engine out climb capability the minima is 600ft cloud and 1800m RVR.. .(2) For a multi engine aircraft with a climbout capability of less than 150ft per minute one engine out) the minima is 600ft cloud and 1500ft RVR.. .(3) For a multi engine aircraft exceeding 150ft/min climb (one engine out) the minima are 300ft cloud and 800m RVR.

The above applies to aircraft under 5700kg.

Onemorehold,

Where may one find this information that you have disclosed?

[easondown]

Capt D,

Its just info that I carry around in my head !!, no but seriously I dug it out from the UK AIP RAC 4-3-2 (14 mar 96) subsection 3.2 and 3.3

Now do you have any difficult questions ??

If you haven't got easy access to the UK AIP and ANO etc, get a copy of the UK AIM - very handy little book that fits in your flight bag. Only costs £14.95.

According to the note at the bottom of AIP AD 1.1 11, it would seem you can land at any aerodrome outside controlled airspace, without regard to any minima! This does not answer your question but, going back a few pages, AD 1.1 seems to give some answers. There is a handy table in AD 1.1 4.1.2 which gives the take-off RVR's for "performance class A" aircraft.

AD 1.1 4.4 gives the single pilot RVR of 800m for approaches - this can be reduced (to the "normal" minima) if you have an ILS-coupled autopilot.

I am fairly sure that if you have the ILS-coupled autopilot in your "Performance Class A" light twin and you are single crew - it is possible to depart with RVR as low as 150m (subject to a suitable take-off alternate being available).

Please put me right if I'm wrong on that last point - interpretation of these rules can be a pain!!

Cheers,

ETR

Quite frankly it scares me that there isn`t one straightup answer to this question, and that everybody keeps referring to different chapters of different regulations.. .Sorry guys, but it seems that the FAA has done at better job at this than any of the European authorities. <img src="rolleyes.gif" border="0">

Try the air traffic Control section of a Jeppesen. .airway manual. It has all the info you need!!

re For non public transport single engine (irrespective of pilot qualification or licence) is 600ft cloud base for take off and 1800m RVR. I think the minimum cloud ceiling for public transport single engine is 1000ft.

I find this farcical if true. Assuming an airfield in class G airspace, I can take off WITHOUT my IR in 1500m viz and clear of cloud, but if I suddenly produce my IR, then this INCREASES to 1800m.?. .Surely not?

[bluskis]

Without an IR a PPL is restricted to a flight vis. of 3km, (without passengers) so could not take off in less.. .With an IMC rating minimum vis. for takeoff is 1800m. I don't think cloud base is specified for t/o, just the requirement to get down safely and legally, which also requires 1800m vis.and appropriate cloud base for the procedure.

I would be interested to know what a CPL holder has as take off limits with and without an IR.

[invalid entry]

I have an ATPL so I could take off in 1500m.

[englishal]

As someone pointed out the T/O minima for an N Reg private flight with IR is 0-0. However it would not be smart to take off in minimums less than is needed for landing at the same airport again in case of trouble etc....

[Freak On A Leash]

Well stated, englishal.This is what common sense dictates. :)

As to the CPL without an IR... well, you`re committed to VFR only so 3000m applies <img src="wink.gif" border="0">

There are no mandatory take-off minima for non-commercial flights in the UK, though there is a recommendation to use the commercial ones.

See AIP AD 1.1.2 paras 1.4 and 4.1

EricTheRed

AIP AD 1.1 11 refers to airports without published IAPs. If the airport has published IAPs, the operating minima (for landing) are mandatory for all flights (ANO Art 40).
