Non-standard Missed Approach Altitudes

G'day,

Was wondering if there was anything to stop you nominating a higher missed approach altitude in uncontrolled airspace.

With controlled airspace it would be a matter of requesting a non-standard altitude.

In uncontrolled airspace, can you nominate a higher altitude if you inform the ATS unit responsible for passing traffic info to others and also the nattended traffic for area of intended approachy7

Example, a NDB approach has a company specified circling minima of 1200ft, the published MAPP altitude is 2300ft. that 1100ft can go pretty quick with an initial GA climb in excess 2500fpm.

Is there anything specifically preventing us nominating 4000ft as a non-standard altitude, to allow an easier time of the turning MAPP procedure? Assuming we inform an ATS unit and the unattended traffic frequency...

Why would you climb at 2500 ft/mn + to gain 1100ft on a MAP ? If flying a top end aircraft, you need to "trigger" the logic by "passing by" the GA ( like on ATH or similar,) but then...it is either all automatic, and they do reduce nicely, or the automation is crap, and then the magic hands just have to throttle back...
I do not know NZ precisely, nor the airport you are referring to; but some people may be holding somewhere around you etc.. If the initial GA around altitude is set at this value, there is usually a good reason for it..

my view of course..

No need for smartarse comments. The OP asks a perfectly reasonable question.
Answer
If you are outside controlled airspace, yes of course you can nominate a higher missed approach altitude.
In fact, if you are number one in the approach sequence, with another aircraft following, it makes sense to select a higher altitude, so that in the event you both miss out the following aircraft won't run up your clacker.
All this assumes that you are communicating your intentions clearly, and the other aircraft acknowledges.

In context, "nominate" has several synonyms, including "select" "choose " "decide on".

I get that part. I was more curious as to nominated before whom? The Nobel Committee? The Board of Trustees?

Uncontrolled airspace = do what you want! Airmanship is all that matters, If you want to climb higher for whatever reason then do so. However, be aware that the missed approach altitude has been certified to be safe and all
other traffic will expect you to climb to that level.

Regarding high rates of climb... why bother? You could just creep it up at a 1000fpm. There's no reason to shoot on up there.

Amadis. I have no idea what you're talking about. Nominate is the perfect term to use in this context. Is English a second language?

Fourth, actually (no kidding). The only time I've seen "nominate" in any aviation context was something like "I hereby nominate Lucky McPiston as Pilot of the Year". Certainly never heard or seen it in a missed approach situation.

The OP asked a reasonable question, couched in explicit terms. He got a few valid answers. But Amadeus, you waded in with a non sequitur and have since compounded it by persisting. Unless you are a total retard, or have never operated in uncontrolled airspace, you know perfectly well from reading the first post that the pilot would be transmitting his intentions on the local frequency, ie 'nominating' the altitude he is climbing to on his missed approach. He is not obligated to send this message in triplicate to ICAO in Montreal or Geneva or wherever they are convening this week. Once you have found the definition of 'nominate' go to 'uncontrolled'. Stuff me.....
Normally I would not play the man, only the subject. But I have to say you would make a great check captain with Anal Airlines.

Amadis, don't be such a pleb, suggest you follow this link:

Let me google that for you

Definition, to name, to state.

To the OP:

In uncontrolled, you can do what you like. We have a few approaches on our network with low level offs or early turns, which can have you chasing your tail, or missing something in the rush to level off such as flap retraction, much better to take your time by climbing straight ahead to a higher level if available.

Obviously if there's an aircraft at 3000', you will only be able to climb to 2000' for separation.

Indeed, it's been nearly a decade since I've flown in uncontrolled airspace. No plans to do it again any time soon.

I never said the original question was unreasonable. Well, at least to the extent that coming to an anonymous forum asking real-world operational questions is "reasonable"...

Ladies and gentlemen, like RTN11 we should really try to help this poster improve both his/her formative (4th language!!) English and computing skills.

Amadis - 'nominate' is from the latin root nomen which translates into English as 'name', so sqwark was effectively saying he/she was 'naming' the g/a altitude and was correctly using the word. It appears you are being a little confused by things like TV catch-phrases like Oscar 'nominations' and so on - but I guess Latin is not unfamiliar to you with your Spanish connections.

As RTN says, if you come across a word in any language that confuses you, you can look up the definition on line - and avoid driving Don Quixote mad..
