BOAC,

I think I finally got it,
I cannot thank you enough for that great explanation on TAS in relation to a constant airspeed.

Finally I do understand WHY TAS is decreasing with a constant Mach climb.
So to answer the question at 30’000 ft; Mach1: TAS will be lower than at sea level (Due to the temperature).

Let me try again with the TAS climb;
IAS will decrease in a constant TAS climb

So if I got this right AoA would have to increase since my IAS will decrease at a constant Mach climb(in order to produce same amount of lift) .

I did have 2 posts at 2009 about where would be a good place to start my aviation training. And I did remove them

I reckon lessons are over for today!:)

Thanks for the explanation on your posts - solves a puzzle.

Thanks for the post Keith, interesting reading!

BOAC,

May i ask if you have been a CFI, and what you are flying at the moment?

By PM jonzza - on its way.

Keith Williams and BOAC both deserve a pat on the back for answering the question.

I'm afraid numbnuts and john tullamarine both deserve a kick in the arse.
the guy had a serious question and not once did you fckuwits even attempt an answer. you two should really make the effort not to lapse into senility.

chicken tikka masala.
 

I remember somebody telling me chicken tikka masala was the way to remember the relationship twix IAS TAS AND MACH.
of course it's all different in an open cockpit, if you climb at a constant IAS your TAS increases and your Mack flaps about in the relative airflow.

Sorry chaps, late night and an early morning, I'll just get my hat, I already have my Mack!

Agreed.
I had reason to doubt that, so I asked.
Sometimes 'serious questions' are not what they pretend to be.

In october 2008 the guy was located in Sweden and posted that he was going to start pilot training at a school in Norway in january. If that was 'serious', why did he delete those posts?

Yes I deleted my post after your first comment, why would I give away that info when I get a comment like the one you wrote?

"I had reason to doubt that, so I asked"

I think you should go back and read your post because I can not find any question in that post. Just a statement!

If you would have asked I would have happily explain where I started my training and what I am doing today..

Have a great day
