Why does this smell like a homework question? We don't do homework questions here. We prefer that the student actually does his own research to find his own answers, in the hopes that they might actually LEARN something along the way. The only thing they are going to learn by using Yahoo! Answers is how to cheat

Asking others to do your work for you IS NOT doing research.

Analyse, with the aid of a demand and supply diagram, the effect of an increase in demand for air travel on the wages of pilots.?

Does Peach Airlines (Japan) have the best idea or what?!?

They seat window seat passengers first, no matter what part of theplane. And. There is no first class.

NM is nautical miles - to obtain statute miles, multiply NM by 1.15 -
The speed are generally expressed in knots (like ships) - 1 knot is 1 NM per hour -

In case you work in metric, multiply NM by 1.852 to obtain kilometers -

Finally - range is the maximum distance you can fly with full tanks -
However you should be conservative (and have some fuel reserves) -

Why do black people do this?

Whenever there happens to be a Mulatto woman that is prettier than a full black woman (such as Meagan Good or Alicia Keys...

Just be aware that ATC communications are often very "lax"...
No the ATC controllers... but pilots -
For pilots which very own language is... English (in particular in USA) -
A lot of "slang" is regrettably used on radio communications -

Obviously, on your example, the proper response should be "turning 5º left"
Other problem, if you say "runway 5 left" in USA...
The proper name in ICAO English is "runway zero five left"

But commercial pilots are accustomed to handle radio communications -
Particularly old timers...

I spent 15 years of my airline career with a foreign airline (Argentina) -
I guarantee you, USA radio communications confuse foreign pilots -
There is a lesser degree of discipline with radio in the USA...

I recall some pilots (with USA airlines) using wording such as...
"10-4" (instead of "roger") or "no joy" (to say "does not see the traffic") -

Worse is some controllers forgetting they speak to foreign pilots -
One day I was landing on Rwy 25 at LAX, my first officer was on the radio -
The controller said "Argentina 1234, your traffic is passing the four-o-five" -
I know what the 405 is (freeway) because l lived 30 years in LA -
But the Argentine pilots don't know where the 405 or Hollywood Park is...!

Fact -
USA radio communications are the nightmare of foreign pilots...
Even for those who speak/understand English rather decently -
Ask the opinion of Japanese or Korean pilots...!

When I used to fly to USA, I did the radio in USA airspace myself...!
