Ok, so then basically what I make out from what you're saying is that as the dynamic pressure remains constant if we keep a same airspeed as we climb, the anemometer senses the change in density (reduction) and so it is the anemometer that calculates the increased v and displays it in knots on the Airspeed indicator right?
I have one more question which is different to this:
An aeroplane moves from Point A with coordinates 60ºN/030ºW. It then moves the following distances:
1. 3600 Nm South
2. 3600 Nm East
3. 3600 Nm North
4. 3600 Nm West
What is its final position?
I keep getting 60ºN/090ºW but books says 60ºN/060ºW.
Can you please help me with this?
Thanks a lot.
