Pressure and Warm/Cold Atmosphere
The altitude indicated on board an aircraft flying in an atmosphere
where all the atmosphere layers below the aircraft are cold is?:
Why is the answer to the above question
"lower than the real altitude"
This one has me bamboozled?
If someone could explain in v simple terms I'd really appreciate it. I do not understand why it doesnt follow the "High to Low -Look out Below' adage
Many thanks
