Air density effects on fuel efficiency/power
Hi. One of the younger lads who i'm learning to fly with (we are in the very early pre GFPT stages) asked me at the aero club the other day in conversation, why it is that a plane burns less fuel and is less efficient (in power). I understand its to do with air density, but does anyone have a simple response. This goes for both piston and turboprop/fan engines.
Thank you in advance
