Under what conditions will an aircraft create best lift?
- Hot damp day at 1200 ft.
- Cold dry day at 200 ft.
- Cold wet day at 1200 ft.
Explanation
Lift increases with air density, and density is greatest when the air is cold, dry and at low altitude. A cold dry day at 200 ft gives the highest density of the options, since heat, humidity and altitude all reduce air density and therefore lift.
Aeromechanic asking:
Cold dry is completely opposite in meaning. What is a cold dry day ? Can someone explain .
