What is the standard temperature lapse rate in the troposphere?
The standard temperature lapse rate in the troposphere is approximately 2°C (3.5°F) per 1000 feet, but the commonly accepted standard is 6.5°C per 1000 meters, which equals roughly 6.5°C per 1000 feet.

What is the primary purpose of a stall warning system in an aircraft?
A stall warning system alerts the pilot when the aircraft is approaching a stall condition, which occurs when the wing exceeds its critical angle of attack and loses lift.
