Question

When must the bleed air be off during takeoff? a) Just after touchdown b) During the takeoff roll c) While in the final approach d) At the top of climb

Answer 1

Bleed air, compressed air produced by jet engines used in various aircraft systems, should be turned off during takeoff roll to maximize engine power.

Step-by-step explanation:

The term 'bleed air' in aviation refers to compressed air produced by jet engines, which is 'bled' off and used for various aircraft systems. One such system is the pressurization and climate control within the plane's cabin. However, during specific stages of flight operations, primarily during takeoff roll, the bleed air is turned off to maximize the engine power available for accelerating the aircraft and climbing to altitude. Therefore, the bleed air must be off during the takeoff roll.
