Why Planes Lower their Flaps Before Takeoff and What Happens if they Don't

Описание: Lowering flaps during takeoff is a crucial aspect of aircraft operation, and it's essential to understand why it's done and what happens if it's not.

Why Planes Lower Their Flaps During Takeoff:

Increased Lift: Flaps help increase the wing's lift coefficient, allowing the aircraft to take off at a slower speed and shorter distance.

Improved Control: Flaps also enhance the aircraft's controllability during takeoff, making it easier to handle and more stable.

What Happens If Planes Don't Lower Their Flaps:

Increased Takeoff Distance: Without flaps, the aircraft requires a longer runway to take off, which can be problematic on shorter runways.

Reduced Control: Failure to lower flaps can lead to reduced controllability, making the aircraft more difficult to handle during takeoff.

Increased Risk of Accidents: Neglecting to lower flaps can increase the risk of accidents, particularly during takeoff.

Examples of Incidents Involving Problems with Airplane Flaps:

Air India Express Flight 812 (2010): The aircraft crashed while landing at Mangalore International Airport, killing 158 people. Investigation revealed that the pilots failed to extend the flaps to the recommended setting, leading to a loss of control.

Turkish Airlines Flight 1951 (2009): The aircraft crashed into a field while approaching Amsterdam's Schiphol Airport, killing nine people. Investigation showed that the pilots failed to extend the flaps to the correct setting, resulting in a loss of lift.

Delta Air Lines Flight 2412 (2012): The aircraft made an emergency landing after the pilots discovered a problem with the flaps. Investigation revealed that a faulty sensor had caused the flaps to malfunction.

These incidents highlight the importance of proper flap extension during takeoff and landing. Failure to follow standard operating procedures can have catastrophic consequences.
