Question 1

What does the manifold pressure gauge measure?

Accepted Answer

Absolute pressure in the engine intake manifold

Answer

The manifold pressure gauge measures the absolute pressure of the fuel-air mixture in the intake manifold, indicating engine power output for normally aspirated and turbocharged engines.

Question 2

What is the function of the magnetic compass in an aircraft?

Accepted Answer

It indicates the aircraft's heading relative to magnetic north using Earth's magnetic field

Answer

The magnetic compass uses Earth's magnetic field to indicate the aircraft heading relative to magnetic north.

Question 3

When an aircraft is described as having a 'tricycle landing gear,' what does this mean?

Accepted Answer

Two main gear and one nosewheel

Answer

Tricycle landing gear consists of two main gear units under the fuselage and one nosewheel forward of the center of gravity.

Question 4

What system prevents simultaneous brake application that could cause a main gear blowout during landing?

Accepted Answer

Anti-lock braking system (ABS)

Answer

Aircraft ABS (anti-skid) systems modulate brake pressure to prevent wheel lockup and tire blowout, especially during heavy braking on landing.

Question 5

What is the purpose of aircraft flaps during approach and landing?

Accepted Answer

To increase lift and drag, allowing a slower approach speed and steeper descent angle

Answer

Flaps increase both lift and drag, enabling the aircraft to maintain a slower airspeed and a steeper glide path during approach and landing.
