What does the manifold pressure gauge measure?
Answer: Absolute pressure in the engine intake manifold
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.
What is the function of the magnetic compass in an aircraft?
Answer: It indicates the aircraft's heading relative to magnetic north using Earth's magnetic field
The magnetic compass uses Earth's magnetic field to indicate the aircraft heading relative to magnetic north.
When an aircraft is described as having a 'tricycle landing gear,' what does this mean?
Answer: Two main gear and one nosewheel
Tricycle landing gear consists of two main gear units under the fuselage and one nosewheel forward of the center of gravity.
What system prevents simultaneous brake application that could cause a main gear blowout during landing?
Answer: Anti-lock braking system (ABS)
Aircraft ABS (anti-skid) systems modulate brake pressure to prevent wheel lockup and tire blowout, especially during heavy braking on landing.
What is the purpose of aircraft flaps during approach and landing?
Answer: To increase lift and drag, allowing a slower approach speed and steeper descent angle
Flaps increase both lift and drag, enabling the aircraft to maintain a slower airspeed and a steeper glide path during approach and landing.
What does 'Vne' (never-exceed speed) represent on the airspeed indicator?
Answer: Maximum speed for structural integrity — marked by the red line
Vne is the never-exceed speed above which structural damage or failure may occur, marked by a red radial line on the airspeed indicator.
