What is Mcrit?
What is Mcrit?
Mcrit is the aircraft’s Mach speed at which the airflow over a wing becomes sonic.
What navigational instruments does the Boeing 737-800 have?
What navigational instruments does the Boeing 737-800 have?
IRS / GPS / VOR / DME
What is N1, N2, EGT and EPR?
What is N1, N2, EGT and EPR?
N1= Low pressure compressor spool or fan rotation speed. Usually expressed as a % of Max N1.
N2= High pressure compressor rotation speed.
EGT= Exhaust gas temperature, indicates the temperature at the first stage of the turbine, which is the most critical temperature in the engine.
EPR= Engine pressure ratio of the inlet to the jet pipe, displayed on the EPR gauge to use as a parameter for setting engine thrust
Why do we use Jeppesen charts/plates?
Why do we use Jeppesen charts/plates?
Jeppesen charts and plates are simplified and uniform.
What is the difference between angle of attack and angle of incidence?
What is the difference between angle of attack and angle of incidence?
Angle of attack is the angle between the chord of the aerofoil and the relative airflow.
Angle of incidence is the angle between the chord and the aircrafts longitudinal datum.
What is an NDB?
What is an NDB?
Non Directional Beacon, a medium range radio navigation aid that sends out a signal in all directions for an aircraft to home to.
How do you prevent an aircraft reaching Mcrit?
How do you prevent an aircraft reaching Mcrit?
Decreasing speed, by reducing engine power or pitching up.
If in a go-around, which take-off stages will still apply?
If in a go-around, which take-off stages will still apply?
None. The go around procedure is distinct from the take off procedure. You will still have an acceleration altitude, but you will not have a screen height, V1, Vr, V2, flap retraction altitude, etc.
What is a Mach trimmer?
What is a Mach trimmer?
A Mach trimmer is a system that artificially corrects for Mach tuck.
What is windshear?
What is windshear?
Windshear is a change of wind speed and/or direction from place to place, including updraughts and down draughts.
It is ussualy characterized by a strong change over a short distance. Windshear can effect the flight path and airspeed and can be hazardous.
