How would you explain to your neighbour what the difference is between a precision and a non-precision approach?
How would you explain to your neighbour what the difference is between a precision and a non-precision approach?
A precision approach uses both lateral (from left to right) and vertical guidance. A non-precision approach only uses lateral guidance.
What uses the most battery power, to transmit or to receive?
What uses the most battery power, to transmit or to receive?
Transmitting uses more power.

What are the advantages of operating a one aircraft type fleet, why don’t we use an A320 / B737 mixed fleet?

The FMA indicates what system is controlling the aircraft and what mode is operational.
Explain the Fohn wind.
Explain the Fohn wind.
A Fohn wind is a warm dry wind that blows down the lee side of a mountain.
Initially, the air temperature cools dry-adiabatically (3°C/1000 ft), until its dew point temperature is reached. Condensation occurs as the air is further forced up the mountain range, resulting in the air cooling saturated-adiabatically (generally considered in the mid-latitudes to be 1.8°C/1000 ft). Clouds and precipitation form. When the air mass reaches the top of the mountain range it has lost a significant amount of its water content and so has a much lower dew point temperature.
As the air then begins to descend down the lee slope of the mountain the compressed air is initially heated saturated-adiabatically, and in effect the direct reverse to the cooling effect on the windward side occurs. As the air continues leeward and downward from the mountain range, the air, now no longer saturated, is heated dry-adiabatically.
The resultant wind is dry and warm giving clear conditions at airfields on the lee side of the mountain range.
The Foehn Effect also may be associated with mountain wave activity.
How does an IRS work?
How does an IRS work?
An IRS is an Inertial Reference System which consists of accelerometers, gyroscopes (laser) and a position computer.
The computer calculates the aircrafts position by direction and velocity sensed by the accelerometers from the initial latitude and longitude input.
An IRS enables the aircraft to fly great circle tracks and to navigate accurately across vast expanses where no ground based navigation aids are available.

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 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
