Why does the speed tape on the PFD reads 45kt when the aircraft is stationary?

Why does the speed tape on the PFD reads 45kt when the aircraft is stationary?

The speed is too low for an indication.

Altimeter errors:

Instrument error Pressure error Time-lag error Barometric error

What is alternate air? And what is its relation with the air filter?

If you where picking up 10.000 litres of fuel in Newfoundland (cold weather), and 10.000 litres of fuel in Lima, Peru (hot weather), where would you have picked up the most fuel?

If you where picking up 10.000 litres of fuel in Newfoundland (cold weather), and 10.000 litres of fuel in Lima, Peru (hot weather), where would you have picked up the most fuel?

In Newfoundland. With cold weather density increases, therefore you would pick up a higher mass in Newfoundland.

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 is radiation fog?

What is radiation fog?

Radiation fog forms on cloudless nights with only very light winds and high relative humidity when the cold ground cools the air above it to its dew point causing condensation (fog).

Usually occurs inland in valleys and low lying areas (as these areas tend to have more moisture) and usually occurs in a high pressure system.

Why would someone fly a Rhumb Line track?

Why would someone fly a Rhumb Line track?

  • If no IRS/INS/GPS was available, it’s easier to fly a constant heading (but you will need to apply variation).

  • If flying over short distances (as done during your training) the error introduced by flying a rhumb line is insi

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

Because usually the heated air bypasses the air filter, therefore it is possible for dust to enter the engine and so exposing the engine to unnecessary engine wear.

What are the effects on the human body in case of depressurisation?

What are the effects on the human body in case of depressurisation?

Hypoxia, a lack of oxygen to tissues of the body due to low partial pressure at altitude.

Symptoms are: blue lips, apparent personality change, impaired judgement, muscular impairment, short term memory loss, sensory loss, hyperventilation, unconsciousness.

Other possible effects:

  • Baurotrauma

  • Lung damage
