What is advection fog?
What is advection fog?
Advection fog occurs when moist air passes over a cool surface by advection (wind) and is cooled.
It is common as a warm front passes over an area with significant snowpack, but it is most common at sea when tropical air encounters cooler waters, including areas of cold water upwelling, such as along the coast of California.
What wings does the Boeing 737-800 use?
What wings does the Boeing 737-800 use?
Swept back wings
Would you be happy if VMCG is higher than V1?
Would you be happy if VMCG is higher than V1?
No, because if your critical engine fails at V1 you have to continue your takeoff roll, but because you’re under VMCG you are unable to maintain directional control.
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.
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
You need to uplift four tonnes of fuel, how many litres would you ask for if the SG is 0.8?
You need to uplift four tonnes of fuel, how many litres would you ask for if the SG is 0.8?
5000 litres
(4 tonnes / 0.8 = 5000 litters)
Are swept wings effective?
Are swept wings effective?
Swept wings are designed to be the most effective at high speeds. At low speeds, a swept wing produces less lift than its straight counterpart.
What are the lift qualities of a swept wing?
What are the lift qualities of a swept wing?
Poor, because the sweep-back design has the effect of reducing the lift capabilities of the wing.
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.
While climbing with a SEP, in what temperature range can carb icing occur?
While climbing with a SEP, in what temperature range can carb icing occur?
Carb icing can occur with temperatures as high 30°C and humidity as low as 50%, but it is more likely when below 20°C and high humidity, especially during low power settings.
