How does an aerofoil work?
An aerofoil is a body shaped to produce an aerodynamic reaction (lift) perpendicular to its direction of motion, for a small resistance (drag) force in that plane. It achieves this by accelerating the flow passing over it, and decelerating the flow passing under it. This change in velocity causes a change in pressure, which in turn generates lift.
What are the disadvantages of a swept wing?
What are the disadvantages of a swept wing?
Swept wings have:
-
Poor lift qualities
-
Higher stall speeds
-
Speed instability at low speeds
-
A wing-tip stalling tendency
What would you do in the event of an engine failure below V1, and what would your initial actions be?
What would you do in the event of an engine failure below V1, and what would your initial actions be?
Assuming I'm performing single pilot operations:
-
power idle,
-
max brakes (and reversers if available),
-maintain directional control using rudder input,
-
After coming to a full stop set parking break.
-
Inform ATC 'Stopping'.
-
Initiate the appropriate process to diagnose the problem (ECAM, NITS DODAR, checklists....).
-
When performing multi pilot operations the actions performed by me will depend with my current role: PF, PM and/or CM1 CM2.
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.
Approach category speeds are defined by which formula?
Approach category speeds are defined by which formula?
This speed is defined to be equal to the greater of stall speed (Vso) multiplied by 1.3, or stall speed (Vs1g) multiplied by 1.23.
The landing configuration that is to be taken into consideration can be defined by either the operator or by the aeroplane manufacturer but is most commonly assigned by the manufacturer.
Can you explain what a coastal breeze is?
Can you explain what a coastal breeze is?
A coastal breeze is a wind from the sea that develops over land near coasts.
It is formed by increasing temperature differences between the land and water; these create a pressure minimum over the land due to its relative warmth, and forces higher pressure, cooler air from the sea to move inland.
Generally, air temperature gets cooler relative to nearby locations as one moves closer to a large body of water.
What are the advantages of fuel injection vs a carburetor?
What are the advantages of fuel injection vs a carburetor?
Fuel injection provides:
-
Fuel free from vaporization ice
-
Better economy through metered delivery
-
More responsive and efficient engine
-
Less maintenance
If you climb to FL300 at a constant IAS of 250kts, what would happen to the TAS?
If you climb to FL300 at a constant IAS of 250kts, what would happen to the TAS?
TAS will increase.
What is the advantage of a variable pitch propeller? Why not have a fixed propeller?
What is the advantage of a variable pitch propeller? Why not have a fixed propeller?
A variable pitch propeller provides an optimum angle of attack for the propeller blades for a longer range which reduces fuel usage. Fixed pitch propellers are easier to produce and maintain, but reach maximum efficient at only one specific airspeed.
What are TORA, TODA, ASDA clearways, stopways, and screen heights?
What are TORA, TODA, ASDA clearways, stopways, and screen heights?
TORA= Takeoff Run Available, the length of runway declared available and suitable for the ground run of an aeroplane taking off.
TODA= Takeoff Distance Available, the length of the take off run available (TORA) plus the length of the clearway, if available.
ASDA= Accelerated Stop Distance Available, the length of the takeoff run plus the length of the stopway, if available.
A clearway is an area beyond the paved runway, free of obstructions and under the control of the airport authorities. The length of the clearway may be included in the length of the takeoff distance available (Take Off Distance Available (TODA)). For example, if a paved runway is 2000 m long and there are 400 m of clearway beyond the end of the runway, the takeoff distance available is 2400 m long.
The stopway is an area beyond the runway which can be used for deceleration in the event of a rejected takeoff.
Screen height: TODR is the distance from the brake release point to the point where the aircraft gains a height of 35 ft above the ground. This 35 ft is what we call the screen height. While 35 ft is the screen height for class A airplanes, it is 50 ft for class B airplanes.
On a wet runway, the screen height is reduced to 15 ft.
