If you take off on a two engine airplane with no engine failure and are below VMCA, will you have directional control?
If you take off on a two engine airplane with no engine failure and are below VMCA, will you have directional control?
Yes, some directional control as we still have two functioning engines.
Name the different aircraft categories, speeds and on which speed these categories are based.
Name the different aircraft categories, speeds and on which speed these categories are based.
Aircraft categories are based on Vat (in knots):
A <91
B 91-120
C 121-140
D 141-165
E 166 - 210
If the yaw damper fails and the aircraft experiences Dutch roll, how can the pilot stabilize the aircraft?
If the yaw damper fails and the aircraft experiences Dutch roll, how can the pilot stabilize the aircraft?
Apply opposite aileron to the direction of the roll.
Does the N1 compressor produce thrust?
Does the N1 compressor produce thrust?
Yes, with the modern high bypass turbofans the N1 compressor works as a huge propeller, it takes a big mass of air and gives it a relative small acceleration.
Around 70% of the air will bypass the core of the engine, only 30% of air will be compressed further and will eventually go through the combustion chamber.
What are the advantages of swept wings?
What are the advantages of swept wings?
Swept wings are:
Better for high speed flight as they have minimal camber and thickness reduce drag and delay Mcrit More stable in turbulence as they produce less lift and as a result they are less responsive to updraughts
What is the relevance of the mass and balance document?
What is the relevance of the mass and balance document?
It’s an official document for the safety of the flight.
A copy of this document needs to remain on the ground.
Describe the take off segments.
Describe the take off segments.
1st segment starts at screen height and finishes at gear retracted.
2nd segment starts when the gear is retracted and finishes when acceleration alt is reached (min. 400ft max 1000ft) speed V2.
3rd segment starts at acceleration alt, minimum 400ft, and finishes when the flaps are retracted.
4th segment starts when the flaps are retracted, MCT is set and finishes at the 1500ft.
What do high lift devices do?
What do high lift devices do?
High lift devices increase the lift produced by a wing, allowing the aircraft to operate at lower speed ranges usually for take off and landing.
What is a turbo fan?
What is a turbo fan?
A turbofan is a type of jet engine, similar to a turbojet.
It essentially consists of a ducted fan with a smaller diameter turbojet engine mounted behind it that powers the fan.
Part of the airstream from the ducted fan passes through the turbojet where it is burnt to power the fan, but the majority of the flow bypasses it, and produces most of the thrust. They are mainly used commercially because they are highly efficient and relatively quiet in operation.
How can you calculate Vref?
How can you calculate Vref?
Vref = 1.3 x Vs0 (stall speed in the landing configuration).
