Why don’t you want to fly your Seneca into a thunderstorm?
Why don’t you want to fly your Seneca into a thunderstorm?
Due to the structural damage that may occur in thunderstorms, due to hail, severe turbulence and severe windshear.
Besides that, lightning strikes may cause damage to electrical systems and severe icing may occur.
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.
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.
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 are the problems associated with icing?
What are the problems associated with icing?
Drag penalties (additional weight)
Less controllability
Explain what coffin corner is and what happens when reaching the coffin corner?
Explain what coffin corner is and what happens when reaching the coffin corner?
Occurs at absolute ceiling where low speed buffet and high speed (Mach) buffet are coincident.
When reaching the coffin corner, both increasing and decreasing the corner speed will result in a loss of control (either the aircraft stalls, or mach buffeting starts).
What is a moment arm?
What is a moment arm?
The distance from the datum to the point at which the weight of a component acts.
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.
Why is there an over boost protection on the Piper PA34 Seneca?
Why is there an over boost protection on the Piper PA34 Seneca?
To protect the engine from blowing up as it is easy to open the throttles to far during take off at sea level.
What effect does a wet runway have on V1?
What effect does a wet runway have on V1?
V1 is lower when the runway is wet than when the runway is dry, because of the longer ASDR on a wet runway.
