Mcrit
What is the critical point?
What is the critical point?
The critical point (CP) is a point on a track where it is as quick to go on as it is to turn back.
Also known as ETP (Equal Time Point) and PET (Point of Equal Time).
Why does a swept wing increase Mcrit?
Why does a swept wing increase Mcrit?
A swept wing makes the velocity vector normal to the leading edge a shorter distance than the chordwise resultant.
If you are outside the range of any VOR’s/NDB's, how does the aircraft know where it is?
If you are outside the range of any VOR’s/NDB's, how does the aircraft know where it is?
Via INS/IRS/GPS
What is departure?
What is departure?
Departure is an east-west distance along a parallel line of latitude, other than the equator.
Departure is calculated by: Change of longitude(minutes) x cosine of latitude.
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.
What clearance do MSA values give?
What clearance do MSA values give?
They provide at least 1000ft clearance over obstacles within 25NM of the homing facility.
Does a jet have a critical engine? Why yes or no?
Does a jet have a critical engine? Why yes or no?
No, there is no P-factor (asymmetric blade effect) as on a propeller-driven aircraft.
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.
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.
