Where does a swept wing stall first?
Where does a swept wing stall first?
At the tip
Do airplanes have an optimum C.G.? If yes, where is it?
Do airplanes have an optimum C.G.? If yes, where is it?
Yes, the closer the C.G. is to the rear limit, the less tail down force is required, which means less drag which results in less fuel burn.
What is adverse yaw?
What is adverse yaw?
When rolling the aircraft the up-going wing will experience more drag than the down-going wing. This will result in a yawing moment that directly opposes the desired direction of turn. (i.e.: rolling left will cause a right yaw.)
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.
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 load an aircraft for max range?
How would you load an aircraft for max range?
The position of the CG directly influences the fuel consumption of an aircraft. An aft position of the CG makes the aircraft less stable, requiring less lift to be generated in both the horizontal stabilizer and wings, reducing the overall drag of the aircraft, and increasing the max range.
You want to load the the aircraft so that the CG is at, or as close as possible, to the aft limit (Without exceeding it).
On A high wing anhedral airplane, like a BAE146, and a high wing straight winged aircraft like a Fokker 50, why they don’t have dihedral wings if it has so many advantages?
On A high wing anhedral airplane, like a BAE146, and a high wing straight winged aircraft like a Fokker 50, why they don’t have dihedral wings if it has so many advantages?
A high wing location like the BAE and the Fokker give a natural stable contribution.
This is because the Center of Gravity is underneath the wing, therefore when disturbed the C.G. provides a positive momentum opposite to the distortion.
What is convergency?
What is convergency?
Meridians converge from their maximum distance apart (at the equator) to the poles where they meet.
Great circles are the shortest distance between two points and convergency represents the change in direction experienced between those points.
Why do some airplanes have dihedral wings?
Why do some airplanes have dihedral wings?
Dihedral provides:
Lateral stability (during a roll) Wing clearance, wingtip to ground has more space
You are at the end of the runway with the static ports blocked. What will be the reading on the altimeter after departure?
You are at the end of the runway with the static ports blocked. What will be the reading on the altimeter after departure?
The elevation at which the airplane departed from the runway.
