What does a bypass ratio of 11:1 mean?
What does a bypass ratio of 11:1 mean?
For every 1kg of air passing through the combustion chamber, 11kg of air pass bypass the combustion chamber.
If you where picking up 10.000 litres of fuel in Newfoundland (cold weather), and 10.000 litres of fuel in Lima, Peru (hot weather), where would you have picked up the most fuel?
If you where picking up 10.000 litres of fuel in Newfoundland (cold weather), and 10.000 litres of fuel in Lima, Peru (hot weather), where would you have picked up the most fuel?
In Newfoundland. With cold weather density increases, therefore you would pick up a higher mass in Newfoundland.
What is BEM?
What is BEM?
Basic Empty Mass (BEM) is the mass of the aircraft with the basic equipment, unconsumable fluids and unusable fuel and oil.
What are the lift qualities of a swept wing?
What are the lift qualities of a swept wing?
Poor, because the sweep-back design has the effect of reducing the lift capabilities of the wing.
Where does a swept wing stall first?
Where does a swept wing stall first?
At the tip
What is an NDB?
What is an NDB?
Non Directional Beacon, a medium range radio navigation aid that sends out a signal in all directions for an aircraft to home to.
Why will a jet usually not fly at 41.000 feet?
Why will a jet usually not fly at 41.000 feet?
Because of the distance which has to be covered to reach 41.000 feet which may not be convenient for a short flight.
On long flights it is more typical to fly at 41.000 feet when the aircraft weight and performance allows.
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
What is a high bypass ratio engine?
What is a high bypass ratio engine?
In a high bypass design, the vast majority of the thrust is derived from the ducted fan, rather than from combustion gases expanding in a nozzle.
A high bypass ratio provides a lower thrust specific fuel consumption (grams/sec fuel per unit of thrust in kN using SI units), especially at zero velocity (at takeoff) and at the cruise speed of most commercial jet aircraft.

What is the cabin altitude of the Boeing 737 on a cruise flight level?
