What is the maximum altitude of an Airbus A320?

The A380, A350, and 787 are all CERTIFIED to 43,000 ft. So A320 can go to 43,000 but not higher. The reason it’s less (39,000-41,000) is because in case of an emergency they want to be able to descend in time.

What will happen if you extend the slats and flaps during approach?

When you extend the flaps on your plane, you lower your aircraft’s stall speed, and at the same time, increase drag. This all happens because extending flaps increases the camber, or curvature, of your wing.

Why does VMO decrease with altitude?

VMO is indicated airspeed measured in knots and is mainly a structural limitation that is the effective speed limit at lower altitudes. As altitude increases, indicated airspeed decreases while Mach remains constant. MMO is the effective speed limit (“barber pole” on the airspeed indicator) at higher altitudes.

What is absolute altitude?

Absolute Altitude is height above ground level (AGL). • Pressure Altitude is the indicated altitude when an altimeter is set to 29.92 in Hg (1013 hPa in other parts of the world). It is primarily used in aircraft performance calculations and in high-altitude flight.

What does decel mean A320?

The DECEL basically tells the aircraft that you are on approach. It will automatically set the speed based on your flap configuration.

What is the cruising altitude of a 737?

The advanced wing airfoil design provides an economical cruise speed of . 789 Mach (530 mph) – compared to . 745 Mach for earlier 737 models. The Next-Generation 737 airplanes are capable of cruising to a maximum altitude of 41,000 feet, compared to 39,000 feet for the competition.

What is the highest cruising altitude?

Answer: The highest commercial airliner altitude was 60,000 feet by Concorde. The highest military air-breathing engine airplane was the SR-71 — about 90,000 feet. The highest airliner flying today reaches 45,000 feet. The highest business jet flying today reaches 51,000 feet.

How does slats increase lift?

Their purpose is to increase lift during low speed operations such as takeoff, initial climb, approach and landing. They accomplish this by increasing both the surface area and the camber of the wing by deploying outwards and drooping downwards from the leading edge.

Why flaps and slats are added into the wing design for airliners?

To keep the lift high (to avoid objects on the ground!), airplane designers try to increase the wing area and change the airfoil shape by putting some moving parts on the wings’ leading and trailing edges. Moving the flaps aft (toward the tail) and the slats forward increases the wing area.

What is the crank time limit on an Airbus A380?

Per the Airbus maintenance training manual, the crank limit whether it’s dry (CRANK) or wet (IGN/START + MAN START) is 2 minutes. An ECAM warning will notify of exceeding the limit: ENG 1 (2) START FAULT (condition: starter time exceeded).

What should the flaps be set at during takeoff and landing?

The next time you fly in an airliner, watch the wings during takeoff and landing. On takeoff, we want high lift and low drag, so the flaps will be set downward at a moderate setting. During landing we want high lift and high drag, so the flaps and slats will be fully deployed.

What is the purpose of a slat on a plane?

Pivoting the leading edge of the slat and the trailing edge of the flap downward increases the effective camber of the airfoil, which increases the lift. In addition, the large aft-projected area of the flap increases the drag of the aircraft. This helps the airplane slow down for landing.

What is the difference between a flap and a slat?

The part on the leading edge is called a slat , while the part on the trailing edge is called a flap. The flaps and slats move along metal tracks built into the wings. Moving the flaps aft (toward the tail) and the slats forward increases the wing area.
