What does it mean when a plane stalls?
A stall occurs when the angle of attack of an aerofoil exceeds the value which creates maximum lift as a consequence of airflow across it. Because of this, the indicated airspeed at which an aircraft has been shown to stall in given circumstances is determined during aircraft certification and included in the AFM.
Can a plane recover from a stall?
Recovery from a stall To recover from a stall, the pilot must push the nose down. Then the pilot must increase the engine power using the throttle. When air speed increases again, the pilot can level the wings and pull up to return the aircraft to normal flight.
Why is aircraft stall important?
The slower an aircraft flies, the higher the angle of attack must be in order for the aircraft to have enough lift. If it does not reach the necessary stallspeed, the stall occurs. Shortly after take-off, an aircraft needs considerable thrust in order to simultaneously increase its speed and gain altitude.
What is stall speed of an aircraft?
Stall speed is defined as the minimum steady flight speed at which the airplane is controllable.
Why do planes do not fly over the Pacific?
Airplanes often avoid air paths that take them over Mt Everest or the Pacific Ocean. This is because “the Himalayas have mountains higher than 20,000 feet, including Mt Everest standing at 29,035 feet. However, most commercial airplanes can fly at 30,000 feet.”
What are the signs when entering stall?
Generic indicators of an aerodynamic stall can include:
- Activation of artificial stall warnings.
- Aircraft buffet.
- Reduced flight control authority, especially reduced or loss of roll control.
- Significant aft control column displacement.
- High rate of descent.
- A nose down pitching tendency at the point the stall occurs.
What does a plane stall feel like?
During the stall break, you may experience a slight falling sensation as the nose pitches over. (Depending on aircraft type and pilot technique, airplanes can stall in a nose-high attitude without the break and pitch down.)
Can a 747 stall?
If you get a large swept wing aircraft into a stall, you can easily lose 15,000 feet recovering. I had a couple of hours in an Airlines 747 -400 sim many years back, and they demonstrated a couple of stalls, from clean config iirc. To be precise you always stall due to a high angle of attack.
Can a plane stall at high speed?
The only dangerous aspect of a stall is a lack of altitude for recovery. Stalls occur not only at slow airspeed, but at any speed when the wings exceed their critical angle of attack. Attempting to increase the angle of attack at 1g by moving the control column back normally causes the aircraft to climb.
What is the largest commuter plane in the world?

- Airbus A350-900.
- Airbus A340-500.
Why is takeoff and landing dangerous?
Why airplane takeoffs and landings are so dangerous. Boeing research shows that takeoff and landing are statistically more dangerous than any other part of a flight. During takeoff and landing, pilots have less time to react to problems because they’re on or close to the ground and moving quickly.
Where does a swept wing stall first?
With both forward and back swept wings, the rear of the wing will stall first. This creates a nose-up pressure on the aircraft. If this is not corrected by the pilot it causes the plane to pitch up, leading to more of the wing stalling, leading to more pitch up, and so on.
How many G’s is a 45 degree bank?
Load factor and accelerated stalls: A constant-altitude turn with 45 degrees of bank imposes 1.4 Gs, and a turn with 60 degrees of bank imposes 2 Gs. Stall speed increases with the square root of the load factor, so an airplane that stalls at 50 knots in unaccelerated, level flight will stall at 70 knots at 2 Gs.
What are the 4 types of flaps?
There are four basic types of flaps: plain, split, Fowler and slotted.
What plane has the lowest stall speed?
naturally, on a still day, the slowest of equipment will stall at below 10mph. The Ruppert Archaeoptrix Electro (Wikipedia, official website) apparently has a stall speed of 30 km/h (19 mph / 16 kn), and I think that makes it a candidate for the current ” slowest ” fixed wing aircraft.
