CFIs repeat it like a mantra: An airplane can stall at any airspeed, in any pitch attitude. Your trainer’s wing always stalls when it exceeds its critical angle of attack—and that can happen even if the airplane is pointed straight down and approaching VNE.
What is the stalling speed of an aircraft?
Can an airplane stall at any attitude?
Is it common for planes to stall?
Despite training and warning systems, stalls do still occur. At low speed and low altitude during take-off and landing, they can be disastrous, and unfortunately, a number of crashes have occurred. Some of the most notable include: British European Airways Flight 548, June 1972.
How fast does a 747 land?
A 747 ‘Jumbo Jet’ would typically land at a speed of about 145kts-150kts (166mph-172mph), depending on the landing flap setting selected.
What is a super stall?
A Deep Stall, sometimes referred to as a Super Stall, is a particularly dangerous form of stall that results in a substantial reduction or loss of elevator authority making normal stall recovery actions ineffective. In many cases, an aircraft in a Deep Stall might be unrecoverable.
Can planes recover from a stall?
Yes an airliner can recover from a stall. The question of the pilots abilities to recover from that stall come into play. Most modern airliners (Boeing, Airbus, Candair) install “stick shakers/ stick pushers,” which are designed to alert the pilot to a stall and attempt a recover from the stall before it happens.
How do you slow down a plane?
To begin the slow flight maneuver, clear the area and gradually reduce thrust from cruise power and adjust the pitch to allow the airspeed to decrease while maintaining altitude. As the speed of the airplane decreases, note a change in the sound of the airflow around the airplane.
Can a plane stall at any speed?
CFIs repeat it like a mantra: An airplane can stall at any airspeed, in any pitch attitude. Your trainer’s wing always stalls when it exceeds its critical angle of attack—and that can happen even if the airplane is pointed straight down and approaching VNE.
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.)
Why do planes feel slow?
Answer: The sensation of slowing down is really one of slowing the rate of acceleration; this is due to reducing the thrust after takeoff to the climb setting. The sensation of “dropping” comes from the retraction of the flaps and slats. The rate of climb is reduced, causing it to feel like a descent.
How do planes stop when landing?
In addition to wing spoilers, airplanes use disc brakes. Airplane disc brakes are similar to the braking system in automobiles. They consist of a pair of calipers that, when engaged, squeeze pads against the rotors of an airplane’s landing gear. Disc brakes are designed to remain static at all times.
Can a plane recover from Coffin Corner?
To recover, you push the stick forward, letting the craft’s nose go down and the speed over the wings increase. You start flying again and can bring the stick back to a straight and (almost) level glide.
Why do planes spin?
A spin is caused when the airplane’s wing exceeds its critical angle of attack (stall) with a sideslip or yaw acting on the airplane at, or beyond, the actual stall.
What are the 4 phases of flight?
- 4.2 Take-off. Takeoff is the phase of flight in which an aircraft goes through a transition from moving along the ground (taxiing) to flying in the air, usually starting on a runway. …
- 4.3 Climb. …
- 4.4 Cruise. …
- 4.5 Descent. …
- 4.6 Landing.

What force causes planes to turn?
Centrifugal force is the “equal and opposite reaction” of the airplane to the change in direction and acts equal and opposite to the horizontal component of lift. This explains why, in a correctly executed turn, the force that turns the airplane is not supplied by the rudder.
Why do planes stall when flying straight up?
As the angle of attack increases, wing lift goes up and up and up, then suddenly drops sharply as the smooth air flow detaches from the back of the wing. That’s the stall.
What is the scariest part of flying?
Boeing research shows that takeoff and landing are statistically more dangerous than any other part of a flight. 49% of all fatal accidents happen during the final descent and landing phases of the average flight, while 14% of all fatal accidents happen during takeoff and initial climb.
Why do planes turn after takeoff?
During takeoff, air accelerated behind the prop (known as the slipstream) follows a corkscrew pattern. As it wraps itself around the fuselage of your plane, it hits the left side of your aircraft’s tail, creating a yawing motion, and making the aircraft yaw left.
What do pilots say before landing?
Alpha, Bravo, Charlie, Delta, Echo, Foxtrot, Golf, Hotel, India, Juliet, Kilo, Lima, Mike, November, Oscar, Papa, Quebec, Romeo, Sierra, Tango, Uniform, Victor, Whiskey, X-ray, Yankee, Zulu. Numbers get special treatment too.
How fast do planes go to take off?
Typical takeoff air speeds for jetliners are in the range of 240–285 km/h (130–154 kn; 149–177 mph). Light aircraft, such as a Cessna 150, take off at around 100 km/h (54 kn; 62 mph). Ultralights have even lower takeoff speeds.
