This is a question that comes up from time to time for our subject matter specialists. Today, we have the full, extensive explanation as well as the answer for everyone who is interested!
In a spin, both wings are in a stalled condition but one wing will be in a deeper stall than the other. The drag is greater on the more deeply stalled wing causing the aircraft to autorotate (yaw) toward that wing. Spins are characterised by high angle of attack, low airspeed and high rate of descent.
Which wings are stalled in a spin?
In a normal spin, the wing on the inside of the turn stalls while the outside wing remains flying. It is possible for both wings to stall, but the angle of attack of each wing, and consequently its lift and drag, are different.
What happens when one wing is more stalled than the other wing?
The consequences of one wing exceeding the critical angle before the other are discussed. The wing that stalls first has a reduction in lift, causing roll. … The increase in drag yaws the aeroplane toward the down-going wing, which may further delay the stall of the up-going wing as a result of increased airspeed.
What are the 4 phases of a spin?
There are four phases of a spin: entry, incipient, developed, and recovery.
What are the 3 phases of a spin?
Stages of a Spin
The FAA has outlined three stages for spins in light aircraft: incipient, fully developed and recovery.

Is the flat spin in Top Gun real?
Art Scholl. The 1986 blockbuster film TOP GUN included one scene where the character Maverick, inadvertently entered an inverted flat spin that killed his RIO “Goose”, but it was not Goose that was lost in that spin. That aviator’s name was Art Scholl.
Can a plane recover from a flat spin?
A flat spin is a dangerous flight condition that can be impossible to recover from. Thankfully, it’s not likely to happen on any routine flight.
How do you recover from a Cessna 172 spin?
PLACE AILERONS IN NEUTRAL POSITION. APPLY AND HOLD FULL RUDDER OPPOSITE TO THE DIRECTION OF ROTATION. JUST AFTER THE RUDDER REACHES THE STOP, MOVE THE CONTROL WHEEL BRISKLY FORWARD FAR ENOUGH TO BREAK THE STALL. Full down elevator may be required at aft center of gravity loadings to assure optimum recoveries.
What are left turning tendencies?
Torque, spiraling slipstream, P-factor, and gyroscopic precession are commonly referred to as the four left-turning tendencies, because they cause either the nose of the aircraft or the wings to rotate left. Although they create the same result, each force works in a unique way.
Does a stalled wing produces lift?
The wing never completely stops producing lift in a stalled condition. If it did, the aircraft would fall to the Earth. Most training aircraft are designed for the nose of the aircraft to drop during a stall, reducing the AOA and “unstalling” the wing.
Why does the wing root stall first?
A root stall is what you want to happen in nearly all airplanes. When an aircraft stalls at the root first, it means there’s enough airflow over the tips of your wings to prevent any rapid rolling motion during a stall, which makes the airplane more stable. It also makes your plane more resistant to entering a spin.
Why are there no ailerons in a stall?
Using ailerons in a power-on stall can cause an even more aggressive wing drop. That’s because your propeller is forcing air over the wing root, delaying its stall.
Can a Cirrus recover from a spin?
Normally a single-engine airplane has to be spun as part of the certification process. The Cirrus wasn’t. … That is the only way a pilot can recover from a spin in a Cirrus. The stall characteristics of the airplane are not bad when compared with some other airplanes but they aren’t real good, either.
At what altitude shall the altimeter be set to 29.92 when climbing to cruising flight level?
At or above 18,000 feet MSL. All operators will set 29.92 “Hg. (standard setting) in the barometric altimeter. The lowest usable flight level is determined by the atmospheric pressure in the area of operation as shown in TBL ENR 1.7-1.
How do you recover from a spiral dive?
- Reduce your power to idle.
- Level your wings.
- Slowly pull back to a nose-level attitude.
- Add power once you’ve recovered and your airspeed returns to normal.
Can you do spins in a 172?
The Cessna 172 is used a lot for training and is approved for spins when operated in the Utility Category. … The later model 172s will spin, and are approved, but they just don’t spin as nicely as the old ones.
Can you spin a Piper Cherokee?
Examples of Utility planes with spin approval include the Cherokee and Cessna 150/152/172. Examples of Utility planes where intentional spins are prohibited include the Warrior/Archer and Grumman AA-1/5 series. Make sure you know which it is in your Utility airplane lest you become a test pilot (see post 7, above).
What is the acronym for spin recovery?
PARE is an acronym developed by flight instructor Rich Stowell to help pilots remember the sequence of control inputs necessary for a spin recovery: Power (close the throttle), Ailerons (neutralize), Rudder (full deflection in direction opposite the spin), Elevator (first, stick forward to un-stall the wing).
Can a 737 recover from a spin?
No, they have not been spun during test or for training. No, type-ratings don’t include spin recovery, just stall recovery in simulators (including FBW types which have to be degraded first to allow them to stall) and recently recovery from unusual attitudes.
In what condition must an aircraft be placed in order to spin?
In order for an airplane to enter a spin, the airplane’s wings must be stalled first. Then, an airplane begins to spin when one wing is “less” stalled than the other wing.
Why do you reduce the throttle when recovering from a spin?
Step 1) P: Power To Idle
The first step in spin recovery is reducing your throttle to idle. … When you take the power out, you eliminate both of these factors, making it easier to get the nose down and fly out of the spin.
Who Turned Down Top Gun role?
Tom Cruise turned down his iconic role in 1986’s Top Gun ‘over and over again’ until producer Jerry Bruckheimer convinced him to take the part. Tom Cruise almost skipped out on one of the most famous roles of his career.
Who died during the filming of Top Gun?
Scholl died during the filming of Top Gun when his Pitts S-2 camera plane failed to recover from a spin and plunged into the Pacific Ocean. He had entered the spin intentionally in order to capture it on film using on-board cameras.
Did they use real planes in Top Gun?
While real pilots were shot flying during their regular routines, NASA astronaut Scott Altman piloted the F-14 aircraft for many of the film’s stunt sequences, having been stationed at NAS Miramar at that point in time.
