The aircraft begins at the dot, and pulls into a vertical climb. The small angled line at the top indicates a stall turn (without indicating the orientation after the turn). The plane then descends, pulls into horizontal flight, and ends at the small vertical line. The hammerhead turn, stall turn, or Fieseler is an aerobatics turn-around maneuver.
In modern aerobatics, this maneuver, if executed pre-stall with a non-zero turning radius at the top of the climb, is known as a wingover. If the rudder turn is executed right at the initiation of the stall, the resulting yaw occurs around a point within the aircraft's wingspan and the maneuver is known as a stall turn or hammerhead.
In aviation, in Australia, Canada, New Zealand, South Africa, the United Kingdom and elsewhere, HASELL or alternatively HASEL, is a standard mnemonic to prompt a series of checks prior to carrying out many types of manoeuvres, such as stalls, spins, spiral dives or aerobatics. [1] The HASEL acronym stands for: [1] Height; Area; Security; Engine ...
The falling leaf is often used as a training maneuver, teaching the pilot to control the plane during a stall and helping beginners to overcome the fear that happens when a plane stalls unexpectedly. It is generally performed from a low-speed, straight, level stall, to avoid the buffeting, departure from the normal flightpath, and flat spin ...
The DizzyFIX is a home medical device designed to assist in the treatment of benign paroxysmal positional vertigo (BPPV) and its associated vertigo. [1] The device is a head-worn representation of semi-circular canals. The device is filled with fluid and a particle representing the otoconia (loose hard particles) associated with BPPV.
The most common stall-spin scenarios occur on takeoff (departure stall) and during landing (base to final turn) because of insufficient airspeed during these maneuvers. Stalls also occur during a go-around manoeuvre if the pilot does not properly respond to the out-of-trim situation resulting from the transition from low power setting to high ...
The alternate name, "Frolov's Chakra", refers to Russian test pilot Yevgeni Frolov, the pilot who first carried out the maneuver, while "chakra" is a yogic term, meaning "vortex" or "whirlpool". The Kulbit drastically decreases the aircraft's speed and could theoretically be used to cause a pursuing aircraft to overshoot its target.
Maneuvers are used to gain a better angular position in relation to the opponent. They can be offensive, to help an attacker gain an advantage on an enemy; or defensive, to help the defender evade an attacker's weapons. They can also be neutral, where both opponents strive for an offensive position or disengagement maneuvers, to help an escape.
