F 16 Zero speed Maneuver !



What is the speed Zero of the fighter plane?
Aircraft with high maneuverability, such as the MiG-29 and Sukhoi can steadiness in place in the air for a few seconds , The maneuvers known as the cobra maneuver and controlled collapse or Zero speed Maneuver
 


Zero speed Maneuver means that rise vertically until it reaches the speed of the plane to zero, And instead of collapse down the pilot works on making the aircraft in its place equal weight with momentum , But for a limited time as they need to Great momentum, Of course speed zero means that the air that enters the engine to be inadequate for cooling ..
Energy management
In combat, a pilot is faced with a variety of limiting factors. Some limitations are constant, such as gravity, structural integrity, and thrust-to-weight ratio. Other limitations vary with speed and altitude, such as turn radius, turn rate, and the specific energy of the aircraft. The fighter pilot uses BFM to turn these limitations into tactical advantagesA faster, heavier aircraft may not be able to evade a more maneuverable aircraft in a turning battle, but can often choose to break off the fight and escape by diving or using its thrust to provide a speed advantage. A lighter, more maneuverable aircraft can not usually choose to escape, but must use its smaller turning radius at higher speeds to evade the attacker's guns, and to try to circle around behind the attacker.
BFM are a constant series of trade-offs between these limitations to conserve the specific energy state of the aircraft. Even if there is no great difference between the energy states of combating aircraft, there will be as soon as the attacker accelerates to catch up with the defender. However, potential energy can easily be traded for kinetic energy, so an aircraft with an altitude advantage can easily turn the potential energy into speed. Instead of applying thrust, a pilot may use gravity to provide a sudden increase in speed, by diving, at a cost in the potential energy that was stored in the form of altitude. Similarly, by climbing the pilot can use gravity to provide a decrease in speed, conserving the aircraft's kinetic energy by changing it into altitude. This can help an attacker to prevent an overshoot, while keeping the energy available in case one does occur
