'''Hovering''' refers to a maneuver where the helicopter maintains a constant position, usually a few feet above the ground, by balancing lift and weight.

== Definition ==
Hovering is a maneuver where a helicopter remains in nearly motionless flight over a reference point, maintaining a constant altitude and heading.

== Lift and Weight Balance ==
The main rotor must generate enough lift to counteract the helicopter’s total weight.

== Rotor Blade Pitch ==
The angle of attack (pitch) of the rotor blades is adjusted to control the amount of lift generated, allowing the helicopter to hover.

== Vertical Flight ==
Hovering is an element of vertical flight, where the helicopter can move up or down by adjusting the balance of forces.

== Control Inputs ==
Pilots use the cyclic (to control lateral and longitudinal movements) and the collective (to control altitude) to maintain a stable hover.

== Practice and Skill ==
Hovering requires practice and a delicate touch on the controls, with pilots learning to anticipate control inputs and maintain stability.

== Visual References ==
Visual references on the ground, such as markers or landmarks, can help pilots maintain orientation and position while hovering.

== Wind Conditions ==
Wind conditions can affect hovering, requiring pilots to make adjustments to maintain a stable hover.

== Tail Rotor ==
The tail rotor helps to counteract the torque of the main rotor, allowing the helicopter to turn and maintain directional control during a hover.

== Loss of Tail Rotor Effectiveness (LTE) ==
Pilots need to be aware of LTE regions, which can occur when operating out of ground effect (OGE) or near maximum torque available (MTA).

== Types of Hovering Turns ==
Pilots can perform different types of hovering turns, such as turning about the tail or nose, to maintain clearance from obstacles.

== VTOL Aircraft Hovering ==
Aircraft like the '''Lockheed Martin F-35B Lightning II''' and the '''Harrier jump jet''' use vertical takeoff and landing (VTOL) technology to hover.

=== F-35B Lightning II ===
* The F-35B has a vertical lifting fan that functions like a miniature helicopter, enabling vertical takeoff and landing.
* The LiftSystem is the only vertical lift tech developed for supersonic jets in production.

=== Harrier Jump Jet ===
* The Harrier uses a jet engine with thrust-vectoring nozzles that swivel downwards to generate lift and enable hovering.

=== VTOL Technology ===
* VTOL (Vertical Takeoff and Landing) aircraft, including tiltrotors like the V-22 Osprey and jets like the Harrier and F-35B, operate without runways.
