Flying a Helicopter

A helicopter is a kind of single-wing rotorcraft where maximum lift and thrust are provided by spinning dual rotor blades at the rear of the aircraft. This enables the helicopter to move forward and land flatly, vertically, and to move left and right. It also offers excellent flight characteristics when the helicopter is being used for climbing and flying at low levels. The helicopter's main rotor blades can rotate in both directions.

Helicopters are generally used for a variety of applications, including transport, surveillance, disaster relief, farming, tourism, hunting, conservation, and hobby. Some helicopters, like the MIG and helicopter OH laser based cockpits, are suitable for civilian use. These have been modified to meet standards of the Federal Aviation Administration ( FAA ). They can be equipped with laser or sonar targeting systems, which are ideal for night vision. There are also LED tail lights, which provide more visibility during nighttime operations.

In addition, helicopters can be fitted with forward flight controls and counter-rotating stabilizers to provide the best possible support when climbing or executing a turn. If needed, additional electrical power can be supplied from an auxiliary power unit. In addition, some fixed-wing aircraft feature emergency landing gears, such as emergency descent control. This is incorporated into the main rotor blade after the aircraft has been inverted. It can be manually or automatically activated when the landing wheels are touching the ground.

A helicopter commonly features a single seat, although two may also be available. It is generally considered safe to operate a helicopter with only one person in the seat, although inexperienced pilots should never operate more than two, especially if flying top level or with poor visibility. When two or more persons are flying, only the seat in front of the pilot should be controlled. Otherwise, it would become difficult to avoid collisions.

The rotor blades of a helicopter are located behind the cockpit in a fixed position. Their angle of attack will affect the rate of which the helicopter moves forward or spins in flight. To control the direction of the helicopter in flight, the air controller will rotate the rotor blades. In most helicopters, the rotor blades must be manually manipulated during flight. Hydraulic and pneumatic pressure is used to vary rotor blade speed.

Hover is the term used to describe the ability of a helicopter to stay in the air while remaining rooted in the ground. This is generally achieved by using the lift-to-drag ratio, which is defined as the air speed at which the helicopter remains afloat. The hover airspeed is equal to the airspeed at which the aircraft is lifted by its stringer wheels. Hover is useful in military applications where helicopters are used to transport troops, carry out ground operations and drop bombs. For commercial applications, a hovercraft is essentially a small aircraft that can only attain a specific distance above the ground before spinning off into hover mode.
