Helicopters with fly-by-wire systems allow a cyclic-style controller to be mounted to the side of the pilot seat. The cyclic is used to control the main rotor in order to change the helicopter's direction of movement. In a hover, the cyclic controls the movement of the helicopter forward, back, and laterally.
The flight controls are directly linked to the swashplate of the helicopter so there are no hydraulic systems in the 269. There are generally two sets of controls, although this was optional on the civil 269A. For three-seat aircraft, the middle collective control stick is removable and a seat cushion can be put in its place for the third ...
A Sea King helicopter landing on HMCS Assiniboine (DDH 234); the beartrap is the small rectangle on the flight deck. Recover assist landing of a SH-60B helicopter with a RAST system. A helicopter hauldown and rapid securing device (HHRSD) or beartrap enables helicopters to land on and depart from smaller ships in a wide range of weather ...
The two engines were provided due to the aircraft lacking collective pitch control, thus precluding an autorotation in the event of a power loss. The aircraft can reportedly hover on one engine. [1] The aircraft fuselage is made from welded steel tubing. Its dual two-bladed rotors have diameters of 14.5 ft (4.4 m) and incorporate dual flapping ...
A helicopter's main rotor hub. The vertical rods are at the end of the control chain that starts with the pilot controls. Helicopter flight controls are connected to the main and tail rotors, and include a cyclic stick, broadly to control forward-aft and left-right movements, a collective lever, broadly to control vertical movements, and anti-torque pedals, to control left and right yaw.
In response, Robinson Helicopter Company instituted stringent quality procedures and requirements, and replaced all main rotor blades on the fleet of 33 helicopters in service at the time. [ 26 ] In the early 1980s, the R22 experienced a number of student-pilot related accidents due to the R22's use as a primary flight trainer.

Many of the helicopters made their way to the civilian market and museums. Under the aircraft designation system used by the U.S. Navy pre-1962, Navy and U.S. Marine Corps versions were originally designated as the HTK, HOK or HUK, for their use as training, observation or utility aircraft, respectively. The Air Force Version was the H-43A ...
