The Israeli air force is to upgrade the automatic hovering system
installed in its Sikorsky CH-53 "Yasur" transport helicopters within
the coming months, following successful initial tests performed by its
flight-test centre.
Test pilots at the centre report that the new equipment, which is based on the DRS-developed altitude hold and hover stabilisation (AHHS) system, is easy to operate and "helps to perform the missions", by providing a more stable hover.
Activated by one button push, AHHS provides hands-free cyclic and collective control for cruise and low-altitude hover operations, as well as during automatic landing, precision hover and drift control. It enables pilots to operate safely in challenging conditions, such as brown-out or white-out, over-water operations and in tight landing zones.
The new equipment is integrated with the aircraft's existing flight control systems and data bus architecture.
