Bob-Up IHADSS Mode

Activate Bob-Up IHADSS mode (use when you’re hidden and need to bob-up to fire)

This IHADSS mode includes all items that appear in Hover IHADSS mode, but

also incorporates the hover position box and a second command heading.

Hover Position Box. This octagonal box originates at the center

of the viewscreen and gives an “overhead” view of approximately an

8' x 8' area of ground. (The entire IHADSS display, by comparison,

represents a 44' x 44' area.) The sight circle in the middle of the

IHADSS display represents the helicopter’s position. As the helicopter drifts, the

octagonal box moves around onscreen and indicates how far you’ve strayed from

the original hover position.

Try to keep the octagon centered over the sight reticule. The easiest way to do

this is to move your flight control device

toward

the octagon. If the box is to the

left and up, for example, press the joystick left and up. With a little practice, you’ll

be able to anticipate the box’s movements and keep your helo in the middle of it.

If this proves too difficult, use the hover hold feature. (You must be flying at a

speed below 15 knots to activate this autopilot function.) You can also re-center

the octagonal box on your sight reticule.

Toggle hover hold (maintain current altitude and hover)

Press the Bob-Up IHADSS mode key again if you drift too far and want to re-center the box

over the sight reticule

Bob-up Command Heading. During bob-up maneuvers, a

second chevron appears on the magnetic heading tape (4). This

represents the helicopter’s heading as it was when the Bob-Up

IHADSS mode was engaged, and it remains on that heading until

the pilot switches the IHADSS mode.
