Cruise IHADSS Mode

Activate Cruise IHADSS mode (use when cruising in forward flight)

In Cruise IHADSS mode, the IHADSS displays all the information found in

Transition IHADSS mode, except that the horizon line (23) disappears. Instead,

there are three additional readouts — barometric altitude, pitch ladder and bank

angle indicator. The estimated time to arrival for the current waypoint also appears

to the left of the High Action Display (10).

Barometric Altitude. Since the radar altitude indicator (6) only

reads up to 1420 feet, another device is necessary at higher

altitudes. The barometric altitude readout is a digital display that

gives altitudes from 0 to 30,000 feet above sea level. To figure

altitude, it compares the current air pressure to a pressure calibrated at sea level.

(Air pressure decreases as altitude increases.)

Pitch Ladder. The pitch ladder is a series of horizontal lines that

scroll vertically in the center of your view. It describes both vertical

movement and bank/roll angles. When the craft dives, the lines scroll

upward; during ascents, they scroll downward. The pitch ladder is

also capable of rolling 360° (the lines tilt to reflect the bank angle).

Pitch ladder lines above the horizon are solid; those below the horizon are

dashed. (The small tips on the ends of the lines point toward the horizon.)

Bank Angle Indicator. This indicator is a curved scale that

usually displays 30° to the left and right of center in 5° increments.

The same command heading mark (lubber line) that marks the

heading on the heading tape (4) also marks the bank angle of the

helicopter.
