RADAR ALTIMETER FUNCTIONS

The ST3400H functions as a Radar Altimeter indicator when interfaced to
a compatible Radar Altimeter system. A Radar Altitude display and a
MINS setting window are provided.

The Radar Altitude will not be displayed if a Radar Altimeter is not
installed. However the MINS setting window is retained and may be used
by the pilot as a reference number.

Radar altitude displays in 5’ increments below 200’; 10’ increments below
1000’; and 20’ increments below 2000’

The knob adjusts the MINS setting by rotating clockwise or
counterclockwise, as needed.

When the aircraft Radar Altitude descends below the MINS setting, the
MINS annunciator will flash and an audible MINS callout will occur.

Figure 8-1 Radar Altimeter Functions

Note:

The MINS function is disabled when the helicopter is on the

ground.
