V Radar Altimeter AN/APN-209

Description.

The radar altimeter set is a high resolution pulse radar that provides an indication of absolute clearance over all types of terrain. The set consists of the following: a panel mounted height indicator receiver transmitter (located on copilot instrument panel); a panel mounted remote height indicator (located on pilot instrument panel) and two flush mounted antennas on the underside of the helicopter. The controls and displays of the height indicator receiver-transmitter (IRT) and the remote height indicator (Rl) are identical (see fig). Absolute altitude is displayed by a pointer and a digital readout. The pointer operates against a fixed dial and indicates tens of feet between 0 to 200 feet, and hundreds of feet between 200 to 1500 feet.

Above 1500 feet the pointer is driven behind a mask. The digital display has a four digit readout. The readout is displayed in one foot increments up to 255 feet. At 256 feet the display is rounded up to 260 feet. Between 260 and 1500 feet the readout is displayed in tens of feet.

The LO SET control knob functions as the on-off switch and is the low altitude trip point adjustment. Clockwise rotation turns the set on. Continuing a clockwise rotation provides for the setting of the low altitude bug .

The HI SET control knob provides for the setting of the high altitude bug. Depressing the HI SET control knob places the altimeter set in the self-test mode. The IRT sends a simulated signal of 1000 feet to both indicators.

The indicators display the information via the pointer and digital readout. Whenever the indicated altitude drops below the low altitude bug setting the LO altitude waming lamp is activated. Whenever the indicated altitude goes above the high altitude bug setting, the HI altitude warning lamp is activated. When the LO SET control knob is turned to OFF, or during periods of unreliable operation, the OFF flag comes into view.

You also have to send power to the instrument via an overhead switch or (Rt Shift - R). Then the On-Off knob works on the instrument. In a warm start mission it's already on but after an Auto-Start you still have to power the Radar Alt. And delete your old keyboard.lua or these new commands don't work.

 

For the sight below you can activate the hotspots for the on-off and reticle intensity by scrolling around the front with your mouse even though you can't actually see the controls

Locking Lever [RShift + M]

A spring tension lever that fits into either keyway to lock mounting bracket in desired position.

 

Reticle Lamp Switch [No Keyboard Control yet]

A three-position toggle switch used to illuminate the reticle. Has two "on" positions and one "off" position.

 

Reticle Intensity (Control) [No Keyboard Control yet]

On Upper left side of the sight. Turning clockwise increase reticle illumination intensity; turning counterclockwise decrease intensity.

 

Elevation/Depression Knob w/ Scale [No Keyboard Control yet]

On left side of sight. Used to move reticle image vertically. Unless knob is depressed, a click is audible as each graduation passes index. Scale numbered in 5-mil increment show 360 mils excursion. White numbers indicate elevation; Red mumbers indicate depression.

 

Inclinometer Assembly

Indicate Aircraft turn and bank attitude.
