WARNINGS
1.TO AVOID FLYING UNDER OR OVER STORMS, FREQUENTLY SELECT MANUAL TILT TO SCAN BOTH ABOVE AND BELOW YOUR FLIGHT LEVEL.
2.ALWAYS USE MANUAL TILT FOR WEATHER ANALYSIS.
7 RANGE
RANGE is a rotary control used to select one of six ranges (10, 25, 50, 100, 200, and 300 NM). The seventh position of the range switch is flight plan mode. Selecting FPLN blanks the radar information from the EFIS display and the mode annunciation flashes if a radiating mode is selected. The EFIS is set to a range determined by the installation.
Target alert can be used in the FPLN mode. With target alert on in the FPLN mode, the target alert armed annunciation (green TGT) is displayed. The RTA becomes active and starts searching for a hazardous target from 5 to 55 miles and ±7.5_ dead ahead. No radar targets are displayed. If a hazardous target is detected, the target alert armed annunciation switches to the alert annunciation (amber TGT). This advisory indicates that a hazardous target is in the aircraft’s flightpath and the WX mode should be selected.
8 SLV (Slave)
The SLV annunciator is a dead front annunciator that is only used in dual controller installations. With dual controllers, one controller can be slaved to the other by selecting the RADAR mode switch to OFF on that controller, only. This slaved condition is annunciated with the SLV annunciator.
In the slaved condition both controllers must be off before the radar system turns off.
9 MODE
The MODE switch is a rotary switch used to select one of the following functions:
DOFF - In this position the radar system is turned off.
DSTBY - In this position the radar system is placed in standby; a ready state, with the antenna scan stopped, the transmitter inhibited, and the display memory erased. STBY, in green, is
displayed in the mode field.
If STBY is selected before the initial RTA warmup period is complete (approximately 45 - 90 seconds), the flashing WAIT legend is
displayed in the mode field.
