 -MAP This mode is only used for display of the ground map. A combination of transceiver gain, antenna position (TILT) and range selection enables the display of a larger area and the identification of major changes in the ground map (e.g. a sea cost, a lake, a mountain, an island...). The color display follows the color mentioned in correspondence table (see table 1 - para. 7. A.) If the image is too bright, due to too great reflection intensity, it can be dimmed by the GAIN potentiometer, item 1.

 (b) System selection and start up: OFF/ON switch (item 1) This switch enables:
 -
the activation of the transceiver

 -
the suppression of the radar image on the NDs when these NDs are in the ARC or ROSE mode.

 

R **ON A/C 051-099, 106-149, 201-299, 301-399, 401-499,
 (b) System selection and start up: 1/OFF/2 switch (item 6) This switch enables:
 -
the selection and activation of the transceiver 1 or 2 (if the second transceiver is installed),

 -
the suppression of the radar image on the NDs when these NDs are in the ARC or ROSE mode.

R  (b) System selection and start up: 1/OFF/2 switch (item 1) 
R  This switch enables: 
R  - the selection and activation of the transceiver 1 or 2 (if the 
R  second transceiver is installed) 
R  - the suppression of the radar image on the NDs when these NDs 
R  are in the ARC or ROSE mode.

 (c) Gain control (item 5)
 The GAIN potentiometer enables the manual control of transceiver
 sensitivity in the WX, WX/TURB and MAP modes.
 When the potentiometer is rotated fully counterclockwise, the
 AUTO position provides preset calibrated transceiver gain level
 (maximum receiver sensitivity). Clockwise rotation of the GAIN
 potentiometer increases the gain towards the MAX position.
 In the AUTO position, no indication appears in the R lower corner
 of the NDs. For the other positions, the MAN indication is
 displayed in white.
 In the windshear position, the gain control is automatic in the
 WR/PWS for the scanning.
 (d) TILT control (item 3)
 The TILT selector switch enables the variation of the antenna
 elevation angle in 1/4 deg. steps on a non-linear scale graduated
 in degrees, within a range of +15 deg. (UP) to -15 deg. (DOWN) in
 relation to a horizontal plane defined by the stabilization
 system.
 This antenna elevation angle is displayed in cyan in the R lower
 corner of the ND and progresses in steps of 0.25 deg.
 If the antenna position is different from the TILT selector
 switch position, a red ANT failure warning message replaces the
 TILT indication in the R lower corner of the ND. In windshear
 mode, the tilt is automatic and the tilt displayed on ND is
 always the selection on the radar control section although
 different in the antenna.
 In the windshear position, the tilt control is automatic in the
 WR/PWS for the scanning. However, the tilt displayed on ND is in
 accordance with the one selected on the radar control unit.

 (e) WINDSHEAR/AUTO/OFF switch (item 4)
 In AUTO position, the windshear detection is automatic if
 altitude is lower than 2300 ft and qualifiers A and B are valid.
 This automatic operation can be inhibited when the switch is in
 the OFF position.

R  (c) Gain control (item 1) 
R  The GAIN potentiometer enables the manual control of transceiver 
R  sensitivity in the WX, WX+T, TURB and MAP modes. 
R  Clockwise rotation of the GAIN potentiometer increases the gain 
R  towards the MAX position. 
R  When the potentiometer is rotated fully clockwise, the CAL 
R  position provides preset calibrated transceiver gain level 
R  (minimum receiver sensitivity). 
R  When the GAIN potentiometer is the CAL position, no indication 
R  appears in the R lower corner of the NDs.
