1) ARL (Automatic Range Limit)
- (Bendix/King RDR-2100 and
RDS86/VP only) Automatic range limit (ARL) depicts the limit of
your radar range. ARL calculates the attenuation of the
microwave signal based on an integration of the returned echoes
along the radial path. The R/T draws BLUE from that calculated
point to the edge of the covered range. When ARL is selected, an
on-screen annunciation is displayed to indicate that it is active.
2) Target
- Turns the Target Alert mode on or off. A target alert
appears when the radar detects heavy echoes ahead that might
not be appear within the displayed range of the Radar. Target
Alert works as follows:
■
Collins
- Target Alert consists of two screen indications.
When Target Alert is ON but not active, the alert is displayed
as, “TGT”, in white text in the upper right corner of the screen.
When the alert becomes active, it turns yellow and is
surrounded by a yellow box.
The second indication is a Message warning when viewing
another page (Map, for example). The Message text is,
“Heavy Radar Echoes Beyond 60nm”. The Message warning
is cancelled when you acknowledge it (by pressing the
ACK
key), or when the alert is eliminated by the radar sensor.
