MINIMUMS
A Minimum Altitude Alert can be set for approaches or related
reminders. The Minimums (MINS) Alert feature can be turned
on or off in the User Options Menu. When on, the Minimum
Value can be set by pressing the Control Knob until the MINS
annunciator turns magenta.
Once the MINS feature is active, turning the Control Knob left
or right will change the minimum value. Once set, the MINS
alert will activate when the aircraft descends past the set value
after being above it. When activated, the border around the
main altitude value (the ‘counter drum window’) will turn amber, along with the MINS numeric
value. The alert will stay active until ascending 50 units above the minimum value or until the
unit is power cycled.
VERTICAL SPEED
Vertical Speed can be displayed in two ways. As an analog
and digital vertical speed indicator (VSI) or as a dynamic
vertical trend line. Both the VSI and the Trend features can be
turned on or off independently under the VSI option in the User
Options Menu (VSI/TREND/BOTH/OFF). When on, neither
feature has any further user options.
The VSI feature provides an analog scale from -2000 to +4000
feet per minute (or -10 to +20 meters per second) and a digital
readout of the vertical speed up to ±9000 feet per minute (or
equivalent meters per second). The VSI units are determined by the configured altitude units
(feet or meters).
The vertical trend line is representative of a 6-second trend. The end of the magenta arc
predicts the aircraft’s altitude in six seconds given the current rate of climb or descent.
