Barometric Pressure Setting (BARO)
Barometric pressure is adjusted with the right knob to provide a barometric-corrected
altitude on the display.
The barometric pressure value can be entered in either inches of mercury (IN) or
millibars (mB), as configured in the Main Menu GENERAL SETTINGS page.
The barometric pressure setting is retained over a power cycle of the equipment.
Altitude Alerts
Visual (and optional aural) altitude alerts are generated for level-off and deviation
conditions. A yellow, level-off alert illuminates next to the selected altitude numerical
field when the aircraft is within 15 seconds or 200 feet (whichever is greater) of the
selected altitude. When an optional aural alerter is installed, a 1 second tone is
provided.
After reaching the selected altitude if the aircraft altitude deviates by more than ±200
feet from the preselect value then a flashing yellow altitude deviation alert is generated,
accompanied by a one second tone from the optional aural alerter.

12.9.4 Vertical Speed Indicator (VSI)
Whenever the vertical speed exceeds +/- 100 fpm the vertical speed is indicated by a
rising/sinking white vertical tape and associated scale markers immediately to the right
of the compass rose. A numerical indication or current aircraft vertical speed is shown
directly above the tape. Rates of ±2000 feet per minute (FPM) are indicated by the tape
while the numerical value will display rates of up to ±9990 FPM. A triangle caps the tape
whenever rates exceed ±2000 FPM.
In the ARC compass mode only the digital vertical speed value is presented.
