PRIMARY ALTIMETER.
- 1. ALTITUDE ADVISORY LIGHT (amber).
- The light will come on when the aircraft enters the advisory threshold
750 feet above or below the selected altitude. The light will extinguish
when coming less than 250 feet from selected altitude. If aircraft deviates
more than 250 feet from selected and previously acquired altitude, the light
will come on flashing in combination with an aural tone and a spoken word
"altitude".
- 2. BARO set knob.
- The knob is pressed and rotated to set the reference pressure as read in
the readout.
- 3. REFERENCE INDEX set knob.
- Used to set altitude reference index as desired. Before takeoff the
index is set to clean up altitude in case of engine failure, normally
departure airport pressure altitude + 800 feet. During approach and landing
he index is set to CAT I minima.
- 4. ALTITUDE REFERENCE index.
- Index is set by the reference index knob.
- 5. DIGITAL ALTITUDE read out.
- Indicates barometric altitude from -1 000 feet to 50 000 feet. The right
hand two digit drum rotates continuously and is divided in 20 feet increments.
The left hand drum is divided in 1 000 feet increments and the 10 000 feet
field is green when below 10 000 feet.
