1.2.3.10 ALTIMETER
The altimeter gives altitude in feet. The needle reads from zero to one
thousand feet on the outer scale and the large instrument window gives
altitude rounded to the nearest hundred feet. To derive the current altitude,
use the drum number and needle in combination.
For the example shown left, the drum reads 2500 feet tending to 2600 feet
and the needle reads 540 feet, so in combination they show the present
aircraft altitude as 2540 feet on QNH 3059 in Hg.
The smaller window on the right allows the pilot to input the local altimeter setting in millibars
(HectoPascal) or in inches of mercury depending on the options set in
Falcon BMS.cfg
to compensate
the instrument for the current atmospheric conditions.
The pressure is changed through the altimeter knob on the bottom left of the instrument.
The instrument is flagged PNEU when it receives only pneumatic pressure and no electrical power. In
this case the instrument behaves as a standard pressure altimeter.

1.2.3.11 AOA
The AOA indicator, located on the instrument panel, displays actual AOA in degrees.
The indicator has a vertically moving tape display indicating an operating range of -32° to
approxi32°.
The tape is colour coded from 9° to 17° to coincide with the colour coded symbols on the
AOA indexer.
The instrument is flagged OFF when there is no power available.
1.2.3.12 ADI
The ADI (Attitude Direction Indicator) is the main attitude flight instrument and
gives ownship attitude along pitch, roll and yaw axis supplied by the EGI/INS.
The F-16 ADI is mainly used for IFR flying and also features an ILS localiser
and glideslope when the ILS modes are activated.
The knob on the bottom right of the instrument is not implemented in Falcon
BMS due to the fact that it is used in reality to centre the instrument along the
fixed horizontal reference (according to the seating position of the pilot).
The ADI also has 4 flags, one in each corner of the instrument: OFF, LOC, GS and AUX.
The red OFF flag is displayed when the instrument does not receive power or the INS has failed.
The red LOC flag is displayed when the LOCaliser needle is unreliable.
The red GS flag is displayed when the Glide Slope needle is unreliable.
The yellow AUX flag is displayed while the heading value of the INS is not reliable. During ramp starts
the AUX flag remains displayed until status 90, 60 seconds into the initial INS alignment. When the
heading value of the INS becomes reliable the flag disappears. In BMS that is your cue for a short
ramp start; as long as the GPS switch is on, the INS will remain fully reliable.
