1.3.17. DRIFT C/O switch
The DRIFT C/O switch is a three-position switch with a momentary position to WARN RESET.
Upper and middle positions manage the DRIFT of the flight path marker according to winds. The
centre position, labelled NORM takes winds into account and lets the FPM drift to the side according
to crosswinds, giving you a visual cue of beta angle (sideslip crabbing into the wind).
In the NORM position the FPM indicates where in 3D space the aircraft will fly towards with the current
flight conditions and no additional control inputs. In other words if you hold what you have on the
controls the FPM will show you where the jet will ultimately end up.
This is particularly useful for landing because it lets you picture the wind visually so you can
compensate automatically.
On the other hand it may be an annoyance at high altitude with strong winds (which may throw the
FPM off the edges of the HUD) and the upper position labelled DRIFT C/O maintains the FPM in the
centre of the HUD regardless of winds. The switch should be placed to NORM before landing.
The lower momentary position is labelled WARN RESET and is used to reset the HUD WARN
message.
1.3.18. The ICP Thumbwheels
The top left is labelled
SYM and used for HUD brightness. The wheel has an ON/OFF switch at the
beginning of its travel, which is where the HUD is powered up.
The one
labelled DEPR RET (top right) lets the pilot manage the backup bombing mode.
The brightness (
BRT ) wheel (bottom left) controls FLIR brightness on the HUD. Use this wheel to
display the FLIR image on the HUD. Its effect will only be noticed when the FLIR is operational.
The bottom right wheel (
CONT ) is not implemented at this time.
It is possible to control the implemented wheels with the mouse, keystrokes or an analogue axis.
