403 - UVID-15 altimeter power
404 - AGR standby ADI power
405 - Clears BKK error signal and flags on the ADI
406 - BKK vertical gyro power
407 - ABSU/SAU power (autopilot and flight director)

419 - Static pressure SVS system power
421, 422 - KURS-MP nav radios power, left and right
423 - RSBN nav system power
424 - RSBN “Ident” mode switch. Since this mode is hardly ever to be implemented in FG, in the model this switch toggles RSBN to the VOR mode
425, 426 - RV-5M Radio altimeter power. Only the captain’s radio altimeter works in the model
427, 428 - COM radios power
429, 430 - ADF radios power
431, 432 - CB for roll correction of the lateral gyro. Since the simulator does not implement gyro drift, these switches are not utilized. Perhaps one day the gyro drift will be implemented…
433 - Doppler drift and ground speed measurement system (DISS) power
434 - “land-sea” Doppler switch
435 - the “Diss-SVS-check” whether the NVU will be driven by the Doppler system or the static air pressure system alone. When NVU is on SVS uncoupled from the DISS you will need to compute and enter the wind drift yourself.

If RSBN works in compatibility mode with VOR, the left knob sets megahertz, right - kilohertz. In this mode, there is a tooltip for the frequency. The “RSBN-VOR” is possible only in the model, in terms of realism the use of this mode is not recommended
439 - Transponder. Implemented since ver.3.0. Work under FG ver.2.10 and newest. It support skawk mode A, C, Standby mode (selector to B) and Ground mode (selector to D).
440, 441 - COM radios. There are hotspots for fequencies. Right handle control sound volume.
442, 443 - ADF radios. The switch on the top selects the “active-standby” frequency, the selected frequency is highlighted with a green lamp on top. The left ADF is 1, right one is 2. There are hotspots for control sound.
444 - Pitot heat switch. As far as I know, the effects of pitot icing are not modeled in FG
445, 446 - KURS-MP nav radio. The indicator on the left switches the bearing (not the indicator on the HSI!), the right controls the frequency. Hotspots are availaible at the top and at the bottom of each digit. There are hotspots for control sound.
