Subject: AB9 / DCS MiG-29A – realistic ARU control loading and AoA stick-pusher support
Hello MOZA Flight Support,
I am using a MOZA AB9 FFB base with DCS World, primarily with the full-fidelity MiG-29A module.
My goal is to reproduce the real MiG-29A control forces as accurately as possible. I have original MiG-29 flight manuals which describe the aircraft's longitudinal control loading system, ARU (automatic control loading/control ratio system), trim system and the critical-AoA stick-pusher system.
I would like to know whether the current MOZA Cockpit software/MCLS can reproduce the following functions, or whether support for them is planned.
1. MiG-29 ARU – IAS and altitude dependent stick forces
According to the original MiG-29 flight manual, the ARU changes both the longitudinal control ratio and the stick loading ratio according to airspeed and altitude. It receives information corresponding to static and dynamic pressure.
At low altitude, the manual describes approximately the following schedule:
up to 400 km/h IAS: minimum stick loading / maximum stabilizer authority
400–870 km/h IAS: progressively increasing stick loading
870–1200 km/h IAS: maximum stick loading
1200–1500 km/h IAS: progressively decreasing stick loading again
at 1500 km/h IAS: minimum stick loading again
The difference between the two extreme ARU control-loading ratios is approximately 2.22:1.
The problem I currently see in MOZA Cockpit is that “Dynamic Stick Pressure” appears to use True Airspeed (TAS). The real MiG-29 ARU does not simply follow TAS; its behaviour depends on indicated/dynamic-pressure-related airspeed and altitude.
Is there currently a way for an aircraft profile to use IAS/dynamic pressure + altitude instead of TAS for the stick-pressure curve?
2. ARU movement of the force-neutral stick position
The MiG-29 manual also states that movement of the ARU from its take-off/landing position to the fully retracted position causes approximately 26 mm displacement of the force-free control-stick position.
Can MOZA Cockpit dynamically change the physical FFB centre/neutral position according to telemetry, independently of normal pilot trim?
I already use “Apply Trim Effect”, and trim correctly moves the physical AB9 stick. Therefore, the hardware is obviously capable of moving the physical force-neutral position. What I am looking for is a second, telemetry-controlled neutral-position offset for the ARU.
3. Critical-AoA stick pusher (SOS / СOС)
This is particularly important for the MiG-29.
According to the original manual, when critical angle of attack is reached, the system actively pushes the control stick forward (“away from the pilot”) with a force of approximately 17 kgf. The pilot can override this force.
DCS appears to simulate this behaviour on the virtual MiG-29 control stick, but my physical AB9 does not reproduce the forward stick movement/force.
At the moment I can only approximate the warning using MOZA AoA/stall buffet or shaker effects. This provides a warning, but it is fundamentally different from the real aircraft's directional stick-pusher force.
Is there a way in the current MOZA software/MCLS to command a directional FFB force or forward centre-position movement triggered by DCS telemetry or DirectInput FFB?
If not, is support for this type of aircraft-specific stick-pusher planned?
4. Flight-simulator SDK / custom control-loading model
If the above functions cannot currently be configured in Cockpit, I would also be very interested in an SDK/API that allows direct control of the AB9 FFB motors.
Ideally, I would like to implement the MiG-29 control-loading laws directly from the original flight manual using DCS telemetry:
DCS IAS + altitude → ARU position → control-loading ratio + neutral-position offset
and
DCS AoA / aircraft state → SOS activation → directional forward stick force
This would also be useful for other aircraft with mechanical/hydromechanical control-loading systems.
I am not asking for generic stronger FFB or additional vibration effects. My objective is to reproduce the actual control-loading behaviour described in the real aircraft documentation.
If useful, I can provide the relevant pages/figures from the original MiG-29 flight manual, including the ARU diagrams and control-stick force diagrams.
Could you please tell me which of these functions are currently possible with the AB9 and MOZA Cockpit/MCLS, and which may require future software or SDK support?
