🚁AFCS System (Autopilot)

AFCS IS NOT FUNCTIONAL ON THE CURRENT BUILD - A Custom, Functional Two-Degree of Freedom AFCS (Autopilot) System has been developed for the CH47D, and will be added in an upcoming update, shortly after the release of SU15.

A minimum 2% Deadzone (In some cases up to 5-8% on old or inaccurate hardware) is required for AFCS to function correctly. Not enough deadzone will result in the input controllers and the system inputs conflicting with each other, leading to erratic or unexpected behavior.

AFCS Panel

1. HDG SELECT: Upon pressing and engaging, the aircraft will follow the Selected Heading on the Pilot Side HSI. System Select must be set to any option but OFF.

2. BARO ALT HOLD: Upon pressing and engaging, the aircraft will mantain the current Barometric altitude. System Select must be set to any option but OFF.

3. RAD ALT HOLD: Upon pressing and engaging, the aircraft will mantain the current Radio altitude. Will not engage above 1,000ft above ground. System Select must be set to any option but OFF.

4. System Select: Selects the AFCS System the aircraft will use. Under normal conditions, BOTH will be selected for redundancy. HDG/BARO/RAD won´t engage unless the selector is at any position other than OFF.

6. Cyclic Trim AFT

7. Cyclic Trim AUTO/MANUAL Selector

The CH47D does not have any sort of Speed Hold, nor it has Vertical Speed modes, Autohover, etc.

Speed can be controlled by a combination of ALT Holds and Longitudinal Cyclic Trimming. Trimming the aircraft down while holding the altitude will result in a forward acceleration; similarly trimming the aircraft up will result in a forward desceleration.

To perform altitude changes, the pilot input is required.
