g-command system is not correct for the FLCS version we had


Recommended Posts

Just a minor bug in the CAT I Limiter. The blended AOA feedback bias used in the g-command system is not correct for the FLCS version we had.

According to Figure 3.1 Longitudinal Control Block Diagram from the DTIC paper 'F-16 Simulator for Man-in-the-Loop Testing of Aircraft Control Systems (SIMTACS)' (https://apps.dtic.mil/sti/citations/ADA189675), the AOA bias used for an initial g-command reduction should be 15.8, but not 15.0 as currently is in DCS. This results in a lower AOA limit than expected.

The figure is also backed up by the publicly available FLCS flashcard (https://quizlet.com/309832047/flcs-flash-cards/), which states that the G command system decreases available G when AOA > 15.8 (CAT I).

The current 15.0 bias is seems to be used by a very old version of FLCS.

16CM g-command should not be reduced until 15.8 AOA.trk
