L-1011 Trainer Installation: Flight Director Integration Tests

L-1011 Flight Director Integration Tests

The ADIs in the L-1011 simulator incorporate Flight Director (FD) bars for Pitch, Roll and Yaw. Today I worked on moving Flight Director information from X-Plane to the ADIs. To do so, I am using ARNIC 429 Label 170, 171 and 172. The Flight Director bus is a slow speed bus and FD information is passed to the ADI at 12.5Kbps. For the first few tests tonight I focused on the roll and pitch data. X-Plane actually does not have Flight Director data for guided yaw, however, that information can be derived from a number of other X-Plane data points.

The video below is a short demo of a Flight Director guided roll to the left to heading 225 and then we see a flight director guided roll-out at the target heading. Watch the HSI and the ADI in particular:

p.s. Ignore the erratic Localizer indicator on the ADI, it's only getting test data.
