Yes. It's one of the pilot's duties as part of the pre-start checklist ;-). Also something which needs to be done every 10-15 minutes when in flight, since the indication continuously drifts away. See here: http://www.pilotfriend.com/training/flight_training/fxd_wing/di.htm When the sim starts (or is reset), the initial indication should be aligned with the compass though. However, when the gyro isn't powered, the indication will be wrong as soon as the aircraft turns (offset). The HSI has a knob to adjust the indicator (see C172 cockpit), but it seems to missing in the Lightning. cheers, Thorsten ------------------------------------------------------------------------------ Don't let slow site performance ruin your business.
