The HSI is now stable, but does not agree with the other compasses. Is there a gyro alignment procedure that I need to learn?

It's only .0016V too high, probably safe enough ;-) It's on a 115V AC bus which has no alternative AC power available (no standby inverter feed) so requires a generator to be online, which in turn requires sufficient engine RPM. It shouldn't require full power - I think it's at least 60% on one engine - but I'd have to do some digging find the Pilot's Notes and check that value is right. > Check the computation for /systems/electrical/outputs/DG in > Aircraft/Lightning/Systems/lightning-electrical.nas.

Thanks for investigating the issue... the Lightning electrical system almost certainly has logic bugs and omissions (I don't much enjoy working on electrics in real life and I seem to remember wanting to rewrite it at some point which never arrived.) I'd be very happy to supply the relevant electrical diagrams if anyone actually enjoys coding this kind of thing :-) AJ -- ------------------------------------------------------------------------------ Don't let slow site performance ruin your business.
