I know that landing lights should be turned on/off at FL10 depending if you are descending/ascending. Is that based on the barometric altitude or the above ground altitude (AGL) ?

Baro usually. But in the case of some high altitude airports ( Denver, Bogota, etc.) your best estimate of 10000 AGL will do. Better early than later when it comes to safety.

OK, thanks.

FL10 is technically 100,000 feet. FL's aren't used until you get up to 18,000 and above.

Surely 100,000 feet would be FL100

I don't know about the Real World 'technical' jargon, but I do know that in the Sim World of MSFS, FL10 means 10000 ft.

In Real World, too. Your're right. Of course.

Thanks Martin.

Hehe, those zeros... :o hock: :?
FL100 ~ 10,000 ft

FL10 (which would be altitude one thousand feet) does not exist, because it is below any possible transition altitude (anywhere all over the world).

See http://en.wikipedia.org/wiki/Flight_level for example.

Remember, we are talking MSFS. As I stated, in the Sim World of MSFS, FL10 MEANS 10000ft. Regardless of what you read or you exposed to in Real World training, we follow the rules in the game. It is a game by the way, I'm just following the rules as best I can and stay as current with Real World guidelines and adhere to to them as they apply to our Sim. It was a simple question with a simple answer. Anything else deduced from such is getting off topic.
