Is there any plan to add low altitude warning (audible/visual) in conjunction with the rad alt bug setting. 

We'd need someone to test and debug for that to be enabled. In theory (meaning defined in the modeldef), there are multiple flags coded for the RadAlt, but they are non functional in that they don't display when the modeldef commands them to. I'm the last remaining core developer, and have a PhD to complete plus an 8 month old rugrat who gets more mobile and inquisitive every week. The coding is trivial, but debugging/fixing the model is just not within my capacity.

Ok, thanks for the reply we are all busy, great work very much appreciated by me and no doubt all F14 drivers.
