I can read the (A:Overspeed Warning, bool) as a 0 or 1, but not the (A:Stall Warning, bool). The only reference I've found for this variable is inside the 747-400 EICAS Display.xml. There it was used inside a string so I assume the variable is functional. Any ideas?Glenn

Hi Glenn,Sounds strange. I think you should chreck your complete code again because the variable (A:Stall Warning,bool) works without any problems.Best RegardsMatthias

Matthias, Thanks for the response. Turns out it was the aircraft I was checking the variable in, the King Air. The darn thing doesn't stall. With full up elevator and no power, it mushes to the ground more or less horizontally at about 90 knots, above stall speed. Sheezz!Glenn
