Airbumps2501 Posted 9 hours ago Posted 9 hours ago Hi All, I've done four flights in the A340 now and on each occasion the take off calculator has given me the error "UNABLE TO FIND SAFE PERFORMANCE DATA". All takeoffs have been from major airports, EGLL, KCLT, KLAX and EDDM at moderate weights. In this instance, I'm AT KLCT trying to get it to give me take off performance for a flight to EDDM. Using the SimBrief take off calculator works fine - But the EFB one doesn't seem to work. Does anybody have it working or any suggestions?
