Hi y`all, new at pprune. Reading your threads for quite a long time now and now feel to comment things myself.
Concerning flaps at the F100, I most of the time use 0 flaps even at MTOW. Seldomly do I use flaps 8, never flaps 15. Flaps 8 are needed mostly for 2nd segments and always used after de-icing. Performance calculation differ though, depending on balance or unbalanced TO calculations.
Landing flaps are mostly 42, but 25 flaps should be trained even during line operation.
25 flps may be needed to land in Sarajevo at minimum to be able meet the GA climb requirements.
Bye
