have flown the F100 for a few thousand hours! the early versions with the RR tay 620 engines are a bit under powered when at max TOW the RR tay 650 engines were alot better. the flight deck can be quite noisy due to the pilots sitting above the air conditioning packs, but i have to say the aircraft is a terrific design! not many swept wing jets you can take off clean (zero flap) and climb to cruising speed/ altitude without a config change.
the huge rear speed brake is wonderful, have done 320kts to a 12 mile final deployed the speed brake and been fully configured for landing at vref plus 10 flap 42 gear down by 1000' !!
the autoland system is fantastic! certified to cat 3b zero decision and 75 m viz with up to 25 kts x wind, autopilot is dis engaged at 60 kts!!very impressive and always lands on the centerline!! (more than i can do!)
a great fun to fly airplane let down by reliablility problems.
