Gidday,
F-100s normally have and use their APU for all services on the ground. However some airports require you to use their ground power/aircon for noise and polution reasons apart from the ability to bill you for the service!!!
F-100 is rather nice, a Fokker-28 on steroids, good automatics, customers seem to like them, pull 100 pax, full fuel on a 3hr+ leg, bit restricted on landing weight on those sort of loads, ie about 12,000lbs from max T/O to get to the normal max ldg wt.
The door requirements make the Jumpseat a bit of a trial for longer sectors
If the engineers are up to speed they keep going and going, makes you wonder the politics of the cessation of Fokker as they and the F-70 are quite a good product IMHO.
Did 22yrs and 10,000hrs on the 28, just a little on the 100, now usually in the Sim for the 100, best "electronic likeness of life" you could ask for in semi-retirement.
