No, i have a slight flicker on my foot where i can push it down at the ankle and its quite strong.
I wear a splint to keep my foot level as i would trip over it all the time otherwise, with this and the little flicker i have, i can operate the rudders fine. I can also operate the footbrakes but i choose to use the handbrake on the aircraft as its a bit safer. I can only use the handbrake on Piper made aircraft as these are like a car handbrake, on a variable type thing. Cessnas are a parking brake and i would lock the wheels up if i use the handbrake on there!
I prefer flying piper aircraft anyway to be honest.
Its possible for a hand rudder to be installed for people who cannot use their legs at all but its next to useless on the ground for steering.
I'd love to fly business jets one day but i dont think i'll get that far due to the hours required and the expense of getting the appropriate ratings. I.e commercial license, probably 1000-2000 hours, full instrument rating, multi engine jet rating, type rating on the aircraft you are wanting to fly, i.e a cessna citation. all in all minus the hours, your looking about £40k. its well paid though and worth it. Most airline pilots have been an instructor at some stage in their lives simply to gain the hours needed to unfreeze their ATPL license. (1500 hours, of which 500 must be on multi engine aircraft, jet or piston)
I'm currently on 57 hours, of which 20 odd are pilot in command. I need another 130 before i can start a commercial. Its an expensive and long winded thing!
