Ouch :(
Very lucky to walk away from this one ! |
Is t that something you check during the preflight?
|
You check your pedals connection in the underfloor part??? :ok:
|
My mistake, from memory thought it was visible.

Have you SEEN those videos of mustering operations? There is no operation like it. But, the factory don’t seem to have tested for it.

could one still control the tail ....
1/ with one foot alternatively in front and behind the only left pedal .. mabe not 2/ or by frictioning your foot below that one pedal ... could work? 3/ by moving your feet to the copilot side ... that I got to see! |
Slide completely to the left side. Even if the left side of the cyclic isn't there, you can still fly with the right hand on the centre prong. It might be a bit of an exercise in the air, but chopper pilots are super-human, aren't they?
Coping with the cg change is something else, though. Main fuel on left side. |
A victim of the old 4000 psi of pressure on one pedal, 4001 psi on the direction of turn...........

Hey AC.
I wonder if it was result of a Hufnagel sequence maneuver? LOL |
T-Bags, Oh, I wish I could have photographed your eyes when you saw that one happen! Looked like VASIS, but both red!

I teach students who are bracing both feet against the pedals to place their right foot on the floor. Torque in the 22 is taking the nose right, so it’s actually very easy to fly left foot only. Apply left foot/pedal, nose yaws left. Bring left foot/pedal back and Nose yaws right.
Teaches the students that they are being far too heavy with their feet. So in the case of this chopper, I’d say no problem getting it down safely. Huey |

Ah, I missed that bit. Yes jammed pedals would make things far more difficult.

I once took control from a student who was messing up a steep turn (not in a Robbie) and couldn't move the pedals as he had tensed up and was pushing very hard with both feet - I had to shout at him to take his feet off the pedals so I could recover to S and L flight.

OK I got an idea for people with long legs

Yep, that lingering outback bull dust gets into everything.
Switching sides will only confirm that. |
