I just re-read the article on the Vertical website regarding take offs with the tail rotor hydraulics turned off which is possible in the earlier B3’s, that article is also very critical of the complexity in the system & the functionality of the test sequence for pre-take off & for training. I’m sure it would not be difficult to have a spring loaded switch on the cyclic specifically for training, the functionality of this switch would only be activated by engaging a “ missile” type switch on the console. That way practicing for a hydraulic failure event the pilot could engage the switch which simulates the hydraulic failure, if at any stage during the training sequence things started to go pear shaped all you need to do is release the switch & hydraulics are restored. If you accidentally release the switch you get hydraulic function back, bugger, have to go around & start again.
This doesn’t help the “ light framed” people with man-handling the controls but it would save critical seconds when they’re needed the most.
Heli-ringer is right, follow the manual & all is good but a manual is an administrative control, engineering solutions are better. You can fly around at 60knots all day with the hydraulics off no problem, but get below translational lift speed & you’d need arms the size of Arnie’s legs to keep it under control.
