How to Avoid Dynamic Rollover in Helicopters
Dynamic rollover sounds like a phrase that could be used by the lottery companies. Each helicopter pilot is aware that dynamic rollover can be a problem when taking-off or landing a helicopter. Dynamic rollover is caused when a wheel or a skid on the helicopter becomes attached to the ground and acts as a pivot point that the helicopter can roll around. It is much more likely to happen on take-off, and if it is not handled correctly, the helicopter will roll over onto its side and take substantial damage. This does occasionally occur to experienced pilots but is much more likely to happen with low time pilots.How to Fly Basic Autorotations in Helicopters
In the course of your helicopter training, you will have to learn how to glide the helicopter in unpowered flight. All helicopters can glide. We call it "autorotation". We practice autorotations so much during training that they become a part of normal helicopter flight. But do not think that autorotations are common in real life. Engine failures are extremely rare and tail rotor failures are even rarer. So how do we do a basic autorotation?Visual Cues When Hovering Helicopters
The next time you see a helicopter take-off and lift into the hover and it takes off and comes to a nice steady hover; ask yourself how the pilot is keeping everything so steady. The main reason is lots of practice. Good co-ordination and muscle memory make things easier but with the practice he/she has also developed a scan outside that allows him to see any movements of the helicopter.
