How to Avoid Helicopter Dynamic Rollover

What is dynamic rollover?

Dynamic rollover sounds like a term that could be used by companies lottery. Every helicopter pilot is aware that the dynamic rollover can be a problem if off or landing of a helicopter.

Dynamic rollover occurs when a wheel or a skid on the airplane on the ground and acts as a pivot point attached to the helicopter role. It 'much more likely to take off, and if not handled properly, the helicopterrolled on its side and suffer serious injuries. This occurs from time to time experienced pilots, but much more likely to happen with a low-time pilots.

Have you ever tried to pull the door handle and the door refused to budge? Then, when you press the handle of the door opens and takes by surprise. He did not expect it to happen. The same can happen with a take-off. Smoothly increase the collective and one of the runners lifts the ground. They expect theanother runner to follow, but unfortunately 'caught something and refuses to move. Your natural reaction is to further increase the collective to release the helicopter land, but all you get is a quick introduction of a helicopter in the direction of non-slip. The dynamics of this role may be sufficient, the helicopter rolled over while holding down the collective hours. The inevitable happened and the helicopter rolled on its side and you suffer serious damage.

Thenatural reaction to the collective growth, in order to solve the problem is the wrong reaction, and you have to discipline the correct action, the lowering of the collective smoothly until both runners to make the field.

Results

The results of a dynamic rollover is usually very difficult. The helicopter was destroyed in the rule. The damage from a helicopter rolled over after a self-rotation is much less than the damage caused by the dynamic rollover. This is because, during aAuto-rotation of the blades are non-powered, and if it goes over, you will quickly come to rest. During take-off, but plan to use a lot of energy and the helicopter rolled out, will not, can occur quickly and rest a lot more damage.

Take-off

You can see that Take-off can cause a problem. Icy frozen ground and skates can be a real problem. Muddy or sticky, rocks, can lead all runners to capture the concrete in the joints and lead to dynamic rollover.It must be every time, but especially the first take-off will be taken.

Be sure to look ahead. Raise the collective smoothly, until you remember to have the light on the helicopter skids. From this point, you need the collective shift very slowly. The more we stand out, the slower the collective must be placed in service. Try a little ', "wiggle" by pressing the pedals easily. This will give you a hint, if both are free riders. If you are on a flat surface, a Skidprobably begins to rise before the others. It 'important at this stage, not the collective race. If you believe that the helicopter is rolling too far to ensure a flat lower the collective and both skates on the ground before returning to take off. If both the races (wheels) are not found on the floor, get the helicopter to a safe altitude to ensure that riders do not accidentally take on something.

When the helicopter is on the ground with the blades rotate ever,Your hand from the collective unless the collective down and locked up. There have been many cases in the collective movement of passengers, or collective until the helicopter was vibrating rolls.

Ensure that the aircraft is within its boundaries and balance to ensure that racing does not come out during cyclic normal takeoffs and landings, increasing the risk of tipping dynamic.
