How planes manage to hover in the air

(ORDO NEWS) — One of the most spectacular tricks of 3D model aircraft flying is called “hovering” (hovering). Most often it is performed on models with a pulling propeller, and we decided to make a small selection of hovering videos on jet models.

The purpose of hovering is to have the aircraft hover vertically, hovering above the ground like a helicopter. The aircraft should be as close to the ground as possible and as stationary as possible.

It just seems that, since the plane is hovering still, the pilot can relax and let go of the handles. In fact, hovering involves constant independent work by all controls.

First, the pilot must counteract the propeller torque with the ailerons, otherwise the aircraft will instantly spin in the opposite direction.

The ailerons work by blowing with a propeller and deviate almost completely, the reactive moment is very large.

Secondly, the pilot must constantly maintain altitude so as not to drop the plane and prevent it from flying upwards. Finally, the pilot must constantly correct for the slightest fluctuations in the air, even the lightest breeze.

In the computer simulator there is a special simulator for practicing hovering. It allows you to entrust the control of some axes to the machine, concentrating separately on thrust, on the ailerons or on the rudders and elevators.

The pilot gradually masters the control of individual planes, and then connects everything together. Here is a classic hovering on a propeller plane:

In the field, they try to perform the figure at a high altitude, so that in case of failure, they will catch the plane and take it away from the ground. With experience, the pilot descends lower and lower, gradually depriving himself of the right to make a mistake.

Interestingly, it is easier to perform the maneuver at a low altitude: when the aircraft is close to the pilot, it is easier for him to visually track the vibrations. The larger and heavier the model, the more stable it floats in the air.
