At a certain point in the decline in property values, it no longer pays owners to maintain lifts, services and utilities (as on a British tower estate).
At a higher altitude less oxygen is available for their muscles, and the thin air makes it harder to maintain lift.
Forty seconds later, the pilots extended the flaps, the moveable panels on the rear edge of the wings that allow a plane to maintain lift as it slows.
The crew also could not reposition the left wing's slats, which are small panels that normally help maintain lift at the low speeds of takeoff and landing.
By providing much of the forward thrust, it allows the rotors to turn at a slower speed, sufficient only to maintain lift.
When air flow over the wings is not sufficient to maintain lift, one system is in place to warn pilots of an impending aerodynamic stall, Mr. Chealander explained, and a second will act if the pilots do not.
The crew, having earlier requested a descent to avoid haze, lowered the landing gear and then extended the flaps, the movable panels on the rear edge of the wings that allow a plane to maintain lift as it slows, according to the flight data recorder.
It can be seen that higher D/d causes high n which can imply low T due to small A. However, large D has to be selected to maintain lift force of the gas balloon.
To maintain lift, pilots have to find thermal pockets and surf wind patterns created by the geographic terrain. .
In the end, in order to maintain lift at higher forward speeds the craft had to be pitched to the end of its control capability.
