airspeed

the speed of an aircraft relative to the air in which it moves

The speed of an airborne object relative to the atmosphere; in a calm atmosphere, airspeed equals ground speed.

In flight, airspeed (or Mach number) tradeoffs occur quickly enough to be considered instantaneous, and so climbs or dives along the energy level curves take little or no time with no losses (Kimberlin 2003; Lan, Roskam 1980).
Imaginary values and negative values are neglected since solutions containing these numbers were found not to be reasonable airspeed values.
The assumption that weight, drag and thrust are constant is made in the model defined for a small change in airspeed and altitude.
S], target airspeed in ft/s and ktas, the plot for altitude versus airspeed, and a stop button.
Specific excess power values computed from the conventional method in the flight simulator were inputted into the display under the same conditions of thrust, drag, weight and density to verify the accuracy of the airspeed computed by the technique.
The test revealed that, as the airspeed increases, it becomes difficult to hold the [P.
The use of the display in flying an optimal flight path proved difficult to fly since the pilot had to combine monitoring the target airspeed and specific excess power and also input a next [P.
When compared with prop approaches, the jets had almost imperceptible variations in approach attitude that could mean significant airspeed changes.
With the airspeed at the optimum AOA the aircraft will be at the optimum speed for its configuration.
If he took this logic to the extreme, the next course of action might mean a radical dive to pick up airspeed so we could pop up over the trees.
I said staying in the pattern would work fine--just keep it close to the runway and build up the airspeed.
A test pilot noted that "the boat became unstable and began yawing left and right at 70 KIAS" and that the "Maximum airspeed to be flown with the boat be seventy KIAS.
