The definition of steady flight also allows for other maneuvers that are steady only instantaneously if the control inputs are held constant. These include the steady roll, where there is a constant and non-zero roll rate, and the steady pull up, where there is a constant but non-zero pitch rate.
Roll, pitch and yaw refer to rotations about the respective axes starting from a defined steady flight equilibrium state. The equilibrium roll angle is known as wings level or zero bank angle. The most common aeronautical convention defines roll as acting about the longitudinal axis, positive with the starboard (right) wing down.
Most aircraft trimmed for straight-and-level flight, if flown stick-fixed, will eventually develop a tightening spiral-dive. [2] If a spiral dive is entered unintentionally, the result can be fatal. A spiral dive is not a spin; it starts, not with a stall or from torque, but with a random perturbation, increasing roll and airspeed.
Steady initial climb speed. The all engines operating take-off climb speed used to the point where acceleration to flap retraction speed is initiated. Should be attained by a gross height of 400 ft (120 m). [10] V A: Design maneuvering speed. This is the speed above which it is unwise to make full application of any single flight control (or ...
After the flight, data were transcribed from the records and the results were correlated with pilot opinion. This approach would be considered routine today, but it was a notable original contribution by Gilruth that took advantage of the flight recording instruments already available at Langley and the variety of airplanes available for tests ...
DALLAS (AP) — Goodbye, cattle call. Southwest Airlines said Thursday that it plans to drop the open-boarding system it has used for more than 50 years and will start assigning passengers to ...
Simon Wu, a flight attendant for Cathay Pacific for six years, told Yahoo Life that a humidifier is a must after a long flight. "I absolutely need a humidifier for my skin after a long plane ride ...
Airport check-in is the process whereby an airline approves airplane passengers to board an airplane for a flight. Airlines typically use service counters found at airports for this process, and the check-in is normally handled by an airline itself or a handling agent working on behalf of an airline.
