Indicated airspeed at threshold, which is usually equal to the stall speed V S0 multiplied by 1. Maximum operating limit speed. They are typically defined with constraints such as weight, configuration, or phases of flight. Fourth Edition, Military jet aircraft take-off from aircraft carrier with afterburner at 50 ft dB. In modern gliders, V ms and V jet plane explanation threshold have evolved to jet plane explanation threshold same value. For explanatioh aircraft the propulsive efficiency essentially energy efficiency is highest when the engine emits an exhaust jet at a speed that is the same as, or nearly the same as, the vehicle velocity.

Unserviceability of any of the devices which affect the aircraft braking brakes, anti-skid, reverse thrust, lift-dump, etc. Note: landing performance calculations normally assume that reverse thrust is not available. Major unserviceability e. The complexity of the task even with Autoland is such that even in ideal conditions, a perfect landing is virtually impossible, while any deviation from the ideal adds to the actual landing distance.

The maximum landing mass and the landing speed depend on the runway braking conditions. If these have been inaccurately reported or if the runway is wet or contaminated when its condition was reported as being dry, the landing distance achieved will be increased. The presence of standing water, snow, slush or ice on the Jet Plane Explanation Zip runway has a particularly serious effect on landing performance and if it cannot be cleared, it must be reported as accurately as possible.

Special techniques must be used by pilots when landing on contaminated runways. Steel mill, auto horn at 1 meter. Turbo-fan aircraft at takeoff power at ft dB.

Newspaper press 97 dB. The most common V-speeds are often defined by a particular government's aviation regulations. The descriptions below are for use by pilots. These V-speeds are defined by regulations. They are typically defined with constraints such as weight, configuration, or phases of flight. Some of these constraints have been omitted to simplify the description.

In discussions of the takeoff performance of military aircraft, the term V ref stands for refusal speed. Refusal speed is the maximum speed during takeoff from which the air vehicle can stop within the available remaining runway length for a specified altitude, weight, and configuration. Some of these V-speeds are specific to particular types of aircraft and are not defined by regulations.

Whenever a limiting speed is expressed by a Mach number , it is expressed relative to the speed of sound, e. V 1 is the critical engine failure recognition speed or takeoff decision speed. It is the speed above which the takeoff will continue even if an engine fails or another problem occurs, such as a blown tire.

Aborting a takeoff after V 1 is strongly discouraged because the aircraft will by definition not be able to stop before the end of the runway, thus suffering a runway overrun. From Wikipedia, the free encyclopedia.
