Glide is a flight trajectory where the spacecraft stays in the atmosphere for a sustained flight period of time. [1] In most examples, a skip reentry roughly doubles the range of suborbital spaceplanes and reentry vehicles over the purely ballistic trajectory. In others, a series of skips allows the range to be further extended.
Powered aircraft range is limited by the aviation fuel energy storage capacity (chemical or electrical) considering both weight and volume limits. [1] Unpowered aircraft range depends on factors such as cross-country speed and environmental conditions. The range can be seen as the cross-country ground speed multiplied by the maximum time in the ...
Emission patterns of the localizer and glide slope signals Glide slope station for runway 09R at Hannover Airport in Germany. In aviation, instrument landing system glide path, commonly referred to as a glide path (G/P) or glide slope (G/S), is "a system of vertical guidance embodied in the instrument landing system which indicates the vertical deviation of the aircraft from its optimum path ...
Localizer as component of an ILS (KMEZ runway 27, Mena, Arkansas) Emission patterns of the localizer and glide path signals. An instrument landing system localizer, or simply localizer (LOC, [1] or LLZ prior to 2007 [2]), is a system of horizontal guidance in the instrument landing system, which is used to guide aircraft along the axis of the runway.
Each type of helicopter has a specific airspeed at which a power-off glide is most efficient. The best airspeed is the one that combines the greatest glide range with the slowest rate of descent. The specific airspeed is different for each type of helicopter, yet certain factors (density altitude, wind) affect all configurations in the same manner.
The PAPI can be seen to the right (non-standard) side of the runway. The aircraft is slightly below the glideslope. A precision approach path indicator (PAPI) is a system of lights on the side of an airport runway threshold that provides visual descent guidance information during final approach.
The tangent defines the minimum glide angle, for maximum range. The peak of the curve indicates the minimum sink rate, for maximum endurance (time in the air). Without power, a gliding aircraft has only gravity to propel it. At a glide angle of θ, the weight has two components, W.cos θ at right angles to the flight line and W.sin θ parallel ...
A glider's glide ratio varies with airspeed, but there is a maximum value which is frequently quoted. Glide ratio usually varies little with vehicle loading; a heavier vehicle glides faster, but nearly maintains its glide ratio. [22] Glide ratio (or "finesse") is the cotangent of the downward angle, the glide angle (γ). Alternatively it is ...
