zero-zero ejection seat is designed to safely extract upward and land its occupant from a grounded stationary position (i.e., zero altitude and zero airspeed)...

elevation or altitude) in reference to a vertical datum based on a historic mean sea level. In geodesy, it is formalized as orthometric height. The zero level...

Altitude is a distance measurement, usually in the vertical or "up" direction, between a reference datum and a point or object. The exact definition and...

[citation needed] A zero-zero ejection seat is provided for the pilot, permitting safe ejection in an emergency even at zero altitude and zero speed.[citation...

crew member in a wide range of speeds and altitudes of aircraft flight, from zero altitude, zero speed (zero-zero) upwards, and can be used in conjunction...

quickly back up to altitude. A short burst of fire from heavy machine guns or cannon was often enough to bring down the fragile Zero. These tactics were...

burns to two personnel at ground zero who were not wearing their safety goggles. The Soviets detonated four high-altitude tests in 1961 and three in 1962...

Zero 2 Infinity (0II∞, sometimes rendered as Zero2Infinity) is a private Spanish company developing high-altitude balloons intended to provide access...

rocket-assisted ejection seats which are zero-zero capable, meaning they can be used safely at zero altitude and zero speed. Although JL-8 is designed to have...

astronomy. High-altitude balloons have been considered for use in telecommunications and space tourism. Private companies such as Zero 2 Infinity, Space...

base of the altitude. The intersection of the extended base and the altitude is called the foot of the altitude. The length of the altitude, often simply...

zero-elevation surface had to be selected as a reference level; this is called the areoid of Mars, analogous to the terrestrial geoid. Zero altitude was...

at high altitude, either on land, in water, or while flying. Decreased oxygen availability and decreased temperature make life at such altitudes challenging...

atmospheric pressure. Altitude decompression is hypobaric decompression which is the natural consequence of unprotected elevation to altitude, while other forms...

aircrew sat under separate clamshell canopies on Weber ES-7J zero-zero (zero altitude, zero speed) ejection seats, built by Daiseru. The seats featured...

Martin-Baker GRU-7A rocket-propelled ejection seats, rated from zero altitude and zero airspeed up to 450 knots. The canopy is spacious, and fitted with...

aircraft's zero-lift drag force to its size, speed, and flying altitude. Mathematically, zero-lift drag coefficient is defined as C D , 0 = C D − C D , i...

sit on UPC/Stencel 10B zero-zero ejection seats, meaning that they are able to eject from a stationary aircraft at zero altitude. For the AV-8B, McDonnell...
