engine-exhaust trail — A cloud that trails an aircraft and is formed by the ejected water from the exhaust of the aircraft engines. It mixes with and saturates, or slightly supersaturates, the air in the wake of the aircraft. The duration of the trails is dependent on… … Aviation dictionary
vapor trails — A long trail of visible moisture left by an aircraft as it flies at high altitude through very cold air. The trails are formed by the condensation of water vapor in the exhaust gases leaving the engine. They appear at a slight distance behind… … Aviation dictionary
contrails — A long trail of visible moisture left by an airplane as it flies at a high altitude through very cold air. The trails are formed by the condensation of water vapor in the exhaust gases leaving the engine. They appear at a slight distance behind… … Aviation dictionary
MINTRA/mintra level — The flight level below which exhaust trails will positively not form. They may or may not form above the MINTRA level. This flight level is obtained from a tephigram drawn by the meteorologist. DRYTRA is the level above which exhaust trails will… … Aviation dictionary
aerodynamic trail — A condensation trail formed by adiabatic cooling to saturation (or slightly supersaturation) of air passing over the surfaces of high speed aircraft. Aerodynamic trails form off the tips of wings, propellers, and other points of maximum pressure… … Aviation dictionary
Kolchuga passive sensor — The Kolchuga passive sensor is an ESM system developed in Ukraine. Its detection range is limited by line of sight but may be up to 800 km (500 miles) for very high altitude, very powerful emitters. Frequently referred to as Kolchuga Radar , the… … Wikipedia
