  visibility restrictions; but the hazards are multiplied when associated with the other thunderstorm hazards of turbulence, hail, and lightning. Effect on Altimeters Pressure usually falls rapidly with the approach of a thunderstorm, rises sharply with the onset of the first ... pilot does not receive a corrected altimeter setting, the altimeter may be more than 100 feet in error. Lightning A lightning strike can puncture the skin of an aircraft and damage communications and electronic navigational equipment. Although lightning has been…

  epoxy resin, can be used with auto gas, as well as 100 octane aviation gas (avgas) and jet fuel. Lightning Strike Protection Lightning strike protection is an important consideration in aircraft design. When an aircraft is hit by lightning ... structure. Whether flying a light general aviation (GA) aircraft or a large airliner, the basic principle of lightning strike protection is the same. For any size aircraft, the energy from the strike must be spread over a large surface area…

  Phenomena beyond 10 statute miles will be shown as distant, “DSNT.” Distances are in statute miles except for automated lightning remarks which are in nautical miles. Movement of clouds or weather will be indicated by the direction toward which ... WSHFT (FROPA). (6) TWR VIS or SFC VIS. (7) VRB VIS. (8) Sector VIS. (9) VIS @ 2nd Site. (10) Lightning.

  Then the lower altitudes may be characterized by strong out flowing winds and severe turbulence. e. The probability of lightning strikes occurring to aircraft is greatest when operating at altitudes where temperatures are between minus 5 degrees Celsius and plus ... degrees Celsius. Lightning can strike aircraft flying in the clear in the vicinity of a thunderstorm. f. METAR reports do not include a descriptor for severe thunderstorms. However, by understanding severe thunderstorm criteria, i.e., 50 knot winds or 3/4 inch…

Lightning detection is a second reliable means for identifying potentially dangerous weather. Lightning gives off its own electromagnetic signal. The azimuth ... lightning strike can be calculated by a receiver using a loop type antenna such as that used in ADF. [Figure 11-144] Some lightning detectors make use of the ADF antenna. The range of the lightning strike is closely associated…
