updrafts and down-drafts within and around thunderstorms.<\/li>\n<li>As air is drawn into a thunderstorm, strong updrafts may be encountered in clear air up to <strong>10\u201320 km<\/strong> around the storm and as far as <strong>25\u201330 km<\/strong> downwind.<\/li>\n<li>Severe turbulence can occur inside <strong>Cumulonimbus (Cb)<\/strong> clouds as well as between adjacent Cb clouds.<\/li>\n<li>Turbulence may also extend several thousand feet above and below the cloud.<\/li>\n<li>If turbulence exceeds the aircraft&#8217;s gust load limits, it may result in loss of control,

src=\"https:\/\/ibexaviation.com\/page-show\/aviation-meteorology\/m19-thunderstorm-hazards-3.jpg\" alt=\"\" loading=\"lazy\"\/><\/p>\n<ul>\n<li>Static electricity develops inside Cumulonimbus clouds due to the continuous movement of water droplets and ice particles.<\/li>\n<li>Lightning is most likely to occur when the ambient temperature is between <strong>+10\u00b0C and \u201310\u00b0C<\/strong>.<\/li>\n<li>Lightning strikes can puncture the aircraft skin and interfere with navigation and communication systems.<\/li>\n<li>Possible effects include a burning smell, loud explosive noise, temporary blindness or flash blindness, and inaccurate navigation indications.<\/li>\n<\/ul>\n<h3>Air Pockets, Gusts and Squalls<\/h3>\n<p>  <img decoding=\"async\" src=\"https:\/\/ibexaviation.com\/page-show\/aviation-meteorology\/m19-thunderstorm-hazards-4.jpg\" alt=\"\" loading=\"lazy\"\/><\/p>\n<ul>\n<li>Strong updrafts may produce negative <strong>G<\/strong> forces, while strong down-drafts may produce positive <strong>G<\/strong> forces from middle levels down to the surface.<\/li>\n<li>These vertical currents can cause sudden altitude changes up to approximately <strong>1 km<\/strong> from the thunderstorm.<\/li>\n<li>Down-drafts spreading across the ground generate <strong>squall winds<\/strong> with speeds ranging from <strong>40 to 100 knots<\/strong>.<\/li>\n<li>Strong gusts occur in the transition zone between updrafts and down-drafts and may cause structural damage or loss of aircraft control.<\/li>\n<li><strong>Air pockets<\/strong> are localized regions of rapidly changing pressure and temperature associated with strong vertical air currents.<\/li>\n<\/ul>\n<h3>Wind Shear<\/h3>\n<p>  <img decoding=\"async\" src=\"https:\/\/ibexaviation.com\/page-show\/aviation-meteorology\/m19-thunderstorm-hazards-5.jpg\" alt=\"\" loading=\"lazy\"\/><\/p>\n<ul>\n<li>Thunderstorm wind shear is produced when powerful down-drafts strike the ground and spread outward to heights of approximately <strong>2,000 feet<\/strong>.<\/li>\n<li>During landing, an aircraft may initially encounter a headwind followed suddenly by a tailwind, resulting in a rapid loss of airspeed and possible stall warning.<\/li>\n<\/ul>\n<h3>Icing<\/h3>\n<p>  <img decoding=\"async\" src=\"https:\/\/ibexaviation.com\/page-show\/aviation-meteorology\/m19-thunderstorm-hazards-6.jpg\" alt=\"\" loading=\"lazy\"\/><\/p>\n<ul>\n<li><strong>Clear Ice (Glaze Ice or Translucent Rime)<\/strong> may form between the freezing level and approximately <strong>10,000 feet above the freezing level<\/strong>.<\/li>\n<li>If aircraft icing protection systems are not activated, severe ice accumulation may lead to engine flameout and degraded aircraft performance.<\/li>\n<\/ul>\n<h3>Heavy Showers and Hail<\/h3>\n<p>  <img decoding=\"async\" src=\"https:\/\/ibexaviation.com\/page-show\/aviation-meteorology\/m19-thunderstorm-hazards-7.jpg\" alt=\"\" loading=\"lazy\"\/><\/p>\n<ul>\n<li>Heavy rain significantly reduces flight visibility.<\/li>\n<li>Heavy showers can cause water accumulation on runways, increasing the risk of <strong>aquaplaning (hydroplaning)<\/strong> during landing.<\/li>\n<li>Water ingestion into aircraft engines during heavy rainfall may result in loss of engine power.<\/li>\n<li><strong>Hail<\/strong> is commonly encountered between the freezing level and approximately <strong>25,000 feet above the freezing level<\/strong> and can cause severe structural damage to the aircraft.<\/li>\n<\/ul>\n<h3>Noise, Darkness and Disorientation<\/h3>\n<p>  <img decoding=\"async\" src=\"https:\/\/ibexaviation.com\/page-show\/aviation-meteorology\/m19-thunderstorm-hazards-8.jpg\" alt=\"\" loading=\"lazy\"\/><\/p>\n<ul>\n<li>Hail striking the aircraft or windshield produces loud noise and is usually accompanied by severe turbulence.<\/li>\n<li>Darkness and loss of outside visual references near thunderstorms can lead to spatial disorientation.<\/li>\n<li>Pilots should rely primarily on flight instruments, especially the <strong>Artificial Horizon (Attitude Indicator)<\/strong>, to maintain aircraft attitude.<\/li>\n<\/ul>\n<h3>Instrument Error<\/h3>\n<p>  <img decoding=\"async\" src=\"https:\/\/ibexaviation.com\/page-show\/aviation-meteorology\/m19-thunderstorm-hazards-9.jpg\" alt=\"\" loading=\"lazy\"\/><\/p>\n<ul>\n<li>Rapid pressure changes associated with thunderstorms can produce errors in pressure-sensitive flight instruments.<\/li>\n<li>The altimeter may over-read in the vicinity of thunderstorms.<\/li>\n<li><strong>Low-Level Significant Weather (SIGWX)<\/strong> charts help identify areas of Cumulonimbus development and associated hazards.<\/li>\n<\/ul>\n<h3>Micro-bursts and Macro-bursts<\/h3>\n<p>  <img decoding=\"async\" src=\"https:\/\/ibexaviation.com\/page-show\/aviation-meteorology\/m19-thunderstorm-hazards-10.jpg\" alt=\"\" loading=\"lazy\"\/><\/p>\n<ul>\n<li><strong>Micro-bursts<\/strong> and <strong>Macro-bursts<\/strong> are intense down-drafts that create severe wind shear and violent vertical air currents, typically lasting <strong>1\u20135 minutes<\/strong>.<\/li>\n<li>Wind speeds may exceed <strong>75 km\/h<\/strong> and are often associated with heavy rain or <strong>virga<\/strong>.<\/li>\n<li>During approach, pilots may encounter a headwind, followed by a strong down-draft, and then a tailwind, creating a highly hazardous situation.<\/li>\n<li>A <strong>Micro-burst<\/strong> affects an area less than <strong>4 km<\/strong> in diameter, whereas a <strong>Macro-burst<\/strong> extends over an area greater than <strong>4 km<\/strong>.<\/li>\n<li>Micro-bursts and macro-bursts can cause rapid changes in angle of attack, roll, yaw, turbulence, visibility, aircraft attitude, noise levels, and may result in undershooting or overshooting the runway during approach.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>Aviation Hazards of Thunderstorms Severe
