Impact of Extreme Heat on Aviation

    With summer upon us, record breaking heat waves has impacted the aviation operations.  Throughout this summer, several regions across the globe experienced an unprecedented heatwave, with temperatures reaching new highs.  Major airports in affected areas witnessed the brutal consequences of this extreme heat, ranging from reduced aircraft performance to flight cancellations and delays.  The reason I choose this event is because extreme heat is a dangerous weather conditions, that we rarely associate with adverse aviation effects, unlike storms or snow.  This event highlights the urgent need to adapt to the changing climate patterns that are influencing flight safety and operations.

As temperatures soar, the impact of heat on aviation operations becomes evident, with reduced aircraft performance and thinner air presenting significant challenges.  As the temperature climbs, air density decreases, resulting in the air becoming thinner.  For aircraft, this equals to reduced lift, making takeoff and maintaining altitude more difficult.  Engine performance is also affected, leading to longer takeoff distances and decreased fuel efficiency. In addition to reduced aircraft performance, extreme heat also affects an aircraft's takeoff weight.  Airports may impose weight restrictions on planes to compensate for the reduced lift capability caused by the thinning air.  This situation could lead to fewer passengers, less cargo, or reduced fuel onboard, ultimately impacting the efficiency of the aircraft.

 Pilots and passengers face the challenge of increased turbulence and weather hazards.  The rising heat creates thermals and turbulence, causing discomfort for passengers and posing challenges for pilots.  The instability during heatwaves may lead to thunderstorms and severe weather events, further impacting flight safety.  One personal experience temperature increase turbulence is the approach to Las Vegas Airport.  During hotter periods, the aircraft constantly run in to pocket of turbulence and making the ride "exciting" for some.

    The impact of extreme heat on aviation operations is a critical concern that we must confront head-on. As temperature continues to increase, it is important for aviation industry to adapt and implement measures to safeguard passengers, crew, and aircraft.
