Everyone knows that bad weather conditions like heavy downpour or thunderstorm causes the airlines to delay or cancel the scheduled flights. But what majority of people do not know is that flights do get cancelled or delayed because of extreme heat, too. However bizarre it may sound, it is true. So, when you are flying during a weather that is expected to hit the ceiling level of hot temperature, make sure you book cheap flights to such places so that your pocket doesn't feels the brunt of it, in face of cancellation.
The reason behind flights finding it difficult to take off in scorching heat is purely scientific in nature. When temperatures soar extremely high, air expands causing the air density to get low. As air expands, the air molecules dissipate and get fewer invariably affecting the lift which is needed by the flights to take off.
When the lift is less due to thin air caused by extreme heat, flights take off requirement increases. There is more thrust needed to take off along with a long runaway distance for the flight to catch up the speed to fly. All this requirements if not met during extreme hot temperatures maims the flight from its operations.
As per the reports, aircrafts are built to sustain a maximum temperature of 118 degrees. Beyond this specified temperature the aerodynamics capabilities and output of the engine is affected. At extreme heat state, the engines of the aircraft may also wear out, impairing the brakes and internal machinery. Thus, aircrafts are directed to seize flying under such extreme conditions.
Mostly aircrafts that are smaller in sizes face problems during these rising temperatures. Big planes have wider and larger wings that are somehow able to withstand such heat pangs but it is recommended that even they do not fly.
Aircrafts that fly to places which are arid and flaming should be built accordingly to sustain such boiling temperatures. The flight's passenger capacity and cargo limit should be curtailed so that it can take off easily. Also, the airlines could try and lower the flights fuel level as this will cause the flights to take a halt for refueling at stopover that could be scheduled in cooler places.
The airlines should try to schedule flights to take off and land during early morning or late night in places that get extremely hot. This is a practice that is generally undertaken by airlines in the Gulf countries that experience extremely high temperatures.
So, schedule your flying to destinations that get very hot by checking the weather forecast and booking last minute flights.
