Amazing! temperature and humidity have such a big effect on airplane flight

We need to understand concepts when we talk about the effect of temperature and humidity on airplane flight, which is the atmospheric density  that refererd to the amount of air or molecules contained in the atmosphere per unit volume. Atmospheric density is one of the main factors that determine the aerodynamic force experienced by objects when they move in the atmosphere, it has an important influence on various aircraft flying in the air.

In the atmosphere, both the temperature and pressure drop with height and density is no exception. As the flying height increases the pressure drops very quickly causing the density of the atmosphere to drop dramatically. The higher the pressure, the higher the thrust of the airplane, but when the pressure is strong, the resistance will be greater and the fuel consumption will not change.


A small amount of water vapor in the air is almost negligible under certain conditions, but under other conditions, humidity may become an important factor affecting aircraft performance. Due to water vapor is lighter than air, wet air is lighter than dry air. The higher the humidity, the lower the air density then cause aircraft thrust the lower, and the higher the fuel consumption.

The higher the temperature, the more water vapor can be contained in the air. Compare two independent air mass, the density of the warm, moist air mass is lower than the cold, dry one. The higher the temperature, the lower the air density then cause aircraft thrust the lower, and the higher the fuel consumption.

Pressure, temperature, and humidity have such an important effect on aircraft flying performance precisely because they directly affect air density may cause harm to the airplane and aviator.

If the air reaches saturation point and the temperature and dew point are very close, fog, low clouds or rain are likely to form. Cumulonimbus clouds are the most dangerous type of cloud for pilots. The thunderstorm is the strong convective weather phenomenon when the cumulonimbus develops to a certain intensity, which including lightning, wind, shower and even hail and other weather phenomena. For example, If an aircraft enters a thunderstorm, the aircraft will encounter ascending or descending air currents exceeding 3000 feet per minute. In addition, the thunderstorms will produce large hail, destructive lightning, tornadoes and large amounts of water, all of these are potentially dangerous to aircraft.

As we all know, It’s hard to get away from a raging thunderstorm, let alone a light airplane. Rain will make the surface of the runway dangerous, and snow, ice, ponding will make it difficult for aircraft to take off and land. That’s why the temperature and humidity sensor is important for airplane flight. As an instrument to measure temperature and humidity data, it is essential to ensure the safety of aircraft flight.

In high-altitude flight, the temperature and humidity sensor probe housing as an important protective tool to protect the chip from damage. It must have a hard appearance, be able to withstand high pressure, corrosion and avoid rust. It can not only enter the ground but also “go up”. The following picture is a foreign customer who purchased the HENGKO temperature and humidity sensor flange probe housing to use on the plane.


HENGKO temperature and humidity sensor have sturdy and durable protective housing, high load capacity, shock resistance, safe and effective protection of PCB modules from damage. The filter is dustproof, corrosion-resistant, waterproof, and can reach the IP65 protection level. It can more effectively protect the humidity sensor module from dust, micro-particle pollution and the oxidation of most chemical substances, ensuring its long-term stable and normal operation, higher reliability and maximum lifetime.

HENGKO can also customize various filter precision and shape sensor housings according to customer requirements and has a professional design engineering team to better serve you.
