Our planet’s rising temperatures are making it harder for planes to take off at certain airports, presenting yet another challenge to civil aviation. And as heatwaves become more frequent, the problem could extend to more flights. Lift depends on several factors, but one of the most important is the temperature of the air – and as the air warms up it expands, so the number of molecules available to push the plane up is reduced. Planes get 1% less lift with every 5.4 degrees Fahrenheit (3 degrees Celsius) of temperature rise. “That’s why extreme heat makes it harder for planes to take off – and in some really extreme conditions that can become impossible altogether. The problem particularly affects airports at high altitude, where the air is already naturally thinner, and with short runways, which leave the plane with less room to accelerate.

Understanding Density Altitude: How Temperature and Humidity Affect Aircraft Performance ✈️ Density altitude is a crucial concept in aviation, directly influencing aircraft performance by altering air density. Unlike pressure altitude, which measures height above sea level based on standard atmospheric pressure, density altitude accounts for temperature, humidity, and pressure variations to reflect how “dense” the air feels to an aircraft. In cold, dry air, molecules are tightly packed, resulting in low density altitude. For instance, at 6,000 feet in such conditions, higher air density allows engines to perform optimally and wings to generate more lift, enhancing takeoff, climb, and landing performance. Conversely, warm and moist air creates a high density altitude environment. At an equivalent pressure altitude of 14,000 feet, reduced air density significantly impacts performance. Warm air causes molecules to spread apart, and moisture further reduces air density since water vapor is lighter than dry air. This leads to less efficient engine power, reduced lift, and longer takeoff distances, making flying more challenging, especially for heavily loaded aircraft. Standard atmospheric conditions at 10,000 feet serve as a baseline, where neither extreme significantly affects performance. However, pilots must always consider density altitude changes due to weather, as they can impact aircraft handling and safety. Understanding density altitude helps pilots plan for conditions that may affect fuel efficiency, climb rates, and overall flight safety, particularly in high-altitude or hot-weather environments. This knowledge is vital during operations in areas with extreme weather variability. #densityaltitude #humidity #temperature #aircraft #aviation #flight #SasidharanMurugan #Itzmemsd

The main reason is density altitude, which is the altitude relative to standard atmospheric conditions at which the air density would be equal to the indicated air density at the place of observation. In other words, the density altitude is the air density given as a height above mean sea level. Ideally, at that 35,000ft or 11,000m the air temperature is -56.5°C and the air density is 0.364 kg/m^3 . The air gets thinner the higher you go. When the air is thinner, planes can fly faster and more efficiently, using less fuel to maintain the speed required to develop lift. Because high density altitude has particular implications for takeoff/climb performance and landing distance, pilots must be sure to determine the reported density altitude and check the appropriate aircraft performance charts carefully during preflight preparation. As far as air traffic is concerned: Generally speaking, aircraft flying south, southwest, west, and northwest must be at an even altitude, like 36,000 feet. Aircraft flying north, northeast, east, and southeast must fly at an odd altitude, like 37,000 feet. This enables air traffic controllers to safely space aircraft flying at different altitudes. Aircraft are allowed to pass within 1,000 vertical feet of one another, which is one of the reasons why planes stick to 1,000-foot increments for cruising altitude. #aviation

Aircrafts ✈️Fly In Circles ⭕️ And Curvature Of The Earth 🌏; Not In Straight Lines⛔️ Concepts related to aerial operations and the curvature of the Earth. 🛩️ **Curvature of the Earth**: The Earth is approximately spherical in shape, and this curvature can impact various aspects of aviation. As altitude increases, the effect of the Earth's curvature becomes more prominent. For instance, at higher altitudes, pilots may need to take into account the Earth’s curvature when plotting a course, especially on long flights. 🛩️**Geodesic Flight Paths**: In aviation, the most efficient routes between two points are often along what are known as great circles. A great circle is the shortest path between two points on the surface of a sphere. Since the Earth is a sphere, a path that looks curved on a flat map may be the most direct route over the Earth's surface. 🛩️ **Coronal Effects**: When flying at altitude, the aircraft's trajectory may also be affected by the rotation of the Earth—the Coriolis effect can influence wind patterns and ultimately impact flight plans. 🛩️ **Holding Patterns**: In an air traffic control context, aircraft may enter holding patterns, which are typically circular or oval. These patterns are used to manage traffic delays and keep planes spaced safely apart, especially while waiting for landing clearance. Do you know aircrafts don’t fly in straight? As always speculated. #aviation #aircraft #greatcircle #flight #pilots #airport #curvature

There are unique challenges our industry faces! 🛫 Did you know that despite flying at altitudes over 30,000 ft, most aircraft still avoid the Tibetan Plateau? 🏔️ The reasons are compelling: 1. Emergency descent limitations due to high average elevation (14,000 ft) 2. Lack of airports for emergency landings 3. Increased fuel consumption due to air turbulence caused by mountainous terrain It's a testament to how geography and atmospheric conditions shape our flight paths.

🛫 Understanding QNH, QFE, and STANDARD in Aviation In aviation, the terms QNH, QFE, and STANDARD represent different pressure settings used by pilots to calibrate their aircraft altimeters. Here's a breakdown of their key differences QNH QNH is a pressure setting used to set an aircraft's altimeter to indicate altitude above sea level. When set, the altimeter shows the true altitude above sea level. QNH is commonly used during low and medium altitude flights. Pilots obtain this value from local weather reports to ensure accurate altitude readings above sea level. QNH values are reported in METARs (aviation weather reports) and adjusted for local atmospheric pressure. QFE QFE refers to the atmospheric pressure setting that calibrates the altimeter to show altitude above ground level. It is primarily used in some European countries. QFE is important for low-altitude flights where accurate terrain clearance is essential. It sets the altimeter to read zero when the aircraft is on the ground. Like QNH, QFE is based on local atmospheric pressure but adjusted for altitude above the ground. STANDARD The STANDARD setting uses a fixed reference pressure of 1013.25 hPa (hectopascals) or 29.92 inHg (inches of mercury). STANDARD is utilized at higher altitudes, ensuring uniformity for navigation and separation between aircraft across different regions and weather conditions. This setting remains constant and is applied during high-altitude flights or when transitioning through airspaces with varying atmospheric pressures. Aircraft maintain "flight levels" based on this standard pressure. Differences QNH: Sets the altimeter to indicate altitude above sea level, based on local pressure. QFE: Sets the altimeter to indicate altitude above ground, also based on local pressure. STANDARD: Uses a fixed pressure setting (1013.25 hPa or 29.92 inHg) for consistent altitude measurement at high altitudes. Each pressure setting serves a unique purpose in aviation, ensuring precise altitude measurement for safe navigation and operational efficiency. #Aviation #AltimeterSettings #PilotTraining #Aerospace #AviationSafety #SasidharanMurugan #Itzmemsd Dr. Sasidharan Murugan
