Do you burn more fuel at a higher altitude?
Do you burn more fuel at a higher altitude? In the case of gasoline engines, the higher altitude theoretically leads to lower fuel consumption due to lower throttle frictions due to the wider throttle opening. From the other side, as the air is less dense at higher altitudes, the vehicle aerodynamic is changed and this also leads to lower fuel consumption.
Do I need to adjust my car for high altitude?
In higher altitudes, the levels of oxygen in the air are lower. For this reason, your engine idling needs to be raised. You'll find how to do it in the car's instruction manual. Alternatively, seek the advice and help of a professional car mechanic.
What altitude is most efficient for planes?
Optimum cruising altitude is a delicate balance between air density, lift, drag, and engine performance. Thinner air at high altitudes means less drag, but also less lift and less power. Today's modern jetliners are optimized for about 35,000-40,000 feet for the best speed and fuel efficiency.
Why do planes fly at 32000 feet?
Aircraft are much more efficient when flying at higher altitudes. Have you ever wondered why passenger airplanes always cruise at altitudes of 30,000 and higher above mean sea level? The reason is twofold: firstly, the plane can fly faster and, secondly, it is much more efficient money-wise.
At what altitude can planes no longer fly?
Most commercial airplanes have a certified maximum altitude of about 40,000 to 45,000 feet. Regardless of its certified maximum altitude, if an airplane flies too high, it may fail in one or more ways. For starters, the engine may suffocate from a lack of oxygen.
Why do planes cruise at 30000 feet?
The reason planes cruise at high altitudes is that they burn less fuel and can fly faster, as the air is less dense. At 30,000 feet and higher, it is also possible for aircraft to avoid weather systems, making it more comfortable onboard.
