CULTURALQA 07-2023-23A Q1 Why does an airplane increase itsaltitude during the flight?
A1 Erika Fernandez, Experience in AviationField Apr 25 Airplanes increasetheir altitude during the flight for several reasons. One of the main reasons is fuel efficiency. As the airgets thinner with every foot climbed, planes can travel more easily andtherefore move faster and burn less fuel, saving money.The "sweet spot" of flying is regarded as between 35,000 and 42,000feet, where the air is thin enough to reduce drag on the aircraft, but not sothin that the engines cannot function properly. Flying at a higher altitude can also minimize turbulenceand give pilots more time to fix any emergency situations that may arise. However, flying too high can alsocause problems, as the jet engines need oxygen to work, and flying too high canreduce engine efficiency and cause the engines to burn more fuel. Therefore, thealtitude at which an airplane flies is determined by several factors, includingfuel efficiency, air resistance, wind speed and direction, traffic flow, andterrain. Q2 What is bronze made of, and how weretools or masks made from bronze? A2 Rebecca Williams, Knows all about Homedecoration.
