Why do commercial jets not go faster?
Why do commercial jets not go faster? Typical commercial airplanes are not designed to fly faster than the speed of sound, also known as Mach 1. If they get too fast, the air begins forming shockwaves along the wing that can cause the aircraft to become uncontrollable.
Will planes ever go electric?
Some companies are looking at jet aircraft powered by electricity. For example, Wright Electric is working on a 100-seat fully-electric regional jet that could take off starting in 2026. The Wright Spirit is a conversion of the BAe 146 regional jet, destined for one-hour flights.
Will planes ever get faster?
United Airlines said it will buy 15 “Overture” jets from Boom Supersonic once they meet United's safety, operating and sustainability requirements, with an option for an additional 35 aircraft. The Denver-based company said the planes will be capable of speeds up to 1.7 times the speed of sound, or about 1,300 mph.
Why aren t commercial jets supersonic?
Well, actually there are a couple of good reasons – and a few bad ones. The valid reasons are concerns over sonic boom, fuel economy, and market demand – with the last one being the primary driver. If there are not enough customers buying the planes, companies won't be able to recover their R&D costs or make a profit.
How do pilots know how heavy the plane is?
The operations department of the airline take the passenger, baggage and cargo information and collate this with the basic empty weight of the aircraft and the fuel load as determined by the pilots. They then feed this into a computer to calculate not only the gross weight of the aircraft but also the CoG at takeoff.
Can pilots control the speed of the plane?
Pilots will mostly set the speed they want. In cruise, the planes tend to be further apart, and speed is less critical. Different planes fly at different speeds, and ATC usually uses altitude and heading as the primary means to separate them.
What happens if a plane flies too fast?
In jet aircraft, an overspeed results when the axial compressor exceeds its maximal operating rotational speed. This often leads to the mechanical failure of turbine blades, flameout and total destruction of the engine.
What happens if a plane lands too heavy?
The MLW is set in order to ensure safe landings; if an aircraft weighs too heavy during touchdown, it may suffer structural damage or even break apart upon landing.
Are pilots allowed to fly faster?
While pilots possess the ability to enhance their speed, they must also abide by air traffic regulations, speed limits, and predetermined flight routes.
Do military jets fly higher than commercial?
Most US military aircraft can exceed 50,000 feet, if they really really try. Again, the limits are classified. Most commercial jetliners cruise somewhere between 30,000 and 45,000 feet above mean sea level.
Do planes ever stop flying?
Techincally, there is only one way for the aircraft to remain hanging motionless in the air: if weight and lift cancel each other out perfectly, and at the same time thrust and drag cancel each other out too. But this is incredibly rare. To stay in the air and sustain its flight, an aircraft needs to be moving forward.
How fast is a plane going when it takes off?
Typical takeoff air speeds for jetliners are in the range of 240–285 km/h (130–154 kn; 149–177 mph). Light aircraft, such as a Cessna 150, take off at around 100 km/h (54 kn; 62 mph). Ultralights have even lower takeoff speeds.
Can commercial planes fly faster than they do?
Answer: The direct answer is yes, but there are other considerations that have to be taken into account, such as increased fuel burn and maximum safe speed. Sometimes the flight crew can increase ground speed by selecting a different altitude to get more benefit from the wind.
Why do planes fly at 35000 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.
Can pilots sleep while flying?
Many airlines provide crew rest areas on their aircraft, where pilots can sleep during long-haul flights. These areas are usually located in the tail, cargo area or above the cabin of the plane and are designed to be as quiet and comfortable as possible. Other crew members prefer to use business class seats to rest.
Do pilots get tired of flying?
Fatigue is particularly prevalent among pilots because of unpredictable work hours, long duty periods, circadian disruption, and insufficient sleep. These factors can occur together to produce a combination of sleep deprivation, circadian rhythm effects, and 'time-on task' fatigue.
