Do planes fly faster if they are lighter?

With a heavier aircraft, your AOA in cruise is closer to the critical AOA, causing you to stall at a faster airspeed. A lighter aircraft will have more degrees of AOA to increase before it encounters the critical AOA, causing you to stall at a lower airspeed.

Regardless, on average, heavier designs typically fly faster than lighter designs. This is kind of intuitive if you think about it. For any given wing area (and all else being equal) more weight requires faster speed though the air in order to maintain sufficient lift.

Kind of. If you load an aircraft more, it needs, from it's wings, more lift force to balance the now greater force of gravity pulling it down. That larger lift force can be obtained in three ways. By increasing the airspeed, by increasing the angle of attack, by changing the wing geometry.

Answer: You are correct that a twin-engine jet will have an average takeoff run of 30 – 35 seconds, good observation. It will vary depending on the altitude of the airport, the weight of the airplane and the outside temperature. The lift-off speed (VR) will also vary depending on the weight.

A headwind will reduce the ground speed needed for takeoff, as there is a greater flow of air over the wings. 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).

This makes it very hard to say that one airplane is significantly safer than another. They are both safe — even if one type has a slightly higher accident rate, that rate is still infinitesimal. Q: Is a four-engine 747 safer than a two-engine 777? A: No, they are both safe.

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.

Airplane wings are shaped to make air move faster over the top of the wing. When air moves faster, the pressure of the air decreases. So the pressure on the top of the wing is less than the pressure on the bottom of the wing. The difference in pressure creates a force on the wing that lifts the wing up into the air.

Do commercial planes fly at maximum speed? Large commercial jets fly from 550 to 580 miles per hour, but their landing and take-off speeds vary. Most commercial jets fly from 160 to 180 miles per hour, with landing speeds ranging from 150 to 165 miles per hour.

In general, commercial airlines are designed to handle crosswinds up to 30-40 knots (approximately 35-46 mph), and some planes are capable of landing in even higher winds.

Number 1: North American X-15 This aircraft has the current world record for the fastest manned aircraft. Its maximum speed was Mach 6.70 (about 7,200 km/h) which it attained on the 3rd of October 1967 thanks to its pilot William J. “Pete” Knight.

In the event of an engine malfunction, the recognition of a significant abnormality, or an ATC instruction to stop the aircraft during the take off roll, transport aircraft in Performance Category 'A' should be able to safely reject the take off if the decision to do so is made at a speed not greater than the correctly ...

So in summary, the sinking feeling you get after takeoff is a result of your inner ear's response to the sudden change in acceleration and gravity as the plane leaves the ground. It's a completely normal sensation and nothing to be concerned about.

Why do planes shake on take off? The shudder that many airline-type planes experience just after lift-off is usually caused by out-of-balance landing gear wheels still spinning after they have left the ground. Normal practice is to apply the wheel brakes at that point, then retract the gear.

Whether flying at night or during the day, pilots need to see some kind of horizon. They use this to determine the airplane's attitude. At night pilots will turn their gaze from outside to inside and use the artificial horizon. The artificial horizon is normally a simply globe split into two hemispheres.

Yes, an aircraft can stay in the air without going forward if the oncoming wind, called headwinds are equal or greater than th minimum speed of that aircraft. This principle is used in the wind tunnels to experiment the flight characteristics by blowing the wind to the aerofoil and assess the aerodynamic changes.

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.
