Variations in aircraft weight do not affect the glide angle provided that the correct airspeed is flown. Since it is the lift over drag (L/D) ratio that determines the gliding range, weight will not affect it. … The only effect weight has is to vary the time the aircraft will glide for.
How does weight affect an airplane?
Weight is the force that pulls the plane down due to gravity. In order for the plane to get off the ground, the plane must overcome its weight throught the force of lift. The more mass the plane has the more lift it has to produce in order to get off the ground.
How can we increase aircraft range?
7 Flying Tips to Extend the Range of Your Plane 20%
- Catch a Ride with Mother Nature! …
- Have you ever noticed that the dinosaur engines we use many designed in the 60s and 70s use fuel to cool themselves in climb since they are air cooled and they need help when they are run at high rpms. …
- Practice your Best Glide Speed! …
- Use available technology! …

How weight and balance affect the performance of an aircraft?
Weight and balance have a direct effect on the stability and performance of the aircraft. If a plane is too heavy, it may never get off the ground. If it’s out of balance, it may be uncontrollable when it does take flight. … Maintaining proper weight and balance is an extremely important balancing act.
Does weight distribution matter on planes?
“For the Boeing 737 and Airbus A320 families there is no weight and balance problem flying empty or nearly empty as long as the passengers are evenly distributed throughout the cabin. The aircraft will be in balance. This is of course all checked before departure by the pilots,” Brady said.
What’s the most dangerous part of flying?
Boeing research shows that takeoff and landing are statistically more dangerous than any other part of a flight. 49% of all fatal accidents happen during the final descent and landing phases of the average flight, while 14% of all fatal accidents happen during takeoff and initial climb.
Do planes get weighed before takeoff?
Aircraft are not weighed prior to each flight, but the basic empty weight must be known and checked periodically per regulation.
What is maximum range speed?
The speed which gives the maximum range for a given aircraft weight and altitude is called best range speed. Flying at higher speeds than the best range speed increases the drag and the fuel flow, and therefore reduces the range.
How is aircraft range calculated?
- On this page we summarize the information necessary to do a preliminary calculation of an aircraft’s range under cruise conditions. …
- L = W = Cl * .5 * r * V ^2 * A. …
- V = sqrt[ W / (.5 * Cl * r * A)] …
- F = D = L / (Cl/Cd) = W / (Cl/Cd) …
- t max = M / (TSFC * F) …
- R = V * t max.
What is long range cruise speed?
The traditional speed is long-range cruise (LRC). LRC speed is interrelated with maximum-range cruise (MRC) speed, which is the speed that will provide the furthest distance traveled for a given amount of fuel burned and the minimum fuel burned for a given cruise distance.
How often does an aircraft need to be weighed?
When operating under FAR 135, an aircraft must be weighed every 36 calendar months to establish its current empty weight and center of gravity.
What is minimum fuel in aviation?
Minimum Fuel. … “Indicates that an aircraft’s fuel supply has reached a state where, upon reaching the destination, it can accept little or no delay. This is not an emergency situation but merely indicates an emergency situation is possible should any undue delay occur.”
Who is responsible for the correct weight and balance of every flight?
1-1] The pilot in command of the aircraft has the responsibility on every flight to know the maximum allowable weight of the aircraft and its CG limits.
Can a plane be overweight?
In addition to operational considerations, overweight operations can have negative physical effects on your aircraft. Many aircraft have landing weight restrictions, with landings over that weight potentially causing damage over time to the landing gear or other stress points in the aircraft.
Why do airlines fly with empty seats?
The empty seats had been a result of low demand for air travel combined with airline policy meant to encourage people to feel safe about flying.
What is the force that opposes weight and allows an airplane to fly?
Lift works opposite of weight. Thrust works opposite of drag. When the forces are balanced, a plane flies in a level direction.
