What is the Fuel consumption of a Boeing 737?

While the actual fuel consumptions of the Boeing 737 depend on several factors there is an average that is widely used. It is estimated that the Boeing 737 uses about one gallon of fuel every second.

What is the difference between A300 and Boeing 777?

These two planes are very different. The Airbus A300 is joystick flown while the 777 has traditional yokes. The 777 is also longer, has bigger engines and 14 wheels.

What type of engine does a 747-400 have?

The 747-400 uses 3 different engine types;

General Electric CF-6

Pratt & Whitney PW4062

Rolls-Royce RB211

How many passengers can a 747 carry?

Generally speaking, a 747-400 with First/Business Class and coach class holds 524 passengers in an international configuration. In a domestic configuration that number increases to 568 passengers.

What is the cruising speed of a DC-10 jet?

The typical cruise speed for a dc 10 is around 600 miles per hour.

Which is bigger Boeing 747 or DC 10?

A Boeing 747 is considerably bigger than a DC 10 (as well as th aircraft that replaced it the MD 11). The Boeing 747-200 had a Max Take-off Gross Weight of 780,000 lbs. Later models increased to 800,000 lbs or more. The DC10-10 has a MTOGW of 455,000 lbs.

The DC10-30 has a MTOGW of 530,000 lbs.

The MD11 Freighter has a MTOGW of 630,500 lbs. Custermen

How fast does a Boeing 747 travel?

The Boeing 747 travels at 0.85 mach or 567 mph.

Can a passenger plane stop in mid air?

No it cannot. Even with forward momentum, it could not be said to have stopped.

What is flight deck effect in Boeing aircraft?

The flight deck is the name given to the area from which the aircraft is actually controlled, as in, pilot, copilot, flight engineer, and any other persons that are a part of the crew tasked with the actual control of the aircraft. The cockpit is a part of the flight deck.

How do you land boeing 777?

The Boeing 777 can either be landed manual by the pilots, or land with an ILS system or with the more advanced Autoland system, which, basically the plane lands itself.

What is the average speed of a jet plane?

The average speed of a jet plane is about 900 kilometers per hour. However, this is usually measured in knots which refers to nautical miles and this translates to about 500 knots.

What is Boeing 747-400?

A Boeing 747-400 is the largest airplane that Boeing make. It has four engines and was designed in 1988. It is the second most recent Boeing 747 that Boeing have made.

I have 1994 CR 125 and it has very low top end speed when I bought the 125 I noticed that it had 250 fatty pipe on it can that cause slow take off?

Yes. The application of a proper pipe on a two-stroke motor is critical. The 250 pipe has way to much volume and not enough back pressure to allow the 125 motor to "breath" properly. Also check the ignition timing, carb jetting and power valve for proper working order per Honda specifications.

What is organizational stakeholders?

Organizational stakeholders are group of people that have interests in the organization. This idea was first used in the year 1963 at the Standford Research Institute.

How fast does a plane have to go in order to get off the ground?

planes can take off when the lift produced by the wings exceeds the weight of the plane - some variables that determine lift are the speed of air moving over the wings, angle of the wing to the air movement and the shape of the wing which can be changed with the flaps or slats

so its not the ground speed that determines when a plane can lift off but the air speed which can vary with wind speed and direction - and it differs depending if flaps or slats (flaps on the front of the wings) are deployed as they increase lift

another factor that can change lift is air temperature and preasure - higher temps and lower preasure reduce lift and so require more air speed to lift off

the amount of lift required for each plane is determined by not only the weight but the amount of drag from shape of the aircraft and the shape of the wing - which is why take off speed can vary greatly from plane to plane

take off speed can vary from about 32 knots (about 37mph) with a piper cub to nearly 180 knots (about 205 mph) with some supersonic jets whose tiny wings don't produce much lift at slow speeds

some small light high lift aircraft like the piper cub if taking off into a headwind that is equal to their takeoff speed can take off like a helicopter straight up with no ground speed at all

How do planes take off?

An airplane has to reach a certain speed (which varies depending on aircraft type and gross weight) before it can take off,

There are 7 main stages involved with take off in commercial airliner.

1) Checks - when the aircraft has had its IFR and take off clearence from Air traffic control, the pilots must do a series of brief checks, such as flap configuration, APU setting, landing lights and autopilot, After these are done the aircraft will taxi onto the runway.

2) Power up - At this point the throttles will be advanced and the tubines will power up and the aircraft will start accelerating

3) Final check - The pilots will look at their speed gauges, They should be "alive" and displaying increasing numbers by now

4) V1- The "V1" speed is the speed that the aircraft can no longer stop with the amount of runway it has left and must take off no matter what happends.

5) Rotate - This comes about 2 seconds after V1 is called, When the captain says outloud "Rotate"! the first officer will pull back on the yoke or sidestick and the aircraft will pitch up and lift into the air, increasing in speed and pitch angle until both of the desired are reached

6) V2- This is the speed that the aircraft can safley continue the takeoff if an enjine fails, it is usually called about 2 seconds after rotate.

7) Positive rate- This happends about 40 ft off the ground and is usually around 3 seconds after the aircraft has become airbourne, This simply means that the aircraft is climbing and the alitmiters are correctly working, At this point the crew will raise the landing gear, and raise the flaps 1 stage.

This is what the conversation should look like at take off with a functioning crew

(key)

Atc = air traffic control

fo= first officer

cpt=captain

fo: Heathrow tower,Virgin 332 at runway 27 left has received IFR clearence with delta for departure to the east for KORD, Requesting take off IFR over

(that was the first officer asking for clearence from air traffic control, the capatin would be doing the pre takeoff checks while the first officer does this)

atc: Virgin 332 cleared for take off runway 27 left, climb and maintain 4000, remain on runway heading until you have contacted the controller on the departure frequency, good day sir.

fo: Virgin 332 cleared for take off runway 27 left, good day (this must be repeated so the controller is sure the pilots have understood the clearence.

Capt: all checks complete, power up

fo: power to 70%

capt: Airspeed indicators checked

fo: checked

capt: V1!

capt: Rotate!

capt: V2!

capt: positive rate

fo: gear up

capt: gear up and locked, retract flaps to 2 degrees

There is much more involved than this however this is the basics of the process

What is the cruising airspeed of a 757?

Maximum speed: 590 mph at 27,000 ft.

Cruising speed: 520 mph at 34,000 ft.

How fast can a rocket go?

Rockets can achieve speeds of up to 25,000 miles per hour (40,000 km/h) to reach Earth's orbit and beyond. The speed of a rocket can vary depending on its purpose and destination, with some reaching even higher speeds for interplanetary missions.

How fast does a plane take off?

That varies from about 50 mph for a Piper cub to about 150 for an airliner to over 200 for some military jets.
