How do Airplanes Taxi

Yes, currently all airplanes use the push of the motor for taxiing. Handbrakes keep an airplane still in order to nearly reduce the performance.

There has been a system under development for the assessment of electrical motors and you will soon see it on new planes. RE: How do airplanes drive exactly? Breaks (see spelling) can keep the glider in position, even if the thrusters are almost at full throttle. RE: How do airplanes drive exactly? Do you need a tractor for push-back and rolling performance?

Perhaps a predictive drive system would restrict slip so that it works regardless of road surfaces. RE: How do aircraft drive exactly? RE: How do aircraft drive exactly? What kind of brake do pilot use when landing - park brake or rescue brake? Is it mostly push reverser? Just press the brake on the wheels by pressing the top of their oar pods, very similar to in a normal automobile.

You can also set a certain level of retardation using the automatic brake control knob. On the other hand, reverse thrusters support the wheels only to reduce friction. A number of aeroplanes with turbo jets are not even fitted with thrusters, as a secure runway can only be performed to perfection with wheeled braking.

The braking when the aeroplane is decelerating, with the braking being the most important way to decelerate the aeroplane.

A similarity is that of a gearbox car: if you approach a brake lamp, you would use the brake to decelerate it, but if you integrate compressive brake (downshifting the gearbox) into the formula, you can: 1 ) Reduce much of your consumption by decreasing your air pressures and/or service life, or 2) Improve your retardation by using compressive brake in addition to standard brake applications.

RE: How do airplanes drive exactly? Quote Starlion blue (reply 2): Breaks (see spelling) can keep the glider in position, even if the engine is almost at full throttle.

RE: How do airplanes drive exactly? In just about every today's automobile, the electronic system will interrupt the fluid supply when the motor is idling. Even if you brake the motor, your throttle at this point is the same as idling. RE: How do airplanes drive exactly? Quote Goldenshield (answer 7): ....where the brake is the main way to decelerate the plane.

Yes for power calculation, but at least in practical use on the CRJ, the brake is usually only applied when the back feed is adjusted to neutral (below 75 knots). It was similar on the Dash - we braked via Betas and just before the turn-off we braked by bike. RE: How do aircraft drive exactly?

Quote Starlion blue (reply 10): In just about every today's automobile, the electronic system will interrupt the fluid supply when the motor is idling.

Please also consider that the idling mode looks like < 0 in terms of energy efficiency. Of course this is physical impossibility. However, quote Starlionblau (reply 10): Even if you brake the motor, your throttle at this point is the same as idling. RE: How do aircraft drive exactly?

A similarity is that of a gearbox car: if you approach a brake lamp, you would use the brake to decelerate it, but if you include compressive deceleration (downshifting the gearbox) in the calculation, Hehe... now we'll see signposts along the take-off and landing runways saying "no Jake Braking"!

RE: How do airplanes drive exactly? Quote Persistent Fox (Answer 14): "Hehe... now we will see signposts along the takeoff and landing strip saying "no Jake Braking"! Well, the bikes aren't slowed down (directly) by the motors, so I estimate that the equivalents would be "no back thrust". I CONSIDER that Palm 90 has returned from the gate on its own, and I saw here that some rear-engined planes are still doing this.....

RE: How do airplanes drive exactly? The Jake Braking is the previously described technology of shifting down to use the high speeds of the motor to decelerate a lorry.

It is -200 to -900, but the politics is to stop the aircraft on the take-off and landing runways and not to brake to below 80 kn unless it is necessary. RE: How do aircraft drive exactly?

Periodic motor brake application in a compression -ignition (not very effective) or throttle motor is just a technology, and is not loud'. RE: How do aircraft drive exactly? Quote Starlion blue (reply 19): Yeah, I know the posters were originally about locking brake, but I was just saying brake. Yeah, I was thinking locking brake, not windbrakes.

RE: How do aircraft drive exactly? Quote Starlion blue (reply 10): In just about every today's automobile, the electronic system will interrupt the fluid supply when the motor is idling. My feeling was that in a fuel-injecting vehicle, when you take your feet off the gas pedal to get slower, the injector system lowers the amount of gas to zero and you run with it.

RE: How do aircraft drive exactly? My feeling was that in a fuel-injecting vehicle, when you take your feet off the gas pedal to get slower, the injector system will cut the amount of gas to zero and you run with it. No matter in which case (idle or zero) the vehicle of GQFluffy does not seem to work.

RE: How do aircraft drive exactly? According to this, the only pertinent rule of Newtonian is that the further shear must correspond to the drag of the winds and the drag of the ground/wheel. RE: How do aircraft drive exactly? Turbo-props also roll at idling speed. You need some starting performance to get them going, just like a jet, but as soon as they get going, their swing keeps them going and they generally tended to speed up, except in heavy winds (due to the idling, these propulsion units behave like large metallic disks that will decelerate you very effectively).

Interestingly, you can use alpha (reverse idle) to keep them from over-speeding. Does not consume more gas than regular idling on the floor, and it has about the same effect as "braking" (but in a good way). RE: How do aircraft drive exactly?

I saw Ryanair 737-800's in Luton come down from the airstrip and then roll in at what looks like about 30-40 kn and then slowly turn the reversed neutral as they came to curves, they're probably in a rush! I'm so agitated that I wish I could get my trousers wet!

RE: How do aircraft drive exactly? According to this, the only pertinent rule of Newtonian is that the further shear must correspond to the drag of the winds and the drag of the ground/wheel. Lots of drivers also complained that idling is a little too much push for a taxi. You used to turn one of the motors backwards until the service said they should stop doing that.

They' re just heating up the brake now. RE: How do aircraft drive exactly? Turbo-props also roll at idling speed.

Fuel economy is further reduced by switching off the motor. RE: How do planes drive exactly? That's something you'd rather have? In addition, it makes good sense because idling on two motors is still too much push for rolling. Currently my business has 11 aircrafts (a mixture of ATR's, A319's and A343's and soon some A332's).

RE: How do aircraft drive exactly? There have been cases of a ton of petrol being burned on the floor during the taxi before it leaves because of traffic jams at the LHR.

1 ) Spare your brake a great deal of brake life by decreasing the brake force and/or how long they are used, I would much rather use brake on my vehicle than downshift (maunal or automatic) under regular use. RE: How do aircraft drive exactly? I' d much rather use a brake on my vehicle than downshift under regular circumstances (maunal or automatic).

Likewise, the cost of maintaining the reverse throttle is higher than the cost of the brake. RE: How do aircraft drive exactly? Hell, my lorry is 11 years old and has 160,000 mileage on it, and the hitch was changed last year for the first of its kind, and it had modest tear on it for as much stop-and-go as I do.

I also only had to place 1 front brake kit, with the back wheel brake still installed at the works, with quite a few kilometres on them. RE: How do aircraft drive exactly? I' d much rather use a brake on my vehicle than downshift under regular circumstances (maunal or automatic). I' d rather go with a combination of brake and motor brake.

It is not the case that the clutches of a gearbox show much more abrasion during motor brake operation. RE: How do aircraft drive exactly? Given the taxi times used and the superfluous consumption of petrol. RE: How do aircraft drive exactly? Quote Starlion blue (reply 40):
