	How To Increase Reverse Thrust In FS2002
		The thrust reverse indicators light up as usual and I am listening to the excellent sound of the engines howling up while moving down the runway, which is a real treat for us noise nuts.
		The power of the reversers is by far less stronger than in old FS98 where you could almost feel the sudden drag when the reversers were activated.
		From now on, with the combined forces of both the reverse thrust and the wheel brakes there should be no problem to stop in time even on shorter runways.

	Reverse thrust - Wikipedia, the free encyclopedia
		Reverse thrust is the temporary diversion of a jet engine's output so that the exhaust gases are blown forwards rather than backwards.
		Reverse thrust is used by many jet aircraft to help slow down just after touch-down, thus reducing wear on the brakes and enabling the aircraft to use shorter runways.
		The reversers are usually clearly visible at the rear of the engines during use.

	Thrust - Wikipedia, the free encyclopedia
		The forward thrust is proportional to the (mass of the air) multiplied by (average velocity of the airstream).
		The resulting thrust pushes the ship in the equal and opposite direction to the sum of the momentum change in the water flowing through the propeller.
		A rocket (and all mass attached to it) is propelled forward by a thrust force equal to, and opposite of, the time-rate of momentum change experienced by the exhaust mass accelerating out from the combustion chamber through the rocket nozzle.

		The reverse thrust levers are physically attached to the thrust levers.
		Some airplanes were designed to be able to use reverse thrust in the air to help facilitate descent, such as the DC-8, but the majority of airplanes have a mechanical stop to prevent inadvertent reverse thrust in flight or whenever forward thrust is being used.
		Reverse thrust enhances stopping capability and helps prevent wear and tear on the brakes, but it is not actually required and not considered when the manufacturer calculates the stopping distance capability of the airplane.

	Aerospaceweb.org \| Ask Us - Reducing Landing Distance
		As discussed in a previous question, thrust reversing is a process used to help reduce the distance a plane travels during landing.
		One common misconception about thrust reversing is that the engine itself actually runs in reverse, but this is not the case.
		This research continued through the mid-1970s and proved that thrust reversers could be used to provide a very steep and rapid descent to follow a desired flight path.

		Reverse gear often does little to slow the boat and will usually swing the stern to one side or another due to prop-walk.
		One may also use the rudder to vary the direction of boat thrust, to aid in holding the boat to or in swinging the boat away from the pier.
		Reverse must often be used to prevent the boat from approaching the slip to fast.

		Even for aircraft, which are approved for in-flight operation of the thrust reverser under JAR 25.933(b), the provision introduced by JAR 25.1155 enables the pilot to be aware, when the selection from forward to reverse thrust is made.
		This is not known to be the case for thrust reverser designs, where the ground/air interface signalling has been sufficiently reliable to not require an over-ride.
		However, the basic concern about the need to avoid a reversing condition, outside any approved operating regime, is the same for a thrust reverser equipped aircraft, as it is for a propeller powered aircraft i.e.

	Restricting The Use Of Reverse Thrust As An Emissions Reduction Strategy (Site not responding. Last check: 2007-09-01)
		Reverse thrust is commonly used along with wheel brakes to slow aircraft during landing and to power-back aircraft away from a boarding gate.
		Currently, air pollution emissions generated during reverse thrust are not included in airport emissions inventories.
		Since the majority of aircraft NOx emissions occur off-airport during climbout and approach, reverse thrust can be responsible for an additional 15% or more of the on-airport NOx.

	Airliners.net Tech Ops: Why Use Reverse Thrust On Long Runways
		Also, it costs a lot more to replace and service thrust reverser parts than it is to change a few brake discs on certain aircraft, so even within the same airline, there may be different policies on reverse thrust usage from fleet to fleet.
		Thats correct,there is an EPR Temp detent on the R/T lever for the B732 for the JT8Ds.
		(in most aircraft such as 737,747,319,320,330) when the reverse thrust is applied, a rear section of the engine cowling deflects backward effectively redirecting the thrust from the rear of the engine to the sides and front.

	WEEK 2 summary (Site not responding. Last check: 2007-09-01)
		Faulting is a common mechanism for deformation of the upper part of the continental crust, which behaves brittlely, under typical conditions of temperature T<300°C. Faults are grouped according to the motion they accommodate, into three main categories: Normal, reverse/thrust, and strike-slip faults.
		Reverse faults show upward motion of the hanging wall and accommodate bulk horizontal shortening of the crust.
		Flat thrusts are common in mountain belts, and obviously, these flat structures have an interesting relationship with mountainous topography.

	RE: Airplane reverse thrust
		Remember that the thrust that gives acceleration to a jet is caused by the change in momentum of the air that passes into and then out the back of the jet engine.
		When reverse thrusters are deployed vanes partially block the exhaust gases coming out the back of the engine, and some of the exhaust gas becomes diverted (to directions which are mostly up and down) from the back of the engine.
		Some of the exhaust gases, therefore, obtain a change in momentum, and it is the reverse- thruster vanes which provide the change in momentum.

		I imagine it would be usfull to have brakes and be able to reverse.....
		I did think that reverse thrust would be worth having - but having used my craft for a couple of seasons, now I agree with Russ.
		it is possible to have the craft set up so that you have virtually full thrust before you get adequate lift - which isn't ideal, as the only way to slow down is drag the skirt, and then you're a hairsbreadth from ploughing in.

		The fan of the cart was turned on and the cart was pushed away from the sensor giving it an initial velocity in the opposite direction of the thrust from the fan.
		We gave the cart reverse thrust and pushed it away from the sensor so that it would reverse and come back.
		Second, since there is a constant force and a constant negative thrust, there will be a constant negative acceleration because of the equation a = F / m.

		To do this, you press and hold F2 until you open reverse thrust as much as you think is needed.
		Maybe not in FS, where the brakes feel the same way as the reversers and there is no (or little) danger of the front wheel collapsing.
		but the fact is, you should always land and then open reverse thrust when the nose hits the ground.

		Thrust and Reverse faults form by horizontal compressive stresses and so cause shortening of the crust.
		Thrust faults typically dip at low-angles, between about 10-40 degrees.
		However, because thrust faults cut through stratigraphic sections as either ramps or flats, their orientations can vary considerably.

		The older ones, THROTTLEn_SET, offer a reverse range -- anything below zero (down to the max reverse thrust which varies, but is typically -4096 -- FSUIPC calibrates to this nominally but varies it in practice according to the aircraft).
		Using these older values is the only way to get the reverse thrust on an axis input.
