Forced landing
An immediate landing, on or off an airport, necessitated by the inability to continue further flight. Atypical example of which is an airplane forced down by engine failure.
Forces Acting on an Airplane
The airplane in straight-and-level unaccelerated flight is acted on by four forces. The four forces are lift, gravity, thrust and drag.
Forced Landing Without Power
A maneuver often practiced during training for the license and usually only when the pilot is up for the biannual flight review. We touch this subject as it is intimately related to best glide speed.
Forces in a climb
It was said above that in cruise the difference between the current power requirement and power available - the excess power - can be used to accelerate the aircraft or climb, to accelerate and climb, ...

equilibrium
Maintaining a steady flight requires a balance, often described as an equilibrium of all the forces acting upon an airplane. Weight, lift, thrust and drag are the acting forces on an airplane.

Forces on an Airplane There are four forces that act on an airplane. The motion of an aircraft depends on the relative magnitude of the forces.
force - A push or a pull in a certain direction, that can be measured. Examples of forces are your hand pushing on a doorknob, and a propeller pulling an airplane through the air.
Forced Air Deicing Method
This is a method of deicing using a concentrated flow of air under pressure to remove
contamination from an aircraft, which may be used in conjunction with deicing fluids.

Force. That which produces or tends to produce a change of motion or shape of a body. Measured in pounds or dynes.

Figure 4.15 shows the corresponding forces. We see that whereas the coefficient of parasite drag was more or less constant, the force of parasite drag increases with airspeed. If somebody says “the drag is a ...

The Force on an Airfoil
But let us look today at following basic airfoil requirements and later on see how we have to design the wing so that the same requirements can be further improved upon (or at least not lost!).

inertia force - a force due to inertia, or the resistance to acceleration or deceleration.
resistance - symbol: R. The opposition to the flow of electrons offered by a device or material. Opposition by resistance causes a loss of power.
Forces applied to a spinning rotor disk by control input or by wind gusts will react as follows:

afterburner
Device that injects additional fuel into the specially designed jetpipe of a turbojet to provide augmented thrust. Also called reheat.
The force generated by the movement of air across the wings of an aircraft. When enough lift is generated to overcome the weight of an aircraft, the aircraft rises.

Military forces use helicopters to conduct aerial attacks on ground targets. Such helicopters are mounted with missile launchers and miniguns.
DRAG - A force exerted on a moving body in a direction opposite to its direction of motion.
DRAG CHUTE - A heavy-duty parachute attached to an aircraft's structure which can be used to reduce its landing run.
Drag.
Force of air against aircraft acting in opposite direction of the airspeed vector projected into horizontal plane; Symbols: D; Typical Units: lbf,kip; Dimensions: Mass * Length / Time-squared; ...
Thrust: Force, created by engines and rotors, acting in the direction of the engine.
Time constant: Constant for a first-order filter determining time at which the output of the filter reaches nearly 0.6321 percent of a step input.
Drag is the force that resists movement of an aircraft through the air. There are two basic types of drag: parasite drag and induced drag.

The Royal Air Force was impressed with its performance and in June, 1936, it ordered 310 aircraft. The Supermarine Spitfire Mk. I went into production in 1937 and was operational in June, 1938.
AFB - air force base, usually U.S. or Canadian.
AFCS - automatic flight control system, an advanced autopilot. Also IFCS, integrated flight control system.
AFDS - Autopilot and flight director system.
DRAG Resisting force exerted on an aircraft in its line of flight opposite in direction to its motion. Opposite of thrust.
extra tail downforce requires more lift from wing resulting in greater induced drag. This means higher fuel consumption and reduced range; ...
LIFT - The force exerted on the top of a moving airfoil as a low-pressure area that causes a wingform to rise.
Torque The force which tends to cause rotation.
TR Abbreviation for Torque Roll, a 3D manuever which begins as a hover and the torque of the engine/propeller rotates the model in a counterclockwise direction without any aileron (roll) inputs.

Remember that force or power must be applied to overcome this resistance and the lessening of such resistance decreases the power necessary. A parallel illustration is to think of the power necessary to push a board sideways through water.

Normally the quick explanation for this is the need to overcome acceleration G-forces.

How often does the average general aviation pilot get to ferry a trainer aircraft to the U.S. Air Force Academy?
Aircraft wings are designed to take advantage of that fact and create the lift force necessary to overcome the weight of the aircraft, and get airplanes off the ground. The undersides of wings are more or less flat, while their tops are curved.

at subsonic speed, the magnitude of the aerodynamic moment remains nearly
constant even when the angle of attack changes.

However, landing gears (e.g. those of commercial airliners) are designed to withstand enormous side forces so that if the plane touches down with a significant crab angle, it won't necessarily be damaged.
With drooped or raised wing tips, the vortex is forced further out. Drooped wing tips are often seen on STOL aircraft, but they create a weight penalty since they need to be added to the wing.

Press the trim button in opposition to the rotational force exerted on the aircraft; in other words, if your helicopter is veering off to the left, apply a few clicks to the right trim button until it begins to fly straight.
