For fixed-wing aircraft, single syllable words denoted piston-prop and turboprop, while multiple syllables denoted jets.

For fixed-wing aircraft it is advantageous to perform take-offs and landings into the wind to reduce takeoff roll and reduce the ground speed needed to attain flying speed.

For balloons, helicopters and some specialized fixed-wing aircraft ( VTOL aircraft such as the Harrier ), no runway is needed.

For example, fixed-wing aircraft must make banked turns because they use air pressure to operate.

For fixed-wing aircraft, autorotation is the tendency of an aircraft in or near a stall to roll spontaneously to the right or left, leading to a spin ( a state of continuous autorotation ).

For non-standard vehicle types ( vehicles other than piloted, fixed-wing and self-propelled aircraft which are wholly supported by aerodynamic lift from liftoff to touchdown ), a final symbol is added after the basic mission symbol to identify the vehicle type.

For aircraft with joint registration, one country is designated as the registration state for the purpose of the convention.

Aircraft with special characteristics that give them unique capabilities will often display those in their demos ; For example, Russian fighters with Thrust vectoring may be used to perform Pugachev's Cobra or the Kulbit, among other difficult manoeuvers that cannot be performed by other aircraft.

For instance, slower lighter aircraft are usually allowed closer and lower to the crowd than larger, faster types.

For example, while the behavior of hypersonic flow is understood, building a scramjet aircraft to fly at hypersonic speeds has seen very limited success.

For the last two years of Clinton's presidency, U. S. aircraft routinely attacked hostile Iraqi anti-air installations inside the Iraqi no-fly zones.

For example, flight instruments measure variables such as wind speed and altitude to enable pilots the control of aircraft analytically.

For example Major General Charles J. Dunlap, Jr. says that United States Air Force culture includes an egalitarianism bred from officers as warriors who work with small groups of enlisted airmen either as the service crew or onboard crew of their aircraft.

For example, in German: Oldtimer refers to an old car ( or antique aircraft ) rather than an old person, while Handy refers to a mobile phone.

For aircraft decompression incidents at altitude see:

For example, mountain airports such as Reno ( KRNO ) offer significantly different instrument approaches for aircraft landing on the same runway, but from opposite directions.

For high speed aircraft moving at transonic speeds the effects of incompressibility can't be neglected.

For example, consider the flow of air over an aircraft wing.

For example, there are now only a small number of manufacturers of civil passenger aircraft, though Brazil ( Embraer ) and Canada ( Bombardier ) have participated in the small passenger aircraft market sector.

For example, the phenomenon of flutter in aerodynamics occurs when an arbitrarily small displacement of an aircraft wing ( from its equilibrium ) results in an increase in the angle of attack of the wing on the air flow and a consequential increase in lift coefficient, leading to a still greater displacement.

For example, the instructions involved in updating financial records are very different from those required to duplicate conditions on an aircraft for pilots training in a flight simulator.

For transportation, the prime minister is granted an armoured car and shared use of two official aircraft — a CC-150 Polaris for international flights and a Challenger 601 for domestic trips.

For similar reasons, objects intended to avoid detection will not have inside corners or surfaces and edges perpendicular to likely detection directions, which leads to " odd " looking stealth aircraft.

For maximum tactical effect aircraft should be employed en masse, concentrated in time and space, against targets of the highest tactical importance.

For example, from the equation, with an of 0. 7, a rocket flying at Mach 0. 85 ( which most aircraft cruise at ) with an exhaust velocity of Mach 10, would have a predicted overall energy efficiency of 5. 9 %, whereas a conventional, modern, air-breathing jet engine achieves closer to 35 % efficiency.

For example: stakeholders withdrawing during a project may endanger funding of the project ; confidential information may be stolen by employees even within a closed network ; lightning striking an aircraft during takeoff may make all people on board immediate casualties.

For the first time in history, all nonemergency civilian aircraft in the United States and several other countries including Canada were immediately grounded, stranding tens of thousands of passengers across the world.

For efficiency of operations, some ATC operations will routinely provide " pop-up " IFR clearances for aircraft operating VFR, but that are arriving at an airport that does not meet VMC requirements.

For the occasion on which everyone already knows everyone else and the host wishes them to meet one or a few honored newcomers, then the `` open house '' system is advantageous because the honored guests are fixed connective points and the drifting guests make and break connections at the door.

For this change is not a change from one positive position to another, but a change from order and truth to disorder and negation.

For paradigmatic history `` breaks '' rather than unfolds precisely when the movement is from order to disorder, and not from one order to a new order.

For what we propose, however, a psychoanalyst is not necessary, even though one aim is to enable the reader to get beneath his own defenses -- his defenses of himself to himself.

For a freshman Congressman to read political Lessons to graybeard Democrats was poor policy for one who needed to make friends.

For this reason, then, poetry tends to weaken the power of control, the reason, because it tempts one to indulge his passions, and even the best of men, he maintains, may be corrupted by this subtle influence.

For one thing, Aristotle mentions that plays may corrupt the audience.

For by now the original cause of the quarrel, Philip's seizure of Gascony, was only one strand in the spider web of French interests that overlay all western Europe and that had been so well and closely spun that the lightest movement could set it trembling from one end to the other.

In his recent book, Hurray For Anything ( 1957 ), one of the most important short poems -- and it is the title poem for one of the long jazz arrangements -- is written for recital with jazz.
