  Flight level - Wikipedia, the free encyclopedia
Flight levels solve this problem by defining altitudes based on a standard pressure of 1013.2 mbar (the equivalent setting of 29.92 inHg is used in U.S. and Canada).
Flight levels are then assigned a number, which is this nominal altitude ("pressure altitude") in feet, divided by 100.
Flight levels are not used close to the ground, for perhaps obvious reasons — the true height of an aircraft relative to an object on the ground needs to be known.

 Online Education - Introduction To Flight Testing - Acceleration / Deceleration
Level flight accelerations and decelerations (accels - decels.) are also used to determine the stability of the airplane with respect to speed.
Level flight accels and decels for stability purposes are usually repeated at the same flight condition, but at different values of center of gravity position to identify the "neutral point" of the airplane.
During a level flight acceleration we have forced the second term in the equation to be zero by flying at constant altitude (zero rate of climb).

 Aircraft flight mechanics - Wikipedia, the free encyclopedia
In steady, level flight, an aircraft can be considered as being acted on by four forces in equilibrium: lift, weight, thrust, and drag.
Very roughly, in straight and level flight, lift can be assumed equal to weight and thrust equal to drag.
Aircraft that need control at extreme angles of attack are sometimes fitted with a canard configuration, in which pitching movement is created using a forward foreplane (roughly level with the cockpit).

 Performance – Class 1 Airplane Motions
Although straight and level flight may occur only over a small section of the total flight, it is very important since it is usually considered the standard condition in the design of an airplane.
For straight and level flight, the flight path is horizontal to the Earth's surface and, for simplicity, it is assumed that the thrust always acts along this horizontal plane.
Thus, at low speeds, to fly straight and level, the airplane angle of attack is large whereas for high speeds the airplane angle of attack is small.

 Resource Detail - FDAI Database
For the first roundtrip flight from Basle-Mulhouse, the pilot in the left seat was the designated captain, and he had the controls.
At 12:44, the aircraft left this level flight altitude and descended toward the aerodome, which was identified visually.
Throughout the whole descent and at the start of level flight made with engines set to flight idle, the aircraft decelerated and its pitch-up increased during the last 25 sec.

 Level H - Flight time and docility Vs meat quality and feedlot performance   (Site not responding. Last check: 2007-09-30)
The test used by the CRC for Cattle and Beef Quality is an animal’s flight time, the electronically recorded time taken for an animal to cover a fixed distance (1.5 to 2 m) after leaving a weighing crush, with low flight times (fast exit from the crush) indicating animals with poor temperaments (see Figure 1).
Experiments done on three groups of animals (~200 animals per group) showed that a single measure of flight time recorded at weaning had a significant effect on weight loss during that long-distance transport and for the initial recovery period, but no effect on subsequent weight gains when animals were grazed at pasture under extensive management.
Flight time was found to be a useful predictor not only of individual animals that lost weight during transport but also of how well groups of animals fared during such transit.

 Straight and level Flight   (Site not responding. Last check: 2007-09-30)
The pitch attitude for level flight (constant altitude) is usually obtained by selecting some portion of the airplane's nose as a reference point, and then keeping that point in a fixed position relative to the horizon.
Straight flight (laterally level flight) may also be accomplished by visually checking the relationship of the airplane's wingtips with the horizon.
In straight and level flight the wingtips can be used for both estimating the airplane's laterally level attitude or bank, and to a lesser degree, its pitch attitude.

 Instrument Flight
For example, one manual's suggested procedure for leveling off from a climb is: note the altimeter; lower the nose on the attitude indicator; check for increasing airspeed on the airspeed indicator; check for constant heading on the heading indicator (the heading often swings to the right on level-off).
In instrument flight turns are typically made at a rate of three degrees per second or less; steeper turns are considered dangerous.
If the symptoms of vertigo appear and the instruments confirm the aircraft is in straight-and-level flight, the pilot should hold the aircraft's attitude for a minute or two allowing the disorientation to pass.

 requested flight level   (Site not responding. Last check: 2007-09-30)
This is the flight level at which they would like to operate.
Flights travelling predominantly westbound file even numbered flight levels (180, 200, 220, 240 etc) and the opposite is true for eastbound.
However, it is not always possible to allocate the level requested in the flight plan and pilots often alter their requests once airborne.

 Certifying Level 3   (Site not responding. Last check: 2007-09-30)
Level 3 certification is a serious proposition and not taken lightly by the Tripoli Rocketry Association Inc. Level 3 projects are typically large, heavy and complex.
When attempting a level 3 flight, the multi-part form and the documentation submitted to TAP should be made available to the launch RSO.
The flight must be witnessed by a member of TAP ONLY and only a TAP member can sign off on the flight granting level 3 certification status.

When it is not being used at flight altitudes above flight level 250, the oxygen mask must be kept in condition for ready use and located so as to be within the immediate reach of the flight crewmember while at his duty station.
(4) Before the takeoff of a flight, each flight crewmember shall personally preflight his oxygen equipment to insure that the oxygen mask is functioning, fitted properly, and connected to appropriate supply terminals, and that the oxygen supply and pressure are adequate for use.
Before flight is conducted above flight level 250, a crewmember shall instruct the passengers on the necessity of using oxygen in the event of cabin depressurization and shall point out to them the location and demonstrate the use of the oxygen-dispensing equipment.

 Flight Scheduling: Progress
For example, r2(f) and x2(f) are the requested flight level and the actual flight level, respectively, for flight f.
With regard to the departure level, the integers 1 through 4 correspond with outbound levels (these are the even altitudes described in the "Background and Motivation" section).
Intuitively, a flight cannot take off before it has requested to take off, and by convention the scheduling algorithm will not allow a flight to be delayed by more than twenty minutes.

 AOPA Online - Flight Training Article   (Site not responding. Last check: 2007-09-30)
In a nutshell, integrated flight training is the process of teaching pilots, from the very first lesson, to fly by both visual references (VR) and instrument references (IR), and to build a perceptive connection between the two.
With this in mind, and depending on the airplane you fly, you may be able to limit your standard aircraft configurations to as few as two airspeeds: one for cruise and cruise descents, and another, slower speed for takeoffs and landings.
The objective is to decipher the instruments in a nonstandard flight regime, apply the proper control inputs to regain control, and return to normal, level flight.

 FlightSim.Com Review: Level-D 767
When the Flight Director (FD) switch is engaged, guidance from the FCCs is annunciated on the EADI in the form of 'command' bars, which can either be used to guide manual flight, or automatic flight if one of the autopilots is engaged, with the MCP controlling the FD mode.
All the possible MCP modes are implemented, including flight level change, vertical speed, vertical and horizontal navigation under command of the FMC, heading select and hold, altitude hold, localiser approach, backcourse and ILS approach.
One of the things that differentiates the Level D unit from other 'fully featured' FMCs is that it actually does have the majority of the features implemented and you will have to get to know the control display unit (CDU) extremely well, as the plane can't easily be flown without a good understanding of it.
