Attitudes and Movements lesson. Movements: are the motions , called roll, pitch, and yaw that result in changes of attitudes. Objectives of the lesson Knowing the range of attitude use in normal flight. Knowing the movement necessary to produce and maintain desired attitude.
Learn yaw and how to control it. This basic principles that we need to learn, everything depends on it climb, descent, turn, cruise attitude and straight-and-level flight. Horizon in cruise attitude The primary visual reference used is usually the appearance of the natural horizon or the ratio of visible sky to ground, when you are looking straight ahead. The line of the dashboard are around three finger wide from the horizon line. To maintain the cruise attitude keep the horizon at the proper location in the windscreen.
The wings remain parallel to the horizon. Instruments indications in cruise attitude. The attitude of flight may be broken down in two groups: Pitch attitudes: any attitudes of the nose of the aircraft above or below the reference datum horizon. Bank attitudes: any attitudes of the wings of the aircraft when inclined relative to the datum. Pitch attitudes Pitching movement: Are produced and controlled by the elevators. This movement is used to achieve pitch attitudes.
These attitudes are maintained by use of elevator. The elevators are controlled by the movement of the control column forward or backward. Movement about the lateral axis.
It may even be considered an advantage to be able to see the instrument horizon line at all times since the indicated direction for recovery will always be obvious, whereas in the more common alternative it may move out of sight at extreme attitudes. Although the psychology of the two displays differs fundamentally in the portrayal of bank angle, neither presentation has historically been shown or widely claimed to be superior to the other, provided that the pilots have received their basic instrument flying training and proceeded through a flying career on aircraft equipped with similar instrumentation.
However effective aircraft control has sometimes been lost using both types because of confusion in attempting to suddenly interpret aircraft attitude from a depiction which is beyond the normally-experienced range. This is most often found in the commercial air transport context when an abnormal bank angle has developed slowly and without pilot awareness during instrument flying conditions. In general aviation , a similar confusion may arise when a VFR -rated pilot ends up attempting to maintain control of their aircraft after entering IMC ; however, in this case, awareness of abnormal attitude is more likely to be progressive than sudden, since the loss of a previous visual horizon is likely to have been noted as a significant precursor to at least potential control difficulty.
This is an important concept because it requires the pilot to develop a pictorial sense of this natural horizon. Figure Make flight training easier, less expensive, and more enjoyable.
