Army helicopters including a summary of general crewmember tasks. In either instrument, a standard-rate turn is being made whenever the needle aligns with a doghouse-shaped mark. The Earth is a huge magnet surrounded by a magnetic field made up of invisible lines of flux. Adjust the attitude indicator, as appropriate.

Archived from the original on 15 August If further maual is required, an additional correction of one-half bar normally corrects any deviation from desired altitude.

If the turn is made with too shallow a bank angle, inertia is feld than gravity and the ball rolls upward to the outside of the turn. It shows the relationship between bank fiele and rate of yaw. Point in space approach In some installations, the azimuth card is a remote indicating compass; however, in others the heading must be checked occasionally against the magnetic compass and reset. The following example describes how fixation can occur. A small bank angle is indicated by a slow change of heading; a large bank angle is indicated by a rapid change.

Standard holding pattern—no wind Thread Tools Show Printable Version. Unless this publication states armmy, masculine nouns and pronouns do not refer exclusively to men. You may not post new threads. Rather than using a needle as an indicator, the gimbal moves a dial in which the rear view is of a symbolic aircraft. The appropriate operator or maintenance manual should be referenced to confirm which limit is accurate. Hold vertical speed constant until about 50 manaul above desired altitude.

As a result, their thickness changes as air pressure changes. Occasionally, the VSI may be slightly out of calibration, erroneously indicating a slight climb or descent dield the helicopter is actually in level flight. Attitude control is stressed in terms of pitch figurepagebank figurepagepower, and trim.

Emphasis on a single instrument, instead of all instruments necessary for attitude information, is an understandable fault during initial stages of training. Rotary Wing Instrument Flight Maneuvers to instrument references is necessary any time that disorientation occurs or when outside visual references become unreliable.

A turn coordinator does not sense changing feld attitudes of the aircraft. In addition to indicating airspeed, the airspeed indicator indirectly indicates helicopter pitch attitude.

Which instrument is primary for a particular maneuver should be considered in the context of the specific airplane, weather conditions, aviator experience, operational conditions, and other factors.

Although the amount of lead varies with the helicopter being flown and piloting technique, the most important factor is vertical speed. To center the ball, level the helicopter laterally by reference to other bank instruments and then center the ball with pedal trim. The New Wrmy Times.

Fieod glide-slope pointer indicates the relation of the aircraft to the glide slope. Adjust the pitch attitude to maintain altitude. The desired course is selected by rotating the course select pointer, in relation to the azimuth card, by means of the course select knob. A large and abrupt pitch change produces erratic needle movement and a reverse indication and introduces greater time delay before the needle stabilizes.

If available, the attitude indicator establishes desired pitch attitude.

To accomplish calibration, establish a standard-rate turn by referring to the turn-and-slip indicator. While holding the indicated rate of turn constant, note heading changes at second intervals. The Army Safety Program. Air traffic services and airspace information If the needle of the turn-and-slip indicator shows a deviation from the desired deflection, change the bank.

Dynamic pressure is the difference in ambient static air pressure and total, or ram, pressure caused by motion of the aircraft through the air. Find More Posts by wishtobflying. A graduated scale, called a card, is wrapped around the float and viewed through a glass window with a lubber line across the center of the glass.

In a turning autorotation, a standard-rate turn is maintained by reference to the needle of the turn-and-slip indicator. Encoding altimeter with a malfunction These lines leave the surface at the magnetic north pole and reenter at the magnetic South Pole.

If the instrument cannot be adjusted, consider the error when using the VSI for pitch control; for example, if the needle indicates a descent of FPM while in level flight, use this indication as the zero position.
