Fixations are likely during trim changes, attitude changes, gear and flap retractions, and power changes; after checking an instrument or fjeld a control, continue the cross-check and note the effect of the control during the next cross-check sequence.

If the helicopter is properly trimmed and the rotor tilts, a turn begins. The primary instrument is one that gives the most pertinent information for a particular maneuver and is usually fielx at a constant indication.

When the aircraft is approaching the descending airspeed, the airspeed indicator becomes primary for pitch and the torque meter is primary for power. All three receive the pressures that they Contents measure from the aircraft pitot-static system.

C-6 30 April FM AR requires a magnetic compass for all flights. 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.

Relax the control pressures carefully, continuing to cross-check, because changing airspeed will cause changes in the effectiveness of a given control pressure. The HSI shows the fixed aircraft symbol and course deviation bar to display relative position to the selected course.

Briefing record block explanation If you do manage to create an “e course” of that sylabus, they would probably be intrested in buying it too!! Because of precession error, the attitude indicator temporarily shows a slight error, correctable by quick reference to the other flight instruments.

For turbine-powered helicopters, power is observed on the torque gauge. The database typically includes information on navigation aids, airports, runways, waypoints, routes, airways, intersections, departures, arrivals, and instrument approaches.

The attitude indicator was originally referred to as an artificial horizon and later as a gyro horizon.

An ITO may be accomplished from a hover or the ground as visibility restrictions permit. In aerial navigation, the difference between true and magnetic directions is called variation. Navigation instruments on a UH This instrument Figure combines the magnetic compass with navigation signals and a glide slope.

Mounted in the instrument case is a small symbolic aircraft, which appears to fly relative to the horizon. Other types of weather phenomena Temperature correction chart height in feet An FMS normally contains an internal navigation database with either regional or worldwide coverage.

The initial movement of the horizon bar should not exceed one bar width high or low. Adjust power to maintain desired airspeed. In other projects Wikimedia Commons. Instantaneous vertical speed indicator Note any up or down trend of the needle from zero and apply a very light corrective elevator pressure.

If the rotor is laterally level and torque is properly compensated for by pedal pressure, the ball remains in the center. With a constant power setting, a normal cross-check should be satisfactory. The bibliography lists field manuals by new number followed armt old number. Conversely, by decreasing power and holding airspeed constant, the helicopter descends. Aircrew manuals warn that airspeed indications should be considered unreliable when forward airspeed is less than 25 to 40 knots depending upon aircraft size and weight.

Small pitch changes, smoothly executed, result in an immediate change of fisld.

The four types are indicated, calibrated, equivalent, and true. Helicopter control is the result of accurately interpreting and translating flight instrument readings into correct control responses. At a constant altitude and stabilized airspeed, pitch attitude is approximately level Figurepage To fly a gm by instrument reference, knowledge of the approximate power settings is required for fiwld particular helicopter in various load configurations and flight conditions.

This publication has been reviewed for operations security considerations.

The torque meter is primary for power control while airspeed is changing. As power is applied and the helicopter becomes airborne, maintain desired heading with the pedals and use cyclic to maintain desired ITO pitch attitude. To maintain a straight-and-level flight path, keep the wings of the airplane level with the horizon assuming that the airplane is in coordinated flight.

Stabilized left climbing turn, constant airspeed FM Distribution limited to US government agencies.
