After interpreting pitch attitude by reference to the pitch instruments attitude indicator, altimeter, airspeed indicator, and vertical speed indicatorcyclic control adjustments are made to affect the desired pitch attitude. Altimeter error caused by nonstandard temperature The following example describes how fixation can occur. Archived from the original on 15 August Preface Field manual FM To determine the approximate bank angle, divide airspeed by 10 and add one-half of the result as shown in the following example.

The radio magnetic indicator RMI Figurepage is a navigational aid providing aircraft magnetic or directional gyro heading and very high frequency omnidirectional range VOR or automatic direction finder ADF bearing information.

When the aircraft yaws, or rotates about its vertical axis, a force is produced in the horizontal plane that, because of precession, causes the gyro and its gimbal to rotate about the gimbal axis.

Improper brake application may allow the airplane to creep after alignment; alignment with the nose wheel or tail wheel cocked may cause improper alignment on the runway. During level turns, the altimeter is primary for pitch and the airspeed indicator is primary for power Figurepage As flying speed is approached about 15 to 25 knots below takeoff speedsmoothly apply elevator control for the desired takeoff attitude on the attitude indicator about a mahual climb indication for most airplanes.

Other types of weather phenomena Stabilized constant airspeed climb A knob on the instrument allows rotation of the subdial and alignment of an indication of the outside air temperature with the pressure altitude being fild this alignment causes manua, instrument pointer to indicate TAS on the subdial.

The rate of movement of the altimeter needle is as important as its direction of movement for maintaining level flight without the use of the attitude indicator.

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.

Adjust pitch attitude smoothly to avoid overcontrolling.

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. Rotary Wing Instrument Flight Maneuvers required because the helicopter tends to pitch up as collective pitch angle is increased. Absolute altitude is the altitude above the surface or terrain where the aircraft is flying, also called above ground level AGL.

Therefore, the aviator must convert the TH, as plotted on the navigation chart, to a magnetic heading MH by which to steer, using the compass. Determining radius of action, part II An increase in power causes the helicopter to start climbing, and only slight back cyclic pressure is required to change from level to climb attitude.

The altimeter is primary for pitch control, and the turn needle is primary for bank control. When the altimeter indicates 5, feet, the true altitude is also 5, feet.

An altimeter is an aneroid barometer that measures the absolute pressure of ambient air and displays that absolute pressure in terms of feet or meters above a selected pressure level. Ground speed is the speed of an aircraft relative to the surface of the earth.

Because the altitude should remain constant when the airplane is in level flight, any deviation from the desired altitude signals the need for a pitch change. Magnetic north MN changes in small amounts each year.

If, while flying on this easterly heading, the aircraft decelerates, inertia causes the weight to move ahead and the card rotates toward the south until the speed again stabilizes. Chapter 2 indicator during turns in each mznual, note corrected deflections.

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.

Transition to sustained air traffic control operations When making similar turns from a westerly direction, begin rollout at degrees for a turn north and degrees for a turn south.

Army helicopters including a summary of general crewmember tasks. The magnetic field pulls on the end of the magnet, causing the card to rotate toward the east. Vertical speed indicator
