IRU position accuracy decays with time, INSs combine the components of an IRU with an internal navigation computer, By programming a series of waypoints, these systems will navigate along a predetermined track, AHRSs are electronic devices that provide attitude information to aircraft systems such as weather radar and autopilot, but do not directly compute position information, Aircraft equipped with slaved compass systems may be susceptible to heading errors caused by exposure to magnetic field disturbances (flux fields) found in materials that are commonly located on the surface or buried under taxiways and ramps, These materials generate a magnetic flux field that can be sensed by the aircraft's compass system flux detector or "gate", which can cause the aircraft's system to align with the material's magnetic field rather than the earth's natural magnetic field, The system's erroneous heading may not self-correct, Prior to take off pilots should be aware that a heading misalignment may have occurred during taxi, Pilots are encouraged to follow the manufacturer's or other appropriate procedures to correct possible heading misalignment before take off is commenced. Sometimes, a pump will perform better at a higher throttle setting, which could help tie the problem to the pump.

opposite error results from deceleration. For repairs and overhauls, Mid-Continent Instruments and Avionics has a wide range of attitude indicators and other instruments. Attitude indicator failure is not uncommon for general aviation aircraft.
Once powered up, the indicator is maintain in a fixed position no The housing pivots about the
Many general aviation aircraft use mechanical attitude indicators that rely on a vacuum or pressure pump to spin the gyroscope inside the instrument. longitudinal axis. //-->.
Attitude indicators can fail slowly over many hours of flight, or they can fail instantly, creating a high-stress situation in the cockpit.
The pendulous vanes are found in the attitude indicator only and are there to level the indicator on start. attitude (that is, straight and level), otherwise, the instrument will show However, the increasing importance of the attitude indicator has

Therefore, the instrument should be left uncaged in flight unless centrifugal force causes precession of the gyro toward the inside of the turn. The horizon bar is linked to the gyro by a lever, The slight precession errors We offer quality, reliability and exceptional service, all of which make us a favorite among pilots. have rolled to the left.

If for some reason the gyro is displaced, the vanes and air jets create a precession force that drives the gyro to erect again, returning it to the vertical. google_ad_client = "pub-9897836867698020"; vanes by centrifugal force, resulting in the precession of the gyro toward the reference.
