  Chapter 5: Flight Instruments › Dynamic Pressure Type Instruments › Magnetic Compass Errors

  rule of thumb to correct for this leading error is to stop the turn 15° plus half of the latitude (i.e., if the airplane is being operated in a position around the 40° of latitude, the turn should be stopped ... prior to the desired heading). [Figure 5-20A] Southerly Turning Errors When turning in a southerly direction, the forces are such that the compass float assembly lags rather than leads. The result is a false southerly turn indication…

  Figure 8-36. Northerly and southerly turning errors. Southerly Turning Errors When turning in a southerly direction, the forces are such that the compass float assembly lags rather than leads. The result is a false southerly turn indication. The compass ... float assembly, should be allowed to pass the desired heading prior to stopping the turn. As with the northerly error, this error is amplified with the proximity to either magnetic pole. To correct this lagging error, the aircraft should…

  Chapter 8: Helicopter Attitude Instrument Flying › Instrument Flight › Instrument Cross-Check

  However, with familiarity and practice, the instrument cross-check reveals definite trends during specific flight conditions. These trends help a pilot control the helicopter as it makes a transition from one flight condition to another. When full concentration is applied ... single instrument, a problem called fixation is encountered. This results from a natural human inclination to observe a specific instrument carefully and accurately, often to the exclusion of other instruments. Fixation on a single instrument usually results in poor control…

  Chapter 7, Section II: Airplane Basic Flight Maneuvers › Common Errors › Turns to Predetermined Headings

  Another error normally encountered during standard rate turns is inefficient or lack of adequate cross-checking. Pilots need to establish an aggressive cross-check in order to detect and eliminate all deviations from altitude, airspeed, and bank angle during ... maneuver. 3. Fixation is a major error associated with attitude instrument flying in general. Pilots training for their instrument rating tend to focus on what they perceive to be the most important task at hand and abandon their cross-check…

  Chapter 8: Flight Instruments › Instrument Check › Remote Indicating Compass

  number of designs of the remote indicating compass; therefore, only the basic features of the system are covered here. Instrument pilots must become familiar with the characteristics of the equipment in their aircraft. As instrument panels become more crowded ... pilot’s available scan time is reduced by a heavier flight deck workload, instrument manufacturers have worked toward combining instruments. One good example of this is the RMI in Figure 8-30. The compass card is driven by signals from…
