  6. Aeronautical Information Manual Explanation of Changes (Change 1) Effective: 26 Jul 12 This change explains why slaved compass systems may be susceptible to heading errors on the ground and alerts pilots to the fact that the system’s erroneous heading may not self-correct. It also offers mitigation strategies to avoid a possible heading misalignment at takeoff. Para 1−1−7 d

  7. d. 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.

  22. Will selected course take you toward or away from station? ORIENTATION What is your position (radial)?

  23. ENABLING LEARNING OBJECTIVE E

  24. Intercept the 190 degree radial inbound. 1. Locate radial to be intercepted (190). 2. Convert to course. 3. Rotate course selector knob until point of course selector shows new course (010°). 4. Turn TOWARD the course deviation indicator until course selector is at the 45° index. 5. As deviation bar centers, turn to new course.

  25. Intercept the 210 degree radial inbound EXPEDITE. 1. Locate radial to be intercepted (210). 2. Convert to course. 3. Rotate course selector knob until point of course selector points to new course (030°). 4. Turn TOWARD course deviation indicator until course selector is at the 90° index. 5. As deviation bar centers, turn to new course.

  26. Intercept the 025 degree Radial Outbound 1. Locate radial / course to be intercepted (025°). 2. Rotate course selector knob until point of course selector shows new course (025°). 3. Turn TOWARD course deviation indicator until course selector is at the 45° index. 4. As deviation bar centers, turn to new course.

HSI Deviation Scale - 0.3 Nm + 10o - 5 Nm -1 Nm - 2 1/2o +5 Nm + 0.3 Nm + 2 1/2o -10o + 1 Nm • LOC (Localizer) = + 2 ½ degrees • VOR = + 10 degrees • GPS = • Enroute = + 5 Nm* • Terminal Area = + 1 Nm • Approach = + 0.3 Nm * Flight line IP’s usually select 2 Nm; however this is for RNP (Required Navigation Performance) certification which the A/C is NOT certified for.

  37. Bendix-King KI-825 Electronic Horizontal Situation Indicator (EHSI) As of: Oct 2013 6 IFR TH-67’s are equipped with the KI-825. Installations are being completed when aircraft are in phased maintenance. (This is NOT progressing quickly as from Jan 2013 – Oct 2013 only one KI-825 was installed) Simulators will be updated when 50% of our fleet has KI-825’s installed. (Circa year 2033) Our Fleet: 65 IFR TH-67’s For more info: http://www.seaerospace.com/king/kinggra/ki825pg.pdf
