Suggested inclusions in the Heatblur F-4E Manual

[450Devil]

Reference: TO 1F-4E-1 Flight Manual USAF Series F-4E Aircraft page 4-12

These are suggestion only:

1. In the Abbreviations section of the Heatblur F-4E Manual include BATH Best Available True Heading

2. Include in the manual a brief explanation of the accuracy of each type of INS alignment - Gyro Compass Alignment (full alignment) takes the longest to achieve but is the most accurate with a 3 nautical miles of error per hour of circular error probability (CEP) - BATH alignment take just over two minutes but has an expected 5 and a half miles of error per hour of CEP - Heading Memory Alignment (Stored Heading) take just over two minutes but has an expected 5 and a half miles of error per hour of CEP. 

3. Also a warning that BATH alignment should not be used when the aircraft is in a hangar, near any large metal objects (power carts, etc), or when the wings are not spread and locked. Gyro compass alignment should be used whenever the aircraft magnetic heading signal is unreliable.

The accuracies are already listed in the INS section I believe.
