True Heading of the navigation system, from 0 to 359.99 degrees, using 1
decimal place.
The character ‘T’ is output by the navigation system to represent that the
heading is to true north. Grid north and magnetic north are not output.
Roll of the navigation system, measured in degrees, with leading sign, leading
0’s where needed and 1 decimal place. Positive values mean that the left side
is up.
Roll of the navigation system, measured in degrees, with leading sign, leading
0’s where needed and 1 decimal place. Positive values mean that the left side
is up.
Pitch of the navigation system, measured in degrees, with leading sign, leading
0’s where needed and 1 decimal place. Positive values mean that the front is
up.
X-axis angular rate (roll rate) of the navigation system, measured in degrees/
second, with leading sign, leading 0’s where needed and 2 decimal places.
Positive values mean that the left side is moving up.
Lateral angular rate (pitch rate) of the navigation system, measured in degrees/
second, with leading sign, leading 0’s where needed and 2 decimal places.
Positive values mean that the front is moving up.
