FORMAT B (52 BYTE ASCII STRING)
BYTE DESCRIPTION
1 STX (ASCII code 02H)
2 Unit of Measure
G = .1 gallon
I = .1 imperial gallon
L = 1 liter
K = 1 kilogram
B = 1 pound
3-8 Total Fuel Remaining
ASCII-coded decimal format (least significant digit is tenths), LSB first
Example:
A fuel remaining value of 543.2 would be sent as “2.3450” (32H, 2EH, 33H, 34H, 35H,
30H).
9 Total Fuel Remaining Checksum
Break each decimal value into BCD representation. Using BCD arithmetic, sum the 4
BCD values and convert the lower-order BCD digit to an ASCII coded numeric digit.
Example:
The checksum for a value of 543.2 would be “4” (34H).
10-15 Total Fuel Flow Rate
ASCII-coded decimal format as for Total Fuel Remaining.
16 Total Fuel Flow Rate Checksum
Sum of fuel flow bytes computed as for Total Fuel Remaining.
17-22 Engine One Fuel Flow Rate
ASCII-coded decimal format as for Total Fuel Remaining
23 Engine One Fuel Flow Rate Checksum
Sum of Left Engine Fuel Flow Rate bytes computed as for Total Fuel Remaining
24-29 Engine Two Fuel Flow Rate
