(b) Push the line select key adjacent to the "AFS" indication.

4. Procedure
Subtask 22-96-00-740-050-A ** ON A/C NOT FOR ALL

A. Read the HPP of the FACs and the FMGCs.

NOTE: The "PIN PROGCONFIG" indication is the name of the HPP on the MCDU.

B. Decode the HPP of the FACs and FMGCs.

The HPP is shown as a hexadecimal code in which each digit can have 16 values (0 thru F). The digit rank of the HPP code is readable from the left (first digit) to the right (last digit).
The converted code of the HPP code is a binary code.
In the HPP code, each digit has four bits which are readable from the right (right-most bit) to the left (left-most bit). Each bit can have two values: 0 or 1.

	Binary
Hexadecimal digit	Left-most bit			Right-most bit
0	0	0	0	0
1	0	0	0	1
2	0	0	1	0
3	0	0	1	1
4	0	1	0	0
5	0	1	0	1
