(b)  
The test routine numbers and Parameters (P) are binary coded with the Most Significant Bit (MSB) on the left and the sign codes are word bits 16, 24, and 29. The output data block uses the standard AIM Sign/Status Matrix (SSM) code. Test parameter bits and word assignments are as follows: 1) P1, bits 17 through 24 of word 1 2) P2, bits 25 through 29 of word 1 (reserved) 3) P3, bits 9 through 16 of word 2 4) P4, bits 17 through 24 of word 2 5) P5, bits 25 through 29 of word 2 6) P6, bits 9 through 16 of word 3 7) P7, bits 17 through 24 of word 3 8) P8, bits 25 through 29 of word 3 9) P9, bits 9 through 16 of word 4 10) P10, bits 17 through 24 of word 4 11) P11, bits 25 through 29 of word 4

 (15) MCDP Input Test Data Block (Fig. 15)
 (a)  The MCDP INPUT test data block sends the test results back to the MCDP. The data block consists of eight 32-bit words with each word containing ARINC label 356 in word bits 1 through 8. The SSM code in bits 30 and 31 uses standard AIM data coding. Bit 32 checks parity. The specific bit definitions for each word are as follows: 1) Word one - bits 9 through 16 specify the number of words
 (always 8) in the data block. Bits 17 through 24 contains the test routine numbers from the MCDP. Bits 25 through 28 are spares. Bit 29 contains the test request wrap-around used during ground test entry functions.

 2)  Word Two - bits 9 through 27 contain the ground test comparison results. The results are discretes that indicate whether the following are within tolerance; left and right column null; left column forward and aft; right column forward and aft; control wheel null; left and right control wheel rotation; flap 0, 10, and 30 degree position, elevator detent. Bit 28 contains the test in progress status. Bit 29 contains the test valid status.
 3)  Word Three - Bits 9 through 27 contain Binary Numerical Representation (BNR) data. The BNR data indicates position-data in response to the test number sent in word two. Bits 25 through 29 are spares.
 4)  Words Four through Seven - Bits 9 through 29 are discrete data defining the test response conditions.
 5)  Word Eight - Bits 9 through 29 are spares.
