NOTE 1: The following RT-300 part numbers meet ARINC 552 for the Auxiliary Output: 7001840 - 902, -906, -912, -916, -917, -918, -922, -926, -928, -932, -936, -937, and -938. Some RT- 200’s are also compatible, consult your Honeywell representative.

NOTE 2: This is the precision output from the R/T. Note the + and – signals are swapped to convert the –4mV to +4mV.

NOTE 3: The ALT-55 provides compromised EGPWS performance due to the average altitude tracking algorithm employed.
