Note 1: ID 4 may not be used with Category 13 (I/O Discrete Type) ID’s 2, or 3. This is due to a conflict with the validity
discrete. ID 0 may be used instead with the Validity discrete left unconnected. Also, ID 4 are intended to be used with
helicopter types that do not have the tail strike functionality (currently the MD-900 only).
Note 2: ID 128 may only be used in conjunction with Category 11 (Magnetic Heading) ID 2.
