T-45A UJPT & E2-C2 INav-10
Flight Planning (En Route)
Figure 3 shows the first section of the DD Form 175.
The FAA “assumes” that all aircraft have VOR as their primary navigation means. Therefore, if the aircraft
VOR was inoperative, the T-45 would revert to a /P. However, if VOR and IFF were both inoperative, the
T-45 could revert to /M. “DME” indicates that the aircraft can receive VOR and the VOR DME at those
VOR stations that are not “VORTACs” but do have DME.
NOTE: Do not use a letter after the aircraft designation to denote the aircraft model. The aircraft model
could be confused for the transponder code.
