Back course LOC approach 2.9.4.6.2
NOTE: The T-45A is not equipped with automatic reverse sensing
equipment which would provide a normal sensing display on the HSI
and ADI when executing a back course LOC. When flying a back
course LOC in this aircraft, the pilot will always experience reverse
sensing on the ADI and on HSI displays when the back course
inbound course to the field is selected. In this situation, to correct to
course, the pilot will have to “fly away” from the ADI azimuth
deviation bar and HSI CDI. An alternate procedure is to set the front
course into the HSI. This will induce a normal sensing display in the
HSI. Caution should be taken because the azimuth deviation bar on
the ADI will continue to display reverse sensing.
