The primary TACAN marshal fix is the _____ degree radial relative to the expected final bearing.

The marshal fix uses a radial opposite to the inbound final bearing. This 180-degree offset places the fix on the outbound side from the TACAN, giving a stable, unambiguous reference from which to align to the final approach. In other words, the primary marshal fix is on the radial that is 180 degrees away from the expected final bearing. For example, if the final approach course is 360 degrees, the marshal fix is on the 180-degree radial. Radials not opposite to the inbound course don’t provide the intended intercept geometry, so they’re not correct.
