Which orientation during landing operations is most affected by the forward radar blind spot?

Answer: A — Bow-on approach

Radars on a carrier have a forward blind spot caused by the hull and deck structures blocking energy in front of the ship. When landing with the ship’s bow facing the aircraft, the aircraft sits directly in that blocked region, so the radar may not detect it until it is very close. In other orientations—stern-on, side-on, or overhead—the aircraft is seen from angles where the radar has a clearer line of sight and the hull blocks the view less. Therefore, bow-on approaches are the ones most affected by the forward radar blind spot.
