Final answer:
When engaging hover hold using cyclic trim beeper below 60 knots, the two modes that will capture on FD/DCP are pitch attitude mode and bank angle mode.
Step-by-step explanation:
When engaging hover hold using the cyclic trim beeper below 60 knots, two modes that will capture on the Flight Director (FD) / Director Channel Panel (DCP) are the pitch attitude mode and the bank angle mode. When engaging hover hold using the cyclic trim beeper in a helicopter below 60 knots, the two modes that will capture on the Flight Director/Display Control Panel (FD/DCP) are typically altitude hold and heading hold.
These modes assist the pilot by maintaining the current altitude and heading, allowing for a more manageable and stable hover. Depending on the aircraft's avionics system, when the pilot activates the cyclic trim beeper, the autopilot system takes input from various sensors and engages these modes to lessen the pilot's workload during low-speed precision maneuvers.
