When using the collective trim beeper to increase or decrease altitude, the altitude will change at a rate of 4 fps for the first 4 seconds. After 5 seconds, the altitude will change at a rate of 16 fps. Holding the collective trim beeper up or down for more than 5 seconds changes the reference altitude by approximately 1000 fpm.
When HDG is not engaged with a coupled FD, the collective trim beeper may be used to establish a standard rate turn.
COM GUARD:
Sets the COM 2 (AN/ARC-231 - 2) radio to 243.000 MHz (UHF guard frequency) and also sets the COM 3 (AN/ARC-231 - 3) radio to 121.500 MHz (VHF guard frequency)
NORM: Placing the switch back to NORM sets both radios back to the previous band and frequency.
Immunizations: Medical restriction from flying duty will be for a minimum period of 12 hours following any immunization. If any type of reaction occurs, local or systemic, the aviator remains restricted from flying duties until cleared by a flight surgeon or APA
Descent below MDA is not authorized until sufficient visual reference with the runway environment has been established and the aircraft is in a position to execute a safe landing.
Descent below DA/DH is not authorized until sufficient visual reference with the runway environment has been established
By either using the P-Sync Knob or using the Cyclic Trim Beeper.
While the IAS mode is coupled, the IAS reference is capable of being adjusted five knots per second or in one knot increments upward by moving the cyclic TRIM beeper switch forward.
The pilot is responsible to ensure that the reference conditions set on the FD/DCP are achievable within the aircraft engine limits and ambient conditions and to monitor torque, TGT and NG in coupled flight.
1.5 mile radius for category “B”.
If no holding pattern is charted and holding instructions have not been issued, the pilot should ask ATC for holding instructions prior to reaching the fix. This procedure will eliminate the possibility of an aircraft entering a holding pattern other than that desired by ATC. If unable to obtain holding instructions prior to reaching the fix (due to frequency congestion, stuck microphone, etc.), then enter a standard pattern on the course on which the aircraft approached the fix and request further clearance as soon as possible. In this event, the altitude/flight level of the aircraft at the clearance limit will be protected so that separation will be provided as required.
