3.18.4.13 FM HOME Mode. The FM homing (Figure 3-31) is engaged by selecting the FM HOME switch on the pilot’s VSI/HSI mode selector and the NAV switch on the pilot’s CIS mode selector. Selecting FM homing on the VSI/HSI mode selector directs FM homing signals only to the VSI. Other NAV modes will be retained on the HSI if previously selected. During the FM HOME mode, the CISP processes the lateral deviation and .ag signals dis-played on the pilot’s VSI in addition to the roll angle input from the attitude gyro. The CISP .lters and dampens the FM homing deviation signals and provides cyclic roll com-mands to aid the pilot in homing on a radio station selected on the COM 1 communications receiver. When properly followed, the roll commands result in not more than two overshoot heading changes before maintaining a tracking error not to go over 3°. The CISP will revert to the heading mode whenever the lateral deviation rate is over 1.5°/ sec for a period of over 1 second. The CISP will cause the CIS mode selector HDG switch ON legend to light, and remain in the heading mode until the FM mode or some other mode is manually selected. Concurrent VOR and FM, TACAN or concurrent DPLR and FM mode inputs will be considered an FM mode input to the CISP.
3.19.4.14 TURN RATE Select. The turn rate gyro se-lection provides each pilot the option of having his VSI display his own turn rate gyro signal (NORM operation) or of having the other pilot’s turn rate gyro signal displayed (ALTR operation). The turn rate gyro selection is indepen-dent of the navigation modes selected by the top row of switches and is independent of which turn rate gyro the other pilot has selected. The NORM selection connects each pilot’s VSI to his own turn rate gyro. The selection of NORM or ALTR operation is indicated by lighting the respective legend on the TURN RATE selector switch. The lamp power to the indicator legends is controlled through a relay so that the NORM legend is lit in case the mode selector logic or lamp drivers fail. Sequential opera-tion of the TURN RATE switch alternates the rate gyro connected to the VSI.
3.18.4.15 CRS HDG Select. The CRS HDG switch on the mode selector provides for either the pilot’s or the co-pilot’s course selector (CRS) to be connected to the navi-gation receiver, and for concurrent connection of the same pilot’s HSI course and heading information to the com-mand instrument system processor. The CRS resolver is normally connected to the pilot’s HSI until selected by the copilot on his mode selector. CRS HDG control is trans-ferred by pressing the CRS HDG switch. The pilot having the CRS HDG control is indicated by lighting of either the PLT or the CPLT legend on each mode selector. When power is .rst applied to the mode selector, the pilot’s po-sition is automatically selected. The CRS HDG selection is independent of the navigation modes selected by the top row of switches.
3.19.4.16 VERT GYRO Select. The vertical gyro se-lection provides each pilot the option of having his VSI display his own vertical gyro attitude (NORM operation), or of having the other pilot’s vertical gyro attitude dis-played (ALTR operation). The vertical gyro selection is independent of the navigation modes selected by the top row of switches and is independent of which vertical gyro the other pilot has selected. Each pilot’s VSI is normally connected to his own vertical gyro. The selection of NORM or ALTR operation is indicated by lighting the respective legend on the VERT GYRO selector switch. The lamp power to the indicator legends is controlled through a relay so that the NORM legend is lit in case the mode selector logic or lamp drivers fail. Sequential opera-tion of the VERT GYRO switch alternates the vertical gyro connected to the VSI.
3.19.4.17 No. 2 Bearing Select. The HSI number 2 bearing pointer selection allows the option of either the LF/ADF bearing or the VOR bearing to a selected station. The ADF/VOR selection is independent of the navigation modes selected by the top row of switches, and either pilot selects ADF or VOR, independent of the other pilot’s se-lection. The number 2 bearing pointer is normally con-nected to the LF/ADF bearing output. The selection of ei-ther ADF or either VOR or TACAN bearing is indicated by lighting of the respective legend on the selector switch. The lamp power to the indicator legends is controlled through a relay, so that the ADF legend is lit in case the mode selec-tor logic or lamp drivers fail. Sequential operation of the ADF/VOR switch alternates the bearing source connected to the No. 2 bearing pointer between ADF and VOR or TACAN.
