HSI CONTROL PANEL
The HSI control panel, located on the pilot instrument panel, has three rotary switches that control what system data will be presented on the HSI and RMI. |
| CONTROL / INDICATOR | FUNCTION |
| 1. BRG PTR 1 switch [M] DPLR | Doppler bearing information is presented on HSI bearing pointer number 1. |
| ADF | ADF bearing information is presented on HSI bearing pointer number 1. |
| VOR | VOR bearing information is presented on HSI bearing pointer number 1 and VOR bearing is presented on gunner RMI bearing pointer number 2. |
| 2. BRG PTR 2 switch ADF | ADF bearing information is presented on HSI bearing pointer number 2 and ADF bearing is presented on gunner RMI ADF bearing pointer number 1. |
| VOR | VOR bearing information is presented on HSI bearing pointer number 2 and VOR bearing information is presented on gunner RMI bearing pointer number 2. |
| 3. COURSE switch VOR | Presents selected VOR / LOC station displacement signal information to the HSI course deviation bar and glideslope deviation pointer and VOR / LOC signal information is also presented to the ADI course bar. |
| FM HOME | Presents FM homing course and glideslope deviation displacement information to both the ADI and HSI pointers. |
| [ M ] DPLR | Presents selected doppler coordinates course deviation to the HSI course deviation bar, doppler signal validity information to the navigation flag of HSI, and displays range to selected destination in range window of HSI. |
