Radar screen

The radar screen presentation mode can be either B-scope or Tactical Mode (F-scope). The mode was selected by the system depending on mission phase and data from mission control (STRIL). In this simulation you can toggle manually between F-scope and B-scope modes with the KONTR switch on the radar control panel (this switch was in reality a test switch).

The radar has two distance ranges, 16 km and 40 km, and two sweep widths, 40 and 120. Antenna elevation can be adjusted, although it has no function in this simulation.

An artificial horizon is displayed on the screen when the radar is active or in standby mode. The gain (brightness) of the CRT screen and the illumination of the etched grid can be adjusted independently with dimmers on the Weapons control panel.

Radar control panel

The radar control panel is located on the left side wall of the cockpit. Only two of the switches are functional in this simulation.

The B-scope/F-scope toggle switch was in reality a test mode switch, but in this simulation we use it to manually select presentation mode.

Weapons control panel

The weapons control panel on the right side wall of the cockpit contains the radar master switch and dimmers for CRT gain (brightness) and for the grid and crossbars in the radarscope.

The FPLF switch selects whether the antenna should be gyro-stabilized (always horizontal) or fixed (moving with the aircraft).

Radar control handle

The radar control handle is a joystick located on the left side in the cockpit. It was used to control the cursor on the radar screen and to quick-select targeting modes and weapons. The control handle is not functional in this simulation.

The radar range select switch on the base of the radar control handle is used to select radar range.

Loadout configuration

Fig. 65 -  Loadout configuration panel

The weapons shown in the exterior model can be changed using the Loadout Configuration panel.

The 35J had 6 hardpoints for Sidewinders, IR/RR Falcons and air-to-air rockets. Air-to-ground rockets and free-fall bombs could also be fitted (never used AFAIK).

This simulation has 9 preset loadout configurations available, named J1 to J9. You can choose between three different Sidewinder models for the missile presets.

Selecting weapons

The Weapons Indicator to the left of the gunsight shows which weapon is currently selected. Indicator lights R and I will be disabled if RR or IR targeting missiles are not mounted.

Gunsight

The S-7B3/31 reflector gunsight in J 35J was integrated with the avionics and radar systems, and could be used in either radar-aided or optical mode. It provided aiming information for A/A missiles in radar-aided mode, and for the cannon and A/G missiles in optical mode.

This simulation only includes the optical mode with gyro aiming (diamonds and pipper). The gunsight will be activated if the weapons selector is set to either AKAN (cannon) or any of the missile launch modes. If cannons are selected the gunsight will use gyro aided aiming. If missiles are selected the reticule will be static.

The targeting range (radius of the gunsight reticle) can be adjusted with the knob on the right side of the gunsight assembly.

Since targeting is not implemented in this simulation, the gunsight has no real function.
