F16 HOTAS Information

1.) FLCS Stick

2. TQS Throttle

Switches on the throttle and stick allow hands-on interface with the fire control system and perform various weapons delivery functions. Each of these switches is described in the appropriate throttle/stick paragraphs.

Some of these switches are multipurpose and their function at any one time depends upon such variables as master mode, AG weapons delivery mode/sighting option, and location of the sensor of interest (SOI).

The SOI is that sensor for which the hands-on controls are currently active. Similar functions are activated by the same switches, whenever possible, to provide consistent operation regardless of the SOI or mode selected.

Stick
Weapons delivery related switches on the stick are the trigger, weapons release (WPN REL) button, missile step (MSL STEP) button, expand/field-of-view switch, display management switch (DMS), and the target management switch (TMS). top

Trigger
The trigger is a two-detent switch. Squeezing the trigger to the first detent starts operation of the AVTR (if the AVTR switch is in the AUTO position). Squeezing the trigger to the second detent continues operation of the AVTR and, if gun is selected and armed, fires the gun. top


Weapons Release (WPN REL) Button
The WPN REL button provides consent for weapon release (bombs, rockets, and missiles). This button can also be used for target designation in the DTOS and EO visual modes. top


Missile Step (MSL STEP) Button
The function of the MSL STEP button is mode dependent. In air-to-air modes, depressing MSL STEP button selects the next available missile of the currently selected type. In EO modes, depressing MSL STEP button deselects the current EO missile and selects the priority missile on the next station in aircraft priority. In air-to-ground bombing modes, depressing MSL STEP deselects the current bombing mode and selects the next mode in rotary: CCRP, CCIP, and DTOS. top


Expand/Field-of-View Switch
The expand/FOV switch is used to select expanded or alternate fields of view for the SOI. Repeated depression of the expand/FOV switch steps through the available options in the rotary. The options are as follows:

SOI OPTIONS
FCR (ACM mode) or HUD 30 x 20, 10 x 40
FCR (TWS mode) NORM, EXP
FCR (GM mode) NORM, EXP, DBS1, DBS2
FCR (SEA, BCN, GMT modes) NORM, EXP
WPN (AGM-65D) WIDE FOV, NARROW FOV

top


Display Management Switch
The DMS is a four-position, spring-loaded to center switch used to control SOI selection, format stepping, and the TWS AUTO/MAN rotary.

If CCIP, CCIP rockets, STRF, DTOS, or EO-VIS is selected, the forward position moves SOI to the HUD. When LADD, EO PRE, or CCRP submode is selected along with IR or RP, the SOI designation will move to the HUD when the DMS is moved forward. When TWS is selected, TWS AUTO or MAN submode will be selected.

If the aft position is selected, the SOI moves to the MFD of the highest priority. Subsequent aft depression moves the SOI to the opposite MFD.

The left and right positions sequence MFD format to the next left or right format, respectively, skipping over any BLANK format. The order of format selection is from inside out. top


Target Management Switch
The TMS is a four-position, spring-loaded to center switch which controls target designation and data for the radar, electro-optical weapons, and various navigation/attack modes.

TMS operation is CLASSIFIED. top


Countermeasures Management Switch
CMS information and operation is CLASSIFIED. We can assume that it controls ECM and Flare/Chaff. top

Throttle

The throttle contains four weapons delivery related switches. These are the dogfight/missile override (DOGFIGHT/Missile Override) switch, manual range/uncage/gain (MAN RNG/UNCAGE) control, antenna elevation (ANT ELEV) knob, and cursor enable (CURSOR/ENABLE) switch.


Dogfight/Missile Override (DOGFIGHT/Missile Override) Switch
DOGFIGHT/Missile Override is a three-position switch that overrides any mode except emergency jettison. The DOGFIGHT (outboard) position provides cues and solutions on the HUD for both 20mm gun firing and air-to-air missile delivery. The missile override (unlabeled) position provides only cues for air-to-air missile firing. When DOGFIGHT or missile override is selected, request for master mode changes via the ICP switches will be ignored. Any air-to-air radar mode and any type of air-to-air missile can be programmed for these switch positions. If the switch is in the center position, the last selected master mode is returned. top


Manual Range/Uncage/Gain (MAN RNG/UNCAGE) Control
Use of the MAN RNG/UNCAGE control is mode dependent and serves several purposes. MAN RNG/UNCAGE is actually a combination of two seperate control types. The UNCAGE switch is activated by depressing and releasing the MAN RNG knob.

When in air-to-air gun modes and radar ranging is not available, the MAN RNG knob is used to select one of two manual ranges. Manual range is set to 1500 feet if the knob is rotated clockwise of center and 700 feet if the knob is rotated counter-clockwise of center. The selected value is displayed digitally on the HUD. The target is at the selected range when (1) the correct wingspan has been entered via the DED and (2) the pilot closes until the wings of the target just fill the inside of the manual ranging reticle if using LCOS, or just fit inside the funnel when using EEGS.

The control is also used in air-to-ground, ground map modes to vary the radar gain. Rotating the knob clockwise increases the radar gain. The gain effect of the knob is to add or subtract from the base value set by the gain rocker switch on the MFD. In GMT and DBS modes, moving the knob fully clockwise results in 100 percent gain regardless of the rocker switch setting. In GMT, this knob controls gain of moving target radar returns.

The UNCAGE switch is used to cage/uncage missiles, remove the AGM-65 dome cover, and provide AGM-65 weapon video. top


Antenna Elevation (ANT ELEV) Knob
The ANT ELEV knob is used to manually set the radar antenna elevation angle. Rotating the knob counter-clockwise (backward) from it's mechanically detented center causes the antenna scan center to move upward in elevation to a maximum of +60 degrees. Rotating the knob clockwise causes downward scan center movement to a maximum of -60 degrees.

In the ground map type radar modes, the antenna is positioned in elevation by the FCC using INS elevation data inputs. This value, however, is manually adjustable around the computed value via the ANT ELEV knob as previously described. The ANT ELEV knob may also be used to position the antenna elevation in air-to-air search modes, including SAM. The knob has no effect while the radar is in STT, FTT, GMTT, MTT (with a priority target), ACM, or AGR modes. top


Cursor/Enable (CURSOR/ENABLE) Control
The CURSOR/ENABLE control is a three-axis (X-Y-Z) switch. The CURSOR (X-Y) axis permits slewing of radar cursors. To slew the cursor, the switch is tilted in the desired direction. For EO weapon video, the cursor is fixed in the center of the MFD and the video scene moves.

The ENABLE (Z) axis is used for similar functions depending on the mode. Depressing the CURSOR/ENABLE switch with an AIM-9L/M, AIM-120, or AGM-65 selected changes the BORE/SLAVE option. For AIM-9L/M and AIM-120, the BORE/SLAVE option is changed only as long as the switch is held depressed. For the AGM-65, a permanent change of BORE/SLAVE occurs when depressed. top
