FCR page

Open it with the FCR button. Only an aircraft with the radar fitted has one; any other shows FCR NOT INSTALLED. How to scan, choose a mode and engage with the radar is on the Fire control radar page.

The page follows the radar’s mode, which is set with the mode keys, not on the page:

Mode	Shows
GTM, ground targeting	Ground targets ahead, in a wedge.
ATM, air targeting	Moving aircraft and helicopters all round, on a circle.
RMAP, radar map	The GTM wedge with a picture of the terrain the radar sees behind the targets.
TPM, terrain profile	The terrain ahead and whether it clears you. No targets.

1. 1Heading tape With the FCR centerline below the lubber line, and the next waypoint’s bearing (the caret).
2. 2Target count How many targets the radar has found.
3. 3Scan sector Range arcs every 2 km out to 8 km. The sector width follows the scan size.
4. 4Scan bar Sweeps across the sector while the radar scans.
5. 5NTS The next-to-shoot target, in the diamond. The triangle marks the alternate, the ANTS.
6. 6Targets One symbol per target: what it is and whether it is moving. See the table below.
7. 7Sight and range Your sight, and the range and its source.
8. 8Sensor window Where the TADS looks (the box) and where your acquisition source points (the diamond).
9. 9Weapon The weapon actioned.

The scope

Your aircraft is at the bottom of the GTM wedge, or the centre of the ATM circle. The arcs are every 2 km, out to 8 km. The sector being scanned is drawn bright, set by the scan size; the rest of the wide sector stays dim. In ATM the wide sector covers everything except about 12° either side of the tail.

The display is drawn about the radar’s centerline, not the nose: slew the centerline 30° right and the middle of the wedge looks 30° right of the nose.

While the radar scans, the scan bar sweeps across the sector: green for a continuous scan, white for a single scan.

Around the scope

Item	Shows
Heading tape	Your heading. Below it: the FCR centerline (the solid mark), where the last scan looked, the next waypoint’s bearing (the caret), and the other crew station’s sensor.
Target count, top right	How many targets the radar has.
Sight and range, bottom left	Your sight (such as C-FCR, P-HMD, TADS, or TADSL while linked) and the range with its source. See Sights and acquisition.
Sensor window, bottom centre	Where the TADS is looking, as a box, and where your acquisition source points, as a diamond.
Weapon, bottom right	The weapon actioned: for the pilot’s, its state (rounds, rocket type and count, or the missile trajectory and mode); for the CPG’s, CGUN, CRKT or CMSL. COOP in a cooperative rocket engagement.
Elevation scale, far left	The antenna elevation. It does not move: ELEV is always AUTO.

Buttons

Button	Label	Action
T1	C SCP	Shows the radar’s targets on your helmet display, at their places in the outside world, or in the TADS picture when it is up. Boxed when on. Only on your own display.
L1	NTS	Steps the next-to-shoot to the next target. The same as Arma’s Lock target key.
L2 / R2	arrows	Slews the scan centerline left or right. See Fire control radar.
L4	TGT	Stores the NTS as the next free target point, T01 to T50. Barriered while there is no NTS.
R6	ACQ	Opens the acquisition source list.
B1		MENU.

NTS, TGT, RF HO and the arrows are shown only while the FCR is your sight. NTS and the arrows work only for the crew station that owns the radar.

UTIL, ZOOM, RF HO and ELEV are not simulated.

Target symbols

Each symbol shows what the target is and how it sits. Symbols are yellow; a dim one is a weaker return, sorted to the end of the list.

The 1.5 km split is only how the symbol is drawn. It does not decide how a missile is launched.

Symbol	Meaning
	NTS, the next-to-shoot: the target a radar-guided Hellfire will be given.
	The NTS while no weapon is actioned.
	ANTS, the alternate: the target NTS steps to next.
	Shot at: where a missile has been fired.
	An obstacle, in TPM.

The radar also picks up some clutter: false returns from the ground, two or three at a time, that look like unknown or vehicle symbols and come and go from one scan to the next.

RMAP

The radar map is the GTM page with a picture behind the targets: the strength of the radar return from the terrain, brighter for stronger, black where the terrain is hidden from the radar. The near half, to 4 km, is painted as the bar sweeps one way, the far half, 4 to 8 km, as it sweeps back. The picture stays up after a scan until the next one starts.

Select RMAP again to turn the picture off and on. The buttons are the same as GTM’s.

TPM

The terrain profile mode is for flying low at night and in bad weather. It scans ahead 2.5 km, across 180° below 45 knots and 90° above 55 knots, and shades the terrain against a clearance plane set below your wheels:

Shade	Terrain
Black	Below the clearance plane: clear.
Dark grey	Above the clearance plane but below you.
White	At or above your height.
Grey	Hidden from the radar, or not measured.

Up to four profile lines join the highest terrain the radar sees at set distances. Obstacles, such as towers and masts at least 8 m high or anything 13 m high, are marked, and their number shows top right.

Button	Label	Action
T1	C SCP	Shows the profile lines and obstacles on your helmet display.
L1	PROF	Where the profile lines are taken. GEOM: 100–300, 300–500, 500–1,000 and 1,000–2,500 m. ARITH: four equal bands from 100 to 2,500 m. TEST: 500, 1,000, 1,500 and 2,000 m.
L2	LINES	How many profile lines are drawn, 0 to 4.
R1	CLEARANCE	The clearance plane: 20, 50, 100 or 200 ft below you.
R2	ELEV	The antenna’s look: FAR, nearly level, for terrain out to 2.5 km, or NEAR, tilted down, for close terrain.
B1		MENU.

PROF, CLEARANCE and ELEV can only be changed by the crew station that owns the radar.
