Sights & Sensors Flashcards
Explain what the following RMS modes do:
- ATRK
- MTRK
- MANT
- DMGT
- GNDT
- INT
- PHMS
- GHMS
- FF
ATRK = Auto tracking (1 box)
MTRK = Multi Tracking (2+ boxes
MANT= Manual Tracking (you drive the sight around)
DMGT = RMS slaved to the current DMGT point
GNDT = RMS is holding a ground position based on range
INT = Integrator, holds a consistent slew rate (Only works from MANT mode)
PHMS = Sight is slaved to Pilot helmet mounted sight
GHMS = As above but gunner
FF = Fix Forward
What is the acronym for recognising armoured vehicles and what does it mean?
H - Hull (Tall vs short vs wide)
A - Armament (Shape/size/location)
T - Turret (Suppressor/length)
S - Suspension (Wheels size, tracks)
What is the acronym for recognising aircraft and what does it mean?
W - Wings
E - Engines
F - Fuselage
T - Tail
How can you tell the difference between an ASLAV and a BTR?
BTR has a angle at the back (more angle = older)
ASLAV has more of a gap between the wheels
BTR has a smaller turret and its further forwards
What limits are applied to the RMS HARMO and what restrictions are applied if HARMO fails?
HARMO Valid:
- Within 2.5hrs
- +/-10ºC
When failed:
- TV only for targeting/LFRD use
- HMSD
What is the Acronym for IR environmental/target visibility factors?
R - Reflectance (Good)
A - Absorbance (Bad)
T - Transmittance
E - Emissivity
T - Thermal Crossover
What is the acronym for the LASER environmental/targeting factors?
B - Bore sight (Was it done)
A - Attenuation (Loss of power with distance)
D - Divergence (2m wide @8-10kms)
J - Jitter (Vibration)
O - Overspill
B - Backscatter (Laser reflected by atmospherics)
U - Underspill
P - Podium (Only once side of the building can be seen)
E - Entrapment (
Explain MRT and thermal crossover?
MRT = Minimum resolvable temperature (temperature sensitivity of the IR camera)
Thermal Crossover = When ground/vegetation temp is the same as that of metal/plastic (IR all looks the same)
Explain how gain and focus are used in the aircraft?
Gain - Only relevant for IR therefore left/right
Focus - Only relevant for TV therefore up/down, not typically used since auto focus is good
Explain under/over spill?
Under/over spill is when laser energy is hitting something short/long of the target respectively
Explain what happens when the FSP selects gunner vs STD for their ranging?
When in GUNNER, it gives the FS pilot the manually entered ranging and weapons release profiles for the ACP-G, instead of the standard setup, rarely used because the standard setup is pretty good
What does the gun up button do?
Gun forward and deactivated
What laser restrictions are placed by the wire cutter?
10º limit from wire cutter can’t fire the laser
What are the standard DVR-CP switch selections on startup?
IR - MFD3 - OFF (Rec selected prior to engagement)
What are the different ranging techniques?
Kinematic ranging —> In GNDT, manually ranging so that the sight remains on the TGT
Stadiametric ranging —> Gun circle = 15m, if 8m vehicle then it takes up half then range is correct
LOS Estimation —> LRFD calculates range
Map Estimation —> Using the map to guess range based on the TGT ring next to a geographic feature
Explain what the following are:
RWR
LWR
MLD
RWR —> Radar Warning receivers (4x, black circles)
LWR —> Laser Warning Recievers (2x, glass on wingtips)
MLD —> Missile launch detectors (4x, glass, all data through MDL1 front left)
Explain what the following symbols would mean with regard to the EWS:
Circle
Triangle
Diamond
Square
Circle —> Rotating radar
Triangle —> Tracking radar
Diamond —> Continuous wave radar
Square —> Track while scan
Explain how the CMDS works when in Semi vs Auto and what fast trigger does:
Semi —> Manual release via EWS ACK button, aircraft releases the most effective counter measures for the threat
Auto —> Auto release, auto best pattern
Fast trigger —> When targeted aircraft releases an initial small response
Regarding the EWS, what do the following acronyms mean when being targetted:
UCW
TT
TA
MG
AI
UCW —> Unknown
TT —> Target track (System is looking but not tracking you)
TA —> Target Acquisition (You are being actively tracked)
MG —> Missile guidance (there is a missile coming for you)
AI —> Airborne Interceptor (fast jets)
What does the survive button do and when is it used?
Releases a pre programmed mixture of chaff and flare, used when the EWS hasn’t seen a missile but you have
How does flying in rain/poor visibility impact the RMS?
Rain makes everything the same temperature, therefore IR is degraded but TV remains
Poor vis (due smoke/cloud) reduces TV fidelity but IR remains
Setting up from the rear seat, what is the setup process for the SIM?
MFD:
(5+SIT) TAC Maps (x2): SSC+GRS+LOS+DCP or CP+Zoom A/R —> SIT Page
(3+ EWS-CP)EWS (x2): REC, AUD ON, CMDS visible + EWS CP: ON + Semi
CDU: (bottom to top)
(5) STP: DID-P + EWS to SYS, Laser codes, GRS, Gun rounds
(2) TAC: GS Slave, DL Assign
(5) EWS: Norm, fast trigger off, audio test, PERM
(5)MM: C/S, J/Bingo, XPDR code, IFF mode
(3) COM: Confirm EWS vol, HF, SEC (OPS/ARH2)
(3) NAV: Ref point, DT, Route (EELs),
How do you know how many WPs are being used in the system?
Shows total WP in the bottom of the SIT page
Explain the verbage and button presses for a “Gunner target”:
FS: “Gunner TGT, vehicles/smoke/homestead etc”
RS: GAG-R —> Double tap
RS: GAG-L —> Zoom out —> white/black hot
RS: “Captured, I see _____ orientated ____”
From here, get range, switch to TV and identify the TGT
What is said for the FENCE Cx?
F - M/ARM ON, CFS-Safe guards open, Gun __ rounds, Rocket ___ total, HF ___ Alpha codes
E - LRFD codes set A & B, keys on switch on, ELC confirm Calcutta, ILC set
N - Route EELS, Ref point ____, G/S slave on ___, TAC page have overlays loaded, DH set ___, Bingo ___, Joker ___
C - Tactical volumes up, audio test complete, squawking 46__ in mode ___, data link freq ___
E - NORM, FT OFF, PERM, Semi, powers on, EWS page recording __, __ flares with __ chaff
Explain what the terms “Stable” and “Contraints” mean:
Stable —> Means the the front seat is on target, allowing the RS to activate
Constraints —> FS responds with “matched”, means that a valid firing solution and all limits are being met
How can you determine the size of the laser spot?
20cm every 1km, therefore 5Km = 1m, 10km = 2m
Explain the verbage as part of the race track pattern from the “Turning in” point:
FS - “Turning in/tipping in”
BC - “Sensors in TGT area” … “Tally TGT”
BC - “Lasing” …
FS - “Stable”
BC - “Armed, activated, ____m, HDG, nil messages …. Constraints?”
FS - “Matched”
BC - “Firing” …. “Matched” (FS) —> Firing (Rifle A/R)
BC - “Switching to gun” —> “Lasing, ____m” —> Constraints?
FS - “Matched”
— Pre Break —
BC - “Deactivated, Safe, FF, DVR Off”
FS - Breaking right/left
Explain the process for a HMSD boresight:
FS: “Gunner TGT” —> Double tap “Captured” —> compares RMS with reticle, adjusts A/R
BC: 1-2-1, compares RMS with reticle, adjusts A/R
