What 3 things need to happen before a high voltage check?
Engines on
Flaps between 1 - 25
Parking brake off
What is the frequency of the radar?
9.35 - 10.15

50kW
What is the power of the REP pulse?
1W
What is the max number of TWS tracks?
512 in FR85
What does ATI stand for?
Automatic Track Initiation
What was R designed for?
Open blue water
Low manoeuvring targets
Why does the speed of a TWS contact seem fast at first?
The prediction algorithm updates in a very short period of time, so thinks the contact is moving quickly.
Which mode does R gain new contacts?
Search
What is the roll limitation of R?
18.75
What is the cut off distance from land for new contacts in R?
2.5nm
How many contacts can R handle?
2000
What system handles TWS?
TOMS
What system handles R?
RDC
What criteria must be met for R to create a contact?
5 detections in 7 opportunities
After how many detections is C/S generated in R?
150
In R what symbol appears when a contact is good for ISAR?
a green circle
What are the 5 promo levels of R?
promo 0 - tentative (internal)
promo 1 - provisional (internal)
promo 2 - established (<150, blue circle)
promo 3 - coasting (DR)
promo 4 - persistent (>150)
What is the default coast time for R
180s
What are the height limits for SAR?
4000 - 41000ft
What is the best grazing angle for SAR?
4-9 (7.5)
1nm = 1000ft
Then for every 10,000ft take 1000ft off
e.g. 10nm is 9000ft
What is the GS limit for SAR?

0.5 - 2
2 - 18
18 - 40
Which band doesn’t provide geolocation?
HB
How does geolocation happen?
Interferometry and amplitude comparison

Top Right: Acoustics Rx
Bottom Right: Acoustics processor
What components does the IBU work with?
DME
IFFI
V/UHF1
Radar
TACAN
IFFT
L16
TCAS
What components does the FACS consist of?
2 cold plates
Reservoir, Pump and Controller module (RPC)
Heat sink
Fluid lines
What powers and controls the FACS?
SPDS
What are the “problem” signals from the FACS?
Degraded - low coolant level or single pump failure
Malfunction - no flow, and after 10s SPDS removes power from the RPC
