AMP Flashcards
JMPS vs onboard multi helo
onboard dipping only
jmps dipping and buoy
what does AMP do?
estimates TOI position, sensor ranges
recommends sensor placement/settings
populates standard patterns
in jmps only one sensor taken into account, in flight all available are
can jmps make dicass patterns
no
max loadable TOIs
25
only TOI info available in a/c
name
transit spd
weapon spd
TDZ
What does AMP use for SVP?
historical bathymetry database and bottom type database
pulls data for 300 nm sq around operational area for the entire year
when will amp use data from BT buoy or dip?
if within 20nm of center of the area and less than 7 days old
amp search areas
area of interest - toi bound to that area
HVU screen - obvious (can’t be set for multi helo)
Line of bearing - patrol speed based aou
fix - unbounded uses patrol speed for aou
track - sets up an aou that moves with track updates
active sonar range predictions?
based on transmission loss in a 7nmx7nm box
what does amp take into account for range predictions and not take into account?
direct path and short range bottom bounce are taken into account
long range bottom bounce and convergence are not
what is considered Pd<50%
that Pd and average of last 3 Pd all less than 50
Is best evasion depth calculated for all sensors
no just the dome
what is AMP “best search depth”
depth for each sensor that is best against TOI at best evasion depth
what range MDR/TSR indicates AMP is getting bad info
21 yds
Below what frequency slows amp calculations down?
100 Hz
What does AMP take into account when planning an optimized search pattern
a/c position distance to search area toi movement sono inventory amp computed detection ranges or ODR no fly zones land masses aircraft gross weight, wind, OAT
time defaults for optimized search
1 hour for datum
2 hour for dip
2.5 hour for buoy
does AMP account for non homogenous acoustic areas
yes
Is AMP TSR to 50%?
no goes to 25%
of buoys in an optimized pattern
3-8
optimized pattern and water depth
no buoys or dip points when depth is <100’
Will AMP set you to dip within 100’ of the bottom
no
important consideration when inputting a standard pattern
AMP ignores all restrictions
name of the AOU probability model
monte carlo
white and green on coverage map
green = Pd>50
white is 25-50
what can we change about the TOI in aircraft
transit spd
weapon spd
tdz
requirements for AMP to use ANM of beam noise measurement
within 20 nm for ANM
within 1 nm for BNM
min depth of SVP to go to AMP
100’
on SVP display what is yellow, green, blue
yellow historical
green merged
blue collected
min depth for a good SLD
600’
can you just use another a/c BT buoy?
technically need to buoy correct
max number of BT buoy SVPs
4
does the processing mode you are in matter for ANM
no, it will auto command cal omni and auto command back
Considerations for ANM
need valid position
don’t fly close
do it 2x on same buoy, reject first, accept 2nd if within 5 dB
If you stop on way down with dome, do you accept SVP
no
how many dome SVPs can be stored
20
min depth to do a BNM
300’
can you pass multi helo dip patterns in a/c
yes, J28.2 message
How big should an area be to conduct a multi helo optimized pattern
side length 5-10x larger than TSR
