ESM

Question 1

Name of ESM system

Answer 1

AN/ALQ-210

Question 2

2 functions of ESM sys

Answer 2

electronic support

SA for EW threats via HTW

Question 3

What is the MDL?

Answer 3

mission data load - effectively a library for the ESM system

Question 4

What is the OFP?

Answer 4

operational flight program - actually runs the entire system based off the information it receives from the MDL

Question 5

Two things that go into HTW?

Answer 5

Time and amplitude (amplitude gives it the “range”)

Question 6

FOV for ESM antennas

Answer 6

100 degrees

Question 7

What is used to determine emitter location?

Answer 7

long baseline interferometry

Question 8

When is classified ESM data corrupted

Answer 8

2 min after loss of power or when commanded

Question 9

What is ESM doing without an MDL?

Answer 9

Searching for 2 mx emitters

Question 10

Max time for sys to load and start working

Answer 10

5-6 min

Question 11

On startup, you get ESM fail, what do you do?

Answer 11

re init, give it 5-6 min then do esm trouble shooting procedure

Question 12

Should you do test>auto on ESM?

Answer 12

probably not, will need to reset ESM and MC power

Question 13

relationship between ESM and RWR?

Answer 13

same receiver so deconfiguring one deconfigures the other

Question 14

can HTW tone be disabled for specific emitters?

Answer 14

yes

Question 15

how many EOI

Answer 15

4

Question 16

What does EOI do?

Answer 16

burns through declutter except HTW

Question 17

Does ESM sector stop processing in that area?

Answer 17

no, just no reports except EOIs and HTW

Question 18

What does SCAN Mod help us do?

Answer 18

Resolve ambiguities by giving us scan rate and scan type

Question 19

Things to consider with scan mod?

Answer 19

Blocks htw and all other ESM
best if emitter is on beam of a/c
check the timestamp on the emitter to ensure it is still going
default time is 10 sec
May interrupt L16

Question 20

4 reasons system will autolocate

Answer 20

MDL directed
operator requested
data fusion
ownship requested

Question 21

Max number of location requests

Answer 21

16

Question 22

threat levels

Answer 22

1 unknown
2 non threat
3 warning
4 imminent threat to surface platform
5 imminent threat to airborne platform

Question 23

max confidence level of esm

Answer 23

95% (most will cap out at 94%)

Question 24

How long does clear track take?

Answer 24

30 sec

Question 25

Clear track and HTW?

Answer 25

Clear track blocks HTW

Question 26

D-ESM and dense emitter environments

Answer 26

may slow the ESM system down

Question 27

max number of operator entries

Answer 27

20
