Answer
  • Pressure purged from the engine.
  • Ignition of pyrotechnical cartridges.
  • Electrically powered from engines.
  • Small pneumatic ejectors.

Answer
  • IR passive sensor.
  • UV passive sensor
  • Laser/GPS guidance.
  • Radar guided (active, semi-active, passive).

Answer
  • Missile approach warning (IR/UV).
  • Radar warning
  • Radar Doppler Missile Warning.
  • Laser warning .

Answer
  • Angular gate stealing.
  • False Velocity Generation.
  • False target generation.
  • Range gate stealing.
  • Velocity gate stealing.
  • Angle track breaking.

Question 6

Question
Which aspect of weapon integration shall prevent mechanical interference between a store and any element of the aircraft or the environment?
Answer
  • Geometric Integration
  • Functional Integration.
  • Environmental Integration.

Question 7

Question
Which sentence better suits the definition of jettison?
Answer
  • Uncommanded release of armed weapons.
  • Uncommanded release of non-armed weapons.
  • Commanded release of unarmed weapons.

Question 8

Question
What is a DIRCM?
Answer
  • Metal-coated dielectric fibers that when dispensed in large numbers can produce strong radar echoes.
  • A flare that burns with an IR wavelength similar to the target aircraft IR signature.
  • A Direct Infrared Countermeasures System Demonstrator.
  • Infrared counter measure system that tracks and directs energy towards the threat.
  • A decoy attached to a thin cable, which can gradually be reeled out behind the aircraft, to confuse an enemy and draw his radar, or the seeker of an approaching radar guided missile
  • Technology developed to protect aircraft against attack from sophisticated Infrared guided missiles
  • DIRCM systems consist of a missile approach warning system that detects the launch and approach of the missile, and a director system, e.g. a turret, that is cued to track the approaching missile
  • System produced by Northrop Grumman and BAE Systems to protect aircraft from infrared homing manportable missiles.

Question 9

Question
Which is the correct definition for Electronic Support Measures (ESM)?
Answer
  • Division of EW involving actions taken to prevent or reduce an enemy’s effective use of the EM spectrum, through the use of EM energy.
  • Division of EW involving actions taken to ensure friendly effective use of the EM spectrum despite the enemy’s use of EM energy.
  • Division of EW involving actions taken to search for, intercept and identify Electromagnetic (EM) emissions & locate their sources for the purpose of immediate threat recognition.

Question 10

Question
What signals enable and inhibit the Release Consent?
Answer
  • Only enable and inhibit missile firing/bomb release.
  • Only enable or inhibit the fuze settings on flight.
  • Only enable and inhibit safety critical store functions which are commanded by the aircraft over the data bus interface.

Question 11

Question
In accordance with MIL-STD-1760 where store RT address has to be coded
Answer
  • The store RT address is coded at MSI and ASI levels
  • The store RT address is coded at ASI levels.
  • Each store comes with its own RT address code from supplier.

Question 12

Question
Which of the following characteristic is true for UV Missile Approach Warning?
Answer
  • It is an active sensor.
  • Several sensors provide full coverage.
  • It is a passive system
  • There are not natural background sources that can obscure the emissions.
  • Lower false alarm rate.
  • Low detection distance due to attenuation.
  • Each sensor coverage may be as much as 110º.
  • Several sensor provide full hemisphere horizontal coverage.

Question 13

Question
Which of the following characteristic is true for IR Missile Approach Warning?
Answer
  • It is an passive sensor.
  • Only one sensor provide full coverage.
  • IR emission can be obscured by the background emission.
  • Discrimination require to avoid false alarms
  • Better and farther identification of the source.
  • Each sensor coverage may be as much as 110º.
  • Several sensor provide full hemisphere horizontal coverage.

Question 14

Question
Which are possible Radar air to air missiles guidance methods?
Answer
  • Semi active guidance (passive detector of a radar signal provided by an external source).
  • Four points guidance (missile detector is homing on four points in the target shape).
  • Active guidance.
  • Passive guidance.
  • Pursuit
  • Lead angle
  • Three point
  • Proportional

Question 15

Question
