102.1 Define the following acronyms:

  1. RADAR- Radio Detection and Ranging

  2. IFF- Identification Friend or Foe
  3. ADF- Automatic Direction Finder
  4. TACAN- Tactical Air Navigation
  5. IRDS- Infrared Detector System
  6. MAD- Magnetic Anamoly Detector
  7. ESM- Electronic Support Measures
  8. ISAR- Inverse Synthetic Aperture Radar

102.2 Discuss the importance of the Aircraft Static Dissipation System.

Static dischargers are used on the P-3 to allow continuous saticfactory operation of onboard navigation and radio communication systems during adverse conditions by limiting potential static buildup on the aircraft and by controlling interference generated by the corona. Static dischargers are not lightning arrestors. They are attached to numerous points on the aircraft and are fabricated with a wick or wire to provide a high resistance discharge path between the aircraft and the air.

102.3 State the purose of the P-3 Electrical Power Supply system as stated in the NATOPS Flight Manual.

The electrical power supply system provides the necessary AC and DC power for aircraft requirements. Aircraft AC power is furnished by three engine-driven generators (GENs 2,3,4) and one additional generator driven by the APU. AC power is furnished to five seperate AC buses via a series of transfer relays operating in conjunction with the runaround relays and the AC monitoring relays. The six DC buses receive power from three transformer rectifier units. These units receive AC power from main AC buses A and B, and the monitorable essential AC bus, respectively, and provide the necessary output voltage in DC form. Additionally a 24-volt, 31-ampre-hour battery is provided to supply DC power to ground operating bus, start essential DC bus, and APU essential bus via the flight essential DC bus is required. The battery may also supply power to the start essential AC bus via an inverter if necessary.
