MIL-STD-704 Training | Aircraft Electrical Power Characteristics, MIL-STD-704F Version

MIL-STD-704 Training, Aircraft Electrical Power Characteristics, covers details of standardized power interface between a military aircraft and its equipment and carriage stores covering interfaces such as: voltage, frequency, phase, power factor, ripple, maximum current, electrical noise and abnormal conditions (overvoltage and undervoltage), for both AC and DC systems.

Learn about  MIL-STD-704 requirements, testing and measurements to ensure compatibility between the aircraft electric system, external power, and airborne utilization equipment.

MIl-STD-704 training course covers requirements and characteristics of AC and DC power for aircraft provided at the input terminals of electric utilization equipment including test methods and procedures for determining airborne utilization equipment compliance with the electric power characteristics requirements defined herein. Electromagnetic interference and voltage spikes are not covered by this standard.

To ensure that aircraft electronics and other electrically-powered equipment will operate reliably, tests under extreme power conditions are required: Guidance for Test Procedures for Demonstration of Utilization Equipment Compliance to Aircraft Electrical Power Characteristics are covered including:

  • Demonstration of Utilization Equipment Compliance to Aircraft Electrical Power Characteristics
  • Single Phase, 400 Hz, 115 Volt
  • Three Phase, 400 Hz, 115 Volt
  • Single Phase, Variable Frequency, 115 Volt
  • Three Phase, Variable Frequency, 115 Volt
  • Single Phase, 60 Hz, 115 Volt
  • 270 VDC
  • 28 VDC

Power testing is required to demonstrate compatibility of avionics with aircraft electrical power under operating conditions and power groups of MIL-STD-704.

Who Should Attend

Electronic  engineers, system engineers, testing engineers, verification and validation engineers, QA engineers, technicians, avionics systems engineers, hardware and software design engineers, aircraft personnel, managers and employees with little or no MIL-STD-704 knowledge or experience.
