Safran Electrical & Power. Fly longer, safer and more efficiently with Honeywell solutions and upgrades for Pilatus aircraft. All rights reserved. The importance and complexity of secondary power in aircraft design is increasing as more sophisticated air vehicles are developed. Although, Power Distribution Units are located inside the aircraft pressurized vessel, ambient temperature can vary in a wide range, while nominal current loads typically depend on specific phase of flight and aircraft configuration. Both peacetime and wartime implications are considered. Power distribution system in an aircraft is very essential in order for the power available at the appropriate generating sources, to be made available at the inputs of the power-consuming equipment and systems, which depends on the type of aircraft and its electrical system, number of consumers and location of consumer components. A primary electric load center (ECL) may be located in a fire-containment equipment bay. A secondary power system for an aircraft utilizes a variable frequency electrical distribution system that provides power to one or more loads that can tolerate distortion components. . These load current and voltage measurement signals can constitute the key characteristics of a majority of electric .
