Economical Memory Management for Avionics Systems

Unlike old-fashioned aircrafts that almost did not have avionics systems, up to date aircrafts have numerous avionics systems. Nearly all new aircrafts have devices for navigation, automatic flight control, collision avoidance systems, flight data recorder, weather radar system in addition to communication and monitoring systems. All of these devices employ embedded computer systems with growing memory requirements. To facilitate reduction of the electricity power required for these devices, detecting the portions of the computer memory that are currently not in use is suggested. The unused portions can be temporarily shut down and after that turn them on when they are required again. Such a power cut can greatly lower the electricity consumption of the aircraft's avionics devices.
