An automatic flight stabilization system for a dual-engine drone controls a yaw-correction thrust nozzle, CCC.

  • The drone has a left engine status sensor, LLL, and a right engine status sensor, RRR. An imbalance occurs and a correction signal is needed if only one of these sensors is active (value 1).
  • The correction nozzle must not activate if the manual landing override switch, MMM, is active (value 1).
  • The output to activate the correction nozzle is CCC.

An incomplete logic circuit for this system is shown below:
