Partition computing of the new Integrated Modular Avionics architecture reduces the heavy cabling of traditional federated architecture. On the other hand, fault-tolerant Operational Flight Programs (OFP) for unmanned aerial vehicles have usually been implemented as primary-backup systems based on dual nodes. However, in the case of a small UAV, it is preferred to implement a S/W fault-tolerant system that runs primary and recovery systems together in a single flight control computer to reduce

In this paper, a new S/W fault-tolerant OFP based on the real-time-object partition, TMO.p, is presented to overcome the large overheads of virtualization approaches.
