True or False: Both flight guidance computers must be operational for the autopilot to function.

For autopilot systems in many modern aircraft, it is indeed essential that both flight guidance computers are operational for the autopilot to function effectively. This requirement is primarily due to the need for redundancy and reliability in flight systems. Having two computers allows for cross-checking, ensuring that if one system fails or provides incorrect data, the other can take over and maintain safe operation. This dual-computer setup enhances the overall safety, especially in critical flight phases.

While there may be some aircraft models that could operate with a single flight guidance computer in specific configurations, the standard practice across most types is to require both systems to be fully functional to engage the autopilot. This approach helps prevent scenarios where a failure in a single system might compromise flight safety.
