Definition
An operation in which one pilot flies the aircraft alone, without a second crew member, and is therefore responsible for all flying, navigation, communication, system management, and decision-making tasks. In the context of helicopter Rotorcraft Flight Manual limitations, certain helicopters are certificated or restricted for single-pilot operation only from a designated seat (commonly the right seat), and the manual specifies which seat must be occupied and any associated weight, equipment, or procedural conditions.
Plain English
Flying the aircraft on your own, with no other pilot on board to share the workload. The flight manual will tell you which seat you must sit in and any rules that go with flying it solo.
Context Anchor
Seen in helicopter flight manual limitations, especially where the manual states whether the helicopter may be flown by one pilot or requires a second pilot for certain kinds of flight.
Why Pilots Care
Determines whether a given procedure, autopilot mode, or aircraft configuration is approved when no second pilot is available, directly affecting legality and safety margins.
Intuition Check
Do not assume single-pilot operation only means “one person is in the aircraft.” It means one qualified pilot is the only required pilot for that flight under the aircraft’s approved limits and the rules.
Example Sentence 1
The Rotorcraft Flight Manual states that single-pilot operation must be conducted from the right seat with the left-seat cyclic removed.
Example Sentence 2
Single-pilot operation requires the autopilot to remain engaged during en route segments as stated in the limitations section.
