Duty to Render Assistance Over Water
A private pilot flying a single-engine aircraft over a coastal area at 3,500 ft hears a distress call on the common frequency from a yacht taking on water. The pilot's aircraft carries a life raft, but the pilot has no training in sea rescue and the aircraft has no winch or hoist. The pilot's fuel state allows about 40 minutes of loiter. A coastguard helicopter is 25 minutes away. The pilot's passenger is anxious and asks the pilot to descend to 500 ft to circle the yacht. There is a strong onshore wind and the sea is rough. The pilot's licence is valid and the aircraft is insured for private operations.
1. Does the pilot have a legal obligation to assist, and what does that obligation require in practice?
Read the worked answer
Under international conventions and most national laws, the pilot in command of an aircraft has a duty to render assistance to persons in distress at sea, insofar as it can be done without serious danger to the aircraft or persons on board. The duty is not absolute; it is qualified by safety.
In practice, the pilot should acknowledge the distress, relay the position to the coastguard or rescue coordination centre, and remain available as a communications relay or surface marker if it is safe. The pilot is not required to attempt a sea landing or a rescue for which the aircraft and crew are unequipped.
Descending to 500 ft in rough conditions with an anxious passenger and no rescue training may create more risk than it removes. A better contribution is to maintain altitude, establish communications, and pass accurate position and drift information to the helicopter.
2. How should the pilot weigh the request to descend, and what should the pilot actually do?
Read the worked answer
The pilot should assess: fuel (40 minutes loiter), sea state, wind, aircraft capability, passenger welfare, and the arriving helicopter's timeline. The helicopter is 25 minutes away, so the pilot's most useful role is to remain overhead at a safe altitude and act as a radio relay and position marker until the helicopter arrives.
Descending to 500 ft in an onshore wind and rough sea reduces margin for error and may distract the pilot from communications. The passenger's anxiety is a real factor; the pilot should explain the plan calmly.
The pilot should: acknowledge the distress, record the yacht's position and drift, inform the coastguard, maintain a safe altitude, keep the yacht in sight if possible, and depart for fuel before reserves are compromised. The pilot should not attempt to land or drop equipment. After landing, the pilot should be prepared to provide a statement to the rescue authority.
