🔍 Key Concepts

• International air-sea rescue signals used between aircraft and surface craft • Which signals are considered standard distress or response signals versus normal operating actions • The difference between visual maneuvering signals (like rocking wings) and light/throttle signals

💭 Think About

• Which of these options is clearly recognized in air-sea rescue procedures as a "YES, I understand and will comply" signal from an aircraft? • Is any option likely to be confused with ordinary operation of the aircraft, rather than a deliberate reply signal? • Which signal involving lights might interfere with or be confused with normal navigation or anti-collision lighting requirements for aircraft?

✅ Before You Answer

• Verify which actions are listed as standard aircraft reply signals to surface craft in air-sea rescue tables (wings, throttle, lights, Morse). • Check whether flashing navigational lights is ever prescribed as a communication signal between aircraft and surface vessels. • Confirm which options could be accidentally produced during routine flying and therefore are not recommended as deliberate communication signals.
