Final answer:
Air refueling is a technique used in aviation to transfer fuel from one aircraft to another in flight. Procedures for air refueling include radio silent procedures and visual signals.
Step-by-step explanation:
Aviation
Air refueling is a technique used in aviation to transfer fuel from one aircraft (the tanker) to another (the receiver) while in flight. The process involves connecting a fuel hose or probe from the tanker to the receiver, allowing fuel to flow through. To ensure safe and efficient refueling, pilots use specific procedures, including radio silence and visual signals such as flashing pilot director lights and the lower rotating beacon on the tanker.
