Final answer:
If a passenger requests a deviation in flight and enroute, the procedure involves communicating the request to the flight crew or cabin crew, who assess the feasibility
Step-by-step explanation:
The correct answer is option 3. If a passenger requests a deviation in flight and enroute, the procedure would involve communicating the request to the flight crew or cabin crew, who would then assess the feasibility of the deviation based on factors such as airspace restrictions, fuel consumption, and safety considerations.
For example, if a passenger requests a different destination than the original flight plan, the crew would need to coordinate with air traffic control and possibly request a new flight plan. If the deviation is approved, the crew would relay the updated information to the pilots, who would make the necessary adjustments to the route.
It's important to note that deviations in flight and enroute may be subject to airline policies, regulatory requirements, and the availability of alternative routes.
