There are many reasons why a plane might need to divert to another airport, from engine failure to medical emergencies. The diversion airport is selected by the captain, who will choose an airport that can accommodate the aircraft in its current condition. Once a diversion begins, ATC will issue a new clearance for the flight to follow.

What You'll Learn
The captain selects the diversion airport
The captain will work with the airline's operation centre to determine the best diversion airport. Operational suitability, the patient's condition, and medical needs are all considered. If the flight is nearby a major medical centre or outstanding medical care, priority can be given to that airport. If the situation is dire, the captain can divert to the nearest suitable airport with available medical facilities. If the patient's condition is stabilised, the captain may also elect to divert to an airport that will speed the process of getting the flight back in the air.
Aircraft can only safely divert to suitable airports, that is, airports that can accommodate the aircraft in its current condition. With a technical issue like single-engine operation, stuck flaps, or a landing gear malfunction, airports that would normally be suitable may now be off-limits. Similarly, weather conditions at nearby airports may be out of bounds if the aircraft is suffering from a technical issue. For long-haul flights, a technical diversion can often mean returning to the origin airport, even if it means bypassing numerous airports that could handle the aircraft.

The flight crew works with the airline's operation centre to determine the best diversion airport
When a flight needs to divert to another airport, the flight crew works with the airline's operation centre to determine the best diversion airport. The captain will select the airport if there is an urgent reason to divert, such as engine failure, smoke/suspected fire, or a medical emergency. In these cases, the captain will choose the airport so that the plane can land as soon as possible. However, if the situation is not as dire, the flight crew and dispatchers will work together to find the best alternate airport.
There are many factors that are considered when determining the best diversion airport. Firstly, the aircraft can only safely divert to suitable airports, meaning airports that can accommodate the aircraft in its current condition. For example, if there is a technical issue with the aircraft, such as single-engine operation or a landing gear malfunction, certain airports may not be suitable. Similarly, weather conditions at nearby airports may make them off-limits if the aircraft is suffering from technical issues.
Another factor that may be considered is the proximity to medical care. If a patient on board requires medical attention, priority may be given to an airport that is near a major medical centre or outstanding medical care. If the patient's condition is stabilised, the crew may also elect to divert to an airport that will speed up the process of getting the flight back in the air.
Once a diversion begins, ATC will issue a new clearance for the flight to follow. The flight crew will be in discussions with the dispatcher, either via iMessage or text messages over ACARS. They will ask ATC for the nearest airport and declare an emergency, and the controller will clear them directly or give a vector.

The aircraft can only divert to suitable airports
If an aircraft needs to divert to another airport, the captain will select the diversion airport. If the diversion is due to an urgent issue, such as engine failure, smoke, fire, or a medical emergency, the captain will select the airport that will allow them to land as soon as possible. However, the aircraft can only divert to suitable airports. A suitable airport is one that can accommodate the aircraft in its current condition. For example, if the aircraft is experiencing a technical issue, such as single-engine operation, stuck flaps, or a landing gear malfunction, an airport that would usually be suitable may not be an option. Similarly, if the aircraft is experiencing technical issues, weather conditions at nearby airports may rule them out as diversion options.
ATC will issue a new clearance for the flight to follow once a diversion begins. If the aircraft is diverting due to a medical emergency, the flight crew and airline's operation centre will work together to determine the best diversion airport, taking into account the patient's condition and medical needs. If the situation is critical, the crew may divert to the nearest suitable airport with available medical facilities. If the patient's condition is stable, the crew may divert to an airport that will speed up the process of getting the flight back in the air.
