Flight Watch refers to the ongoing process where an aircraft operator, or a contracted service provider acting on their behalf, maintains continuous two-way communication with an aircraft in flight. This approach aims to boost the operational efficiency of flights. Essentially, Flight Watch builds upon operations control, making it more proactive. By actively monitoring factors that could impact a flight’s journey, ground personnel can engage in real-time tactical planning.
This system allows the Aircraft Commander to update the operator about any changes in flight plans, such as deciding to land at an alternative destination due to technical issues. This way, the operator can make necessary arrangements and secure clearances in advance. Having reliable direct communication with each aircraft enables quick relaying of route change suggestions to the aircraft commander. These changes may result from unexpected weather conditions or air traffic control delays that could be avoided by re-routing.
In many cases, a well-equipped ground team can track these developments more efficiently than the flight crew can from the aircraft. Effective Flight Watch relies heavily on two-way voice communications with the aircraft crew. For most operations, particularly beyond short-haul flights, this typically involves satellite communications or HF radio. In remote areas, where HF coverage can be unreliable, the effectiveness of air traffic control communications may diminish.
Real-time updates from the crew are crucial for ensuring that the advice provided by the Flight Watch team remains relevant. If continuous voice communication is not possible, the Aircraft Communications, Addressing and Reporting System (ACARS) can offer limited interim communications, mainly for simple instructions or automated messages related to the aircraft’s status.
Following the loss of Air France Flight 447 in 2009, there has been interest in enabling higher volumes of aircraft data for accident investigations, which could help enhance Flight Watch capabilities. If successful, this could allow the collection of real-time fuel burn and endurance data. Typically, comprehensive Flight Watch services are found among larger fleet operators who have enough flight activity to justify a dedicated team of specialists. These operators are not limited to airlines; they can also include large business jet operators, especially those with fractional ownership.
For smaller operators, it may be feasible to share Flight Watch services by hiring a subcontractor with a specific focus. While some Flight Watch personnel specialize in aviation meteorology, most come from a generalist background, often having experience in operations control, overseeing aircraft turnarounds and departures.
