Abstract

The present invention relates to a system and a process for providing improved operational safety for aircraft. The system/process of the instant invention utilizes real-time, two-way transmission of voice and/or text and flight-critical data between an aircraft and a ground-based computer workstation, where transmitted information monitored and acted upon as necessary by a qualified flight safety person, e.g., a appropriately trained individual (including but not limited to a safety pilot or other person trained in safety procedures). This safety person can perform a number of functions that would enhance flight safety, such as reducing the workload of the primary pilot(s), assisting in the performance of routine checklists, monitoring communications with air traffic control, and advising the pilot in the aircraft on how to handle any in-flight situations that may arise. By providing many if not all of the advantages of a second or third pilot in the aircraft cockpit without imposing additional weight or space requirements on the aircraft, the system/process of the instant invention can increase flight safety while reducing the associated costs.
