Probabilistic Trajectories of light General Aviation operations ALIAS 2014 – European University Institute - FiesoleDamiano Taurino

in behalf of the ProGA Consortium

ProGA Project

study the feasibility of a system that can continually and automatically predict the future GA aircraft’s flight corridor or its volume of operation

WAY FORWARD

Develop a prototype HMI

Validate the concept with pilots by means of simulations, interviews, observations

Assess the foreseen benefits of a ProGA system in the key performance area of safety

Determine the social acceptance within the GA community of sharing location and intent during flight

Understand certification issues: is it part of the cockpit or just a support tool (e.g. Electronic Flight Bag)?

“A portable EFB is a portable EFB host platform, used on the flight deck, which is not part of the certified aircraft configuration. It hosts type A and/or type B as well as miscellaneous (non- EFB) software applications. If mounted, the portable EFB must be easily removable from its mounting device without the use of tools, by the flight crew.” (CAA UK definition)

LIABILITY AND INSURANCE

It is not an autonomous/automatic system, but it still supports the Pilot in Command in decision making (by presenting a probabilistic information)

In the case of an accident may the use of the tool somehow affect pilot’s liability (negatively or positively)?

Liability and non-certified equipment (e.g. in the case of non-reliable position data transmission)

May the use of the tool bring benefits when taking out insurance (due to enhanced safety)?
