Why Multi-Stack ?Why Multi-Stack ? PETAL-II Project Needs for MUAC

Operations - Hide AGDL Technology for User Operational Requirements Validation Independent From

AGDL Technology Quick Implementation

Project Has to Compete With Daily Life Activities at an Operational Centre

Take Advantage of Existing Operational Avionics Equipment

Encourage ATN SARPs based Air and Ground Implementations
