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
