In the frame of Ariane 5 performance improvement plan, several ideas have arisen. One of them affects the Cryogenic Upper Stage (ESC-A). Indeed since the Ariane 5 flight V 157, the loading level of liquid hydrogen has been raised in order to improve the performance of the launcher, enabling to increase the payload mass or the altitude of the delivery orbit. However, this change raises safety problems. Optimal safety should be guaranteed both on ground and during flight. However, this study focuses only on the flight preparation phase, that is to say the ground phase starting from tank loading until lift-off (H0).
