This "Pilot Pass" system allows you to receive various rewards by clearing certain conditions and earning points in large scale battles. Activity points (AP) can be obtained by clearing the conditions described in "STANDARD ACTIVITY" and "EX ACTIVITY" in a large-scale battle. When the AP accumulates to a certain value, the "Pilot Pass LV" rises. And when the Pilot Pass LV rises, you get the "Pilot Pass Reward" according to the level.
You can also get AP by clearing the "NET CAFE ACTIVITY" by logging in from a net cafe, if you are living in Japan right now.

More details regarding this Pilot Pass system:
Standard activities include "Daily" and "Weekly". "Daily" activities are updated daily at 12:00 PM JST. Weekly activites are updated when the maintenance hits.
The Pilot pass level and rewards will be reset every "section", which goes for around 28 days. Might change according to future situations.
You can purchase the "GO License" for 3000 BC to obtain the "High Grade" rewards from the Pilot Pass (the bottom two rows) alongside other benefits.
For old players - with the implementation of Pilot Pass system, the old "Weekly Win" (Master Mechanic ticket bonuses according to how much you've won in that week), daily challenges, and perfect challenges will be erased. Clan Challenges stays but it will disappear from the challenge tab, and can only be accessed from the Clan tab.
