Airtime hills explained

An airtime hill is a crest shaped so the train's path briefly produces negative G or “float.” You lift against the restraint instead of being pressed into the seat.

Designers tune radius and entry speed: a shallow hill at high speed gives sustained float; a sharper hill can feel like a snap.

Floater airtime is gentle negative G; ejector airtime is sharper and shorter. Both show up on the same ride in different spots — ranking coasters by airtime is subjective for good reason.
