Home / Jonah’s Page Jonah’s Page Key Highlights – Training Module Climbing turns are quieter than level and/or descending turns. Accelerating climbs are quieter than steady-state and/or decelerating climbs. Collective climb is quieter than cyclic climb. Steeper take-offs greatly reduce the noise footprint. A steep approach glidepath reduces the size of the noise footprint. Make smooth control inputs to reduce the noise footprint.
