Whilst the noise lobby does impact how the aerodrome is operated and artificially constrained (80 per hour), operating RWY 25 only is based on the runway selection criteria.
Specifically, ATC must not nominate a particular runway for use if an alternate runway is available when the cross-wind component, including gusts, exceeds 20 KT.
