Noise Preferential Routes (NPR’s) are in place for departing jet aircraft and were developed as a performance route to direct departing jet aircraft over the least populated areas. All departing jet aircraft are required to follow the NPRs, however, sometimes this may not be possible due to weather conditions or conflicting traffic.
There are two runways at LBA; runway 14 (towards Horsforth) and runway 32 (towards Menston and Burley-in-Wharfedale). The runway used largely depends on the weather conditions, as aircraft take off and land into wind.
There are no established NPRs for arriving aircraft. In addition, turboprops and light aircraft are exempt from the NPR.
