Fly Quiet League

As the Heathrow Fly Quiet League begins its second year, figures for October to December 2014 provide an initial set of data that can be compared to the same three-month period from 12 months before and which take into account airlines’ efforts in improving their League performance. 

From now on, Fly Quiet data will reveal longer term trends, and highlight yearly best performance. 

This quarter, the League showed violations have been reduced from four at the start of the League table to one this quarter indicating airlines are moving towards operating best-in-class, modern, quieter aircraft more frequently.

Heathrow-based airlines have also successfully reduced their ’red’ violations by their use of Continuous Descent Approach (CDA) over the same period last year, with LOT and Iberia in particular turning their red scores to amber.  CDA requires less engine thrust and keeps the aircraft higher for longer, helping to reduce noise in arriving aircraft.

The sixth Fly Quiet table rates the top 50 airlines operating at Heathrow (by number of flights per quarter) according to six noise related criteria.  The airlines received a red/amber/green rating for each criterion, as well as an overall score that allows them to understand how they are performing in relation to other airlines.  See Quiet Heathrow
