Measured noise reductions resulting from modified approach procedures for business jet aircraft [PDF]
Five business jet airplanes were flown to determine the noise reductions that result from the use of modified approach procedures. The airplanes tested were a Gulfstream 2, JetStar, Hawker Siddeley 125-400, Sabreliner-60 and LearJet-24.

The long term evolution of vertically-related industries [PDF]
The paper develops the argument that the long-term structural evolution of an industry depends on the evolution of a vertically-related, downstream industry. We analyse two pairs of vertically-related industries, the jet and turboprop aircraft and engine
