摘要：

Worldwide increases in commercial air traffic have raised concerns about the effects of aircraft emissions on the atmosphere. The purpose of this study was to demonstrate the capability of a remote sensor, developed for the measurement of automobile emissions, in measuring nitric oxide emission indices from in-use aircraft an the ground without interfering with their normal operation. In two days of sampling at London Heathrow Airport, a total of 122 measurements were made of 90 different aircraft in a mix of idle, taxi-out, and takeoff modes. Aircraft measured at idle exhibited little nitric oxide emission. Emission indices measured from aircraft at higher thrust levels were not inconsistent with values from the ICAO Engine Exhaust Emissions Databank.
