Twin-jet and trijet aircraft: a study for an optimal design of regional aircraft

Transportation Research Procedia, 2018
Abstract Aircraft with three engines, as known as trijet became a standard design among manufacturers after 1964 when the FAA’s 60-minute rule was established for these aircraft. This regulation restricted the flight path to 60 minutes’ flying time to a suitable airport, therefore affecting the operation costs and limiting the range of twin-jet ...

Eastern asian emissions of anthropogenic halocarbons deduced from aircraft concentration data [PDF]

, 2003
The Montreal Protocol restricts production of ozone-depleting halocarbons worldwide. Enforcement of the protocol has relied mainly on annual government statistics of production and consumption of these compounds (bottom-up approach).

A Global Methane Observation System to Reduce Uncertainty for Anthropogenic and Natural Sources and Sinks for Detecting and Attributing Climate Feedbacks

Advanced Science, EarlyView.
Conceptual illustration of a Global Ecosystem Methane Observing System (GEM‐OS) integrating satellites, aircraft, atmospheric networks, and ecosystem measurements to quantify methane emissions from anthropogenic and natural sources. The multi‐scale observing framework improves source attribution, reduces uncertainty in regional methane budgets, and ...

Radiative forcing from aircraft NOx emissions: Mechanisms and seasonal dependence [PDF]

, 2004
A chemistry-climate model has been applied to study the radiative forcings generated by aircraft NOx emissions through changes in ozone and methane. Four numerical experiments, where an extra pulse of aircraft NOx was emitted into the model atmosphere ...
