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 ...
