Land development in the vicinity of airports often leads to land-use that can attract birds that are hazardous to aviation operations. For this reason, certain forms of land-use have traditionally been discouraged within prescribed distances of Canadian airports. However, this often leads to an unrealistic prohibition of land-use in the vicinity of airports located in urban settings. Furthermor...
On airport runways, blue light fixtures denote taxiways between the runway and the airport terminal. Blue optics transmit mostly short-wavelength radiation, which makes traditional incandescent lamps a poor choice of light source; the resulting fixture efficiency could be less than one percent. LEDs are replacing incandescent lamps in this application. But unlike incandescent sources, LEDs do n...
A mixed integer linear program is presented for deterministically scheduling departure and arrival aircraft at airport runways. This method addresses different schemes of managing the departure queuing area by treating it as first-in-first-out queues or as a simple parking area where any available aircraft can take-off irrespective of its relative sequence with others. In addition, this method ...
Multi-Temporal Interferometric Synthetic Aperture Radar (MT-InSAR) techniques are gaining momentum in the assessment and health monitoring of infrastructure assets. Amongst others, Persistent Scatterers Interferometry (PSI) technique has proven to be viable for long-term evaluation ground scatterers. However, its effectiveness as a routine tool certain critical application areas, such millimetr...
To provide a context for the potential threat of unmanned aircraft systems (UAS) sightings on airport operations, this paper compares characteristics UAS with two common threats: wildlife strikes and runway incursions. This study analyzed over 60,000 events in three-year period (September 2016 to August 2019), including 6,551 from Federal Aviation Administration (FAA) Sightings Report database,...
