International Journal of Engineering and Information Systems (IJEAIS)   Year: 2020 | Volume: 4 | Issue: 10 | Page No.: 3-6 Modeling of Commercial Aircraft Elevation/Climb and Descent Angles at Regular Rates and Ground Take off Speed Amupitan Martins A, Olabimtan Olabode.H & Ashraf Mahmud.R Abstract: This offers a specific approach with mathematical and environmentally safe air traffic operations, with a possible alternative. In particular, the models should be more predictable for air traffic controllers, provided that the proposed procedure follows an assigned flight path angle, with the aircraft steadily declining towards the runway perimeter. Essentially, these proposed strategies are expected to contribute substantially to minimizing the use of aviation fuel and assisting air traffic controllers in controlling the simultaneous allocation of operation time. Ten elevation and descent gradient angles (100-1000 ft. /km) were simulated at a constant climb/elevation and descent rate. With the rate of climbing and descending, descending, and ground speed of 740-930 km/hr. at 500ft / min. Two linear models of y=59.092x-8.289; R2=0.998 generate by the interaction of the elevation and descent gradient in feet per kilometer and the estimated angles of elevation and descent in degree and y=32.811x-0.0437; R2=1 by the elevation and descent gradient in feet per kilometer and the climb/elevation and descent grade in percentage. The models are expected to be practically explored for further recommendations for the future of the aviation industry across the globe.
