Flight trajectory fuel efficiency on short segments: AUH-DOH (Abu Dhabi via Doha)

The work substantiates the strait in runway approaches LOC CDA R13 and VOR CDA R31 with manipulation of BADA total energy equation using ICAO rule of thumb for fuel burn reduction. This case study of fuel efficiency by flight trajectory on a short busy route DOH-AUH as proof of theorem of earlier study findings (Cao et al, 2011; Marla et al (2011) After the application and analysis of four default equations and values on fuel reduction, the application random between upper and lower limits defines a fuel burn reduction of 219 kg for each descent trajectory for flights DOH-AUH. A graphical representation of this is seen on the Fuel Reduction Chart. Annual fuel savings come to 696 538 kg, using the flight distribution schedule of Qatar and Etihad in the Abu Dhabi International Airport. The corresponding emissions reduction on CO2, CH4, N2O, NOx, CO, NMVOCs and SO2 are also stated. Subsequently, in a short route the fuel burn in a descent trajectory represents a larger portion of the flight expenditure. The fuel burn in the descent trajectory for each flight en route DOH-AUH, constitutes 6.4 percent of the total fuel consumption and is not typical to the design range and standard payload that derived for long hauls.
