Anybody with a good handle on direct costs (purchase and fitment, but not lost flight hours) and payback period with oil at $60/barrel and 1500-mile stage lengths for a 757? (Or other example.)
I wouldn't say I have a good handle, but I can give it a shot!
The 757 burns approx 3000-3200kg/hr over distances on average of approx 1000nm according to previous statistics provided in this thread viewtopic.php?t=569157
The Aviation Partners Boeing site has some really interesting info about their products worth visiting here http://www.aviationpartnersboeing.com/p ... 57_200.php
including a graph showing fuel burn savings of ~3.75% over 1000nm.
If our theoretical 757 flew three x 3hr sectors a day, it could save something like 370,000kgs of fuel per annum. That's 3000kg x 9hrs x 365 days.
The 757 blended winglet kit (parts only) retails for $1,120,000 USD, so if fuel continues to hover around $76 a barrel/$600 a metric tonne, an operator could save around USD$220,000 a year in this scenario and have the winglets cash positive in 4 years.
If utilisation was increased to 12hrs per day by adding another flight, vs the 9 in our scenario, and fuel increased to $100 a barrel, the savings turn to $390,000pa.
If flight time increased to take advantage of higher savings, ie two six hour sectors per day and $100 a barrel fuel, one could save $470,000pa. A cash positive investment within 3 years, quite impressive.
Very back of the napkin math here!
