Would something like this dual display pay for itself in a year of operation by saving on maintenance costs associated with the original 1950s avionics of the F27?
Garmin G3X System Dual Display
So this G3X is £6594. Sounds pretty expensive. Is there any cheaper 2nd hand units such as this? The thing I don't know is actually how much it costs to maintain the original avionics of the F27 in the 1st place. Any guesses on that? Pretty impossible to find such figures online.
DOC is per definition operating costs which are directly attributable to the aircraft being operated. The rest are
IOC(Indirect Operating Cost),
DOC+IOC= TOC (Total Operating Cost)
DOC normally consists of four major cost categories ie. crew cost, fuel and oil cost, depreciation cost (including
insurance cost) and maintenance cost.
In your case it might be more transparent to apply the
LCC(Life Cycle Cost, the total cost incurred by an item along its entire life / life cycle)concept,instead of the standard Cost Benefit Analysis (
CBA) methods. the research is focused on aircraft maintenance and engineering, as the main subject !!!
From LCC point of view, all cost categories resulting from aircraft acquisition and exploitation are included in the LCC, only two cost categories are excluded : Ticketing/Sales/Promotion and General Administration cost !!!
The DOCsys formula (for aircraft) has 3 major components. Depreciation + Fuel burn + Maintenance.
We were told as part of the assignment that mods have to pay for themselves within a year or so.
