The present used aircraft pricing system doesn't seem to account for C and D checks timing. Example:
See today's DOFM used market (10-Feb-1995), pick B727-200Adv, 19 birds are listed, organize it by age, and compare two similar aged aircraft, say 15 years old, one with almost expired heavy check, the other not:
(a) 15y old, C check expires in less than one month, D check expires in ten months, "fair price to be between 16.1m - 18.9m"
(b) 15y old, C check expires in ten months, D check expires in over 6 years, and... "fair price to be between 16.9m - 19.8m"
Similar "fair price",
But the D check alone costs more than 5m... So the "fair price" should be around 4m lower on (a).Comment:
As long as the book value doesn't incorporate the timing of C and D checks, players will (1) continue to buy planes, (2) used them for 14 to 15 years, and (3) with a few months of D check deadline, dump them in the used market; the end result is (4) no other player will buy or lease them because the planes are wrongly priced, and (5) the player will keep them in the market/storage until they are 25y old or until the end of the game -- all along their own airline value is inflated with an asset that is clearly overpriced.Suggestion:
Planes with D check expired should have an extra charge of insurance
. After all, they are most at risk of catching fire or damaging something with an oil leak
PS: my point being, in real life planes on sale are correctly priced to attract buyers. In airwaysim, they are priced in view of the airline value because of the accounting system set-up (book value = purchased price + depreciation). Therefore, players that have airplanes on sale/storage with expired heavy maintenance checks should be penalized, at present the ones penalized are players that just enter the game and want to have access to normal priced aircrafts.
