From OWE per seat ... to Fleet Yield per 24h ?

Hello folks ! The discussion here is driving fleet strategies and route marketing policies at airlines round the world ! Thanks Gilles !

But I recommend :
- to break aircraft types into sector type categories (RJ, feeder, VLA, WBMH, WBLH ...) and do segment analysis ... otherwise we are comparing all Y-class types with three class types or apples with bananas
- to look closely at the respective types' groundworthiness ie airport turn-around time, to compute 24h productivity : an A321 @ 218 pax turns around eg in 41' whereas its sister H21QR turns in 24'5 or 16.5' less, with 199 pax. OWE/pax are apprx. 236 kg vs 221 kg, but H21QR can take 6 AKH with payfreight on top of 4 AKH with checked-in luggage, against only 3 + 7 AKH for A321 so at the payfreight-to-pax revenue contribution conversion factor, the capacity of H21QR is 199 maindeck pax plus 6 x 10 = 60 other 'virtual' (underdeck) pax, total 259 'aggregate' pax (OWE = 181 kg/pax), which compares with 194 kg/pax for A321.

We can conclude that measured on Gilles scale - reinterpreted to include lower deck, H21QR is more efficient than A321 ... but there is a lot more to come enlargening the scope to 24h yields ... the perspective gets wider as you go through all the ingredients one by one to construct 24h-yields !
