Wind-Effective distance
« on: October 09, 2019, 02:47:23 PM »
Dear Sami

I read manual and changelog.

Can you advice what else parameters (except still air range) I should take into account while trying to predict what effective range AC can fly?

why I was confused:
GW2 Seoul-Madrid 5383 nm range
Equal still air distance = 6170.

DC8-72 (Nominal still-air range   5560 NM)
can carry 112 PAX from 160 at Seoul-Madrid leg

B762ER (Nominal 6700 NM)
can carry 109 PAX from 210 at the same leg

It is really difficult for me to understand - why ?

if you are referring to the yellow infologs in the route planning: those are not always for the "best" configuration of the aircraft.

may be it will be more suitable to redone it so it will show limits for "best" configurations of AC ?

I already posted a feature request for that:

I think showing the pax uplift with the lowest possible configuration is lesser risk scenario than the other way around.

If the system would show, for example 150 pax out of 210 for the best configuration, someone who has bought a 767 with the lowest configuration from UM would have no clue what to expect from his bird. Will it carry 120? or a 100? or 70? The economics of the route will vary wildly when we get to those extremes.

The current system gives the least amount of pax that any 767 can possibly carry, which is fair in my personal opinion.

If you don't have a 762ER in your fleet (which you can't as of now) it shows limits for the lowest available MTOW variant so that figure is wrong. Once you have 762ER in your fleet that number will reflect the lowest MTOW variant you have. The 6700nm 762 ER variant will make about 6400nm westbound unrestricted, an example being YVR-DXB in TMT for me, 6334nm and operating unrestricted in both directions.
