KMRY to KSNA real-world routes

SimBrief Dispatch
1

simBrief seems to pick up real-world routes for this city pair, all of which use low airways; as a result, simBrief picks FL170 for a 260 nautical mile flight.

This is rather inefficient (despite the relatively short flight, in e.g. an A320 at half load, staying at FL170 instead of e.g. FL350 – as planned with step climbs unchecked – costs 5 minutes and 350 kg of fuel – roughly 10% of the flight time and 16% of the trip fuel at the latter altitude).

…seems to suggest the default route offered by simBrief:

SNS T259 AVE LHS V459 SLI

…is flown between FL210 and FL250 despite the presence of said airways. Unlike europe, I’m not sure the airway restrictions are binding per se.

Perhaps equally importantly, both the IFR route analyzer above and ftlplan.com suggest the most common route between these two airports might be:

MRY5 MRY BSR LIBBO TILLT TILLT2

…at FL270 or higher; but that one’s not listed as a real world route by simBrief at all.

In this case it makes sense that it would get added, but also, why didn’t simBrief pick it up when SkyVector, FlightAware and fltplan seem to know of it?

Thanks Tim, should be fixed now.

It’s because MRY5 MRY isn’t a valid route segment. Despite the FAA’s official chart name for the SID being MRY5.MRY, no MRY navaid exists around this airport. Which meant the route was being judged as invalid and therefore wasn’t getting added to the database.

I’ve had to add some special handling for this case, it should be fixed now.

Cheers,

Ah yes, that would explain it. Thanks!
