How long do these routes take Rotty?
Well, for example: on the Billings-Denver run, the first flight departs Billings at 0730, makes ten stops (!) and arrives at Denver at 1316. That's an average of about 1/2 hour for each leg. It's fairly do-able, as most of the airports are above 3,000 MSL and the (unpressurized) DC3 is rarely flown above 10,000 when carrying passengers. But the terrain then becomes a factor on some legs: one has to dogleg around mountains sometimes.
I recently posted a scan of the schedule, and some other stuff, in the "Real Aviation" forum; you might want to check that out.
I've been having a hell of a time meeting this schedule, but I just noticed last night that for some reason this model comes up over 1200 lbs. over GTW every time I start with full tanks; that might explain why I'm not getting the IAS I should ... d'oh!!
Should do better now that I'm shaving some weight off before starting the day's run. But it's still not easy making the hop, taxiing, shutting down, turning around pax, bags and mail, then departing on time.
