Warning: not an engineer or mathematics major---

As someone recently corrected me, the preview states that we purchased the 134K MTOW version, which is the higher weight version, if there is such a thing. I just got ahold of some technical publications from Bombardier for airport planning. This is what I understand from that:

The engine types are broken out for balanced field performance. As you would expect, those charts vary based on temp, altitude etc, and there is a different chart for each engine.

Here's where it gets interesting though. There's only one chart for payload range, applicable to the CS100. The engine type isn't included as a factor. For a 134K MTOW, the range-- ISA standard sea level day, no wind, is 2760NM. That's assuming 120 passengers. Ours will be configured for 109 pax, according to the preview. That takes the ZFW down another 2400lbs, using the 225lb pax weight that Bombardier assumes. According to the spaghetti chart, that takes the still air range out to 3100NM. So that's 3100NM for a two class configuration, just like the Bombardier sales literature says.

Guess what? The 1950NM range that the preview states matches up on the chart with MZFW, 111K. Is that a realistic, everyday assumption? Not sure.


Also, what you said about SLC, is part of the reason that it would make sense to base the aircraft there, not on a coast that it needs a fuel stop to make it to the other base... but who says any of this needs to make sense?

FWIW, a ground school instructor at the LGB factory said that we bought the 160k MGTOW MD-88 but only had it certified to 149.5k, in order to save on landing fees. We also had the forward airstair removed and put in storage. These moves could be reversed in order to increase the resale value of the airplane down the road.

It was always interesting to watch the HVP's wait to go down the aft steps and be the last through customs.

LGB being the German toy train manufacture, or who?

Or instead of an inland base with the coasts as outstations, they can have the coasts be bases (LAX, NYC) and the inland cities be the outstations. You don't necessarily need direct base to base flying capability.

Long Beach, CA, but the MadDog does resemble a Lehmann Gross Bahn product in several ways.

LGB was a magical land where they made things not meant to fly, fly.

So what's the actual difference? Just a pencil whip t/o or ldg weight that enables more fuel to be carried? Bigger tanks?

Thanks for the explanation, I forgot about that LGB!

That seems to be true!
