Performance data of Expedition E350 aircraft

Expedition E350 POH Takeoff distance calculator

Here’s a cool thing I created. I hope you like it. It’s a Takeoff distance calculator for the Expedition E350. Note that its based on data that will supposedly appear in the POH, but since I haven’t actually gotten my plane yet, I haven’t seen its final official printed POH, so there might be differences.

Also note that the calculator “estimates” and “interpolates” the results based on formulas that give “approximate” results. Those estimated results won’t exactly match the exact data values that appear in the tables in the POH, but they’ll be reasonably close.

Legal Disclaimer: I made this for my own personal use, to make it convenient to calculate these takeoff distances. It’s possible I made mistakes in programming it. It’s possible that it can be used incorrectly or misinterpreted. Therefore,
if YOU use it, it is entirely at your own risk. You should always verify the calculation results with the actual POH tables, to see if they agree.

You don’t need the internet to use it. You can "Save As" (the calculator page), choosing "webpage, complete" and it will save a local copy of that webpage onto your laptop, and you can run that local copy from your laptop, without needing an internet connection.

Performance tables, from the POH

Landing Distance	Takeoff Distance	Climb – Time, Fuel Distance to Climb

Cruise at 2000 ft	Cruise at 4000 ft	Cruise at 6000 ft
Cruise at 8000 ft	Cruise at 10000 ft	Cruise at 12000 ft

		With the above Cruise settings, it will fly at 150 KTAS at -20 C and at 160 KTAS at +20 C at around 7000 to 8000 ft, and consumes about 19.3 GPH.

What is the cruising speed?

I think my true airspeed, when I’m around 8000 ft altitude, is about 140 knots. When I’m at 10,000 – 12,500 over the mountains, I think it’s about 125 knots.

Fuel burn?

Over the mountains, its about 13 gallons per hours. But when I’m making local short trips over the prairies at 4000 ft, it’s about 18 gallons per hour.

So your numbers are a little different than the offical numbers in the Pilots Operating Handbook.

Yea. In my early days with the aircraft, I was always running too rich, because I didn’t really know my peak temperatures. And regarding air speeds, when cruising over the mountains for 4 hours, my propeller angle (and therefore manifold pressure) is set fairly simplistically at 25, which may not be to maximize speed, or minimize fuel burn, it’s somewhere in the middle so that if I go up or down in altitude in the mountains (into valleys or over clouds), I don’t need to worry about the prop.
