Seriously? If you want fun, go buy a Carbon Cub. I don't see a DA62 as being a "fun" alternative to a turbine, unless you like paying the same and getting less.

Isn't that what makes aviation great? Everyone has a different idea of fun, and we have choices among those fun things. Celebrate the choices, be happy that we have those choices, and pass them along to the next generation.

It's "glider think". Likely will bankrupt the company. I will predict that Cirrus....err...Diamond won't sell any of the SF50....errr....DA50s.

I'm a card-carrying Diamond fan, and I'm also scratching my head about who is going to buy this aircraft. Other than being really nice to ride in (which is no small thing), I don't see a compelling reason to purchase one. It needs more speed and range (or a different pricing strategy) to be competitive.

Diamond has something like an 18 month backlog of DA62 and DA40NG orders, so I think it's a bit early to predict that it will go bankrupt anytime soon. The cynic in me thinks they've priced the DA50 so high because they don't have the production capacity to sell (m)any of them at this point.

I am completly baffeled as to why no one can bring to market a Light GA aircraft that is more efficient than the Columbia 300 that was certified in 2000.

175K TAS @ 12g/h giving a range of over 1,000NM (110gal)

or

195K TAS @ 16g/h giving a range of over 1,000NM (110gal) for the Columbia 400/Ttx .

This DA50 does'nt even come close.

Michael, how much load can the Columbia carry with enough fuel to fly 1000 nm?

So I just pulled up the range chart from the POH for the 400. Most of the 400's hold 98 gallons of fuel.

Fastest at lowest 1000nm is available at 55% power, 13,000' with full fuel. Range and speed are better the higher you go, as it is certified to FL250.

My particular aircraft has an empty weight of 2519.3lbs including POH, cabin equipment, oil. Maximum takeoff weight is 3600lbs. Top it off with 588lbs of fuel, that leaves 492.7lbs of payload. That includes fuel and time to climb, descend and IFR reserve.

Cruise performance table shows 185kts true at ~13gph at -50F lean of peak.

Reduce to the most economical cruise at 45% power, you get 172kts at 11gph at the same altitude, so basically another ~60 pounds in exchange for another 25 minutes in flight.

Maximum range is 45% power at FL250, 1150nm, 206ktas @ 11gph, with full fuel and 492.7lbs of payload. (includes fuel and time to climb, descend + IFR reserve)

There's no ZFW.
