What is your mission?

Distance?
How much weight in the cabin?

Remember; the easiest way to improve your block:block speed ... is being able to skip a fuel stop.

I remember reading this article in Flying in the late 80's. Maybe it'll help in your decision making.

The correct answer to that binary question is : A36

Need TKS already installed. A36 is out of my price range. Is the mooneys useful load of 900 pounds seems low. After filling the tanks you're talking about 460lbs for adults and luggage? My wife wieghts 90 pounds which helps lol.

900lbs is good for a 200hp plane. If you need to lift more you will need a bigger engine.

What kind of TAS can you plan on in the non turbo 210L/M?

I have seen up to 175 KTAS when alone and light in a C210N at 7,500 feet. The 210L/M should be basically the same. It's more realistic to plan for 165 KTAS.

Is youre the 285HP or 300?

I don't think it matters. The fastest speeds for a normally aspirated Cessna 210 are attained at altitudes where you are getting perhaps 22 inches of manifold pressure and likely running at 2500 RPM. The 300 HP engines I believe have a 5 minute limitation for running at maximum RPM, the reduced, continuous RPM maximum RPM gives you 285 HP.

Note I have less than 35 hours of experience on normally aspirated 210s versus about 1,000 hours in P210s (various P210Ns and the P210R).

and mo money

I was seriously considering a M252 Last year, until I learned that the Useful load with full fuel was in the neighborhood of 350-400lbs

190kt cruise was sure tantalizing though. Would just have to mail my children ahead of time.

that's kinda misleading though...

My 201 has 100 usable or about 1800 mile range. 60 gallons get's me in the 1100 mile range.

That being said, an A36 is a much larger interior plane with more people options.

Charles, Not that 10hp is a big deal but the M20K carries a TSIO-360-GB or LB is a 210 HP engine (6cly). The M20Js are IO 360 NA engines. And I agree that the Mooney have decent payload for their HP. They also have excellent range, baggage for 4, not so much.

To the original question and comments, Its fun the hear real world numbers on aircraft but like many comments stated...mission, and budget are the main drivers. This was positioned as "vs" question and the 210 and 20K have different strengths.

I think an old ovation would compare a little better than a 231/252. The airplane decision is up to your needs. The mooney interior space is not bad. It's not the roomiest feeling but it's because of how you sit and where the panel is. When I sit in a mooney I like that I don't have to lean forward to reach anything on the panel. I personally think the mooney is a better airplame Thant the 210. But hauling four 200 lb guys a 210 would be better..


P.S. Why not a nice A36?
