DeltaBravo Posted January 22, 2018 Report Share Posted January 22, 2018 Good day. I noted in the downloads section a calculator for a M20E and wondered if anybody has made one for a 'C' model. Quote Link to comment Share on other sites More sharing options...
Andy95W Posted January 22, 2018 Report Share Posted January 22, 2018 FlightPlanGo is a free app that has one. Plug in the numbers and it'll graph it for takeoff and landing. Flightplango also has free charts, georeferenced, ads-b compatibility, and georeferenced approach plates. All for free. 2 Quote Link to comment Share on other sites More sharing options...
carusoam Posted January 22, 2018 Report Share Posted January 22, 2018 Suspect the WnB calcs for the C and E models are essentially the same... for identical years... The only difference will be the individual weights of the airframe itself, which are noted in your logs, or on a loose piece of graph paper from the factory the day your plane was born.... Do you have the original weight and balance details from your logs? Best regards and welcome aboard, -a- Quote Link to comment Share on other sites More sharing options...
DeltaBravo Posted January 22, 2018 Author Report Share Posted January 22, 2018 Thanks for the instant replies. I do have the most recent empty weight figures. At this stage I just wanted to get some indicative figures. Quote Link to comment Share on other sites More sharing options...
carusoam Posted January 22, 2018 Report Share Posted January 22, 2018 The only differences between the C and E are about a 20Lb difference between the Fuel injected IO360 and the carbureted O360. Other things too look for are a change in weight around the 1965C. There was a significant update for the model year. Square windows, fuel strainer, 52 gallons of gas, vacuum driven stair, that kind of thing. PP thoughts being shared, not a mechanic...

Raptor05121 Posted January 22, 2018 Report Share Posted January 22, 2018 I've got one up for my D model in the downloads section, but like everyone says, just substitute your own numbers for it. Quote Link to comment Share on other sites More sharing options...
steingar Posted January 22, 2018 Report Share Posted January 22, 2018 My owners manual says not to put the big guys in the back seats. Its worked for me so far. Quote Link to comment Share on other sites More sharing options...
DeltaBravo Posted January 22, 2018 Author Report Share Posted January 22, 2018 Ha ha Stiengar appreciate the heads up. Just going through the calculations and with full fuel and husband (220 lbs) and wife (143 lbs) up front puts the CofG out of limits forward which is quite surprising. With fuel burn things get better and obviously putting some ballast aft will sort things out so not a problem. Quote Link to comment Share on other sites More sharing options...

Best regards, -a- I think it's closer to 40lbs which is not insignificant. The parallel valve engine is lighter whether injected or carburetted. RV builders prefer the injected parallel valve for this reason. I'd bet the difference in the weight of the fuel delivery systems is negligible.

DeltaBravo Posted January 22, 2018 Author Report Share Posted January 22, 2018 For interest sake actual weight of this particular plane is 1691.8 lbs x 44.31". Quote Link to comment Share on other sites More sharing options...
Ron McBride Posted January 22, 2018 Report Share Posted January 22, 2018 Has your C been reweighed? Seems heavy according to the discussion above. Should be 40 to 60 lbs lighter than my F. My is 1696#'s. this is a continual calculation weight. Quote Link to comment Share on other sites More sharing options...
DeltaBravo Posted January 22, 2018 Author Report Share Posted January 22, 2018 Reweighed last in 2013 and will fall due this year again. Quote Link to comment Share on other sites More sharing options...

I agree yours sounds heavy. My C is only 1607 lbs. including a (heavy) Hartzell 3-blade prop . . . . Quote Link to comment Share on other sites More sharing options...
Yetti Posted January 23, 2018 Report Share Posted January 23, 2018 Interesting note... I picked up a Mooney W&B spreadsheet from somewhere and it had one of the stations wrong. When I put things in the DroidEFB it sorts them via stations. I believe it was the Luggage compartment and the hat rack. I have been doing it on the phone wrong for several years.... Not to my demise thankfully Quote Link to comment Share on other sites More sharing options...

I can put 480lbs in the front seats with full fuel and zero ballast in the back seats, luggage compartment, or hat rack. If I put 120lbs of ballast in the baggage compartment, I can put 540 lbs in the front, full fuel, and be within limits Edited January 23, 2018 by ragedracer1977 Quote Link to comment Share on other sites More sharing options...

My 62M20c is not detectably nose heavy in the conditions you just described. My Cherokee used to get that way with a couple big guys in front, so I know what its like. Either your calculations are in error, or the data on which you've based them. Your Mooney will lift most anything you put in it. You can overload a Mooney, but it isn't easy and someone is going to be very uncomfortable. Quote Link to comment Share on other sites More sharing options...

The limits that I have from the manual are as follows: Most forward 2100 lbs 42"; Forward Gross 2575 lbs 46.5"; Rear Gross 49" Quote Link to comment Share on other sites More sharing options...

I, too, have often put well over 400 lbs. in the front seats, with full fuel, nothing much in the back, and a heavy Hartzell 3-blade prop on the nose. Ain't never had no problem . . . I'll have to dig up my W&B spreadsheet now! Quote Link to comment Share on other sites More sharing options...
Yetti Posted January 24, 2018 Report Share Posted January 24, 2018 For an F model I separate the Front seats since the pilot seat is way on back. Quote Link to comment Share on other sites More sharing options...
