M20E Performance Charts (Recreated so that they are Legible)

[Matthew P]

Well, my eyes are going and I can barely read the (copy of copies) performance charts out of the POH , so I had some down time and decided to recreate the performance charts for the aircraft (attached).

Hopefully there are others that can use them, even though virtually everyone uses an EFB that has the performance date on them...

I retyped the relevant portions of my Performance Tables when I was creating checklists as a new owner. The 172 all fit on a single sheet of paper (normal on the front, Emergency on the back; each was three columns in landscape format), but I couldn't even fit the Mooney into a sheet of legal paper front and back, so ended up with a booklet and many empty pages.

The last three pages are Performance, covering 2300-2600 RPM, two altitudes per page. It's right handy on my kneeboard, even though I've pretty much standardized on three settings anymore (23/2300; 22/2400; WOT-/2500) depending on altitude. 

You'll be surprised how nice it is having then for easy reference when you fly.

I can, but nothing in my C will be the same as your E.

Those charts are gorgeous.  That's a lot of work.  Thanks.

It is interesting to compare these numbers for your 1966 E-model with my 1970 (also E). Quite a difference! For example, at 2500 feet, all out, 2200 lbs, my POH lists the top speed of the plane as 186 mph, while yours is 197. Moreover, it seems like in 1966 they would still allow best power mixture at 97% BHP (13.8 gph), while in my plane they want full rich anytime you are over 75% power (18.2 gph in this setting).

I wonder which of the two speed numbers are closer to reality. I have heard many say that the numbers were inflated by the marketing departments. Presumably more so in 1966 than in 1970, but it is still not clear to me how realistic the 1970 numbers are still.

Of course marketing inflated the numbers, that’s what they do.  If we all believed what the marketing department was throwing out there, we would sell our Mooney’s and buy a Cirrus.  They have this remarkable system that will save everyone on board.  Oh wait the parachute was a necessity due to its inability to recover from a spin.

Shhh.  There may be wives reading this forum.

Impressive work on Excel.  I used for Excel for years and never knew it can look this good.

Thanks...in the process of making a complete checklist to include all charts and useful info to tie everything into a single document that can be printed out in a 5"x7" spiral bound booklet...not really necessary I recon, but I have time to kill with all this non-flying weather
