  1. Thanks for the tip @flyingcheesehead I haven't tried that option but will give it a try. regards PatrickF
  2. You're right there is a fair bit of asphalt on the taxiways but it's not as flash as it looks in Google Earth ! Some of the grass is pretty rough too. We've had a number of conversations and would much rather be on a long bitumen strip. One of the big worries is how those fuel tank seals like getting regularly shaken on the grass. regards PatrickF
  3. All good @steingar - you may have missed it - we have another 4000 ft of grass after the tar before we get to trees. Just a fun challenge to get off and avoid the bounce on the grass ! regards PatrickF
  4. @carusoam - Crossed info - we are at sea level (40') at YCAB ! 800 foot of tar is just enough to get off if I'm solo with about 25 gallons on board - and not much else. And the sea breeze is usually good for a few kts. Grass at 5000' - now that would be a different game ! One advantage we do have here - we are pretty flat. I did the calc at 5000 to check my numbers against yours for the grass chart you have and it seems to match pretty well - which gives me some confidence on the factors quoted on that web site. regards
  5. We operate a long body O2 off grass in Aus. A lot of Mooney guys here would -the tar strips can be few and far between. No real issues except you do lose elevator authority when you get slow so need to get it right first time and catch the mains to look after the front. We have 800 feet of tar on one runway (YCAB) which we take any time we can. Can get off one up and light without using the grass but haven't managed to land on it yet ! I don't have any grass numbers in our POH so when I was doing my XL sheet I used these factors for ground roll - once you are off it doesn't matter: - I'd stay away from the long wet grass Anthony @carusoam my numbers come out to close to your book for short dry grass - certainly within the margin for error for the graphical/fat finger method !

  6. Guys, I can't argue with X-plane and I've heard it's good. I was too invested in MSFS to change. Since I started flying in '97 (MS95?) I've tried to get a copy of any new plane I've flown, customise as much as I could, and check the basics. Certainly helps with rough numbers and panel layouts etc. Because I was tied to the MSFS world I jumped over to Prepare3D from Lockheed. It is very good and getting better, and I got to keep all my work. For anyone flying Garmin GNS or GTS I can't recommend RealityXP : too highly - they have an Xplane version as well. Since we bought OVH I've put a bit of extra work to get the sim model as close as I can. This model is a stock P3D Acclaim modified with Mindstar G1000 and RealNAv data, custom performance data and custom textures. As real as it gets ? When the weather is really ordinary I just put in some IFR time at home. Practicing button pushing on the ground in the sim is a lot cheaper than burning gas. The instruments and add on GPS simulators are very good now. My full setup is probably less than 2 AMUs. The real trick is not to geek out too much and make sure you fly rather than fiddling with your set up - a challenge I occasionally fail!
  7. I like where you are heading here @carusoam - start with the book numbers and check against reality given the info we now capture. It was something I remember doing with the instructor in the C150 on about my 4th hour - check short field takeoff against the book. We used the cross runways and taxi entrances as the check points. Having said that a 150, 2 up, in summer in Canberra at 1800 ft elevation gave us plenty of time to check the lift off point ! You've prompted me to check the M20R against the book more carefully. We have a cyclone off the coast so no flying this weekend but I've done a quick desktop check. Our home strip YCAB only has 250m (780ft) of tar before the grass. If I'm one up and only 30 gal of fuel I can just get the wheels off before the tar ends (without doing a static full power, release brakes etc. short field takeoff). The book number on a typical day with 5kts of head is 628 ft. Given that I probably waste 40 ft rolling on and 50 ft with the rolling "soft start" the book numbers look close but a bit wishful - you'd want a good margin on these. PatrickF
  8. Guys, just caught up on this one. Thanks for the heads up @carusoam @midlifeflyer I am happy to generate a set of "Cessna style" tables. Will be pretty easy to pull automatically out of my sheet, and you are right they would be useful. My sheet just does the calcs on digitised versions of the charts, and draws over to confirm visually that results make sense. It is at least as accurate as doing it with a pencil, or thumb. I am working my way through the various models but am way behind on my promise to complete the set - dam work. I've just looked at the POHs I have and my M20J one has the table version rather than the chart. I've attached. Is it an earlier version ? PatrickF
  9. @Awful_Charlie That sheet looks in great shape, I'll cross it off my list. regards
  10. @laytonl Lee, thanks for the shout out. You beat me to it! I have a work in progress J version of my excel sheet and Open App using the same technique as the M20R one. I picked the J as one I had to do on the basis of how many are out there ! - and here in Aus. Have others in various stages as well - gets easier as you reuse the code. @Deb Debbie & David have been unbelievably thorough and helpful with some very detailed beta testing and feedback on the original XL sheet and App. The M20R App changes are live and I'll issue the final updated XL sheet with the rest. @mike_elliott also had got me POHs for the new models and I'm working through them - a fair bit of cross over between models which makes it easier. @carusoam - Anthony - I have a working version of your 310 STC option including the power charts. Just got to smash a couple of pesky bugs. @Awful_Charlie has sent me the charts for the M20M so it's on my list as well. Intention is to get them done as a job lot so I don't do multiple posts but keep to the concept ( in my case) of providing a simpler way to pull book figures (and cross reference original POH charts) Now if I didn't have to work to pay for the Avgas these things would happen quicker ! PatrickF
  11. Harden up Mike - you should try it with 4 kids ! Great to see you out in Aus
  12. Robert, agree - ours doesn’t either ! The aim of my sheet was to make pulling numbers from the POH charts easier to do if you need to and as a cross check. The app does the same thing. Perhaps if I add a % adjustment to the book number that you can leave set, or change ( like I have in the take off/ landing distances) Suggestions welcome. Sorry for the delay -we have our PSP program this weekend in Bathurst NSW. I was doing my homework. Regards
  13. Mike, Saw that one drop on Friday. I think I'll leave that one for the OzRunways boys! You have prompted me to add a disclaimer. I've done the spreadsheet as a way to go back to the POH for a cross check, or the app to do those quick checks. The EFB guys do a great job of the detail planning. Look forward to catching up next weekend. Have a good flight over.
  14. Guys, I’ve made a couple of minor updates to the XL sheet - fixed an error in the off chart ROP MP calc and added QNH in inches for you guys on that side of the big pond. I have been looking at the easiest way to get the info onto a mobile device in a usable form. It was going to take a long time to write, or have written, a native app but I’ve found a clever site from our German friends that allows you to port an XL sheet as an app “wrapped” in their App. Try this link. Should work. Haven’t checked but understand it works on Android as well. The first time you click it will ask you to install the OpenAsApp app. Then it should give you an option to open the sheet. Let me know your thoughts and any bugs. Should work well for those quick “how much fuel can I load “ calcs as well as landing/take off distances. Fits on my iphone SE screen so should be better on larger ones. Sorry no charts. Once you have input your own values including BEW and arm use the menu accessed from the top right to save for future. You'll want to change the BEW - ours has AC and Oxy! All sheets take values from the loading on the W&B page unless you input an alternative fuel load, or weight. Apologies but you guys will still have to input load weights in metric. Might do an imperial version if enough are keen. If you are running ROP input values into the LOP page - they are carried to the ROP page. As before happy for any suggestions, or bugs. For the app any changes I make are "pushed". Happy to cut a version for other aircraft now that I have it set up - just need some clean charts, and some time. PatrickF M20R_WandB_PerformanceCharts_rev2.2.xlsx
  15. Thanks guys, hear you on the ios App - me too! I haven't coded in ios but know a few who do so will have a look. With the maths done coding to get the numbers would be trivial for someone who knew what they were doing - look and feel, graphs and pretty pictures are a bit harder I'm sure. Must be an Ovation driver over there somewhere who made their $ writing Apps ?
