RobertGary1 Posted February 24, 2022 Report Posted February 24, 2022 Never understood why Mooney forgot to provide performance data in the teens at least in my 76F. I commonly fly at those altitudes. Foreflight just throws up it’s arms. Quote
Mcstealth Posted February 25, 2022 Report Posted February 25, 2022 I do that...throw up my arms Quote
PeteMc Posted February 25, 2022 Report Posted February 25, 2022 (edited) If you go into your aircraft's profile, do you not have the option to +Add Basic Performance Profile? It may not be there pending which FF subscription you have, but if it is there, you should be able to add performance date up to your service ceiling. You may have to make it/modify it as you go, but at least FF will try and calculate something. Edited February 25, 2022 by PeteMc Quote

Start collecting your own data…. Share with your MSer friends… You will end up with more data than Mooney was able to collect back in the day… The turbo manufacturers want you to believe that your Mooney is unable to reach the oxygen levels…. I’m sure Mooney would have preferred their customers to go to the next level… M20K… There is so much overlap… Mooney expected everyone to not fly with such great precision… Best regards, -a- Quote

Yep, what @carusoam said... Just start looking at the numbers you're getting on your flights. If you wanted to start with crunching numbers. Get the numbers for the E and the J and see what percentage they change with altitude. Then compare those numbers to the numbers you do have. From there, look at the F & J above whatever the last numbers you have for your F. Again, use those numbers as a guide to calculate numbers to plug into ForeFlight. After you've got the numbers in FF, go fly and see how close they are. Regardless of temps, winds, etc., FF is calculating how it thinks your plane will perform in those conditions. So if what you're really getting is off, tweak as needed until you're happy with the numbers. 1 Quote

Actually now that I think about it I think between Garmin and jpi all the numbers have already been figured out is just need to write them down. Quote
carusoam Posted February 25, 2022 Report Posted February 25, 2022 The JPI becomes an incredibly powerful flight data collector… with a GPS and FF sensor connected to it…. Taking winds aloft into account… you may want to add a few three way courses into the mix…. Specific to your data collection project… If you have a modern airspeed instrument…. Does the JPI collect that data as well? The Garmin engine monitor and flight data recorder is really next level for gathering this type of data automatically…. PP thoughts only, not a CFI… Best regards, -a- Quote
