Foreflight performance data for Tsi
Posted: Fri Feb 12, 2021 7:07 am
I've been doing a little dream flight planning until my Tsi kit gets here (and built) and have noticed that the flight profile for the SlingTsi caps out altitude at about 9,000MSL. Even if I create a from-scratch profile. I was a bit confused as to what the limiting factor was with this, so I emailed Foreflight to find out. This is what they responded with:

It would be nice if the profile that is in the performance data reflected the published service ceiling. Not sure if that is something that could get updated easily or not. I didn't realize how tightly that information was through Foreflight and the manufactures.ForeFlight imports performance data directly from the manufacturer. The performance data available is what limits ForeFlight's ability to select cruise alitdudes. For example, if you reference your performance charts and the performance data stops at 9,000', ForeFlight will not be able to plan above these altitudes with this performance profile. Essentially without the performance data from the manufacturer, ForeFlight is unable to determine cruise speed/fuel flow to display how wind will affect it.
ForeFlight does not "interpolate" performance results for the purpose of providing performance data at higher altitudes. If you have performance charts with more information, please provide them and we'll take a look.
