I just got the announcement email, so I decided to play around a little.
Tried to enter a Piper Arrow. Put in P28R/G as the type. No go. Tried P28, which seemed to make the programmer happier.
Added enough data to make the programmer completely happy, created the airplane record.
Went to add performance, but no pre-stored performance was shown.
Did more or less the same thing with a 172, called it a C172, and got a match on performance data.
There is apparently no way to know, when performance data is not offered, whether it is not offered because it is not there or because I have not correctly guessed the syntax of a type designation that will match. PA-28R-200? PA-28R? P28? PA28? P28R? I don’t have the patience to engage in a guessing game with the programmers.
Ideally, there should be a pick list that contains only designations that will make the programmer happy.
