• Apple released it's annual update - iOS 17 for both iPhones and iPads. After preliminary testing we see no issues with both Logbook Pro and APDL on iOS 17. We will continue our thorough testing with the public release and follow up should we find any issues.

Summary Garbage Collection Error


New member

Any time I try to do a summary I get a garbage collection error with the message: System.InvalidCastException:Could not find resource assembly. So what does that mean and how can I fix it.
From your PDA please tap (Settings)(System) and (Memory). Tap (Stop All).
From your PDA please tap (Settings)(System) and (Regional Settings). Please
let us know what the shortdate format is set to. Then change it to M\d\yy.

Re-run the AirlineLogbook program. Test the crewrest page.

If the error re-appears please, check the "General" preference page and make
sure that "YTD Starting Hours" is set to H.M and not HH:MM. For example 72.3
is ok, 72:13 is not.

Fly Safe!
