TL;DR – version v0.4r22 of the FlightView app is now available in TestFlight. It fixes a bug with the RPM counter and adds an engine data logging feature.

Quick Fix

Well, that was quick. Last night I received a bug report that changing the “Ignition Events Per Rotation” value (i.e. the number of pulses the EMS receives for every full turn of the engine) failed to update the configuration on the FlightBox Pro. Turns out that one letter in one parameter name was capitalized, so the code on the FlightBox that receives the update silently ignored that value. Computers… so picky.

Engine Logging

v0.4r22 adds engine data logging. The logs capture a 1 Hz (once-per-second) history of the engine values as reported by the EMS. Note that the current version assumes that the inputs on the EMS are […]

I am pushing out v0.4r21 to TestFlight with a set of fixes to issues uncovered in the past week. This version requires the same FlightBox firmware as the release last week (v2.3r1-7121b8ce98), so if you’ve already updated your FlightBox Pro EXP all you need is the new version of the app. (If you’ve not updated to v2.3r1-7121b8ce98 the app will prompt you to do so – see last week’s blog post for details on the update process.)

The two users who discovered this issue had the unfortunate experience of having the app crash every time that METAR arrived (about once every minute). Fortunately the next refresh from the METAR site was properly formatted and the crash stopped […]
