Based on some recent issues with how some of our flight
instruments record flights, a working group was established a t the CIVL plenary
in February 2017 with the task to better define what is required of our
competition flight instruments. The output from this working group is the ‘"CIVL
Flight Recorder Specification" that will be discussed and voted on for
acceptance at the 2018 plenary. The overall objective of the specification is to
keep things simple and realistic while defining the requirements of a top -
level instrument or logger. Additionally, the approach has a method for acquired
approval (grandfather rights) for existing instruments as the new specifications
are implemented.
