I initially took a bit of time to get my mind around how they system works and I am still a bit unsure. The best bit, the through briefing pack, The worst bit, language whilst in English seems more like an English translation of German There are some interesting variations of aircraft profiles, not much looking like their POH numbers. The most pleasing bit was getting my Squawk through on my outbound, about 30 minutes before EOBT as a text message which was helpful and provided confirmation I was in the system, The most frustrating was not getting the inbound Squawk until after I had landed at my destination. The text message arrived in the inbox 10 minutes after takeoff, which was not a lot of help with having confidence of being in the system. The only other downside is that with the U.K. GAR, there is no facility to easily cancel a GAR whereas OnlineGAR, either as a standalone product or as part of Skydemon does allow you to forward a cancellation and receive a cancellation receipt as well. This make it more flexible than RR in that aspect. So adding the pros and cons together, it's ok but I prefer to file by AFpex as I get the confirmation of being really in the system directly and have control. Unfortunately IPad and AFpex don't work together yet.
