Hi Mariko,
I have downloaded the App onto my Galaxy S9+ then spent some considerable time working out how to use it.
I was initially confused until I realised that you need to download two maps for each country - a Base Map (to show the terrain) and an Aviation Map (to add airfields, controlled airspace, airways etc.).
I have an issue, however, with the fact that the UK Aviation Map has some fairly obvious ‘gaps’ in its selection of airfields - with several that I fly to not present - which complicates Route creation considerably. Also, while airspace and airways boundaries are shown, the altitudes of each area of airspace can only be checked by clicking on each individual airspace area - which brings up a temporary ‘what’s here’ type report. I suspect this could prove difficult in flight on a small screen!
I also found setting up routes difficult - especially where waypoints including airfields aren’t present and have to be added manually. Whilst completed routes can subsequently be saved for future use, I can find no way to permanently save user added waypoints such as airfields, individually for future re-use, which is very frustrating. I was also unable to quickly adjust a ‘preliminary’ route to avoid a hazard zone by ‘rubber-banding’ to a new ‘user created’ waypoint as creating such a waypoint always adds it onto the end of the existing route as an extension, not an insertion in the leg you are trying to alter. This can be manually adjusted, but that requires going into the route settings and manually ‘re-ordering’ the waypoints to place the new one in the correct sequence - which is definitely not user friendly. I was however impressed by the option to run the App in ‘North-up’ or ‘Track-up’ Mode.
The App can as you report be used to display traffic from PilotAware, with colour changes depending on proximity, though I was unable to test this extensively due to lack of traffic locally.
Although, as you say ‘Free’ and ‘Capable of showing Traffic from PilotAware’, I can’t help thinking that there are much better ways to display traffic (apart from the well known ‘Paid For Nav Apps’), including the inbuilt PAW Radar or Aircrew.
Some users may, however, find the inevitable compromises outlined above don’t distract from what is a potentially useful ‘Free’ Navigation and Traffic App.
Thanks for bringing it to our attention.
Best Regards
Peter
