Hi AirNav Developmentteam,
1. In some labels appear the term "null". What does this mean?
2. Some news about the conversion of my old routedatabase?
Hi John,
null its mean is not information for that aircraft and you must find in websites like this: http://www.airframes.org/ that information and then in database explorer you change that null and put the correct data.
About point 2 i can' help you, :):)
Regards.
