The Expanded Nav Log problem you describe doesn't happen here. Did you buy v5.0 at the PFA Rally? If so, there is a fix already available (was within a week of the Rally) at
Navbox.nl (Select 'Free Downloads'). According to the site, this was because v5.0 didn't display airspace labels, and brings the version number to v5.01, which is the same as the CD sent out to database update subscribers.
The 'Exit' becoming 'alt' characteristic you describe does occur after selecting Expanded Nav Log with v5.01. However, the 'Exit' functionality is still there - it's just a mis-labelling. Quirky, but hardly a major "disappointment" IMV.
As WCollins says, the terrain and obstruction info is a major improvement. APart from that, the following is from the "What's New" file that comes with it:
NavBox ProPlan News in version 5, compared to ProPlan 4:
- New waypoint types:
Runways - with final approach fixes
Air sport sites - parachute drop zones, hang gliding etc.
Obstacles - with altitudes and heights.
Cables - with altitudes and heights.
High natural spots - with altitudes.
- Terrain database:
Contains about 33,000,000 square kilometers with elevations
to cover all of Europe. Elevations can be made visible on
the ProPlan maps by selecting terrain colors.
- Automatic MSA calculation in the expanded navigation log:
Minimum safe (terrain and obstacle clearance) altitude.
The user enters a proximity distance and an altitude to
add to the heighest elevation found.
ProPlan will then calculate the MSA, taking into account
the terrain database, published airfields, beacons,
obstacles and cables.
- Import/export route (club flights):
The user is now able to save the current route to disk in
file 'OurRoute.nbr'. The file can then be distributed to
other NavBox ProPlan or QuickPlan version 5 users.
This file assumes that all route waypoints are available
in the database of the receiver, otherwise the receiver
will get a warning that the waypoint will be skipped.
Notes:
- QuickPlan 5 does not support the ProPlan IFR database
(airways, intersections and runways).
- Temporay waypoints will be accepted.
- User waypoints will not be accepted, unless the receiver
has the same ID and position in memory.
- Better airspace drawing.
I still think it's an excellent product, and if a suggestion I've had from Navbox themselves bears fruit, it's about to become a lot better still sometime in the Autumn.
I'll leave it to Navbox themselves to tell you what, if they find their way to PPRuNe and choose to do so. (I'm just a happy customer).
