Um,
I am not trying to sprook my spreadsheet, but was thinking:
(yeah, I'm an old fart. I think, rather than act, in a lot of cases.)
All these programs rely on internet connections, subscriptions, and other "ONGOING COSTS".
This program is a FLIGHT PLANNER and NOTHING ELSE!
Granted, the waypoints may be out of date - it still has SLS in its database, but so what......
Also: Granted it may not have new ones. Not the end of the world. It allows you to add your own/new ones.
It does NOT promise to be perfect. It simply removes/reduces the repetitive tasks where mistakes are sure to happen.
Totally shirking the flight planing stage to a program is only asking for trouble.
True story:
I have been to Tumut a few times.
I have a GPS, and a flight plan.
The GPS has all the waypoints and was programmed by me. (Yeah.....)
The flight plan was a re-make of last year's with updated weather.
I took off and was flying the GPS.
I was still learning how to use it, so I wasn't going to start playing with it while flying.
First leg YWOL - SLS/YGLB via a lake which is between WOL and SLS. That is SW. The GPS was saying head NW.
It wasn't s short distance either.
After a few checks, I decided to "chuck" the GPS, and skip that waypoint and go for SLS/YGLB.
Looked at the flight plan and turned to the heading written on the flight plan.
What happened?
Well, when I entered the lat/long of the waypoint, I goofed with one of the numbers.
It happens.
But because I had a written down flight plan, I had a better option.
CHECK YOUR FLIGHT PLAN!
I have another story, but......
That's a different story.
