Now that's a nice idea. If FG crashes, restart from the last situation. That in turn would mean, you need aircraft which support this. Starting up with engines running at a certain speed, autopilot on certain settings etc. I don't believe (m)any aircraft have this right now.

Which reminds me, I wanted to start looking into this state-thing James was talking about last year...

It's quite a bit of work to do

It is a great feature! If only it is possible to add this to the "product backlog" I am waiting impatiently.

Sorry, I had missed the latest batch of messages. I've uploaded (before reading this) FFGo 1.12.5. The only change is a fix in the German translation. Since the problem was confusing, I didn't want to let it rot for ages before being released (thanks chris_blues).

Regarding the most recent discussion (restart at FG's last position): this needs FlightGear support. If people want this to work to resume from FG crashes, FG would probably need to record the aircraft position every 15 seconds or so (we don't want to slow down the sim just for this!)... which can be done with the generic protocol and stuff like that. I'm not sure this could be done in a more "economical" may (get the position only once, at exit or inside the crash handler). Erik probably knows.

Given such support, restoring --lat and --lon should not be a big problem, but you could easily find yourself in water or on very bumpy or slippery terrain -> probably not helpful at all in many cases. Restoring --altitude would work on some aircraft, but many can't be started in air...

So, while nice in principle, there are a few problems for implementing this.

Yes, that should be done FG-side. And there is something coming up in the near future, though it's more aircraft-side than FG-side: "state overlay". The Citation already has this. By adding
Code: Select all
--state=cruise --altitude=whatever --lat=coords --lon=coords
to your command line (or FFGo for that matter) you can start anywhere you want, in air, all systems up.

It'll take a while though, till more aircraft support this feature. But that pretty much comes very close. Now If there was some way to record the coords in flight, you'll be ready to go. (This might be a short Nasal script, which puts all needed data (altitude, lon, lat) into some file.)

For those using my Debian FFGo repository, I've updated the OpenPGP key to extend the expiration date (the previous expiration date was on October 24, 2017). The same procedure as last year should allow you to get the updated key and install it for apt.

By the way, if you have gpg configured for your account and my key with the old expiration date in your gpg keyring, then getting the new key is even simpler:
Code: Select all
gpg --refresh-keys
gpg --export 125B5A0FDB788FDD0EF41A9DC785B90B5053A3A2 >output_file_for_key

Then you can run the following as root:
Code: Select all
apt-key add output_file_for_key

and you should be done.

Note: this is to get apt happy when using my repositories (there is no new version).

BTW, are there any news on FFGo? Some new features? Something to translate? Haven't pulled since ages...

There are no news since version 1.12.5, sorry...

No problem! I see you're rather busy on the mailing-list... :)
