Autopush: Automated pushback

Postby merspieler » Thu Aug 09, 2018 10:29 pm

What is autopush?

Autopush aims to develop a generic pushback for JSBSim and YASim
aircraft, with the following characteristics.

1. Do the pushback procedure automatically.
2. Scale to different aircraft with minimum changes to their logic.
3. Use no computer resources in flight.


So what does autopush change for the user?

First of all, the pushback doesn't disappear when the dialog is closed:

The dialog it self has changed a bit as well:
Image

The upper part can be used like the old pushback: Click connect and use the speed to push (or pull) you.

The lower part belongs to the autopush system.

By clicking `Enter` you can plan your pushback route in advance (if you are not in a outside view, the view will go outside):

Image

When you're done with entering your points, klick `Done`.

To review your route, tick `Show`.

Klick `Start` to start the automatic pushback. `Stop` will abort the pushback procedure.

The dialog can be closed at any time without influencing the system.

This system gives you the possibility to do your engine start procedures while pushback.


You are a user and want to try autopush?
Here is a list with all aircrafts we know of having autopush. (Latest version we're aware of)

If you want your favorite plane to have autopush open an issue or write the maintainer on the forum and link him/her here.


You are a developer and want to add autopush to your aircraft?
You can find the instructions on how to add autopush in the README.


No matter if you are a developer or a user, no matter if you have a bug or a feature requests please go here.

For general feedback, please write a reply to this post.

Thanks a lot for this great feature! I 've implemented an earlier version some time ago locally on the 777 and it's really fun!

wait... what?

someone is going to start their engines while they are being pushed back? that sounds hideously dangerous... especially if there is external equipment hooked up to facilitate engine startup...

"Why not?" said Gurder.

Well, in real life (the huge room where the ceiling is sometimes blue and sometimes black with many small lights) they do that. Just watch the pilots eye videos ;-)

wow... just wow... i would have thought that they already had their engines started and idling before requesting push back... maybe they do it with some craft for other safety purposes?

generally speaking, i don't have time to watch many videos and i don't know which ones you might have watched to see something like this... however, if someone were to link a video, i might watch it if there was some explanation for the link ;)

It depends as well on the airport... eg. i've seen charts where you are not allowed to start engines on the gate but you have to be pushed back first.

interesting... i assume they push back to a safe position before starting up... alright... cool... it just seemed strange... keep up the good work ;)

Exactly.... Ground crew sometimes give ground clearance for this purpose.
