Bug #6957
Airbrakes always load in retracted state
100%
Description
As subject says, whatever you do with the Airbrake (A.I.R.B.R.A.K.E.S) it is always loaded in retracted position.
Reproduction steps:
- Go to VAB, start with a command pod, attach airbrake to it.
- Right-click the airbrake and click on State button so it turns to Deployed
- Save the ship
- Load the ship
Airbrake is retracted
- Right-click the airbrake and click on State button so it turns to Deployed again
- Deploy the ship on launchpad
Airbrake is retracted
- Right-click the airbrake on launchpad and click on State button so it turns to Deployed again
- Quicksave
- Quickload
Airbrake is retracted
- Activate brakes by pressing and holding the B button or by clicking on the brake button next to altimeter
- Quicksave while Brakes indicator is still active
- Quickload
Airbrake is retracted and does not even deploy although the Brakes indicator is still active
- Right-click the airbrake on launchpad and click on State button so it turns to Deployed again
- Return to Space Center
- click on ship on Launchpad, select Fly
Airbrake is retracted

In 1.2, airbrakes deployed while quicksaving load undeployed and start deploying. In result they are deployed, but they don't apply full braking while deploying, resulting in different behavior than in non-quickloaded run.
Tested on quicksaving a ship with deployed airbrakes in freefall at terminal velocity - the fall was at constant speed when quicksaving, but the ship started gaining speed after quickload, then losing speed again after they fully deployed.
I don't consider that fully fixed.
Attaching quicksave with test ship deployed on launchpad. Reproduction steps:
- SAS on, launch
- wait for end of burn, then wait for top reached altitude
- deploy airbrakes
- wait till ship falls to 1000 m, then quicksave; note falling speed
- quickload, note the speed starts increasing while airbrakes are deploying

I just retested the issue with KSP 1.2.1 and I'd like point out that the issue was closed without being fixed.
Airbrakes still load in retracted state.
The fact that they start deploying after the ship was already moved to physics is not a fix. Apart of change in braking characteristics during deploying (which may cause problems on its own, depending on situation in which the save was made), there's no rule that Airbrakes cannot be used as makeshift landing legs, potentially crashing the ship after it's loaded.
