Version: 1.5.27.0
Frequency: Consistently
Severity: High
Context: Consistent behaviour throughout all aircraft.
Bug description: If a payload weight is set for a station through the EFB, the simvar for that for that station PAYLOAD STATION WEIGHT is updated. However, if the simvar is manually written to, the EFB does not update. As a side effect, any objects/cargo being shown via the EFB though this method: Aircraft Loads is also unaffected by the manual write to the simvar and will continue to display.
These are images from my recent update to the DHC-2 Beaver. The first image shows the sync between the EFB and the simvar when adjusting the cargo amount through the EFB:
The second image shows that the simvar has had a value of 0 written to it successfully. However, the EFB remains with the previous weight displayed, and the visible cargo is unaffected:
This is a major issue that affects the ability of many developers to tailor dynamic cargo simulations for their aircraft, not just us. It has been brought up numerous times on this forum by others without response. Being able to programmatically adjust the payload station weight while remaining in-sync with the EFB is essential for developing more detailed load managers, or to simply allow for dynamic transitions of cargo (moving, dropping, etc) while allowing users to manage weights via the sims EFB.
Potential use for developing and integrating new features aside, this is clearly a bug in and of itself.
Tagging onto this bug, and it’s request to be fixed, I’d also like to make a suggestion:
Right now, all payload stations are designed to be variably filled, allowing the user to change the weight so that they may be partially or fully filled. However, many cargo objects that an aircraft might visually be equipped with are ON/OFF: They are either present at 100% weight, or are not present at all. Using the Beaver in the images above as an example, a semi-famous cargo was a canoe being strapped to the float struts.
To that end, I’d suggest that the possibility be added for a payload station to be optionally flagged as ‘full fill only’, where the configured weight could be toggled on/off, instead of set via a slider or incremental adjustments.
