Brief description of the issue:

Widely reported by many forum users: The LE flaps do not deploy when the manual states that they should. They never deploy in all the testing I’ve done.
The indicator lights in the cockpit turn blue when the trailing edge flaps are completely retracted, and turn off when and the flaps are deployed. It seems that the indicator light should show as blue when the LE flaps do deploy? Since the LE flaps are not deploying at all, I can’t tell what the correct indicator behavior is supposed to be.

The LE flaps are deployed with the Pan Am livery if you load in as an Arrival at any airport. To do this, just click on an airport on the world map and click “Set as Arrival” and then click “Fly”.

The LE flaps are never able to be retracted in this situation, even if the flaps are completely up and then accelerating to extremely high speed.

yes

Provide extra information to complete the original description of the issue:

Blue lights: wrong code in folder ModelBehaviorDefs, file B707_front.xml, NODE_IDs warn_flapfail_left and warn_flapfail_right.
Extend and retract: missing code to animate, although Simvars LEADING EDGE FLAPS LEFT PERCENT and LEADING EDGE FLAPS RIGHT PERCENT can be written to succesfully.
See mod: “https://flightsim.to/file/83079/msfs-boeing-707-320c-leading-edge-flaps-animation”.
