Unable to lower the landing gear after the engine is turned off

[Sunny0408]

I don't know why, the landing gear won't lock after the engine is off

Landing gear is hydraulic, hydraulic pump is powered by the AC gen on the engine. I don’t believe the emergency release is modelled so if your engines are off, and therefore AC gens are offline and you have insufficient hydraulic pressure left to actuate the uplocks, the gear is going to get stuck up.
