@Eric-Katzfey gazebo evidently is not publishing diff_pressure but I am confused as to why. from what I have seen online, usually it just works out of the box for people when they build the world. i even checked all the .sdf models in the gazebo classic repo and all the mavlink plugins for fixed wing and for quads are identical. where would this be configured ?
all I see in gazebo is the airspeed topic like such:
gz topic -d 4 -e /gazebo/standard_vtol_hitl_world/standard_vtol_hitl/airspeed/link/airspeed

and but when it comes to the received mavlink messages:
this is the closest I have to diff_pressure
