Is this not the time when we ask to see WUR control pressures measured from cold to warm over a duration of 4-5 minutes? The engine does not need to run in order to do this
Or did I miss them.
Also how is the screen on top of the WUR looking? See the photo attached. This mesh can get clogged. If you start at cold with Low bar the CSV injects extra fuel and the WUR leaves more fuel through, after the WUR heats up it reduces the amount of fuel and if that screen is clogged it could just as well be reaching a point of not enough fuel anymore.
