It's old, but not hard. People get wrapped around the pneumatic panel for example and I've never understood why. They drew the schematic on the panel, so if you know your systems (like pilots used to know them when this thing was designed) it should be a nonevent. You have to manually select generators instead of them just coming online automatically, use the 6 pack instead of EICAS, etc...... Those are some first world problems. Once you look past that, it pays well and provides a good schedule.

The APU isn't always the magic cure since some of them are weak. I write them up and maintenance says that they are within limits. One stupid limitation is that you can't run a pack if ground air is hooked up and the ground crews take their sweet time unhooking air when you call. I've started calling operations and telling them to hold off boarding until the air gets disconnected so that we can cool the cabin. That usually gets them moving.
