Yep... if you are flying in an unpressurized aircraft for 30 minutes or more at or above 12,500 MSL, oxygen is required for all crew members. If at or above 14,000 MSL, oxygen must be provided for all passengers. You can boost the landing light power in Plane-Maker, as well as adjust the pitch and width of the beam. I don't remember the steps, but it is really quite simple. My understanding of the fuel pump is that it is used at startup and, as you noted, when the fuel pressure drops below the green arc. There is a noticeable jump in fuel pressure when the switch is activated so I assume it is modeled. I have several planes that draw from one tank at a time. As Lukasz says, you need to manage the balance shifts with trim and fuel management. I have to admit I generally run on one tank until it is almost dry, then switch. Not a very efficient method of flying. As for the painting, it's going to rain this weekend anyway.........
