Multi engine fuel system & Pitot system

How much fuel can the Seminole hold

Can hold 55 gallons, 54 useable in each tank = 108 usable 110 stored

Fuel system from bottom to top

Left and right fuel tank connected to fuel selector in the middle, up to sump, up to heater pump and heater, up to electric fuel pump, up to primer, left and right to engine driven fuel pump on the side, up and back to the carb, cylinders 1,2,3,4 surrounding carb, primer attached to only cylinders 1,2,4

Why does the primer only prime cylinders 1,2 and 4

Cylinder 3 is for manifold pressure

What happens if ram and drain hole are blocked on the pitot mast

Airspeed will act as a non calibrated altimeter

What happens if the static port is blocked

Airspeed moves opposite of altitude, altimeter freezes, and VSI will bleed to zero

What happens when we pull the alternate air

Airspeed and altimeter will read high, VSI will show momentary climb

What is the FPM equation

FPM = (ground speed/60) X FPNM
