How many fuel pumps does a Diamond DA20 have? And since the fuel pump sends fuel to the engine, if you turn it off after the takeoff as the check list says, how will the fuel reach the engine?
There are 2 fuel pumps on the Diamond DA20. One is electric and is controlled by the pilot and one is mechanically driven by the engine and is constantly running while the engine is running.
After take off, you switch the electric one off and the mechanical one keeps supplying the engine with fuel.
