For a PPL, if the alternator goes out and I'm running on battery power, the typical advice is turn off what you can to conserve power. But what exactly is safe/unsafe, or order in which to turn off equipment?
I fly a Piper Cherokee. So in that case, I'm thinking the order in which I can do things is as follows:
- Call out that I've had an alternator failure, either to traffic or ATC.
- Turn off lights
- Turn off avionics
- Turn off pitot heat (Technically where I fly, it's blazing hot and we never need pitot heat, but I'm listing it as number 4 as it's more of a flight functionality/safety issue)
- Fuel pump?
My concern is #5. Cherokee is a low wing and when we come into land, we always keep the fuel pump on. So I'm guessing it's never okay to turn off the fuel pump and just fly the plane. However much time I get with the fuel pump, I'll take.
Once all power is gone, then I can proceed with power-off landing procedures.
Is this the right way to think about it?
