The usual FI 13B in a plane will go for about 3 to 4=20 hours.

Ian.

 
3 to 4 = hours?  I=20 think I'd have to see that to believe it.   =
 
Here are = some=20 measurements I took with a DC clamp meter. 
 

NOT=20 RUNNING:

 

Fuel = pump 1- 6.2=20 amps

Fuel = pump 2- 6.0=20 amps

Facet = transfer pump-=20 1.1 amps

Davies = Craig EWP-=20 4.4 amps

EC-2 = (also ignition=20 coils)- .3 amps

EM-2- = .6=20 amps

Master = switch only-=20 6.4 amps (what is all this?)

Radio = (receive=20 mode)- .7 amps

Transponder-  .5 amps

CD = player- .3=20 amps

 

RUNNING:

 

Minimum config=20 includes FP-1, EWP, EC-2, EM-2, and of course ignition coils.  Alt is turned off because the = master is=20 off.   12.1 amps at = 1500 rpm,=20 14.1 amps at 3000 rpm.   

 

I had the plane tied down, = and was=20 standing next to it, with the clamp meter on the battery cable in the = baggage=20 compartment behind the seat.  3000 rpm is about all I dared to = run. =20 If the current increase is linear with rpm increase, then I'd be pulling = 18.1=20 amps at 6000 with the EWP on.  Without it, 13.7 amps. =20

 

Max = load, as I=20 normally fly, includes everything. =20 Alternator is off though, because I couldn’t measure the = load at the main=20 battery lead with the alt supplying power- 22 amps at 1500 rpm. 

 

Estimate 28 amps at 6000. 

 
Cheers,
