The usual FI 13B in a plane will go for about 3 to 4 = 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=20 pump- 1.1 amps

Davies Craig EWP-=20 4.4 amps

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

EM-2- .6=20 amps

Master switch=20 only- 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=20 is off. 12.1 amps = at 1500=20 rpm, 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=92t measure the load = at the=20 main battery lead with the alt supplying power- 22 amps at 1500 = rpm.

Estimate 28 amps at 6000.
