Turbo - No Fuel Flow

Woolies

Ok. Yes. Just tested again. No fuel flow showing during prime but tablet showing flow to engine and I managed to get the aircraft started.

However the FF gauge doesn’t come alive until I go above about 1600-1700 rpm, until then it is in resting place below zero.

MSFS2024 btw

Another thing I noticed, on both variants, is looking at the tablet engine display the R Mag greys out when staring the engine and then goes orange again when started?

@Ratman I'll check on this later. The code is identical between the two airplanes, so I'm not sure what could be going on. Rest assured, I'll find it, though.

@Woolies This is the correct behavior. Only one magneto is equipped with an impulse coupling, which retards the spark timing for start.

Cool. Many thanks for the prompt responses

I tried to call the number but got no response ??

I think if you keep priming you'll notice the FF start to register in the turbo. I find I need more like 5-6 seconds of prime rather than 2-3. Starts great every time after that for me.

@Woolies @Ratman Hi guys. I couldn't reproduce this today. I saw the exact same fuel flow on the underlying variable, and the fuel flow gauge read exactly the same. What was the ambient temperature where you were flying? Was it colder than ~60°F/15°C? Did you tap on the glass to see if the needle was just a little sticky?

Ratman

The first few times I tested it, I was at KSEZ where the outside temperature was around 40°C. I've now tried it at another airport where it's about 19°C.
The fuel flow still didn't increase at first, but after giving the gauge a couple of light taps, it came to life. So everything is actually working exactly as it should.
It turns out the mistake was mine—I just forgot about the little details you build into your aircraft.

I have one more question, and it may very well be user error on my part.
Is the TEST button on the TKM MX-170B radio currently functional? According to the manual, it should open the receiver's automatic squelch, but when I press it while tuned to an airport frequency and listening through the pilot's headset, I don't hear anything.
Am I missing something, or is this function not implemented yet?
