Hoskins Fuel Flow

[mcpilot]

Is this on the M20J type certificate?  Was just wondering if it can be removed with the installation of a JPI EDM 830....

 

Alos, I believe they are no longer in production, correct?

I believe you can find the type certificate with an Internet search, or search the FAA site itself, or the mooney website.

Ideas off the top of my head...

I had a problem retaining fuel flow memory from flight to flight with my Hoskins fuel flow on my '91 TLS Bravo.  My avionics guy spent a couple of weeks trying to get support and finally gave up.  At the same time, I was installing a GTN 750.  The only supported way to connect fuel flow was through my JPI EDM 700.  Since the flow transducers were Hoskins tied into the FT101A, he came up with option to tie the Hoskins to the JPI then into the 750.  In future, I hope to eliminate the Hoskins.

 

I did finally figure out the memory problem with the Hoskins which turned out to be a problem with the factory installed digital chronometer not working.  I noticed in the wiring diagram and maintenance manual that the clock could be the problem if Hoskins doesn't keep its memory.  Unfortunately, mid-continent no longer produced or supported this chronometer, so I purchased a working used one off ebay.  A working chronometer solved my problem...

Bill,

what year is your M20M?

Wondering if I have the same Chronometer. I have everything else you listed...

The Hoskins fuel flow is not a required instrument and may be removed completely or display only. When the MSC installed  the JPI EDM 700 in my M20J they used the existing trasnsducer to supply signal to the 700 and disconnected the Hoskins unit.

Thanks very much Cruiser for the info!
