Lt Av mag April
This month's Light Aviation mag hit the spot for me.
Particularly with the description of the new Weslake diesel. The Gemini design seemed to hold such promise yet disappeared without trace ... but now reborn in the latest Weslake design.
I have some reservations about use of common rail injection and an ECU, since this means loss of electrics means loss of the motor. However it looks like the supercharger is driven by toothed belt so loss of that belt would also stop the motor. I guess owners of this splendid new motor will be very drive belt sensitive.
Fascinating also for me was the profile of Tracey Curtis-Taylor in 'Meet the Members'. Have never met Tracey but her determination and personality come over loud and clear in the profile. She reminds me so much of the first woman pilots in British Airways that I was privileged to fly with. An amazing bunch of characters.
Thanks very much Brian.

Re: Lt Av mag April
Hi Mike, delighted that you enjoyed the Weslake article. Only the alternator is driven by the belt, the supercharger is gear driven. The electrical failure/ECU issue is one that confronts any of the 'modern' engine manufacturers, petrol or diesel, that wish to make best use of what in the auto world are actually quite old hat technologies these days. As a matter of interest I did discuss the possibility of failure of the potentiometer 'throttle' and in such a case the ECU can have a default power setting built in. I believe ECU current drain is also very low so a no charge situation would not be an immediate problem as a typical aircraft battery would cope for some time. I'll ask them about ECU failure to see what they have to say; I do know it is a very simple system compared to a typical auto application.
Rgds, Brian

I'll second the praise for the LAA monthly publication. It is without doubt the best GA magazine available at the moment.

The April copy never arrived through my door.
Is there an electronic version available?

There isn't Jon, but if you call the office, you can get Penny to post you a replacement. Mine was late, but arrived just as Penny was about to send a replacement.
