I am getting a lot of questions so forgive the FAQ!
Can I use SD anyway – even if I have PFMS.
SD does not have to run on the EFIS – Ideally you would export all the nav data onto the EFIS using one of the standard transfer file formats then you just transfer any updates and the plan for the day. If you want to use SD instead of PFMS for the planing bit the chances are that one of the output planing formats will allow you to get the plan into the EFIS – but you will be using PFMS navdata. You will also be paying two sets of subscriptions for two very similar products.
How do you get updates and plans into the EFIS
SD card or USB are the most common.
Airfield info
On PFMS you can export your navdata into the EFIS – this contains full airfield info for most places you are likely to want including most strips. I have a full set of data for all of Europe loaded. PFMS is updated daily, the export is free provided you have an up to date subscription.
Time to install the HW
This is very hard to predict. It depends on the existing aircraft systems and the panel. My guess is that the average reasonably competent LAA type could do the work in around 50 hours as an upgrade from a steam setup.
Ongoing work
Very little – once it is all set up it requires no tinkering other than putting updates onto the SD card. I keep two cards and rotate them so I have one at home and one in the aircraft. If you change the kit in the aircraft then you need to make changes – the last one I did was fitting a Mode S transponder – I connected the encoder from the EFIS and also an RS232 cable for ADSB out – with the com port set to off till I am allowed to transmit ADSB out. The setup etc is reasonably intuitive and there are owner forums and factory support if required.
Is there still room for improvement
Yes – my system is not touch screen and the level of integration and the connections are getting less complex. I have not flown with a touch screen system but I suspect the result would be more tablet like. The sensors and the “networking” is also improving but this has very little impact once your system is working. Radios and Transponders are also becoming more connectible, often via RS232 and the range of servos which can be connected directly, as opposed to via an autopilot, is increasing, again connected by RS232.
Are there many integrated solutions in use in LAA aircraft.
Most high speed LAA touring aircraft have uncertified EFIS solutions with high levels of integration. This will become even more popular when new rules on IFR come in next year.
And lastly – no I do not do this for a living, but I may set up Bodgit and Scraper LAA owner assistance when I retire.
I am involved a bit on projects to increase integration and effectiveness in the Aerospace world.
