    Just confirming I have got this right; there was a 1500 ft vertical error in the GPS position sent from the Skyecho ? This appears to be nothing to do with potential errors between baro and GPS attitude and everything to do with poor satellite spread or number of received satellites and either; 1. the high potential error calculated not being passed to the moving map software or 2. the moving map software ignoring the potential error and displaying position without a warning. (apparently Skydemon does display an potential error but not promenently). The UAvionix response in the video is misleading to say the least .

    Not saying 'electrically dependant' is not an issue to be remediated but is it actually a bigger risk than carbs/magnetos ? The 912IS requires battery power to start but not to run. The IS has two alternators with the first being 10?amps for engine (ecu/fuel pumps/spark). If this fails the ecu can switch everything automatically to the second 30?amp alternator (normally used for avionics/battery charging only). If the second alternator fails then the engine will stop. Reconnecting the start power will allow you to restart the engine but it is recommended to reduce the avionics load and land with 30 minutes. This seems like a pretty fair level of redundancy to me. You can also fit a third external 30amp alternator but this can only be used for avionics/main battery charging.

    The Rotax 912ULS and 912IS of similar vintages are pretty similar in climb and cruise preformance. The IS is more fuel efficient in cruise. Is the 914 still an option ? Look at the 915 for a fair bit more in cost. The power requirement/backup issues of the IS seem well known and allowed for and the 912IS has been flying for 12 years. The both versions of the 912 seem ideally suited for either 600 or 760kg. Are you really looking at high attitudes ? A lot of these aircraft have limits of 13,000ft (ish) The Sling 2 is both an LSA at 600kg and a VLA at 700kg and was flown around the world in 2009 at 900kg each day for 40 days. It used a 912ULS. With this aircraft going to class G this will now (soon?) allow you to take 2 people with full tanks. If you want to fly both engines then Fly Illawarra have an Evektor Sportstar with a 912ULS and a Evektor Harmony with a 912IS.

    With Group G looking to have similar maint requirements to GA perhaps group G owners will stay with Casa if they can self assess (and some VLAs ie Sling 2 may go back). Interesting timing on these 3 (PPL self assess, RAA group 4 and RPC controlled endorsement). I guess as long as more people can fly more places with more fuel its all good (if/when it actually happens).

    Possibly VFR up to 10,000 only with Class 5 PPL (guessing from no night VFR) and controlled endorsement with RPC at about the same time to reduce arguments. Anybody have any more info. If CASA don’t stuff it up and make it too restrictive would this make RAA less attractive ?
