And with the AS350B3e and EC130T2 the FADEC controls all. If you try to select ground idle in flight with the collective still 'up' it wont let you, it carries on (after a short blip) in flight mode. You then can not re-select ground idle, you have to shut the engine down in flight idle to reset it. You can only go to idle with the collective (almost) down first.

FADEC...e for engine, or electronic?
e. Electronic Engine Control (EEC) System. The EEC system is the generic family of electrical/electronic engine control systems, including full authority digital engine controls, supervisory controls, and derivatives of these.
j. Full Authority Digital Engine Control (FADEC). FADEC is a control system in which the primary functions are provided electronically and the electronic unit has full-range authority over the engine power or thrust. FADEC systems have been certificated that employ either two identical channels to provide full-operational capability after failure of one channel or a single channel with a simplified electronic or hydromechanical back-up to provide an alternate operating mode.

this is complete rubbish 
I have practiced Autos in the 350B3, B3+, H125 & H130T2 & I know that when You close the throttle at MCP or even higher power setting the engine immediately throttles down to ground idle, this is at any speed, height or lever position. Returning immediately to flight idle the moment the throttle is reopened 
Auto's could NOT be practiced if this were not the case

I think MAFF was referring to what happens AFTER you have had a dual channel failure and when the EBCAU is operating.
I don't think you would continue to practise auto's once you've got both RED and AMBER GOV lights ON...
Ref Ch 3 & 7
Major GOV failure:
''collective pitch- avoid abrupt changes'' ''maintain Ng over 80% below 20000ft, 85% above ''make a powered approach'' ''avoid steep angle'' and once on the ground, ''collective down slowly'' ''Engine selector -OFF'' Engine MUST be shut down from FLIGHT, as the twist grip will not work.
The EBCAU will maintain Nf between 388 and 400 rpm
Happy New year!

Not beyond the realms of possibility of it not working on a 3B despite no actual occurrences to date.
