Carb icing conditions

BTW, I don’t believe this depiction of carb ice to be accurate. If the ice accumulation was so severe as to block the inlet tract and cover the throttle plate as shown, the throttle plate/shaft would stick in position or wouldn’t fully close – which does not seem to be the case. It also wouldn’t melt and clear immediately when carb heat is applied as is often the case.

if I can find an old TT/PPL “manuel de vol” I’ll see what it says and post it if I can.

If it can help, I have the excellent Zilio book here, I can scan a page and post it here if you wish.

@etn thanks for the offer but I was actually looking to see how much the French PPL training terminology for carb/throttle heat has changed since the 1990s to the current PPL a described in greg_mp’s post.

In this week’s FFAREX a report on a DR400/180 suffering carb icing in cruise.
Strong humidity and temperature around 10°C. It occurred in the Macon area on a flight from Lyon Bron to St Cyr.
