The C152 has quite similar permissible flight load factors, but on the other hand - it's the same weight as DA20 and slower for about one third.
Well, anyhow, discussion about VLA weight will most likely be redundant, since the proposal is to lift the MTOM for aircraft certified according to CS-VLA to 890 kg and at least one problem of the standard will likely become history.
I just tried to look at EASA NPAs for that. I can't see that, but interestingly did find a 2004 EASA NPA for CS.VLA proposing night clearances.
Can you give a reference or link for the 890kg NPA, and has anybody any idea what happened to the night certification proposal?
