thanks... so.. (trying to understand)
If a bit of airspace IS notified for Schedule 8 ANO then a normal PPL can fly in it provided visibility > 3km. IE White Waltham flying area in London Class A CTR
If a bit of airspace IS NOT notified, then a PPL may not fly in it but an IMC rated PPL pilot may fly under IFR in it, but only if it is Class D ?
Are the above correct ?
Sorry to appear so slow !
