You learn something new every day!
I asked about the night rating at my school and was kind of ignored!
Now I realise it was because they wanted me to do it after the PPL so they could generate more revenue!
(I haven't so they haven't, but if I had they might have by way of more rental income!)
I have done the IMC test and a renewal, but not a NQ. Frankly I'm not sure that I need to legally, but certainly my local airfield will only allow night flying by those who are on a special list.
