After my PPL flight test, my examiner told me that I could log it as P1 because I had passed....he didn't mention Picus
It is PICUS and entetered in the PIC column and counts as PIC time.
that time learning on a different ac, is it P1 or Picus?
You mean a checkout? Neither, They should be logged as PUT because to me, that is being under instruction for a new type within a class. Bizzarely you could count checkouts as P1 if the pilot checking you out is not an instructor! It does beg the question that you could log P1 if they were an instructor and they declined to log P1 themselves.
Linda,
If you then convert it to a pass on your second (or third etc) attempt, you can count this time as P1.
I'm not sure I follow what you mean by "or third etc". If you didn't pass within two attempts then you've failed. Do you mean that if you pass within Series 1 you can count the Skills Test (all required flights within the two attempts) as P1 or just the last flight?
