I got my PPL in Feb and joined a club in EIDW. I just got back flying there about 2 weeks ago and have just over 3 hours in. Im expecting it to take between 5-8hrs as i have to get used to EIDW's procedures and also I have flown solely cessna's up till now and the club fly PA28's.
If you brush up on your maneuvers(slow flight,stalls etc) and get familiar with Irish R/T it will help speed things along!
Cheers
Ian
