I flew with ex Transair (Irish) A300 FOs who had been panel operators without FE license. Also I think the Dutch did the same.
The 2 day course was Read all the questions and answers, about 1200, then take the exam. I then did the Electra course with Zantop at Willow Run.
7 years on the Electra and 15 on the A300-B4. Now out of work.
