Having flown in various Airbii (pax) and never having noticed the barking, and never having heard of a PTU, I had a bit of a Google and came across this site/
| Ozten Network Home | Aviation site
Two things- It informed me that a PTU does not actually transfer hydraulic fluid, so can anyone enlighten me as to how it works (in layman speak)
The other thing is that while the site is in, I believe, Turkish, all the articles / info sheets are in English. If I study hard and find a kindered soul who will let me have a go in an A320 simulator, will I be able to fly the thing?
