Can someone be so kind as to explain briefly the working principle behind spring tabs?
Also, would I be correct in saying that we have
External/Control Balance Tabs
- basic elevator tabs (controlled by a wheel/flick switch),
- Balance/Anti Balance tabs (not moved by pilot ... move with control surface)
- servo tabs
- spring tabs
Internal Balance Tabs
- control horns
- insert hinges
The above being all that is necessary for the ATPL (POF) ... this shouldn't be a difficult topic but it's something I'm slower to get to grips with than others. I have used the BGS ATP extensively but unfortunately some things are still not clear for me. Any help is appreciated
