I posted a question regarding activation of alternate air doors/flaps for the
induction system. Question basically was does anyone know at what negative
pressure/inches of H2O/inches of hg should be considered 'time to
activate'. Engine is turbo charged. I have had scat (or sceet?? no
inner liner) duct collapse during take-off on the T210 I used to
have when the inner coils had gotten displaced somewhat, but I
don't know what negative pressure would be considered 'normal'. I am
thinking of installing a vacuum operated switch to possibly electrically
operate a door. Or, if a magnet door is used, how strong a magnet would be
required.
Would appreciate
any suggestions.
