Epr<> Drag ??
Just wondering the other day during a descent,...
Why would the EPR indication during an idle descent is during most of the time, lower than 1.0 ?
Isnīt this a sign of incoming Pt greater than outcoming Pt ? ( whatever the stages ). That is... more presure incoming than outcoming ? thus , our engine "blocking " instead of at least letting flow-by the airmass ?
Even more worrying...
This happens during most of the CRUISE phase too !!!
What piece of info am I missing here ?
( canīt sleep... )
Thx.
