To be honest I cannot remember that I've ever seen the thing to a paralell entry...
They normally don't, simply because it is normally not programmed into the specific unit.
A parallel entry places the airplane on the non-holding side of the fix, so...in order to make all normal holding entries the same, the tear-drop procedure is used.
Many (all) stand alone GPS navigators used on business jets do the same.
Now lets see...in talking to many TRACON and ARTCC controllers (and supervisors) I have
never ever had any of them complain about a tear-drop holding entry procedure.
So, if they're happy, I'm happy....pedantic Eurolanders and malcontent Terps conference attendees, notwithstanding.
