E-Jet flaps level positions
Gentlemen,
Does anyone know the reason that Embraer E-Jet family aircrafts have flaps positions 4 and 5 with same flaps/slats deployment?
When on final, the usual flaps selection is Flaps 3 at GS intercept, next Flaps 5 before 1000' AGL. So, Flaps 4 position is always skipped.
When on Go Around with Flaps Full, then Flaps 4 will be selected, but it has same slat/flap deployment as in Flaps 5 lever position.
Why does E-Jet have this extra flaps lever position? Reserved for future generation?
