IMHO the ONLYRELIABLEINDICATION
that should be looked at and followed
is an INCREASE in ALTITUDEON the ALTIMETER,
which confirms a ”POSITIVE CLIMB !”
So, forget the VSI (and all others…) and look at the ALTIMETER !
Totally agree. You watch the VSI at rotate. Disturbed static air. The VSI gives erroneous readings, albeit momentarily. . Watch the VSI when the gear doors open and close. If you saw that you wouldn't rely on a vsi again, for positive climb. Notice i stated positive CLIMB, not rate.
