What seems to be missing is why positive climb was ' called' perhaps prematurely. SLF here but generally familiar with energy issues. Even near landing speed, there is a LOT of interia available for what might be called a zoom climb- trading speed for altitude in short term. NO additional thrust required. However after perhaps a few hundered feet gain at low speed, without a major change in energy available ( thrust) or a major decrease in drag, the plane will then drop or stall.
Perhaps- just perhaps- a premature callout of positive rate or positive climb in this case was significant.
Would there be any advantage in say counting to three to five seconds AFTER observing on insruments a positive change in altitude BEFORE calling out Positive Rate or Positive Climb. ??
