Eh? Did I say low g somewhere?
Anyway before someone beats me to it NO this phenomenon is not induced by a ham fisted 65 year old trying to learn to fly.
Instances of chugging have generally occurred on aircraft operating with high forward C of G conditions (large pax/low fuel), with the phenomenon usually encountered during a descending turn, however it can also be in evidence in other flight modes, such as straight & level at high speed. Aggressive manoeuvres may also initiate the onset of chugging.
I hear you saying “what is this guy on about” but believe me this is real folks.
No I have not given Frank a collect call yet. I have been told they are aware of this phlemanemenom though.
