So, never seen this behavior before. KLAX to KMIA.
Started up, taxied from gate (which seems to work better now), took off, climbed up to 41K w/o issue. AP is rolling through Texas somewhere, and then out of nowhere I enter a STEEP (70-80%) bank to the right, and just start turning in circles, eventually slowing down enough to where I just start to fall from the sky.
Anyone else experience this, ever? If so, any way to ‘fix’ this?
