Quite a sporting approach, ended up with about -8 ( back to VLS ) to +15 at about 100' down to 50'. Kept under control and guess what:--
I used THRUST to manage the IAS. Only after giving it a big boot full for a few seconds did the IAS return to VAPP at 80'.
Quite a few contradictions there I would say. Maybe you want to review the values?
I thought you were at +15 from 100' to 50', why did you increase thrust?
