Come ON!!!!!!!!
It was an MPT flight. You don't fly far enough to have to engage the ALT hold. All the ones I have done you're looking to see which is the right ship; hope that it has the main deck lit up as well as the helideck; and busk it from there.
I presume that it was a VLOC he was going for. They are not too bad and when you are going to a VLGC then you have the structure effects.
For those that don't know what a Very Large Gas Carrier is.
The helideck is at the stern at main deck level. Any sort of ships headwind will generate armfuls of turbulence when you arrive over the helipad plus all the associated turbulence from around the tanks. The last thing you want to do is ponce about with an autopilot.
