Hi there,
This is what I did in 2019.
Type rating lapsed by 4 years (3+>Y)
Type Rating on G-V expired (lapsed 2015). 500+H on type
Type Rating on GVI current. 500+H on type
Total Time 8000+H
The UK ATO decided that a standard G-V type rating recurrent training course (2d ground school, 3 sim sessions (6H)) was sufficient for the G-V renewal.
It should be mentioned that the G-V recurrent training course was preceded by a standard GVI recurrent training course.
Hope this is helpful.
