Thought I'd update those within this thread,
Following discussions and suggestions on Modular, I've now booked my ATPL Theory with a April 2020 start date with FTA at Shoreham.
Between now & then I will update & build hours required on my PPL along with securing a night rating on a PA28 I have access to at Andrewsfield.
CAE did eventually get back to me with start dates:
- Friday 24th of January 2020 – AP436
- Friday 20th of March 2020 – AP437
However as above, and after discussions with fellows on here & locally - Modular was selected.
Thanks to all those who stepped in to advise, I do believe the correct choice has been made.
