I see - sorry makes sense now.
Having attended both open days and the assessment, it isn't until the presentation at the start of the assessment day that this information is provided.
I jotted the figures down on scrap paper but can't seem to find them now but the figures were something like: $2800 p/m (+ flight allowances) whilst acting as second officer then $6500 p/m (+flight allowance) once FO. Obviously this is a ball park figure on their part.
When asked how long you would act as S/O they couldn't be specific but said approx 6 months.
Now if paying back the loan at say £1k per month, this may make the first 6 months a bit tight.
Good luck with your assessment.
