"Crikey mate, when I was in 6th form I could barely afford the bus fair to the local aerodrome to look at the aircraft. What exactly does the modern 6th former do to earn three-four hundred quid a month?"
Lets say 2 hours.
G-AVLB:
£85 per hour.
£45 per month.
Therefore £215 per month.
Job: 4 hours evening per week x2 and 8 hours Saturday work @ £5.07-£5.75 per hour depending on department (let's say £5.07)
That makes £81.12 per week. Times that by four and you get £324.48 per month. That allows contingency for the flying to get study materials and other things.
