Commentary on Sections Part 9: Aviation Security Section 83 Trespass on aerodrome: penalty
178.The penalty for the above offence has been increased from a level 1 fine (currently £200) to a level 3 fine (currently £1,000). This reflects the view that the offence is not as serious as unauthorised access in a Restricted Zone or on an aircraft (level 5 fine, currently £5,000), but is proportionate to penalties existing under Article 122 of the current Air Navigation Order 2000 (S.I 2000/No.1562). Currently these involve fines in the level 3 and level 4 scale. At the present time a fine under level 4 involves a maximum sum of £2,500.
