That is the late payement fee, it was cheaper if you applied earlier , not much though !
The fee allows you to Land at the service area and various suggested landing sites around the routes, there is no limit on number, you also get identification numbers for the heli and have to attend the briefing tommorow.
Still expensive if you ask me!
And they will probably find out why the 109 is a great corporate machine , but rubbish at landing in wet, stump and bush infested forests !
