Working Hard
Again - another misapprehension.
LARS funding comes directly from IFR en-rte charges, NOT general taxation. So, it's being paid for by everyone who flies IFR and weighs more than 2000kg MTOW, whether they use the service or not.
And the amount of money units get for LARS doesn't even cover the cost of 1 ATCO (I know - I've just seen the letter from DAP that tells us how much we'll be getting!).
