Approach,
Isn't it called cost benefit analysis?
To return to the Gove Tower situation. The cost was enormous to cover a Ba146 and a B737 (sometimes 2) well spaced movements per day for 5 days per week.
And that was 1985.
The only incident I know of involving a medium jet at Gove was the DC9 diverting to Groote Eylandt after one too many VOR approaches.
CAA (remember them) policy at the time was medium jets needed CTA.
In the age of user pays cost shifting, the economics are rarely there for the establishment and continued operation of a Tower and the associated airspace steps.
The same could be applied to the provision of RFSS, given that a B737 or A320 requires CAT6 fire suppression capability for a limited number of movements per day.
Isn't the lack of a Tower part of the reason for establishing a flying school at a regional airport?
Are we crazy? - Maybe!
