Now I am curious on the terminology. Dagnabit.
I recall hearing/seeing something about why the FAA uses more and more contract towers. Here is what I recall:
1. Due to some aspect of an annual appropriations bill decades ago, the FAA was forced to somehow codify how airports are selected for staffing by direct FAA employees versus contractors. This effectively mean the FAA was put in a situation where if the tower is staffed by FAA direct employees, the FAA will never be able to shut it down the tower.
2. Some aspect of the national union contract negotiation, the FAA did not really consider small airports, so to staff a small, low volume airport with federal employees takes many more than contractors can do it.
3. The color of the money, FAA employees come out of one bucket, contractors out of another. And it is very difficult or impossible to move the money between buckets.
4. Perception is that contract towers are easier to open/close and move resources around to best match capacity vs budget.
However, due to politics and Congress, number 4 does not happen. Which means, #3 is not addressed. Which means there is no incentive by anyone to fix the first two.
Welcome to inertia.
Now my question is, what are the correct terms. And what, if anyone knows is the actual reality of why so many contract towers.
