I run the snow removal team at a small regional airport. It's very stressful. I am constantly juggling resources against needs. Timing is everything. And I have to be 5 steps ahead of the schedule.

The trickiest part is making sure the runway is in good condition for inbound aircraft. (I always say that snow removal during a storm is like sex - it's about ceilings and friction.)

It's an incredible amount of effort and money often with very little revenue. I'll give you an example. It was forecast to maybe snow this morning (fortunately it is mostly rain). Forecasting is pretty reliable so 3 days ago I had already organized manpower: overtime callouts for for 2 operators (for a total of 4) with two more ready to platoon later in the day if it went on all day. Fatigue is a big factor.

During the snowfall we are constantly monitoring the runway condition. Accumulations, friction testing, taxiway priorities, windrow size and placement.

Equipment took 2 days to wash and grease from the previous snowfall. Repairs took 1 day. Took deliveries of urea and potassium acetate. 13k and 12k respectively. (I can run through this in a about week or 2 months depending on conditions. Made sure we had diesel. Brine for groundside areas.
Spent a thousand dollars on runway edge light repairs. There are dozens of other smaller details to attend to as well. Things like making sure the Terminal buckets have salt for sidewalks. , helipad s are cleared, windows and snow piles aren't too high. Approach lights aren't covered. NOTAM's to issue. Fuel for generators for emergency lighting.

So, not including capital costs a two day snow event can cost around 20k for revenue of about 3k. Double that if aircraft fuel with us.

It's a crap ton of work. I love it, though.
