I don't think it's close to that.

The sim is the major cost here. I don't know what the actual sim cost is, but lets just say its 1k/hour for grins.

I'm going to do some really backwoods math so bear with me here. I'll try to stay on the expensive side so we stay conservative.

Lets say 8 hours a year in the sim. 8k. We'll cut that in half since you'll have a partner in there with you. So there's 4k a year.

2, maybe 3 nights in a hotel at 150/night. 450/year.

Instructor for 8 hours divided by 2 for the partner again at 150/hour. 600/year.

Pilot hourly rate 100/hr for 8 hours. 800/year

perdiem at 2/hour for 8 hours. 16/year.

Grand Total. $5416/year.

Now that is at sim time being 1k per hour. I'd be willing to bet the actual cost for an airline to run the sim is less than that, especially if the own the sim themselves.

This is pure speculation of course and I could be not even close to the ballpark.
