What are the temporary positions with air methods? Guessing covering for pilots on deployment or out for medical issues so duration varies by need? Will AM hire for a short duration or do they expect you to be employed long term and move to a different location when the pilot returns? Any other info on these positions? 

You will be hired to cover a position at a specific base. That opening is usually due to a medical condition of a pilot that is expected to be resolved In the future. Once that person returns you will be used as a regional or national relief pilot. When hired you will sign a training contract during Indoc that obligates you to stay with AMC for a year. I won't argue the legalities of such contract here, that's a whole different thread. After a year you are free to resign.

I was a temporary hire for a base. After 4 months at the base my position became permanent when the pilot I was covering for lost his medical for good. 

How many opening currently at AMC? Med Trans has 52 pilot slots, checkout their float pilot positions, good benefits ans travel allowence.

Divorcees.  Military retireee money chasers.  Young, single guys looking for adventure.  People with marriages who don't want to be together.  Or people who know there's a base right where they want to be but there's no opening and want to get "in" by taking a temp company position until a position opens at their desired base (but beware, this can backfire if that's your strategy.

National/Regional Float positions are good for anyone who needs more cash (you'll make way more in those positions).  But beware: it will take a toll on the marriage if you do it too long.  The money's not THAT good to make it up to the wife/kids.  

you're saying there is a dollar amount that makes it worth it to take a job that has you away from your family for 9 out of every 14 days
