Anyone tried this with a family?
Yes I have. I work for Keystone out of PNE and I am willing to say the name because they make no attempt to hide any of this (which is good). I am married with no children, nor any plans for any in the near future. It's possible to do this job and have a family, but it's not what I would call easy. My wife is very understanding and accepting of my career choice, which makes a huge difference, but it's still not easy on us. Sometimes we work from our base (PNE) which we commute in daily for, and other times we deploy onto the road. Everyone's experience will differ because it all depends on the projects we have running and where they are. I was in PNE for about 3-4 straight months last year where I was home every night. Then I flew across the country and was in CA for 3 months straight. It just depends on what we have happening.
For me it's not the time that I'm flying that's the problem, it's the time I'm sitting in a hotel room waiting on weather or MX. At least if you're flying you know you're getting hours, working towards something, but sitting on the ground just feels like torture because your not getting work done, and it's just dragging out the time until you're back home. Time differences can also make things a little harder, for me it was a the 3 hour difference when I was in CA. It's not a huge difference, but it's just enough to make it annoying, especially if your spouse has a busy schedule of any sort.
Time off wise we have a very understanding flight department manager right now and we can schedule time off just about anytime with enough notice (spring can be a little difficult). When I get ready to go on deployment, I usually schedule something for 2-3 months out, just to be sure that I get back for a little bit to see my wife. After a year and a half it's starting to wear, but usually survey is a 2-3 year job, then you have your hours and move on.
Hoped this helped give some perspective, even if it is a bit bleak. I wan't to emphasize that it IS possible to do. I'm not divorced yet and I expect another year - year and a half in this job. It will certainly make your relationship stronger if you can get through it.
