If you are a young pilot with a large amount of debt ie college/ratings, and you blow a medical, it may be worth it. Had a kid on the jump seat the other day with $250k in debt for school and ratings, and my first thought was (after what are his loan payments) what would he do if he couldn't fly anymore and had to re-educate himself in a new career? Problem is what are the premiums on top of school loans, rent, food, car, gas etc? Could you declare bankruptcy on all that debt? Guess it depends on what stage of the game you're in, and what your trying to protect. Obviously, read the fine print, premiums might be less for the younger pilot, but as you age the cost increases. One policy I looked at a former employer really wasn't worth it as the pay out amount goes down and premium goes up asome the pilot ages. Wasn't worth it for the older guy, and long term disability was a better deal. But that all depends on what insurance benefits your employer has and whether or not they consider the loss of a medical as being disabled. Knew a guy who lost his medical, and the insurance company was willing to pay for him to go back to college as it would be cheaper than paying for him until he was able to draw on Social Security. Good luck in your research.
