I am with Standard Life and took out the cover for just the same reason as you. Make absolutely sure when filling in any proposal form that they understand that you are doing flight training.
A lot of insurance companies seem to have an exclusion clause for flying unless as a passenger on a commercial flight, also make sure that any of your hobbies are covered if you are into diving or base jumping or anything considered slightly risky!! You should be ok if you take up knitting though!!
It costs me about £27 per month for a higher amount than you possibly want covered.
