The best way to satisfy your partner is to simply make out that your not enjoying yourself, If your partner thinks that you get pleasure out of doing something that doesn't involve her then your in big trouble.
Take your partner out for a romantic meal and tell her late in the evening that it has always been your dream to fly her to a deserted Caribean Island, just you and her with the sun and the sand, hold her hand and look into her eyes as your saying it. The next day make her breakfast and then say to her with a 'sigh' that you really ought to do a bit of flying practice today on the computer. When she protests be sympathetic but say " look its either this or real flying lessons".
