Compulsion ,
Like many pilots who fly with their spouses I know where you're coming from . My wife and I cover a fair bit of ground during the year, and I also considered her having some lessons , "just in case " , but she indicated that she was happy just to be a passenger. I later thought , even if she did learn the "basics" , would she be able to recall those basics , especially with me slumped over the controls , even if she had had a lesson the day before . As we all know ,its very different learning with an instructor guiding you through the process , compared to being alone in the stressful situation described . Long ago I decided that the best strategy for me was to ensure my fitness to fly (IMSAFE) , minimising the likelihood of that situation arising . We all know that the only requirement for a Pilot Certificate is the ability to drive a motor vehicle , however this doesn't prevent people with many other risk factors from flying . As pilots we have a duty of care to our passenger ,whoever that might be ,and the best insurance against that situation arising is to maintain a healthy lifestyle with plenty of exercise, control our weight within the recommended range , a good diet and moderate alcohol consumption when flying .It is also wise to have regular tests including blood analysis , particularly as we get older . Many of us take passengers on "joy flights" , do we ever consider that they should be able to land in an emergency ? Of course not. If you happen to feel unwell during the flight the best strategy is to get down as soon as possible ,don't ignore the warning signs and press on ,even if that strip below you is in the middle of nowhere . I also consider it important for your spouse to be able to use the radio in an emergency .
