Why ever would you want to take a small baby up for a joyride in a GA aircraft
Possibly because it would leave them with one of their fondest ever childhood memories, as happened to me when my now deceased grandfather took me with him in a c172 when I was 6years old - it was my first ever flying experience and I remember it fondly.
I took my 4yr old daughter flying for the first time a few weeks ago, she now wants to fly with me every time I go!
I'm aware of the risks (I fly for a living), but I take calculated risk, which to be fair is what we all do as we go about our everyday lives. I want my children to share in my own great life experiences.
I must admit though, I haven't taken my younger son flying yet, mainly because he is still far less independent than my daughter and additionally is still not of an age where he easily takes instruction ie keep quiet whilst on the rt. distraction management is definitely very important if you're to fly with young children on board.
