Not really, I change the column labels every year or two when the pattern of my flying changes. Take's a little thought and care, but not much.
For example, it's now about 10 years since I last flew in an ejection seat, but about that time I started to get serious about taildragger flying. So, the "ejection seat hours" column now records "taildragger hours", I can always look back a few (!) pages if I need to check that. Similarly, I did allocate two columns to glider P1/PiC, but realised that I'd never get serious enough about gliding (for the moment...) to go solo, and this was about the time that I got involved in experimental simulator assessments, so the "glider P1" column [empty] got relabelled "simulator exp."
It's easy enough, honest! Right now, columns 1-14 of my logbook (an old Pooleys commercial) read:
- Microlight, 3-axis (Dual, P1)
- Microlight, weightshift (Dual, P1)
- SEP (Dual, P1)
- Other dual (Glider, SLMG)
- Simulator (Experimental, training)
- Night
- Instrument
- Flight Test Observer
- Tailwheel
Ask me in a year, it'll probably be slightly different (particularly as I'm hoping to finally get around to my MEP next summer).
