Logbook error corrections
So i had a couple questions on some logbook errors ive made over time. I decided to buy a second logbook after finishing my training, so that i could have a training logbook and a professional logbook, separating the two times of my life. With that said i made a silly error of not carrying over the times (ignorance) to my NEW logbook. So i have a second logbook starting from 0 errors. Any suggestions on how to fix this? I plan on a regional airline eventually so keeping that in mind. Secondly, I've heard of white out and lining out errors. Which do 121 airlines prefer? Thanks in advance!
Also, if you do have an error early on in your logbook, how do you fix that over 5+ pages of entries? I.E., 2 hour error of X-C time entry, but then ive calculated 5+ pages of times without that time entered
