Checklist for Twin Comanche (Don't Forget To Scroll Down...)

This is a checklist that I made for my Twin Comanche that I printed up on a series of 5 X 8 inch cards

and placed in a multi-page vinyl wallet. I bought several of these wallets in various sizes from AWK Aviation

Checklists and I found the 5 X 8 worked best considering the amount of information involved. Please feel

free to copy this checklist and modify it to your needs. With a few changes, it actually works pretty good

for single engine Comanches as well. If you want to make a copy of this, the best way is to simply go to

Edit up above on your toolbar in Internet Explorer and click on Select All. Then click on Copy. Next open your

word processor program such as MS Word and paste this into a new document. You can now edit

out this opening paragraph and the photo and make any changes that you wish. You can select the amount of text you

want so you can print just one 5 X 8 card at a time and figure out what spacing you want, etc. I print the

Emergency procedures on pink cards so they stand out.

approach cl time received, leave in time

to arrive over fix at that time. If ahead

of ETA hold at fix until ETA. All approaches

are protected.
