These are great if you are ready to start putting originals in the pages instead of shrunken copies! As you can see, a full size Jeppesen chart slides right in! Now your mission data cards fit, your target photos can get more detail in them, and your attack cards slide right in without making a trip to the copier to shrink or the paper cutter to trim! These are the same construction as the regular, just bigger. Great in extreme temperatures and long lasting.
Spacing on the holes matches up with the FlyBoys KneeBoard with eyelets and Jeppesen charts.Size is 5 1/2" X 8 1/2" - really makes a difference.
