Yeah Frank. You found our secret.
TAP pays extra to always get the latest and prevously unpublished strip first....
AND they are usually more technical than the ones online because they are drawn for strictly an avation audience.
As for the heading vs airspeed thing:
I had the assistant forman of one of the Helitack crews I used to work with read my radio frequencies instead of the coordinates on the GPS for her position check.
Pam: "Dispatch helicopter 530 current position is 122.9 by 123.025"
Dispatch: "Roger"
I was wondering where she got the numbers from when it finally hit me. On top of that she was a "mapping specialist" .....supposedly....
so you'd think she would have noticed the coordinates not starting with N32 .... or something like that
My mechanic was laughing his @$$ off on the ground especailly because dispatch didn't catch it either.
I was shocked. They would have never found us if something happened.
And since there was no arguing with that woman (long story), I just turned her transmit to some aux schannel that's not turned on and let her think she's still talking
while I was making the position calls myself on the right channel.
