You can also use these call signs for US bombers and fighters flying over Viet Nam.
What's included- Red, White, Blue, Yellow, Black, and Green call signs.
Install- Using EditVoicePack's IMPORT option. Then UPDATE and SAVE. Remember to update your "airlines" voice pack list using EVP's TOOLS> Update "airlines.cfg" option.
You can find your "airlines.cfg" file at the bottom of your Aircraft main folder in FS9. Its handy if you aren't sure what text to enter in your plane's "atc_airline=" line in it's aircraft.cfg file. I've included an example below:
atc_airline=RED
atc_flight_number=65
NOTE: Install ONE vcpmod at a time in EditVoicePack. I use some (but not all) of these EVP files with no issues. If EVP's "ladder diagram" turns red, it means EVP has a problem (usually with the file's GRAMMER). Also check if you've already installed a similar call sign. I have also kept the original author's name intact when possible. Files were created for FS9 but should also work in FS2002 and FSX.
