allocating
any budget money for including TIS in the mix as part of the upgrade. "

It's really disappointing that this government industry partnership only goes one way. Why would industry produce and pilots buy these boxes it the FAA shrinks its services? TIS is great but not very useful if the coverage is so spotty that you can seldom depend on it. These are the people who are going to give us free flight?
