How many other aviation products that used the DAFIF are also going
away? Any yet?

There are a number of GPS systems that depend on DAFIF.

Pilots should write their Congressperson and complain. The DAFIF
charts are paid for with tax money and making them available for
download on the internet costs very little.

There is really no way to get charts of this quality from other
sources, much less inexpensively.

Taxpayers are paying for them and the pilot community
has lost an important resource
