"Air Chart is the top value, Air Chart offers the best combination of good-value pricing, timely information and painless revisions."
– The Aviation Consumer, May 2001

"I am an air traffic controller (now at Washington DC National, before that, Roanoke). I have been an Air Chart user for five years for my personal flying. Your Enroute Atlas is a dream come true!! Now I KNOW I always have a chart for anyplace I might want to go."
– David E. Robertson, ATC

"I continue to believe that yours is the best and simplest of IFR systems. Also, the Enroute Atlas‚ convenience and auxiliary information are terrific!"
– Cliff Cowen, Chief Pilot, Flivver Aviation, Brighton, CO

"I am an 8000 hr. ATP pilot flying for a major airline on a B727, but also fly a lot of IFR X-C personally all over the U.S. ... We really like your service, keep up the good work!"
– Kevan Corder

"My own personal full-color map display, at a foot square, is bigger than just about any laptop or notebook computer, covers the entire US and part of Canada with flawless detail and resolutions, weighs only about two pounds, is less than an inch thick and runs forever without a battery change: Howie Keefe’s terrific new Aviation Topographic Atlas from Air Chart Systems. It costs all of $99 if you buy it alone - or a lot less if you get it in conjunction with Air Charts’ other VFR and IFR map products.) Two things are for sure: I’m looking forward to flying with the newest and niftiest GPS I can afford ... but I’m not about to throw out those paper charts, or deprive myself of either the situational awareness, or the enjoyment, that comes from looking out the window!"
– Peter Lert in Air Progress, June 1997
