"The Jetline gauges by Reality XP are in a class by themselves. If you are looking for the most accurate, visually most appealing, and dynamically smoothest glass cockpit avionics, this is it! If you have a fair number of high performance aircraft in your hangar, you’ll find that these gauges integrate nicely into most cockpits and in many cases help elevate a good basic panel design to a great flying experience."

"The expectations for this product are pretty high because in their own words, the Jetline 4 is promised to be the industry leading integrated avionics for both regional and business aircraft. When moving around comes the best part of these gauges: the EFIS screens feel as smooth as the real glass cockpit screens, almost regardless of simulator frame rate! So Reality XP has really even exceeded what they had promised. Overall, Jetline 4 is a must, if you like to fly those business jets and/or Saab 2000 etc."

"Addressing Microsoft's omissions, Reality XP has stepped forward with versions of its add-on avionics packages, which promise to breathe new life into the simulator's older aircrafts as well as enhancing third-party add-ons. They provide ultra-sharp, smoothly animated gauges with functionality that goes beyond that provided by Microsoft's instruments."

"The only way to describe the two main gauges is that they are beautiful and put some real world instruments to shame. Apart from actually being readable and therefore usable, the Electronic Attitude and Direction Indicator (EADI) is one of the smoothest gauges I have ever seen in operation. The Electronic Horizontal Situation Indicator (EHSI), on the other hand, is not only good looking, but goes so far beyond what the instrument it replaces does as to leave it eating dust."

"The Jetline Avionics are a very nice enhancement for the Flight Simulator market and I recommend everyone to use it. For pilots who flies aircrafts like the Learjet, the Jetline 4 is an absolute must. I like both Jetline series a lot, especially when flying IFR. Also, the King Air or similar aircrafts make IFR flying much more fun with these add-ons."
