Product information "Diamond DA20-100 Katana 4X"

The DA20-100 Katana is proof of the old saying "what looks good, flies good". It is a cutting GA aircraft made out of fiber-reinforced composites. Originally designed to be a training craft it is now flown by a lot of private pilots who enjoy the wonderful flight dynamics and its economical costs.

This aircraft for FSX has one of the most impressive lists of features of any product we ever handled. It really makes you feel like owning the aircraft as you got to do the maintenance, cleaning and even decide what oil type to use. If any product made Microsoft slogan “As real as it gets” come true it got to be the Katana!



  • Realistic - Wear and damage can encounter and will be stored. Fluids will be used and the aircraft can get dirty. Maintenance and services are available. Flight hours and landings will be counted and special features unlocked.
  • Simple - No wear and damage will be simulated. Aircraft stays clean. Flight hours and landings are not locked. No special features.
  • Instructor - Aircraft is as new every reload. Wear and damage can encounter or be triggered but will not be stored. Fluids will be used and the aircraft can get dirty. Flight hours and landings will not be counted and no special features are available. Instructor Panels are available.

Awards / Reviews:

Conclusion by the PC Pilot Magazine, Issue Sept/Oct 2011:
"As if the aforementioned features weren`t enough, Aerosoft thought to include an `Instructor` mode which is a nifty utility that allows an instructor to use a second monitor to selectively fail or degrade aircraft systems and indicators. The ability to pop circuit breakers, open relays, induce mechanical failures, and to otherwise challenge students, vaults the Aerosoft Katana 4X from pure entertainment software, to being a useful training tool for students. The all-round attention to detail, additional features, and polish of this aircraft make it worthy of exceptional praise."

Conclusion by MutleysHangar.com:
"I`ve thoroughly enjoyed reviewing this add-on and it is a fantastic addition to your flight sim hangar. You need to bear in mind that it is a complex aircraft (unless you run it in simple mode) and it may not be the best add-on for the more casual simmer.
If you are unsure you can download the manual prior to purchase to get an idea of what to expect. I did experience some teething problems which will hopefully be addressed in a service pack, but the support available via the Aerosoft forums was a great help in sorting any problems. A tutorial flight would have been welcome and is a glaring omission from such a well packaged product. I`m happy to award the Aerosoft Diamond DA20-100 Katana 4X"
