TL;DR: Modernized Soko J-20 Kraguj

Please at least read the Operation section!

The T-20 Gavilan is a single seat beginner level trainer and can perform COIN operations. It is heavily based on the Soko J-20 Kraguj. The J-20 is a COIN aircraft of Yugoslav origin which was first flew in 1962. The T-20 performs best at low altitudes against light ground targets and can be used for reconnaissance. The rugged fixed landing gear allows it to land on unpaved/unprepared runways with ease.

The T-20 Gavilan is not a true replica since it has been modernized and most minor details have been changed or omitted.

The T-20 is perfect for teaching new pilots the basics of flight due to its slow speed and forgiving handling (basically you have to try really, really hard to spin it). The Wright Civil Air Guard uses the T-20 to train pilots on how to patrol Wright's airspace and territorial waters. Pilots must qualify by flying at least 10 hours, intercept 5 airborne targets only using the Datalink, and passing Convoy Chaos three times with no damage. Pilots will then be able to train on the QAS T-35 Falcon.

Datalink

Due to the lack of a radar, the T-20 uses a datalink. It gives information on the general location and orientation on a selected target. It is not as powerful as a radar since it can only track targets within 20km, but it has the added benefit of providing 360 degree coverage. The compass indicates what quadrant the target is in relative to your position.

1.Datalink Off.
2.Tracking the USS Tiny from Wright Airport. USS Tiny is in the west quadrant while the aircraft is facing north
3.Merging with a target drone. The drone is in the northeast while the aircraft is also facing northeast.

The Kraguj uses the Lycoming's GSO-480 engine. The Gavilan uses an engine similar to Lycoming's TIO-540 engine. The TIO-540 provides more power compared to the GSO-480, however fuel consumption is increased.

Note that the indicated horsepower and propeller thrust are not proportional.

Takeoff

Set flaps to 10 degrees, set trim to 50%, then Throttle to 100 percent. Liftoff should occur at 170-190 km/h. Wait until 8 degrees of attitude to reduce flaps to 5 degrees. Climb rate should be within 9-12 m/s.

Landing

When on approach, speed should be less than 190 km/h. When on final, reduce speed to 150 km/h while gradually applying flaps to 20 degrees. On short final, flare to touch down at 130 km/h.
