N/A

Detailed steps to reproduce the issue encountered:

Fly level, throttle back, flaps down. Notice lack of drag, and unchanged descent rate. Try same maneuver on GNS 530/430 version and compare results. The extra drag is very noticeable on GNS 530/430 version, as expected. Short landings are almost impossible to achieve on Stock version.

Provide extra information to complete the original description of the issue:

In a comparasion between stock and GNS equiped version of ATsimulations An-2, they handle a bit different not only with flaps, but the GNS one respond different to prop pitch and loose speed different compared to the stock, it’s a bit faster also. Also, it’s noticeable that they have different speed information on aircraft selection menu.

Yes

Provide extra information to complete the original description of the issue:

This is 100% true. On the base version of the plane it was difficult to get the plane to slow down and descend on approach. With the GNS version, I was finding myself sometimes actually dropping short of the runway while using the same power & flap configurations as before.
Further, I believe the same issues may extend to the flight models of the Float & Ski variants. If you look at the cruise speeds of the different variants in the hanger, you’ll see that the GNS version’s is 20 knots faster than the other 3 variants. This should definitely not be the case if only the avionics have changed. It seems like something is messed up.

Yes.

Provide extra information to complete the original description of the issue:

Even when the throttle is closed and flaps are full with approach speed of ~100km/h, level “over the fence”, aircraft does not slow down. No change when increasing flap deployment. This is not normal.

Yes.

Provide extra information to complete the original description of the issue:

Nearly impossible to decelerate the aircraft on approach. Looks like it’s working in “modern version”.
Standard version is drag-less. Followed checklist, still hard to get less than 120km/h on touchdown.
