Stall buffet effect intermittent in F5-E during aerobatic maneuvers

[tqroljoe]

Describe the bug When performing aerobatic maneuvers such as a loop in the F5-E under constant high angle of attack, the stall shudder effect suddenly stops and restarts as the aircraft attitude transitions through the vertical orientation.

To Reproduce Steps to reproduce the behavior:

1. In the F5-E, from level at 400 knots, enter a 3g pull to execute a loop.
2. As the plane completes the first 3/4 of the loop, maintain 15 degrees AOA to ensure stall buffet should be felt.
3. Roughly as the nose transitions from straight down to the last quarter of the loop the stall buffet suddenly stops for 1-2 seconds then restarts.

Expected behavior Stall buffet should be a function of angle of attack and independent of aircraft attitude.

Screenshots NA

System (please complete the following information):

• Windows version: Win10
• Simulator version: DCS Open beta 2.8.2.35759
• SSA version: [SSA Beta 2.5.9]

Additional context This problem has existed for all recent versions of DCS and Simshaker I've used in the last several years.

Thx for the report. Could you please provide a track file thus I can reproduce this issue ?

Hello, I've attached a track file in which I fly two loops. In the first, the stall buffet stops and starts at the first quarter of the loop when the nose is pointing up. In the second loop, the buffet stops at the third quarter of the loop when the nose is down. Let me know if you need anything else. Thanks, Joe

Somehow it was not pasted here on Github. Could you please upload is via the web page? I guess you have to zip it first...
