Air carrier flight crew reported during a missed approach with speed at V2 and at a 28-degree bank; as the bank angle increased; the stick shaker briefly engaged resulting in the pilot lowering the nose and increasing thrust rather than performing an upset recovery per Standard Operating Procedure.
Synopsis
Air carrier flight crew reported during a missed approach with speed at V2 and at a 28-degree bank; as the bank angle increased; the stick shaker briefly engaged resulting in the pilot lowering the nose and increasing thrust rather than performing an upset recovery per Standard Operating Procedure.
Narrative
During approach; ATC reported tailwinds that exceeded limitations (10Kts). I cancelled the approach request and executed the published missed approach procedure per ATC instructions. The Company Aspen briefing guide specifies that the missed approach be flown at V2; not Vfto or V2go. We started the missed approach well before the MAP. By the time we were at the initial turn for the MAP (RICOK); we were getting close to our level off altitude of 14;200' which required me to reduce thrust in order to not exceed V2. Because of the tailwind; we need to maintain V2 and our maximum bank angle to remain 13.5 DME of the DBL VORTAC. During the turn; the stick-shaker briefly activated but I did not perform the Company upset recovery procedure per the Standard Operating Procedures (SOP). Instead; I added thrust and slightly reduced the angle of attack. Performing the SOP upset recovery procedure would have placed the aircraft outside of protected airspace and dangerously close to terrain. Cause: In smooth air without the gusty tailwind conditions; it is unlikely that the stick-shaker would have activated. But our briefing guide and excellent (recurrent) training prepared us for what to do if it does and to prioritize the missed approach/balked landing procedure over the upset recovery procedure to maintain terrain separation even in VFR conditions. Suggestions: Because of the gusty tailwind conditions; it was necessary to fly the missed approach (as directed by our briefing guide) at V2 and at the maximum bank angle. As such; little could have been done to avoid the stick shaker. Thankfully; Company excellent training provided me and my First Officer the tools to handle the situation to assure an uneventful outcome.
Second reporter narrative
Flying missed approach which requires aircraft to be flown at V2 and 28 degree bank to ensure terrain clearance. The aircraft was already leveled off and power set to maintain V2. As the aircraft bank increased stick shaker briefly engaged. Due to terrain and an effort to remain in protected airspace; PF added thrust and slightly lowered the nose rather than performing an upset recover. Performing an upset recovery per the Standard Operating Procedures would have placed the aircraft out of protected airspace in an extremely dangerous position in regards to mountainous terrain.Cause: Mountainous terrain and strong tailwinds.Suggestion: Continue to teach good pilot judgement in training.
