Stalls – One “Dangerous” Maneuver We Can Practice Safely, Consistently
It’s no secret that stalls have led to some deadly accidents in aviation. A thorough 理解ing of the aerodynamics of a stall, how to 避免 situations that can lead to a stall, and how to recover from a stall are all required elements of a pilot’s education. 当飞行员, 十大网赌网站大全需要确认, 避免, 如果太晚了, recover from a myriad of different types of abnormal and emergency situations. Many of these are difficult or too dangerous to replicate in the real aircraft. Fortunately, stalls are one of the few situations we can practice in the aircraft safely. Yet they still plague our community with accidents – why is this?
Not 理解ing the aerodynamics at play that lead to a stall seems to be a common theme during evaluations and hangar discussions. Furthermore, not having a grasp of the types of situations that can lead to stalls is even worse. A pilot who finds themselves unexpectedly stalling an aircraft won’t help the situation by reciting the aerodynamics of reverse airflow, 攻角, 等. They’re going to be looking for a way to get out of the stall. This is not to downplay knowledge of aerodynamics – which is crucial to 理解ing the ‘why’ behind stall recovery techniques. However, we do need to 理解 ‘how’ and ‘when’ a stalled condition may develop.
Simply going out and practicing a stall at altitude per the Airman Certification Standards (ACS) and then calling it a day seems to only placate the demands of the checkride. Pure demonstration is not the intent of the maneuver and instructors and students are shorting themselves by stopping the lesson there. The feel, noise, and sounds leading up to and recovering from a stall are just the beginning. Taking those sensations and adding them to a scenario will have a greater impact and place greater meaning to why we practice stalls. While the base-to-final stall/spin scenario is commonly discussed, it is not practiced. No, we’re not condoning practicing this in the pattern, but pretending to fly a pattern at a safe maneuvering altitude in the practice area is a great way to demonstrate an all too common scenario that continues to plague our list of NTSB reports. Just be sure that if you do practice scenarios with the intent of taking an aircraft into a spin, that the aircraft is approved for spins and is within the center of gravity limits per the manufacturer’s operating handbook.
The base-to-final scenario is just one of numerous scenarios instructors and students can tap into. When taking the practical exam to become a Certified Flight Instructor (CFI), the applicant is required to demonstrate numerous types of stalls, not just power-on and power-off stalls. These include accelerated stalls, elevator-trim摊位, 交叉核对摊位, 和二级摊位. If your instructor has not demonstrated these to you or had you practice them, ask why. Don’t limit training to what’s required by the ACS.
教练, take note: how you present stalls to student pilots will forever affect how they view, 理解, 和处理摊位. Many people are afraid of stalls and handle them with very rigid, mechanical responses that in many cases can make things worse. Nine times out of ten this is a result of their first lesson practicing stalls involving their instructor, “dumping them into the pool” per se, going right through an entire stall series. All the student will remember seeing is a windscreen full of blue sky, 那么所有地球, then all sky again accompanied by lots of engine and wind noise. 请不要这样做. Gradually introduce students to the maneuver by starting with slow flight, 然后迫在眉睫的摊位, and then graduating to fully developed stalls. You’ll reduce a student’s anxiety and better enable them to handle stalls for the rest of their lives.
To reiterate, stalls are one of the few emergency scenarios we can fully experience in the aircraft. Take advantage of that fact – don’t let the ACS be your only motivation to practice them – and ask your instructor for more. Search for a few accidents that involved stalls. Avoid asking the question of why they didn’t recover and instead dig into the events that led to the situation. By incorporating an 理解ing of the aerodynamics behind a stall, practicing stalls beyond the level of the ACS, and adopting the mindset of ‘how can I 避免 getting myself into that situation?’ you will significantly improve your skills as a safe, competent pilot.
