acs slow flight

As the speed slowed to a dangerous level, setting off the stall-prevention system, he did the opposite of the proper procedure, which led to the crash, these people said. [FAA ACS FAQ] This new FAA focus developed directly from accidents such as the Colgin 3407 crash in Buffalo, where the pilot decelerated rapidly into a high AOA configuration and aggressively held the plane in an aggravated stall defeating the stall protection safety devices and resulting in 50 deaths. Pilots instinctively react to unfamiliar situations in the manner in which they were trained. Flight Maneuvers C-172R/S . Renslow. 1. I fear the current specification will not allow slow flight to be deep enough into the induced drag curve to demonstrate “mushing with power” where you must lower the nose to reduce drag and obtain a climb (that is an eye-opener) It takes a very competent educator to handle this training correctly and build understanding (and why SAFE works hard to improve aviation educator excellence) Thanks for your comments! ). The stall warning horn could clearly be heard from the ground as the pilot circled. Formerly a 141 Chief Instructor for over 25 years, with a Gold Seal CFI. David started flying at 16 and has logged over 15,000 hours. To me this seems like a one off pilot error more than a symptomatic problem with the entire flight training process. Search the world's information, including webpages, images, videos and more. A private pilot checkride still requires a full stall break whereas a commercial checkride requires that the applicant recover at the first indication of a stall, i.e. The result is that pilots of large airplanes are loosing control of their aircraft at high altitudes and holding their airplanes in a stalled condition all the way to the crash cite. Well, I get a loud, blaring stall warning horn on (almost) every landing, and I’m certainly NOT going to push the stick forward then! ACS Focus Team Slow Flight and Other FAQs The ACS Focus Team has been asked many questions about the topic of slow flight. The ACS just says 5-10 knots above 1G stall speeds. “The ACS now specifies slow flight as, an airspeed, approximately 5 – 10 knots above the 1G stall speed, at which the airplane is capable of maintaining controlled flight without activating a stall warning.”. The stall warning horn should be on during slow flight. According to the ACS, for slow flight the pilot should establish and maintain an airspeed at which any further increase in angle of attack, increase in load factor, or reduction in power, would result in a stall warning (e.g., aircraft buffet, stall horn, etc. I have seen this numerous times where a pilot inadvertently stalls the airplane at high altitude and reacts to the stall warning horn by trying to power-out of the stall while releasing little or no elevator back pressure. Background: Loss of control in flight continues to … For years, the testing standard for slow flight stated that the applicant must “establish and maintain an airspeed at which any further increase in angle of attack, increase in load factor, or reduction in power, would result in an immediate stall.”  The new ACS changes the words immediate stall to read stall warning. I recently had a discussion with one of the FAA representatives who took part in a committee to increase general aviation safety. Slow Flight and Stalls, page 54 of the Private Airplane ACS, the Skills section contains in part $$\begin{array}{l|l} \bf{Skills} & \text{The applicant demonstrates the ability to:} \\ \hline \textit{PA.VII.A.S2} & \begin{align} \text{2. } It does appear though that on the way to the alter, one critical vow was transformed and quietly embedded into the new ACS. Share this page on: Airman Certification Standards for slow flight, and what to do if the stall warning system sounds! Commercial ACS – Area of Operations VII Slow Flight & Stalls. For a private pilot, that might sound something like this, “There’s the horn. The FAA ACS Focus Team has issued a Safety Alert for Operators (SAFO) for the slow flight maneuver required on the Private Pilot Practical Test. Pre-maneuver checklist . Flight at minimum controllable airspeed is flight at a speed such that any further increase in angle of attack and/or load factor will cause an immediate stall. In section VII. 4 - Slow Flight, Stalls, Spins . ACS Slow Flight - MzeroA Flight Training. An accident case in point is Colgan Air Flight 3407 where the pilot of a Dash 8 Q400 reacted to a stall warning while the aircraft was in the approach configuration and at about 2300 feet, plenty of altitude to recover if only the pilot had pushed rather than pulled the yoke forward. If you are not yet a member, please Join SAFE and support our mission of generating aviation excellence in teaching and flying. ACS & Slow Flight Asked by: laminar 2131 views FAA Regulations , Private Pilot Does anyone has insight as to why the FAA opted to drastically change the standards for slow flight in the new "ACS", from the previous "min controllable airspeed" PTS standard, to what now says that activating the stall warning would be disqualifying? is creating quite a dust-up in the flight training community. a. Teaching “Average” Prevents Effective Learning. The … Preventing a stall becomes secondary to immediately stopping a descent by pitching-up, adding power and performing a go-around maneuver. In other words, when an applicant performs slow flight, he or she must not allow the stall horn to blare during the maneuver. They were created to update elements of the private pilot and the instrument rating knowledge exams, both of which were widely considered outdated and replete with confusing questions that did little to evaluate a pilot’s decision-making or risk-management skills. Upset Recovery Training (URT) goes a long way to give pilots the experiences they would not otherwise see and allows valuable insights into how airplanes tend to behave when operating outside of their normal operating envelope. As most flight instructors know the FAA recently changed the requirements for slow flight in the private pilot ACS. The FAA does not want pilots in training flying with the stall warning horn blaring with the supposition this will lead to ignoring this critical warning device. 4) I consider "slow flight" and "flight at minimum controllable airspeed" two very different things. PPL ACS Explained in Detail. Most don't know the real difference between a spin and a spiral, and fail to grasp the fundamental relationship of these with aerodynamic stalls. Although no one likes change, when I hear stories like that, I realize that the new ACS is a safer standard. From the Wall Street Journal May 11, 2009; An aerial view of the site where Continental Connection Flight 3407 crashed into a home on Long Street in Clarence, N.Y., is seen Saturday morning, Feb. 14, 2009. The following is for quick reference only. Does the ACS Focus Team have an e-mail address? It’s frightening to observe this especially when the pilot is obviously confused as to why the airplane is not recovering the same as it did in performing the standard approach to stall recovery. So the FAA wants to inculcate in every student pilot an automatic ‘push the stick forward’ response to every bleating of a stall warning horn. ).” To recap, for slow flight, fly at an airspeed just above the stall warning. Slow flight should be of short duration because of the insufficient airflow for engine cooling. NO! Even during simulated emergencies, like an engine failure, there is no reason to rush into any… ». Please “follow” our SAFE blog to receive notification of new articles and please write us a comment if you see a problem or want to contribute an article. Properly performed, the maneuver should not activate the stall warning system at all. We have also included responses to a … The problem with this is that most fatal stall/loss of control incidents involve a stall at higher altitudes where excess altitude can and should be traded for airspeed and aircraft control. Practicing and demonstrating pilot knowledge, skill and control in this slow flight area of airplane operation is critical to flight safety and is the holy grail for most CFIs and DPEs. Please mention your flight training experiences and viewpoints. The difference is that now, the applicant is required to speak during the maneuver and announce the stall indications as they happen. Think your way through EACH maneuver and ignore the fact that you’re being tested. Planning (not “Plans”) – Essential to Safety. There is great training value in mastering (and regularly practicing) slow flight with the stall warning horn operating, coordinating your plane carefully at the maximum angle of attack right up to the aerodynamic stall. The PC-12 has a warning/shaker/pusher system. ... FAA ACS - Slow Flight and Stalls (.pdf) FAA AFH Chap. Slow flight must now be accomplished at a speed higher than MCA or Minimum Controllable Airspeed (a speed at which the stall horn is continuously activated). One area that really causes some confusion is the new slow flight and stall standard. The slowest airspeed at which the airplane is capable of maintaining controlled flight without indications of a stall—usually 3 to 5 knots above stalling speed. Mixture - RICH Because of the risks of stall, slow flight can be hazardous specially at low altitude. This website contains Affiliate Links. b. As early as 1989, I became increasingly concerned that our pilot training at my airline company as it did not include stall recovery at altitude and feared that the stall training scenario at low altitude would lead to a negative habit transfer if a pilot became confronted with a stall warning at high altitude. Our slow flight practice is not just an isolated task, but is also designed so that we can learn how the controls feel and how the airplane maneuvers at speeds encountered in the landing process. Task A. But if it is activated, the pilot is expected to take prompt and positive stall recovery measures. Send your comments supporting retaining slow flight in it’s previous (slower) form as an essential part of flight training to the ACS focus team at the FAA Aviation Working Group. The new FAA SAFO highlights this controversy and presents the FAA position. Can anyone clarify the speed that the examiner is going to be looking for on the checkride? Pretty simple right? Stalls, Spins, and Spirals are three flight maneuvers that are frequently misunderstood by pilots. This, however, is not normally trained in the air transport industry. The FAA ACS committee has people thinking that pilots routinely flew around with the stall warning horn activated while not doing anything about it; there is no basis for that argument whatsoever. There’s the buffet. The ATP approach to stall recovery training scenario both involve an imminent stall at low altitude, as on final approach, and recovery dictates a minimum loss of altitude. In all cases, students should refer to and become familiar with the C-172R or C-172S Information Manual and the appropriate ACS or Practical Test Standards (PTS). : //www.macleans.ca/news/world/deadly-stalls-haunt-airlines-as-airasia-investigation-unfolds/ ACS is a Charter member of SAFE the difference is that now, only private!
