1. Using Two Hands To Flare Dear Mr. Machado: Greetings Raymond: Dear Rod: Dear Tina: Hello Rod: The problem is time. You need to slow down the clock during the roundout, which would help you gauge your height above the runway. Did you know that your airplane has a built in time machine designed just for students having landing difficulties? It does. It's called a throttle. Instead of flaring with power completely off, leave a little power applied during the roundout and subsequent flare. You'll immediately notice that your runway closure rate decreases, which gives you more time have more time to flare. Upon touchdown, immediately reduce power to idle. Keep in mind that flaring with power applied makes it easier to float or overcontrol during the flare. So only use this technique with your instructor on board. Don't use it on short runways, in strong winds or when obstacles are present. Once you have a feel for the mechanics of the flare, you won't need this application of power anymore. I've used this technique with great success over the years. Students seldom take more than an hour in the pattern to acclimate themselves to the flare. Perhaps the biggest drawback to this time-distorting technique is that it has no effect on the Hobbs meter. Don't worry, I'm working on that problem. (Note to CFIs: using power for landing is done as an intermediate step to help students learn how to flare. Just to be clear about this, I'm not advocating power-on landings to touchdown as the norm.) Dear Flight Training: Greetings Michael: Unless the airplane’s manual suggests otherwise, try a final approach speed of 1.3Vs (that’s 30% above the stall speed for the flap configuration used). Now the airplane’s operating close to the bottom of its drag curve. Increasing the angle of attack for the roundout and flare results in an increase in induced drag, which minimizes your chance of floating. Additionally, if the airplane isn’t properly trimmed on final approach, it’s very easy to over control during the flare. When I make an approach, the airplane is typically trimmed for a speed of 1.3Vs. I maintain that speed with a light touch until I’m ready to begin the roundout, which normally occurs about 20 feet above the runway. At that point I raise the nose slightly and the descent rate decreases, but the airplane continues to descend because of the increasing drag. If the airplane is trimmed, it usually takes no more than two distinct attitude changes to land the airplane: the roundout and the flare. Here’s something else to try. Have your instructor hold your right wrist with his or her left hand and flare the airplane for you as you hold the controls (don’t let go while he’s doing this. He’ll never speak to you again if you do). This technique imparts a sense of the pressure and timing necessary for a proper flare. Dear Rod: As a practical matter, it’s better if the student has one hand on the yoke and the other on the throttle during landing. Of course, certain airplanes like the Cessna 182 and 210 often require lots of elevator back pressure during the flare. I had a petite female student who had a similar problem in her Cessna 210. First, your student won’t be arrested by the yoke police if she uses two hands to flare. The only law that governs how you flare an airplane is the law of gravity. Nevertheless, it’s always a good idea to have one hand on the throttle because it provides immediate access to engine power. So, if she has to flare with two hands, then so be it. I can assure you that if she needs to add power quickly, she be able to let go of the yoke with the right hand and slap the throttle forward in no time. Another solution is to let her use trim during the flare. If the airplane has electric trim, she might be able to simultaneously flare and provide nose-up trim with the left hand while keeping the right hand on the throttle. If the airplane has a manual trim wheel, let her flare with the left hand while applying nose-up trim with the right. This helps reduce the heavy nose-down stick forces experienced during flare. But this method creates a potential problem: if she’s forced to go around during the flare, then the full application of power can cause excessive nose-up pitch. I solved this problem by having my Cessna 210 student begin the go-around by applying three-quarter takeoff power, adding sufficient nose down trim, then applying full takeoff power. There’s nothing unsafe with any of these procedures. After all, the alternative is for your student to give up flying. That’s not much of an alternative in my book. Dear Flight Training: Dear Rod: In regards to solo, I find that consistency is the most important factor in determining whether or not a student is ready. If students are consistent in their performance, then I can rule out luck as a factor in their flying ability. Even if students make safe but firm landings, all that matters is that these landings are consistent. Of course, these landings shouldn’t be so firm that we end up looking like graduates of the Quasimodo posture school. Nevertheless, I’ll solo a student who makes 10 firmbut safelandings in a row, while refusing to solo someone who makes nine greasers followed by a landing where I have to grab the controls to prevent damaging the airplane. Finally, one of the most helpful things you can do to identify when students are ready are ready to solo is to ask them. Yep, this works¾most of the time. Based on my experience, you’ll find that 15% of your students will say they’re not ready when they are, 10% will say they’re ready when they’re not and 75% will tell you when they’re actually ready. I remember hearing an instructor call the tower and say, “Tower, I’ve got a student who’s ready to solo here.” While the mic was still keyed, I could hear the student in the background saying, “Noooooooo! I’m not ready yet.” How do you weed out the 10% that are not ready but think they are? I’ll bet money that the majority of these students aren’t consistent in their flying performance. Dear Rod: Mr. Machado: Now she is very unsure what to do. All the confidence that she built up has totally evaporated. She has no trouble flying with me or going out with an instructor. While she won't admit it, I think she is scared to death to be alone in the plane. How can she regain her confidence in this situation? Greetings Tom: In your wife's eyes, she was attacked by a problem that scared her. So, the first thing to do is understand the threat, then learn a little aviation kung fu to defend against it. It sounds like your wife experienced something known as a porpoise (the tuna-free kind). Porpoising can occur if a pilot attempts to force the airplane onto the runway at a higher than normal speed. This allows the nose-gear to contact the runway slightly before the main gear does. It can also occur if a pilot lands hard on the main gear, resulting in the airplane pitching forward onto the nose gear. Either way, the airplane responds by pitching up and becoming airborne. The pilot typically reacts by applying too much forward elevator pressure, resulting in the nose gear, once again, making hard contact with the runway. The cycle repeats itself, often with more devastating oscillations, sometimes resulting in a damaged nose gear. Of course it doesn't have to end this way. Pilots can learn to handle this problem by having their instructor simulate porpoising on landing, then practicing the appropriate defense. Given a slightly higher approach speed, the instructor can simulate the initial bounce of a porpoise by letting the main-gear wheels touch the runway (not the nose-gear wheel!), then pulling back on the yoke gently enough to raise the airplane two feet into the air. At this point, the student, who has followed through on the controls, should take over and practice the recovery. He or she does so by continuing to flare the airplane instead of shoving the yoke forward, which caused the porpoise in the first place. This means that elevator pressure must be applied so as to prevent a further climb as well as a rapid descent. Of course, the instructor should demonstrate how and when to use power to maintain sufficient speed during this maneuver. As a final maneuver, the student should be shown how to go around from the top of the porpoise when landing is no longer an option. This is how a little aviation king fu can prevent chop suey gear. The success of this solution, however, lies in how the problem is packaged. Make sure you identify the problem (the porpoise) as a specific event with a specific defense. This eliminates the mystery and provides your wife with a means of controlling her destiny in an airplane. While there are several other ways to increase her confidence, I believe this approach will be the most beneficial and have an immediate effect. Dear Rod: Howdy Rod: I think that I'd handle all future students like salespeople handle a client's most common objections: up front. Specifically, address this difficulty with your students during the first few hours of flight training. Address it in a way that educates but doesn't scare them. This should provide some degree of innoculation against the effects of exaggerated hangar tales. Regarding the difficulty with the students you now have, try this. Solo them at another airport with a longer runway, under calm conditions (in the morning, for example). After they’ve landed a few times on a 3,000 foot (or longer) strip with no obstacles, they should be better equipped to handle your home airport runway. I think it's important to emphasize that a pilot never needs to land if things don't look right. He or she can always go around. Perhaps you should place more emphasis on the go-around as a vital option when things don't look right. Make it the rule, not the exception. Do at least two or three go-arounds on every lesson in the pattern. Let the student see them as being a vital option instead of the failure to fly properly. And emphasize that a go-around doesn't represent a personal failure or a lack of airmanship. It's simply another maneuver. You might also give your students the option of landing at another nearby airport if they don’t feel that the conditions are comfortable at the home airport. In other words, solo them at a nearby, easy-to-land-at airport, one within 25 miles of the home airport. Give them instructions on how to fly over the route from the home airport to this nearby airport in accordance with 61.93. Then, solo them at this airport. This way, if they return from a solo to the home airport and don't feel they can land safely, there is always the option of landing at the nearby airport. Yes, someone would have to come over and pick them up, but this would last only a short time before they gained enough confidence to handle the home airport. I believe it's important to give your students options. Give them a few alternatives for handling their discomfort. Make sure you're not conveying your personal landing fears to your students. If they see you tensing up or getting edgy during the landing, they can't help but interpret this as a sign of danger and risk. It's very easy for instructors to convey this message without realizing how it affects their students. Dear Mr. Machado: Greetings Rod: One time during a landing flare I said to the pilot, “Rabbit on the runway, go around now.” Knowing my reputation for this ruse, the fellow glimpsed over the cowling at the fictitious rabbit and said, “Hasta la vista, baby.” Dear Mr. Machado: Dear T.M.: Make sure that you're not using too high an approach speed when crossing the threshold. This is the single most common mistake made by pilots during the landing flare. Excessive speed combined with excessive power can easily lead to floating. I recommend crossing the threshold at no more than 30% above stalling speed for the airplane's current weight and configuration (unless a higher speed is necessary for safety reasons). Additionally, when strong thermal activity exists along the runway, it’s often necessary to be more assertive with the controls during the flare. You may even need to add power and slightly muscle the airplane back onto the runway under these conditions. Pilots operate at a great disadvantage when they assume that they should “always” handle the controls in a dainty and delicate manner. Strong thermal activity often requires you to respond assertively and firmly with the controls. In other words, this might not be the time to use your pinkies to fly. So be prepared to make the airplane do what you want it to do. Opt for airplane control and don’t worry too much about making a gentle, smooth landing under these conditions. Dear Mr. Machado Over the years I found two techniques that work well for this type of problem. First, take some foam rubber (about an inch thick) and wrap it around the left grip of the control yoke. Secure the foam with one or two rubber bands. The reactive pressure of the foam seems to help remind students to relax their grip. Be prepared to use a double wrapping of foam if the student's hand is the size of a car's hubcap. And don't get too creative with this idea. I actually had one fellow tell me that this technique works better when a few thumb tacks are placed inside the foam. Remember, we're here to teach flying, not give acupuncture treatments. Finally, you can use the old, tried and true method of placing a pencil under the student's middle finger as he grips the yoke. A tense grip means pain. This works well, especially if you need smaller pencils. I knew one CFI that used a carbon-nickel steel Harley spoke instead of a pencil. You can imagine how much that hurt! He claimed that all he had to do was show the spoke to his students and their hands melted on the controls. Mr. Machado: When I fly, my instructor has me at 85 knots on downwind, 80 on the turn to base, 75 on base, 70 on the turn to final and 65 the rest of the way in. If I calculate 1.5 times the 172's Vso (44 knots dirty) I don't get anywhere near the downwind speed of 85 knots. Adding to the confusion above, I flew with another instructor who insisted that the entire pattern be flown at 70K. As a student pilot, this bothers me. It seems as though every instructor has a different speed to use for different parts of the pattern. What speeds should I use?
First, there's no regulation requiring that small GA airplanes fly the pattern at any specific speed. As you grow more proficient, the speeds you use will vary somewhat based on traffic, your comfort level, quirks of a particular airframe, and a number of other factors. The "proper" final approach speed in a more-or-less normal pattern would not serve you well if you'd just flown a downwind greatly extended by heavy traffic. There are certainly speed recommendations for pilots to consider, and they're a good starting point. The speeds given in your video certainly jibe with what the FAA recommends, and these are certainly reasonable speeds to use, too (unless the airplane's Pilot Operating Handbook suggests otherwise―so make sure you know the Tao of POH). Using a speed of 30% above stall (1.3 Vso) in calm air is a good speed for final approach, too. This speed reduces your chances of floating during the landing flare. On the other hand, it doesn't seem reasonable to fly the entire pattern at one speed (70 knots). This may be inconveniently slow for the downwind leg, and a tad fast for the final approach. It may also be excessively challenging for a student pilot to have an additional speed requirement for the turn to base leg (i.e., 80 knots in your example) and for the turn to final (i.e., 70 knots in your example). Using five different speeds to fly a pattern might unintentionally train your attention on the airspeed needle in lieu of looking for traffic and holding a specific attitude. Nevertheless, I don't want to override your primary instructor's rule here. He or she is the ticket to your ticket. Do what he or she wants until you get your license. Then you can experiment with other techniques to see what works best for you.
Dear Rod: Dear Buddy: Simulations can be used to recreate the most important aspect of landing―the flare. After the completion of basic airwork it takes an average of eight hours (6 to 7 lessons) for a student to become solo-proficient at landings. The question is, "Why does it take eight hours to learn to land an airplane?" It’s because so little time is actually spent in the landing flare. During an actual landing the student spends approximately 12 seconds in the landing flare. The flare is the time when a student can more easily see the results of his or her control input and the resultant airplane response with respect to a fixed reference (the runway). If it is possible to accomplish 10 touch-and-goes in one hour (6 minutes per T&G), a student will acquire approximately 120 seconds or 2 minutes worth of flare experience in one hour's time. Now that's not much of a payoff for one hour's worth of flight time, is it? If that student takes 8 hours of time to acquire to solo proficiency at landings, then he or she has acquired approximately 16 minutes of landing flare experience. It's a wonder that students can learn to land at all with only 16 minutes of experience actually spent in the flare condition! Therefore, creative instructors look for ways to simulate more time in the landing flare. Many years ago an instructor with the Strategic Air Command explained how he helped pilots check out in a new airplane faster by having them fly along the runway at the height, attitude and airspeed normally used for the landing flare in that airplane. Doing this increased that student’s exposure to the flare condition and dramatically lowered the amount of time that student took to learn how to land. The same technique can be applied with great success by general aviation instructors. Here’s one way to do it. Begin by having the student fly the airplane above the runway at about five feet and at the airspeed normally used when beginning the landing flare (you'll probably have to set the airplane up in this condition for the first few passes). Plan on making several passes with the airplane in this configuration. On subsequent passes have the student lower the altitude to two feet. The student will quickly acquire experience with control input and the resultant airplane response. Be cautious! Do not to let the airplane stall nor get too close to obstacles in the departure path. Use the longest runway in your area for safety. After a half-hour of this activity, have the student fly a little lower by asking him to keep the wheels six inches off the ground while in flare attitude. Mention that if the wheels accidentally touch the ground at anytime, the power should be immediately retarded and the nose gently lowered to the ground. Since six inches is all but impossible for a student to identify, this will certainly lead to a landing under controlled conditions.
