Crashes on approach to the deck were regular , if infrequent, but this naval aviator would have many more friends alive now if their Modships (Navy) could have been persuaded much earlier to fit Angle of Attack indicators. After fitting these invaluable gismos the deck landing accident rate decreased quite dramatically. So.. if you can do it, fit one. Patrick P.S. There is a very good argument about how aeroplanes fly and the latest thoughts are not based so much on the shape of the wing producing lift because of airflow over longer surfaces, reduction of air pressure on the top surface etc (Bernouillie's theorem and all that) but is pretty much dependent on angle of attack. You can built a model with absolutely indentical wing profiles, top and bottom and it will fly perfectly IF THE ANGLE OF ATTACK IS RIGHT! Look at the way in which most aircraft are perfectly capable of flying inverted - but notice how the angle of attack is much greater than when the 'right' way up - to counteract the wing profile.. ________________________________ Message 2 _____________________________________ Time: 02:02:09 AM PST US From: "Mike Gamble" Subject: Europa-List: Naca / Paint --> Europa-List message posted by: "Mike Gamble" 1.

The airspeed will vary with various parameters BUT the angle will stay the same. Thanks Ferg, can I add one more thing? The Airspeed is useless for decision making on finals, if its wrong, its because something changed at least 15 seconds earlier. If its too slow you already fell out of the sky! Attitude is the thing to watch or better AoA. Just wish Mark would do AoA instead of airspeed Graham ________________________________ Message 4 _____________________________________ Time: 03:09:22 AM PST US From: "Colin John Howard Richardson" Subject: Europa-List: Angle of Attack --> Europa-List message posted by: "Colin John Howard Richardson" Hi Fergus, and others. A wing will stall at the same angle of attack (AoA) at any weight, provided the wing configuration (i.e. flap setting etc) is the same. This is why an AoA gauge is so useful for carrier-borne aircraft who probably have an approach speed nearer the stall than other aircraft. In the F4 Phantom we used to approach at approx. 1.18 times the stall speed ( as opposed to 1.3 Vs) and we used the AoA to give the correct margin above the stall. If you use the same AoA on the approach, you will have a higher approach speed at a higher weight and vice versa. You therefore do not have to calculate your weight to give a correct speed, you fly the correct AoA on the approach,as stipulated in the Flight Manual. This will give you a higher approach speed at heavy weights and a slower speed at lighter weights. regards to all John Richardson Tri-gear G-BXGG (not built by me), 912S. ________________________________ Message 5 _____________________________________ Time: 04:59:32 AM PST US From: Jim Brown Subject: Re: Europa-List: Angle of Attack --> Europa-List message posted by: Jim Brown Dave I also have the XS, and I agree with you about the long tail wheel arm. I also make my landings with the far end of the runway in my sight picture. I keep the same distance from top of the cowl to end of the runway until wheel touches runway. To get this sight picture, set on the end of the runway and and look at the other end. The sight picture is the distance the end of the runway is above the top of the cowl. This will set your angle of attack to land. I usually transition to the sight picture as I approach the threshold.

You ned to make sure they dont interfere with the fitting of the instrument module. The main problem is that they blow cold air onto your knees rather than on to your face. Many builders (me included) make up some form of duct to redirect the air away from the knees. If you go thro' the archives you will see that the flap often detaches from the adjusting screw in use. Making a more robust join at this point is a worthwhile mod before you fit them to the fuselage. Most spray paint is acrylic and will adhere Ok with good surface prep and an acrylic primer. Hope this helps.

I agree with all the knowledgeable comments as to its value. I particularly like the aural warning - it could well save your life one day when you're distracted. However I still use the ASI on short final. Whether this is because of the display, or the fact that I'm a luddite and can't move with the times, I don't know. I find you are well aware of the A/Cs weight and adjust the speed accordingly. As others have said the variables in the flare are literally infinite, so it is not surprising you have to adapt to the conditions. I'm sure nobody produces the 'perfect 10 ' every time. As to avoiding the dreaded bounce, I try to be as accurate as possible with the approach speed and land tail wheel first. This pitches the A/C nose down, reducing the AoA and cutting the lift, so the plane wants to stay on the ground. If you land hard on the main wheel the opposite occurs - the nose pitches up. lift increases and the A/C goes flying again. However I do agree that if you land on the tail wheel there is an issue with forward visibility- especially if, like me, you are vertically challenged.

Am I way off base or is the landing and take off characteristic in these aircraft that much different, so far as the mono-wheel characteristics or very similar. Hello Steve, My Europa experience is minimal (almost non existent) but I have spent considerable time in the back of a Blanik L-13. I think it would be a bit risky to assume the handling characteristics of the Europa might be like the Blanik. Firstly, the sailplane doesn't have an engine with its corresponding torque, gyroscopic and other effects. Also, the Blanik has almost twice the wing span of the Europa and is a lot longer. These attributes contribute greatly to the stability and ease of balancing on the ground. In a nose on breeze of about 10 kts, it is very easy to balance the Blanik owing to the long moment arm of the ailerons. (my kids used to love doing this when conditions permitted thinking they were "flying" ) Likewise, the longer fuselage gives the huge rudder on the Blanik very good directional control and even though many students have trouble at first steering on the ground, once the basics are mastered, it really is easy to steer and keep the wings off the ground until completely stopped, even with a moderate cross wind. I expect the Europa to be much more lively with its much shorter moment arms and C of G further behind the main wheel. > And the Blanik only has a 10kt crosswind limitation. I'm sure you will gain the skills to handle considerably more than a 10 kt crosswind in the Blanik Steve. > And one really fun piece of this training is speed brakes. Yes they are a revelation aren't they? As any power pilot discovers when he/she tries gliding, the airbrakes are akin to the throttle in a powered aircraft. I.e.. Airbrakes away = power on, out = power off. However, the effect of airbrakes is immediate whereas with a change of power, the effect is not. The effect of airbrakes is also much more pronounced. > Having never flown an aircraft with speed brakes, these are great, you can almost hang it on final approach with a steep angle. You certainly can and in fact the Blanik airbrakes are speed limiting which means you can dive vertically at the ground without exceeding VNE. There is NO EXCUSE for anyone who overshoots a landing in a Blanik or most sailplanes for that matter. Every student of mine had to prove to me that he /she could come over the fence at 1000 ft and be stopped on the ground within the first 1/3 of the strip. A bit daunting at first but a very good exercise nevertheless. Don't think I will attempt this in the Europa or at least if I did try it, I wouldn't expect the outcome to be successful ! > Lots of fun. I believe this experience will make me a much better Europa pilot so far as balancing on this basketball/wheel and ground handling. Indeed, it will make you a better pilot all round. Any gliding experience is no burden to carry. Just consider for a start all the forced landing practices you get ! Piece of cake mate, keep up the good work and nice to know you are enjoying the experience. Sorry for rambling on.

Jammed it there between other pipes and reconnected after a filter clean. Total fuel loss about 1 teaspoonful ( into some cheesecloth under the filters). You have to be quickish!! Easy.

The advantages would be tremendous and would virtually nullify the landing Aoa problems that have been the subject of recent discussion. Any pure jet aircraft performs best at high level and therefore stays up there as along as possible, hence the need for a quick descent at the end of a sortie. Airbrakes are essential and I used them for years for this purpose. Advantages - much shorter and easier landings. Quick descents. Ability to make a good landing from a too high approach. Ability to land over high obstacles. etc - there must be more! Disadvantages ... Nil.

With that said, the more different types of aircraft you can fly (including sailplanes) the better off you are, it all adds to the skill reptiore. I test flew my Europa without the benefit of a lot of transition time in type and I found it a great benefit to fly many different tailwheel aircraft as I could prior to my test flight. I must admit to be disappointed in finding the Europa isn't a very good glider, I was hoping with its sleek lines it would be. I guess that was to be expected with a high wing loading.

I have to fly into busy class C airports some times and I had to change my approach techniques. The tower guys we getting driven crazy because I would come clipping into their airspace at 140 knots and then be sitting on final at 55~60 knots. They would then end up with a pile of commuter jets piling up behind me and everyone was getting cranky. Now what I do (assuming the turbocharger isn't spun up and hot) is run slide down final on the high side and at around 100 knots, then when I am on short final I flatten the prop, slow it up to 80 ~ 85 knots and drop the gear. With the power off it will drop like a man hole cover, at half a mile out I can pull it up to 55~60 and everyone is happy. My local airport is towered, class D, and it is mostly GA traffic so I can come into the pattern in a more gentlemanly manner.

Based on Andy Draper's advice I made my operating limitation to be a MAW that would ensure that the aircraft could only perform aerobatics solo, and I added a tighter tolerance for the forward and aft C o G's. I excluded maneuvers that had a negative G component, along with anything that had a tail slide. Now with all that said, the limitations I added weren't based off any structural calculations, it was from my informal discussions with Andy. Since I have flying all I ever do is rolls, loops and the occasional spin. I'd like to do more but I need to find an instructor to teach me.

I guess that was to be expected with a high wing loading. Good-day Paul, I suspect the glide angle is affected more by your propeller than the wing loading. High performance sailplanes carry heaps of water ballast for the very purpose of increasing wing loading. The increased wing loading improves the gliding speed whilst not adversely affecting glide angle. IOW, can glide faster at the same glide angle. Makes an incredible difference in performance but in keeping with the principle of 'no such thing as a free lunch', climb rates are reduced but overall cross country speeds are higher. Have you tried stopping the engine completely to see how much the glide angle is improved ? Yes I'm serious. I think you will find it quite a bit better even unfeathered. Best regards Kingsley
