Dry White Spots On Dogs Noses

My first flight Ultralight

"[...] the wind in your face, see the whole glass down there without a vacuum that separates you is an immense sensation "

so far, and except for the biplane Bücker, everything that had flown aircraft cabin were closed. The ultralight always caught my attention, perhaps because I am one of those nostalgic pilots who enjoy flying "real" or maybe because I simply I would like to fly and even a broom.
Thanks to some friends back onto the Tango could have two axles and try the wonders of this new aviation unknown to me. Technically always considered the ultralights as "inferior" to the flight of the aircraft misnamed. Nothing is further from the truth. I do not mean to be difficult to fly, but it's another world in some technical aspects that need to change the chip.

As you can see from the photo, the cabin of Tango is not a luxury, but not deceived, if you take away the skin to a general aviation unit will see the same thing. I am struck to see the tires Fuel coming out of the bottles subject to the tubes that make up the carrier. Is narrow but quite comfortable, with seats angled slightly backward, equipped with shoulder harnesses and waist. The carrier is fairing on the front and open at the sides. The instrumentation is quite simple, an anemometer in km / h, an altimeter in meters, tachometers, fuel gauges, switches cut two magnets and a button that activates the starter motor. The controls are duplicated, along with power control. The brake is operated from the hand of the commander.
The launch is quieter than I expected, even I have to say that the wind of the propeller just upset despite having fairly close to us in the top front of the wing. The shooting is just like a normal plane, ie with the pedals. However, the tango has a different characteristic to the other aircraft I've flown, is two axes, ie, has no wings. The warping is done using the rudder, which is moved by the lever as if it were the normal roll control. It is just this point where the pilot used to flying three-axis aircraft have to change the chip. Put the right foot at takeoff to compensate for torque effect is useless. In Tango, your feet become your hands. And do not believe that it is simple catch it at first, especially in the shots.

align at the top, do a quick check of instruments and a briefing. I put the engine at 6,000 rpm and rushed through the grass track Fervenza. John, my instructor, pull the lever and go to air. I admit I slept on my first takeoff, used to other aircraft in which one is checking the engine and speed, in a microlight happens very fast. You put power and in just 4 seconds and you're in the air. Now I try to maintain 80km / h during the climb, but my eyes are inevitably out. How wonderful! It is complicated to explain what you feel the wind in your face, see everything down there without a glass separates you from the vacuum is a great feeling. I have to say that fly over the Fervenza Reservoir is gorgeous with all those islands in the middle. Juan beckons me to reduce to 5,000 rpm and turn over the lake. I look back on my right and see the wing pointing downward, the sensation of vertigo is void, even given the impression that you're going to fall into the void.
Juan instructs me to do traffic circuit and takes off. After a couple of turns and I'm doing with the Tango. Short at 4,000 rpm and start holding down the 80km / h the anemometer. Viro to end at a height that seems more or less adequate. However, the Tango has a glide slope somewhat steeper than normal sport aviation aircraft. Plans, and take on a very small space, but does not travel horizontally as well as other aircraft. I adjusted the alignment to the engine and the speed with the elevator, always at 80km / h. The Tango is very low, you could say that you take your ass land almost flat on the floor, and references are deceiving. Think you're going to take and you're still a tad high when you pull the lever. Me under a balloon in the head, although not very pronounced, we have plenty of speed so a little peak and return to pull gently. John was assisting in the making, because here's another great difficulty, used to correct the runway with the pedals, I did not realize that the nose wheel is still in the air and has no effect on the ground. John pushes the lever forward to touch the door, and I, in the midst of a smile not to have realized that stupid detail, correct shaft, and once stabilized, I put in power again. Four seconds and the ground is down there again. It's amazing how little space that runs to take off.


The second circuit and was much better, although I am so impressed by the sense of "free flight" which gives a apparatus of this type do not go yet before the plane as I wish. The approach was much more stabilized than the first and making quite soft, this time without balloons. John applies brakes and go to the apron. But how?! That's it?! No doubt the 20 minutes that I should be up there I missed a few seconds.
In short, it looks like the stunt in one respect: once you try two things can happen, or reject it completely, or engages you while you do not stop until you try it again. Although very limited equipment and perhaps the aesthetic aspect is not very attractive, the sensation of flying outdoor offering is indescribable. Yes ... always with great head, because despite the appearance of "toy", they are not at all.

I hope soon to tell more stories "of tubing and fabric."

Replacement Light For Outdoor Santa

Mach 1, The Sound Barrier

In the high desert of Mojave there is nothing but dust, fossils, petrified cactus branches, sand storms that cross the air to 42 degrees. In winter, the rains are some pools that appear faint in the curved worms, shrimp-like. Gulls come from the ocean to devour. The Mojave looks like a landscape of ancient geological era. Also is the best runway in the world. In March, any remaining moisture evaporates and vastness that takes a firm surface and polished.
Sixty years ago, two small sheds, a gas station and the canteen of a tanned woman wearing the paradoxical name of Pancho Barnes, formed Muroc Air Base. The pilots had a salary of $ 283 per month and living in bungalows with wire mesh doors battered by freezing winds that night.
The base offered refuge to the test drivers. The aircraft was then a rustic pioneer company and the new invention, a junk lot simple. The X-1 was very small and thin wings, the ship followed the contours of a .50, but looked more like a sausage compact, and the door was identical to the openings to the dogs in the webs of wire. The X-1 was designed to achieve the speed known as Mach 1 (in honor of Ernst Mach sonic research), ie, to break the sound barrier . Some physicists thought that the barrier was a real physical limit and that nothing would come out unscathed from the impact sound. In 1946, Geoffrey de Havilland, son of the famous aeronautical engineer, tried to make the DH 108 was designed by his father arrived Mach 1. The plane and pilot were disintegrated in the attempt. `` The sound barrier was that you could buy a ranch in the sky,''Tom Wolfe wrote in an exceptional non-fiction novel The Right Stuff .
designated driver to crew the X-1 was Slick Goodlin, a cold-blooded man who asked for $ 150 000 out shot the lapis sky. Muroc base was barely money for fuel and eyes turned to a man without imagination to the danger, who spoke broken English and archaic of the Appalachian Mountains and at 18 had changed the overalls by driller uniform pilot: Chuck Yeager.
Sixty years after his suicide flight, Yeager is still unable to see them as little bias as epic. `` Somebody had to do the job,''said before the television interviewers perplexed hope the retired general, who at 74 years continues to fly for pleasure, unravel the mystery of heroism.
Yeager is a kind of magnificent air plumber. Find holes, clean the area, draws an evacuation route. Their responses are those of a craftsman able to see that is about all turns to shit.
At 22, Chuck Yeager participated in the second World War, was wounded in combat and shot down 13 aircraft. At age 24, was ready to fly towards its own annihilation. The only problem is that there was no way to stop it. In its first flights with the X-1 reached Mach 0.9 and 0 0 85 without permission from the base. The final flight was ahead for Tuesday October 14, 1947.
Sunday Yeager got drunk as usual in the canteen of Pancho Barnes and climbed on a horse to graze armadillos in the light of the moon. Fell somewhere in the desert and broke two ribs.
on Tuesday was in the cabin of the X-1, smearing shampoo on board controls to prevent freezing in height, with two broken ribs and a parachute which only served as a mattress. It was hard to reach the door and took a broom to help. Under these conditions up to the sky and produced the sound of which was the first out. `` When the speed reached Mach 1.05-Tom Wolfe writes, "Yeager had the sensation of exceeding the ceiling of the sky. The air took on a deep purple hue and all the stars and the moon came out suddenly, and the sun shone at the same time. Had reached a layer of the upper atmosphere where the air is too thin to contain reflective particles. I was just watching the space. The X-1 approached the top of His ascension and we had seven minutes ... Paradise Flyer. Was faster than any other man in history, everything was almost silent up there, he had exhausted his supply of fuel and was so high in a space so vast that there was little notion of movement. He was master of the sky. It was the loneliness of a king, unique and inviolable, the dome of the world. It would take seven minutes to redirect the path and go down to Muroc.''
Fifty years later, Chuck Yeager, described the scene as if it had never taken off and Tom Wolfe as though it never landed. In the third rock from the sun, the sky is still a mysterious barrier.

Brent Corrigan Y Brent Everett School



The reason for this post is none other than my surprise at a report by BBC1 aired yesterday in which they recreated the crash of an ultralight pilot. The unit became lost and the pilot was unable to recover the plane. He later described his attempted recovery maneuver as "put the engine at full power and pulled the lever." I would put this as an example of what NOT to do ever.



For those who are not clear what this is going to explain what it means to "stall." The loss, which refers to the loss of lift or "stall" English is a phenomenon that occurs in the aircraft when the wing exceeds a certain angle (called the attack) and stop the air flow through it properly, forming a turbulence on the upper surface of the wing, making it less the lift force that keeps it in the air, the consequence is that the plane stops flying and falls.



The stalling often occur especially in tight turns at low speed. This is because when the plane veered submit to a centrifugal force that increases the weight of it. To compensate for this we need to increase weight gain by increasing lift speed, thus reducing the angle of attack. Otherwise, the wings could not withstand the weight of the aircraft and it would fall.



If you were to produce a stall there is a principle of action common to all aircraft in the world, big, small etc. This principle of action is none other than to cut power and focus controls. Cut power when the plane falls may seem a contradiction, however nothing is further from the truth. The aircraft, especially those having a single engine gyroscopic effect caused by the movement of the propeller, causing the plane tends to turn on itself to the opposite side in which the propeller rotates. This effect is greater the more power you apply it to the engine. The unadjusted stall the plane takes time to fall "curling" on itself in a spiral, is called spin. Adding power thinking it will save us, all you get is to increase the gyroscopic effect and thus further accuse the spiral, making it practically impossible to recover the plane. Therefore it is necessary to cut all the engine power to nullify that effect.



The other point is to focus the controls. During a loss we will run out of aileron control, as we have said that the loss occurs because the air does not flow properly through the wing, so the effect of the ailerons is zero. However, it is necessary to focus the controls to ensure they are not pulling the lever and the other surfaces are kept in the aero position. Pull the lever means increasing the angle of attack, so we'll be getting the plane loss continuously.



Following these two steps, stop rotating the plane only. How long this takes depends on the stability of the aircraft. If it is an unstable aircraft like a fighter or a stunt plane, we may need to use the opposite foot to stop rotation before.



After stopping the rotation and have resolved much of the problem. But we have one that is leveling the plane again, and this is where many pilots were killed. If we have entered into a spin is very likely that we stopped the rotation with the plane inverted. Perhaps the rush to see again the horizon level do we make the huge mistake to pull the lever to raise. This should never be done. After stopping the rotation, the first thing to do is look out. If you're upside down is much easier to implement spoiler and make a half roll, and then pull to level always making sure we have enough speed and not will put the plane and another loss could be fatal. And finally, will put new engine.



We conclude therefore that the engine is the enemy number one for loss, and therefore the first thing to remove. Then the focus control to avoid putting the aircraft follow a loss. And finally, always look out, first with wing level and then the elevator, never backward. Well done, is a maneuver that lasts no more than 5 seconds.



However, we know very well that it is necessary to have another key factor in our favor

Gay Cruising Techniques

Loss Vigo Airshow 2008





Festival Vigo air is now undoubtedly one of the most important aviation events worldwide. Not only known for its coastal location, right on the beach, but for its great variety, organization and number of visitors.

The 2008 edition again surprised. More than 200,000 people gathered on the beach at Samil from 9.30 am to enjoy the performances of classics such as air Piper Colt, the Chipmunk and Stearman who inaugurated the conference.



After them came the Yakovlev aerobatic team of 52 Milano, and Castor Fantoba with Sukhoi to put us all goose bumps with their spectacular maneuvers in the sky. A ship invades the exhibition area and immediately see the helicopter Fishing 1 to get a demonstration of rescue at sea where it became clear the vast expertise and coordination of the entire crew of Pesca 1.



Without giving demonstrations on the sea, a CL-415 43 Group of fire showed up on the beach of Samil for what was undoubtedly one of the best shows throughout the festival. The crowd stood amazed at the maneuverability of the CL-415, not only in air but also in the ditching operations, loading and discharge of water into the sea, demonstrating the great capacity of this aircraft for this type of work.



Turning now to the group of the festival, two A-10 from Germany flew overhead, along with an F-18 Hornet the English Army and a Eurofighter . And this year's premiere, the jewel of the festival, a B1 bomber !. No doubt a real treat for our eyes and they seldom have the opportunity to see a B1 flying ahead of us.



also starred in this block Culebra Patrol with Fantoba and Verlarde as actors, beautiful drawing in the sky, and the always spectacular patrols " handles" and Rotors with Portugal Allouette and ASPA, the helicopter aerobatic team of the English Air Force.



And since not everything could be wings in this festival, the sky fell Paragliders group Air Force and Patrol PAPEA ALAS. Highlighting the great skill shown by these great professional divers who had to face a very windy day, which did not prevent nail all their maneuvers.



To close the festival, once again, as always spectacular, the Eagle Patrol . A perfect performance of this patrol as usual people rose from their seats. Surely a 10 for these professionals, who for nearly half an hour we were speechless, without "dead time" between maneuvers and speaker narrates a very clear and precise.



And finally, from here I send a big hug to the organization of the festival and all the staff for their efficient and orderly work, at the height of an international festival, because we are well aware that such events will not performed alone and needed the work of a year so that everything goes as expected. No doubt the Vigo Airshow is a great example to follow, not only nationally but also internationally.
