My first Solo flight

By April 1993, David Leong, Rick and myself had switched from flying the ‘Sky-walker’ to a dual-seat micro-light MxII at Tanjong Laboh. I had bought it from Perlis and had it trucked down to us at Batu Pahat. At this stage I have had some 13 hrs of flying and felt confident enough to go solo. I then informed my instructor Mr. Tay about my readiness and he later happily fixed the date of my solo to the 15th of May for early morning  which normally would be calm.

On the 14th night, I was high with excitement and tried to retire to  bead early but could not sleep. I felt restless, tossing about in bed, even tried counting ‘sheep’ but it did not work. It was probably a long while after midnight that I finally fell asleep. A loud crow from neighbour’s roaster was my morning call; I awoke.and proceeded to the airfield.

 

I opened the hanger-doors, rolled out my green MxII and indulged in a thorough ‘Pre-flight Checks’; an aviation ritual to ensure safety is complied. The MxII a 2-place, side-by-side seating with the student in the left-seat and the instructor in the right. This micro-light is suitable for beginners; slow and very forgiving which means that if you did a mistake, there would be ample time to correct it. It was designed and built for idiots like me to learn to fly. Only one control-stick shared by the two, student and instructor and has it’s advantage. The instructor can smack off the hands of the student pilot should he fumbles or simply freezes. The maximum speed of the MxII about 45mph and cruising at 36mph. At that time speed was not a concern as we were not going anywhere in a hurry. We were merely  enjoying flying around the circuit. Our air-speed indicator was a simple transparent plastic-tube with a spindle inside that has a wheel. there is an inlet at the bottom that channel the air into the tube and pushed the wheel up-wards. You read out the speed on the marked indicator printed on the tube.   

That morning I did some practices known as ‘crow-hops’ that is you lift off from one end of the runway and puts her down by the other end; just to loosen up the tension before the instructor appeared. When Mr Tay arrived I was ready, my MxII has been top-up with fuel; so I carried out my ‘Pre-flight checks before him. Walking around the micro-light making assessment, eyeing for loose bolts/nuts, cracks, dents on tubes, correct pressure or cuts on tyres and torn fabrics.

Having completed my walk around, Mr Tay was satisfied and we settled down to our seats and buckled-up. I did my cock-pit checks, control stick free movement, fuel-on and observed all clear before starting-up. I shouted out “clear props’ and manually pull the starter-cord just above our heads. The small Rotex engine roared noisily to life. I started to taxi slowly, heading for the runway in use; threshold #33 that means taking-off inland towards the coconut plantation. A final look around to confirm all clear, I pushed the throttle forward and the MxII started to race down gathering speed as it accelerated; in a moment it gathered enough momentum and lifted off the ground. We were airborne!

I held the control stick back for the best angle of climb, remembering Tay’s advise that gaining height is like putting money in the bank. In the event of an emergency you would have sufficient height and time to glide her down safely. I did a left bank into cross-wind, still climbing to circuit level of 200 ft. Another left bank took me to down-wind leg, easing the stick for straight and level flight; flying parallel to the runway.Overflying Jon’s hanger, heading for the cape, a hilly part of land jutting out to sea. The top of the hill is densely forested but the foot barren and rocky. A broken down ‘kelong’ (fishing-hut built on wooden-stake); 2 rows of stakes ‘fork’ out to lure the school of fish into the enclosure where a net is set to trap them.

.

Passing it I bank left again into base-leg heading for the island which is my landmark. We are doing a left-hand circuit which was our standard practice. Yet another left bank which brought us into our ‘final’ leg. The runway in sight, so line-up for the centre-line which is between the boundary red/white/red markers on either side of the runway. I reduce speed to descend gradually, aiming for the threshold #33; Coming in flying low over the oil-palms and by then you realise that the ground rushing pass before you,. So nose up gently and felt the under-carriage wheels touch the ground and roll along. Slowing down and taxing to my left, thus vacating the runway.

When I stopped Tay got out of his seat, gave a tap on my shoulder and beckoned me to go on my own. I was terribly excited as I nodded my head in acknowledgment. I took a deep breath, said a short prayer before shoving the throttle to full power. The tiny Rotex engine screaming angrily in protest as the MxII surged forward forcefully. The ground run became shorter as it was lighter with the absence of my instructor. I was nervous as I realised that the seat next to me empty; means that my guardian angel is not with me.  My heart beat kept pounding louder and faster and my fear factor shot up a few notches higher. I began recollect all that was drummed into me by Tay during training; about flight maneevers, effects of control,  power-management, and so on. My cross-wind leg was a bit shaky and down-wind even worst; I was trembling and as cold as ice. However I managed to keep ‘straight & level’ flight and parallel.to the runway; meanwhile focus on threshold #33. I had the whole sky to myself as no one else was flying.

Exhilirating!

Experiencing the exhilarating feelings of open-cock-pit flight

To slow down I bled some power for descending and took her in a graceful glide down into base-leg and into ‘Finals’.The flight path took me over the oil-palms before the runway proper appeared. My aim-point to touch down at the threshold. And the same sensation engulfed me, the ground rushing before me injecting fear into my system. Keeping calm, steady, steady, level up for the flare, that is nose-up, bled off a bit more power and the main under-carriage touched mother-earth with a slight bump. As she rolled out I immediately vacated the runway by pulling her aside. And as the engine coughed out to a stop, the was silence and a great sense of relief overcame me. For a moment I just sat there motionlessly and looking dumb; almost un-believable, I had done it. It had been a wonderful experience, filled with excitement, with fright, joy, a day to remember. My long waited childhood dreams of flying have been fulfilled and there was this complete sense of achievement and satisfaction within..

Micro-light, what is it?

The first time I saw a micro-light if not mistaken was in 1984 at the Air Show held at Changi Airport. It was at the old section where the Upper Changi Road cuts across the taxi-way that leads to the parking bay; there was crossing-barriers to regulate flow of traffic. Also the RAF had their Control-tower at this cross-section, I was walking around with my son looking at static display when we came across a row of strange and ugly looking flying machines. Strongly urged by curiosity we went to have a closer look and discovered with a shocking effect that the construction was of aluminium tubes. It took the form of a skeletal frame built around a buggy as the fuselage and had high wings. It was like going back to the time of the Wright Brothers, who built the ‘flyer’ at Kitty Hawk in 1903.

The Mx II are manufactured by Quicksilver (USA), the buggy has an “A” frame and down-tubes that supported the root-tube above to which the wings were connected. A king-post affixed at the top of the root-tube held the wings in position by the upper wires when it is on the ground. The under-surface of the wings ran the lower wires also known as the “flying wires” and are secured to the buggy. It held the wings in flight. An under-slung 6-gallon fuel tank fixed at the forward part of the root-tube and the other end held a small two-stroke inverted engine driving a 2 bladed wooden propeller. There were two upper-booms protruding from the wing’s trailing edge, one each from port/starboard side. Together with two lower-booms port/starboard sides from the buggy supported the whole tail-plane.

The skin covering the surface of the wings and the tail-plane were of multi-coloured durable synthetic fabric used same as in sailplane or sailing boats. The seating arrangements two seated side-by-side. It had a “tricycle undercarriage” that is two main wheels and a nose-wheel in front. What shocked me was the total absence of the floor-board in the cockpit, the wrap-around front wind shield/screen and windows. It was completely naked so as to say, the absence of what I would consider normal expectation of a cockpit. It was truly bare essential, without frills and just basic.

To me it seems life-threatening and scary enough for you are practically flying by the seat of your pants. In the open-cockpit concept the wind would be blowing or beating your face as you sit there fully exposed to the mercy of the elements. For a while I just stood there wondering, my small brain went into a long search of understanding. It seems ridiculous and definitely not my idea of flying, with legs that could dangle in mid-air and the wind blasting your face to numbness.

My question was is it a circus plane purposely built for the clown to fool around entertaining the crowd or simply for the brave-hearted and stupid. The irony was that it did not occur to me at that time that I would one day end up flying it. Only much later did I realized the full potential of this simple flying machine and the impact that it would have on recreation or fun flying. By it’s simplicity in construction, the maintenance is kept low by comparison to that of General Aviation. Obviously it makes micro-light flying more appealing and affordable to the ordinary man in the street with a shoe-string budget. It is an opportunity for those seeking air adventure especially the youth to take up the challenge and soar into the skies. In order to experience the exhilarating feelings of being in flight like a bird or nearest to it. At the same time to enjoy a bird’s eye view of the scenic surroundings; this time in looking down instead of the normal norm of looking upwards from the ground. The blue skies and the white fluffy clouds floating around as far as the eye can see; the wonders of creation.

Today advance technology has a great influence in the micro-light industry with better material, design and performance. New models with up-rated engines could fly faster, further and safer. Some daring and adventurous pilots have flown practically around the world. Generally to-day micro-light have been proven beyond reasonable doubts to be reliable; it could fly to distant places. You can call what you may a recreation, sports or fun flying; it is a challenge more exciting and demanding than any other. However it also carries an intoxicating effect; you get one shot in the air and you will be back for another.

Another micro-light type called the ‘Flight Star’ employed the same principle, skeletal frame, high-wing and tri-cycle undercarriage. However the wing-root extended further to the front where a traction-engine is positioned. The cockpit was protected by a large windshield mounted end of the nose section.

In Malaysia, the definition for a micro-light by the Department of Civil Aviation is as follows:-

a) Empty weight must not exceed 150 kg

b) Wing loading factor at maximum must not exceed 10 kg per square meter.

c) Seating capacity restricted to 2 persons including the pilot.

The EAA 1090 is a chapter in Malaysia under Capt. Siva who is the President with office in Kuala Lumpur. He undertakes the task of promoting and encouraging people especially the youth to participate and be part of the aviation community.

EAA means “Experimental Aircraft Association “ an organization founded in America

in 1953 to promote flying for it’s future generation. It has chapters Global catering for the enthusiasts in the fast expanding world of aviation,.

In the States the Association stage the greatest air show on earth at a place called “Oshkosh” a Mecca for the aviation lunatics like us. Some more than 12,000 aircraft of various categories assemble for the “Show”. The pilots have their opportunity to display their skill and bravado to thrill the fanatical crowd of thousands. Just imagine what a nightmare for the organizers and especially the air traffic controllers as numerous aircraft of all descriptions converge to this particular ‘hot spot’. For some of us flying had been our childhood dreams, each time we hear the sound of aircraft engine we would automatically look up to the sky. We are attracted by sight and sound; eager to know what type of aircraft, civilian or military, fighter or non-combatant. So when the opportunity did presented itself, we took the advantage to make our dreams come true.
