G'day!

G'day

G'day! and welcome to my blog's new home. I'd like to say a big 'cheers mate' to Clay for building me such a fabulous new house.

Here you will find my articles and blogs from the sky documenting my aerial adventure across Australia, and sometimes - when I'm very lucky - around the world!

Lots of airyplanes, plenty of new shoes and hopefully many undiscovered places.


Blue skies,

I Glid, I Did




Clunk! That’s both the sound of the tug rope leaving the glider and the sound of your brain realizing you’re up at 2000ft without an engine. In that moment, a powered pilot must own and acknowledge that they’re going to have to land without the energy of an engine.

There are no second chances at landing a glider, a fact all too blatant to Captain Bob Pearson, pilot of Air Canada flight 143, the Boeing 767 that lost both engines due to fuel starvation, and became the Gimli Glider (www.damninteresting.com/the-gimli-glider/#continue).  Captain Pearson’s near-perfect dead-stick flying, and the skills he utilised in landing the powerless jet serve as the definitive demonstration, for every pilot, of the value of gliding experience.

In an attempt to understand these skills first hand, I was invited by glider pilot Leonie Furze to the Bathurst Soaring Club, based at Piper’s Field, just to the north-west of Bathurst (http://bathurstsoaring.org.au/default.asp). Myself a powered-pilot with around 600 hours, I asked Leonie how she expected my glide experience to differ from a ‘normal’ powered flight. “The most interesting thing about gliding,” Leonie explained, “is that every flight is different. In order to succeed as a glider pilot, you have to harness so many things: your understanding of the weather becomes critical; you become an expert in energy management; you spend so much time looking outside, always assessing the options for landing. You’re critically aware of your altitude, your surroundings, your attitude relative to the horizon at all times. You won’t believe the way it extends your skill set as a pilot.”



“I’m often asked by powered pilots, ‘How long before I can solo a glider, as I already know how to fly?’” commented instructor Nick Wills. “My standard (tongue in cheek) reply is “slightly longer than if we picked a random person off the street!” As an instructor in gliding and powered flight, Nick extolled the benefits of gliding experience. “I cannot recommend it highly enough,” he said “The advantages are enormous: a glider pilot must fly accurately and efficiently, being in balance at all times, because energy management is critical. Adverse yaw in turns needs precise coordination of stick and rudder - those pedals are not footrests! You learn to gauge height and distance (glide angles) with instinctive accuracy at all times during all phases of flight –you don’t have an engine dragging you through the sky – so you are constantly looking for options to land safely. When you do land, you have got one chance and one chance only.  There is no going around! What do you call a Cessna 172 when the engine quits?  Answer: a glider (although not a very good one!) In addition, the GFA require full spin recovery checks for all pilots once per year (in my opinion, this should be a requirement for any pilot who flies an aircraft capable of spinning –which is most of them).”

Graham Brown



Keen to experience these benefits myself, I’m introduced to my instructor for this session, Graham Brown - a glider pilot with over 40 years experience - and my long-winged bird, a sleek looking ASK 21, a glass-reinforced plastic two-seater mid-wing glider with a T-tail.

Touchy Feely – fly by senses, not just by instruments

Aside from the enormous wings, which boast a glide ratio of 36:1, the obvious difference between a glider and a powered aircraft is in the cockpit instrumentation: there’s barely any in a glider. An ASI, AI, compass and the glider’s unique instrument, the variometer, which used to determine rising or sinking air, are the main instruments in the ASK 21. But, as Graham is about to demonstrate, a competent and experienced glider pilot can manage without any of them. “Gliding is very much about feeling the sensations of flight,” he explains. “Your attitude, along with the thermals, will determine your altitude. The sound of the wind will indicate your airspeed. You will feel, in your seat, whether you are climbing and descending. And, at this stage, you will know where you are in relation to the airfield, because we will not go far, and you’ll be able to see it.”  It’s a very tactile experience, one that emphasises why the senses of vision, hearing and balance are so important to a pilot.

As we hook up to the tug, Graham reveals the airbrakes which increase drag, reduce lift and are used to control the rate of decent during the approach to land. The ideal approach is a “half brake approach”. They can also be used to descend rapidly from altitude.
Graham’s safety briefing includes the tug release control (“please don’t touch that one” he comments, sardonically) and the trim, which sits alongside the stick. “No throttle!” I remark, pointlessly.

With the wind straight down the runway, we begin rolling and Graham demonstrates how to stay out of the tug’s slipstream by adopting a high or low position. At 2000ft, Graham asks me if I’m ready, and clunk, the tug banks to the left, we bank to the right and we’re soaring. I suffer an initial moment of panic before calm descends over me. Without an engine, the sounds are so different; you can hear only the wind and it becomes immediately clear that you are soaring; that you are experiencing flight’s most pure form. Graham shows me how to listen to the wind to judge our airspeed, and by changing attitude, we change the sound of the wind, first in the climb (quieter) and in the descent (when the wind howls). In this, I’ve learnt how, in a case of instrument failure, a glider pilot could be confident in landing the aircraft without the instrumentation on which a powered pilot is so dependent.



Fancy Footwork – learning (again) the importance of rudder

It’s a wonderful day for gliding, with plenty of cumulus clouds providing us our desired lift, and we experience no problem in climbing to 6000ft. Graham hands the ASK 21 over to me, and instructs me to turn, to climb, to descend and to have a ‘good feel’ of the controls. “One of the benefits of a glider is that it allows us to demonstrate adverse yaw,” explains Graham. “This is turn shows the importance of using the rudder in keeping the aircraft in balance,” he says, giving the right rudder a huge boot to demonstrate. 

These rudder skills are also vital in a non powered landing; without an engine to provide power close to the ground, and with a go-around a non-option, a glider pilot’s landing requires a great deal of rudder skill. I think back to the times I’ve relied only on power to rescue me from an ugly approach, and shudder.

Seeing is Believing – improve your situational awareness

The cockpit FLARM starts beeping, and I immediately look out for traffic, spying another glider heading our way. “It’s common for glider pilots to all head for the same cloud, invariably the best cloud,” Graham explains. “This is why situational awareness is paramount in glider operations.  Sighting and avoiding traffic is a critical skill.  You can’t assume other aircraft are also FLARM equipped.” Another hazard is birds, particularly eagles, who often confuse gliders for other birds. However, because there are so few cockpit instruments to monitor, it’s very natural to spend most of the time looking out, scanning for traffic and searching for clouds, like a surfer seeks waves.



Watch the Birdies – learn more about the weather

Curious to learn more, I ask Graham for clues. “ The birds give us a lot of information,” he tells me. “Have you ever seen a flock of pelicans circling high in the sky or a seagull hovering motionless over a headland? The pelicans are flying in a column of rising air (a thermal) and the seagull is flying in the rising air deflected upwards by the cliff face. In both cases the birds are in an air mass that is rising faster than they are descending through it. Gliders exploit exactly the same natural phenomenon.”

While knowledge of the weather is vital to all pilots, it’s paramount to gliders, particularly those participating in a cross-country. “On poor soaring days you will be restricted to within glide range of the airfield,” Graham says. “However on good days, once you are competent, you can attempt recognised flights of 50, 300, 500 or 1,000km. The straight glide performance of gliders varies immensely. A typical club glider will easily glide 10km for each 1,000 feet without encountering any rising air. You soon learn to spot the banks of cloud that facilitate long range gliding.”




Be Aware, Be Spatially Aware – and improve your judgment of height and distance

Typically gliders fly at around 70 - 100 knots between thermals. When circling in lift, the speed may be as little as 40 knots; gliding is all about energy management and this is best demonstrated in the approach and landing. While the wind whistles about us, we commence our descent to the field, and Graham demonstrates the importance of our height and distance from the strip as we fly a circuit. He deliberately overshoots on final to slip off a little height, but just as I remark that we seem terribly high, he deploys the air brakes. We sink like a stone. We aim for the latter part of the strip, to avoid turbulence from the hill. What happens if we undershoot? “We don’t,” answers Graham, with a laugh.

No Second Chances – learn advanced energy management

Short final in a glider is much like any other – we are certain to land on the nominated point.  However, what becomes clear to me (other than the clear absence of engine power), is that landing a glider is like landing a tail-dragger. Turns out all gliders are tail-draggers, which I discover when I ask what prevents us from taking off again, given our weight and the into-wind position we’re in. “We stall the aircraft onto the runway,” explains Graham. It’s another example of energy management: “we will run out of lift, and then bring the stick back to pin the tail down. Eventually, we’ll use up all the energy.”

And indeed we do, and I soon realise there’s no energy left to get us back to the hangar.



Smells like Team Spirit – join a culture of safety

As we wait for the pick up car, Graham details the fundamental importance of teamwork in gliding. “It’s not a solo sport; it takes a team to glide. Someone has to fly the tug, there’s someone at the wing to aid with the take-off, another person to collect you from the field. It’s a club sport, and with that comes a club spirit. We’re extremely sociable here; we have a clubhouse, and a series of caravans in which people come and spend the weekend. A lot of our pilots live in Sydney and spend the weekends up here. A benefit of the sociability of gliding is that it promotes airmanship and safety. We constantly discuss our experiences, and the old mentor the new. We encourage each other to share tips and tricks, and that breeds a culture of safety and respect.”

Upon arrival back at the club I’m introduced to club CFI Bob Hall, who is very keen to hear about my experience. I discover that gliding in Australia has one the best safety records in the world. Before long, Leonie and Nick are joining in and we’re discussing the many merits of gliding and the way in which it stretches your skills. As they kindly invite me to join the club, and to participate in their next social event, I can’t help but wonder if gliding not only makes you a better pilot, but whether it makes you a happier, more sociable person as well.

Huge thanks to Leonie Furze, Nick Wills, Bob Hall and Graham Brown

Passing the Stick...



Hot the on the heels of a week at Avalon, I barely had time to recover from the av-frenzy before it was my turn to tote the baton. My friend Andrew, owner of Banktown's finest C182, had offered to lend me his aircraft in honour of the relay and arrived at Essendon on the Sunday to hand over the controls (and the cushion!) 

Landing at Mallacoota

Having caught up with baton-wielder Peta Denham Harvey at Avalon, I knew the suspected the arrival at Mallacoota might be a little later than the projected 13.00, on account of the first leg being flown by four ladies, each stopping at a different port to hand over the marvellously hand-crafted wooden baton, and iPad provided by AvPlan.


The Vic girls arrive with the baton


Having landed at Mallacoota at lunchtime, just as the wind swung round to the gravel runway - 07 - I took the time to relax and enjoy a tour of the town, courtesy of local couple Peter and Wendy (who provided home made muffins). The Vic girls touched down at 16.30, shortly after the arrival of two Falcos from Merrimbula, piloted by Neil Bourke and Ian Newman.

After a whirlwind of photos, it was a race against the light to get to Merimbula, hand over the baton to Belinda Baulch on behalf of Jan Goodhew. After another round of media, and a wonderful welcoming committee (special thanks, as ever, to the Frogs Hollow Fliers for their generous donation) we took of and pointed the nose towards Bankstown. Weirdly, Nowra was still active, and even with a direct to Ulladulla, the elements won when I ran out of light near Wollongong. 

Handing the baton to Belinda in Merimbula

A VFR pilot without a current night rating is always prepared (a dollar for every time I've been caught short at YWOL due to wx!) and it was a no brainer to tie down the 182 and hop in a cab for a direct to Wollongong's Novotel. As I touched down on the blissful hotel bed, I was reminded that the finest bonus of flying a 182 is that I always have a spare pillow - feather at that - should I ever get stranded in a regional hotel.

Avalon International Airshow, 2015 - Voice-Breakingly Good!


 As the unofficial holder of the ‘talks under water’ award, it takes a lot to break my voice. I do demos for a living and my favourite pastime, aside from flying, is talking. I prefer controlled airspace to class G, largely because it gives me a greater chance to talk. So when I lost my voice on the last trade day of the Avalon Airshow, it was a certain sign of how busy the show had been for Team AvPlan.

The AvPlan Crew gets ready for Day One


Avalon 2015 was the most successful airshow yet for AvPlan EFB.  On the Tuesday, it was announced that we had won the Civil Industry National Innovation Award 2015. Bevan attended the ceremony, where the award (a glass boomerang) was presented by Air Marshal Les Fisher.

The AvPlan stand, in hall 2, began buzzing on Tuesday morning and didn’t stop. With the impending launch of version 5.0, pilots were lining up to see our new features, to offer feedback and (mostly) praise about AvPlan and to share their experiences of using the app. We had visitors from all over the country, including jet pilots; a ballonatic; a state senator who never flies without AvPlan; a Powerball winner ($20m! Can you imagine? He was visiting Avalon with ten mil to spend and popped by to say how much he loved AvPlan); and a myriad of pilots from the Army, Navy and RAAF.

Rochelle and Bevan


All five of us – six on Friday when Rochelle popped in to help out – were flatchat the whole show. Popular questions were around our upcoming iOS release, V5.0; our impending Android update, and the ever present ‘what’s the difference between you and the other EFBs’ (which is one of my personal favourites, as I love nothing more than demonstrating AvPlan’s Mega VFR maps, amazing weather radar overlay, velocity world weather and active airspace options – to name but a few).

On Wednesday, I handed over the AvPlan iPad to Peta Denham Harvey, who is the first pilot in the Women Pilots' Relay https://www.facebook.com/WomenPilotsRelay?ref=hl from Avalon to Launceston, counterclockwise. The relay has already raised over $7000 for cancer research, and AvPlan is proud to be a supporter.

After having met what seemed like every single one of our users – and lots of new users, too – I left on Friday, while the rest of the crew continued through til Sunday, enjoying the airshow and questions from the general public.

On behalf of the AvPlan team, I’d like to thank everyone who came by to offer their feedback, support and their congratulations on our winning of the award. 2015 is shaping up to be the best year yet for AvSoft Inc, and I’m delighted to be a part of it.
