The Warmth of Achievement

A trio of February flights in cold, clear, still weather. In fact there was no wind, perfect for the Eindecker but it would have been far too cold for the pilot…

Here’s the Sting using the power of the sun to warm up on the grass. Refuelling is by jerrycan but the aircraft has to be on the grass. Any spillages on the tarmac dissolve the stuff and are frowned upon. Because of this, we usually push the aircraft out of the hangar, then start the engine and taxi onto the grass. It also helps to warm the engine, making starting a lot easier when we actually do go flying.

Making our way down runway 09 to the grass runway 33. Normally at this time of year the grass runway is waterlogged and unusable, but with freezing temperatures after a dry spell it’s now just hard. Perfectly usable.

The Skydemon trace of the trip up to the hills:

The view north from the edge of the hills. There’s another aircraft somewhere in this picture. Click on the picture to view the big version and see if you can spot it…a head-to-head competition between both my readers!

Snow coverage was patchy. Here we are east of Kirriemuir. The industrial complex within the woods in the centre of the picture is what’s known in the trade as a GVS. It stands for gas venting station and this has an avoid area around it up to 2900 feet. On occasions the pipelines need to be vented for maintenance or cleaning and when they do a column of high pressure natural gas comes up into the atmosphere. It doesn’t happen very often but when it does you don’t want to be flying through the plume. Engines and humans don’t run very well when there’s no oxygen to breathe, so it’s best to keep away…

Winter flying is great. The aircraft and engine perform better in the cold air. By the time we got back to Perth the snow was mostly melted, apart from in the shadow of the hangar. The Tiger Moth was just going up for a jaunt – that must have been COLD. Not taking the Eindecker was a good decision.

Clear and dry the next day, with a bit more snow overnight. Time for a trip over Fife…


The trace of the flight: east from Perth around the north of Dundee with more snow on the ground…

The turning point at Monikie Reservoir was really hard to make out. It turns out that frozen water with snow on top looks just like a field from 4000 ft.

Snow on the Sidlaw hills:

Dundee from 4000ft:

Once into Fife there was a distinct line on the ground where the snow finished. No gentle change, one field had snow and the next was clear. This next wing view shows the former Naval Air Station at Crail on the tip of Fife. It was known as HMS Jackdaw, and is acknowledged as the best preserved abandoned military airfield in Scotland. You can still land there, but one of the old runways is now a drag racing strip.


By now we were down to 3500 ft, and with the power settings just right were getting 120 kts indicated air speed:

Once back at Perth it was starting to cloud over. The forecast for the next 48 hours was pretty dire, precluding any thought of aviating. My run of flying every day in February lasted for just two days.

I love putting the aircraft away in the hangar after a winter flight. The engine is still warm as you put the covers on. It’s a different type of warmth. Sure it’s just molecules vibrating at higher frequencies because they have more energy, but it feels totally different from putting your hand on a warm heater. The difference is that the heat is a slowly dissipating memory of when the engine was working, powering the aircraft through the sky, giving the occupants unique memories of their own, having defied gravity one more time. I call it “The warmth of achievement” – I quite like the term.

On the 5th the weather cleared enough for a quick trip round the local area:

And we even managed to get 125 knots, although looking at the Skydemon altitude trace above the speed might have had a little bit of a gravity assist – not defying gravity 100% but just like NASA, using the gravity well of a planet to add energy. Does that make me an astronaut? Space cadet more like.

125 knots is pretty good on 100 horsepower. But as we said after the Sweden trip more speed, more baggage space and an autopilot would be handy.

We have recently returned from Dublin where we looked at, inspected and flew such a machine. Which was for sale.

More news soon! Watch this space…

Making Sure The Tail Doesn’t Fall Off

If the tail falls off an aircraft in flight, it’s usually bad. It would not make for a very happy new year. It happened in the USA, to a Sting like ours. The whole horizontal stabiliser fell off and the aircraft ended up in a Florida field looking like this:

Pretty much wrecked, but the single occupant walked away. It probably would have been fatal if not for the built in parachute rescue system…

( Both crash photos courtesy of http://www.kathrynsreport.com/2018/11/tl-ultralight-sting-sport-n494n.html )

Because of this we had an Airworthiness Information Leaflet mandating an inspection of the horizontal stabiliser mounting pins within 5 flying hours and thereafter every year. Hearsay is that the mounting pins of the Florida crash aircraft were severely corroded.

Senior Engineer Brenda helped to remove the stab once the controls had been disconnected. Here she is peeling off silicone, the maintenance manual says the stab should be reattached in a bed of the stuff. It reduces vibration and helps keep the stab in place, but can be a real pain to remove once the tailplane is off the aircraft:

We also found a good use for our Nando’s card, it was great for gently scraping off the old silicone:

Our pins didn’t look corroded at all, nice and shiny. They passed the inspection and just needed a little polish and regreasing before reassembly:

Once inspected, the world’s coolest copilot helped with the reassembly (Thank you, Rory), and then I did battle with reconnecting the controls. Lots of fiddly washers in the elevator and trim control connections:

The connectors were reassembled “dry” with no grease, for ease of inspection, and then lubricated once inspected. Every critical system needs a duplicate inspection if it is disturbed; I do one as part of the reassembly process and Sandy my inspector does another, we both sign in the aircraft logbook.

Another reason for reassembling “dry” is that washers are very slippery and can ping off into the distance if given half a chance. Check the dark corners of any hangar and you’re bound to find one. Here’s the greased up final product:

Finally came the wire locking of the mounting bolt and reattachment of the fairing. I was having a hell of a time holding the torch while wire locking and eventually ended up taping it to the elevator control rod. If only I had thought of that earlier…

Aircraft inspected and reassembled, paperwork all in order and logbook signed up, it was time to go flying…

…and the engine wouldn’t start. The battery had been sitting in a (very) cold hangar for over a month and just wasn’t up to the job.

There are some awesome videos at “Sting Flight” on YouTube, see https://www.youtube.com/channel/UC0avm_9h4lpS5sIcQaBCQ_A – producer Rich DeHaven says that a battery lasts about 200 hours – ours has made it to 300 or so. It has done well but it’s about time for a change.

Luckily the battery in the Sting is a popular model, also used in quad bikes and snowmobiles, so it doesn’t have the big aviation markup normally associated with aircraft parts. A pleasant surprise to not pay through the nose for bits for the aircraft.

Just waiting for the new battery to arrive…the weather is lovely, and we’re stuck on the ground. Grrrrr.

First Snow!

Snow on the hills! And a day off with good weather, so time to try out the camera again – no iPhone pics this time, Canon EOS 1300D with 18-55 lens shooting at 18mm through the canopy at 1/320 in shutter priority. Just pointing and shooting and seeing what comes out…

This is taken from the edge of the hills looking south, with no snow in that direction:

Plenty of snow in the other direction

Cool cloud formations spilling over the peaks:

Looking up the A93 towards Glenshee Ski Centre:

Looking north towards the ski centre. The slopes on the east side of the road are called “Sunnyside” for some strange reason…

Still not enough snow for skiing, but it’s early yet. A good season on top of last year’s good season would be fantastic and would justify all the investment in new and refurbished lifts that the ski centre has put in over the last few years. It might also give us a bit of trade at work. Don’t want anybody to get hurt but it’s nice to be able to swoop in and take them to hospital when we can. It turns a 70 minute road journey by ambulance into a 20 minute flight. And the views are great…

Scared of Heights

Some repairs required on the hangar roof. Thousands of hours flying and it turns out I’m scared of heights:

Well, maybe not heights. Just the potential for falling with the sudden stop at the bottom. At least the view from up there was good, and the roof got fixed…

Kortrijk Update

Remember this?

Kortrijk is a sleepy little airfield. So sleepy that there is nobody to collect the landing fee…there’s a form to fill out and post in a box. Eventually they get around to sending a bill

We finally got the bill! Over two months later…

Autumn Flying Piccies

Just messing about with the iPhone camera. Normally we’ve been taking shots like the first one with a bit of sky in them…

…but I was solo this time, so I was able to get a bit more vigorous with bank angles to get the shot. Brenda does’t like it getting too “tilty”so this was a perfect opportunity to experiment. This is a fruit farm near Blairgowrie:

And the River Tay at Murthly:

Stubble burning just north of Forfar:

Glamis, the Queen Mother’s ancestral home:

And some more random smoke, location uncertain:

iPhone camera experimentation = thinly disguised excuse to go flying!

The Trip Home (3) – Racing The Rain

We woke in Kortrijk to wall-to-wall sunshine, but a look at the forecast for Scotland showed a band of rain moving in from the Atlantic. If we got a move on and didn’t get delayed too much then we should be fine for getting home.

After a hotel breakfast and checking out, we made our way to the airport. Past the drop-off area:

Following the signs to the impressively named “Food Court” –

There is a café/restaurant upstairs but it wasn’t open on either of our visits. The food court turns out to be a couple of vending machines:

While planning we met these Belgians who were off to Duxford for the day. The landing fee at Duxford gets you into the Imperial War Museum as well:

Routing sorted out and flight plan submitted, the friendly customs guys let us out to the aircraft. No need to refuel this time as last night’s hop from Midden Zeeland hadn’t used too much and Rochester is less than an hour from Kortrijk at our speeds. Thumbs-up from the co-pilot and we’re ready to go:

Climbing out towards Koksijde we could see in the far distance what looked like a line of low cloud over the UK. It was only as we got closer that we realised the “cloud” was the cliffs at Dover:

The track to Cap Gris Nez took us past the Eurotunnel terminal at Coquelles:

Crossing the coast, northbound this time:

Cap Gris Nez behind us…

We were a lot more relaxed heading north, the product of experience…it is never as scary as you think it will be…

Looking back from mid-channel… Au revoir, France. À bientôt…

Bonjour Angleterre. Hello England! It was a great feeling switching over to London Information and hearing the voices – just like coming home:

Approaching Dover again…

After Dover it was a straight run through Kent to Rochester. London Info was busy with UK traffic heading to Le Touquet and the Channel Islands. We also heard the Belgian guys ahead of us as they made their way towards Duxford. Pretty soon we were down and taxiing to the pumps where the pit-stop team burst into action. They even offered to push the aircraft back onto the grass for us, which meant we could go to the café…

We were half expecting a visit from the Border Force guys. We had filed a General Aviation Report (GAR) via Skydemon the previous evening (it needs at least 4 hours in advance) but nobody came to meet our arrival. Border Force will check any interesting looking arrivals and also do spot checks. The refuellers said they had been at Rochester the previous day checking inbound arrivals from the continent but we must have been too mundane to check. There is a benefit to being boring!

Rochester café’s famous bacon sandwiches. Stopping for one of these is worth the risk that the weather might beat us to Perth later! Note the concurrent flight planning activity going on on the iPad at the same time…

And off again, northbound over the Thames, looking west towards London:

Over the flatlands of East Anglia, these are the Old Bedford River (left) and the New Bedford River (right, also known as the hundred foot drain):

Following the power station route markers towards Sandtoft for fuel:

By now the high cloud was building up, sign of an approaching front…we didn’t get any pictures at Sandtoft as we did a quick turnaround and headed north again. Approaching Newcastle the western sky was turning slightly ominous…

And north of Newcastle there was some lower cloud around. Nothing to stop us progressing, but we did have to descend to 1500ft at one point to stay in sight of the surface:

At 1500ft I noticed that the 4G symbol had popped up on the iPad and the signal was good enough to load up Rain Alarm which showed us where the heavy rain was. The coastal route was clear and so we decided to press on. Some people pay megabucks to get data link weather installed but this was just as good. Due to having signal the Skydemon also updated the latest weather reports including Dundee and Leuchars, both were good enough to continue:

Coming up to the Firth of Forth at North Berwick we were able to climb again for the last major water crossing…

Then it was a straight line through Fife, before positioning to final runway 21 at Perth, with rain spotting the windscreen:

Home at last…10 days, 31.4 flying hours and about 3000 nautical miles later:

It was quite an adventure. A lot of firsts for both of us. A few niggles with the aircraft which were sorted out easily enough, and almost a whole page of log book entries, with lots of new airfields: Gamston, Rochester, Kortrijk, Groningen, Sønderborg, Höganäs, Siljansnäs, Falköping, Lübeck, Paderborn/Lippstadt, Midden Zeeland and Sandtoft…Rochester, Kortrijk and Höganäs were so good we went twice!

In over 30 hours of flying we saw fewer than 10 other aircraft. None of them came really close but I managed to alarm Brenda with some vigorous manoeuvring to “avoid” a Luftwaffe Transall transport aircraft which was actually about 5 miles away. When first spotted it looked like a light aircraft a lot closer. A bit of a Father Ted moment…

We are now looking at the various electronic conspicuity products on the market which will add traffic symbols to the Skydemon map in real time. We’ll still need to look out the window as not all traffic will show up but every aid to situational awareness helps.

We also now have a better idea of what makes a good touring aircraft. Three things we have agreed we would be nice to have are more speed, an autopilot and better baggage space. For now though, the Sting is perfectly adequate.

We are already planning the next great adventure!

Scotland to Sweden 2018 – we had a blast!
