Turbulent times

It seems that I am going to log a decent month’s worth of flying in September. We are making the most of the lack of restrictions and enjoying the freedom of being able to travel anywhere we want.

19 September2020ZU-IBMFAGM(Rand) – FASY(Baragwanath) – Florence Guest Farm – FAGM2.7220

We’ve been meaning to go to the Florence Guest Farm at Chrissiesmeer for some time now – the last few times we’ve tried we have been unable due to low clouds. The Eastern part of the highveld plateau in South Africa is plagued by morning mist almost throughout the year due to adiabatic cooling of moist air flowing in from the Indian Ocean.

However, on this instance we were to be blessed with fantastic weather. Roger and I are both in the same hangar so we set off more or less together to Baragwanath to pick up Matthew in the Mooney. Once the usual suspects were reunited we set off East for Chrissiesmeer. We’ve figured out the timing pretty well now – if I leave first then Matthew in the Mooney 5-10min later and then Roger in the Arrow 10 minutes later, we will all arrive at more or less the same time.

Somewhere around Heidelberg

It was actually a beautiful morning for flying – so smooth in fact that my 14y old was delegated poling duties and he did a pretty good job – the difficulties of VFR in the morning haze notwithstanding. He is going to want to learn to fly so he might as well get some stick time and the advantage of doing it from the right seat is that there is less ability to rely on the instruments for attitude.

Relaxed at the controls – note the light grip!

With ATC helpfully providing separation info between the three of us we made it to Chrissiesmeer in good time. The hamlet is known as the Okavango of South Africa which I think is pushing it a little, but there certainly are a large number of lakes in the area, and it is very pretty from the air. I suspect in summer it is even prettier as the winter landscape can be somewhat drab.

Layer of pollution from Secunda’s Sasol oil-from-coal plant. Yuk.

I was last to land having flown a very long downwind to give the others time to backtrack on the grass runway. These rural airstrips in South Africa almost always seem to have large eucalyptus trees on the undershoot which are always good for focusing your attention on glide path discipline – no dragging it in here…

The runway is well kept but in all honesty, its really pretty bumpy and the left side is quite unkempt. Backtracking, we parked up next to the other two aircraft and set off in search of breakfast.

Despite arranging for breakfast to be available the staff were somewhat nonplussed at our arrival but they quickly whipped up a reasonable egg and bacon breakfast while we had a look around. The venue is marketed as a wedding type place with some overnight accommodation – it looks like a great spot for the quick overnight escape from the city and we’ll put it on the list of potential destinations for this sort of trip.

With the obvious exception of the actual flying the best part of these breakfast runs is sitting around and chatting while eating breakfast. After breakfast I was able to fly the drone a bit (after making sure there was no traffic in the area!) and then we set off home. There was some discussion about heading to the EAA Taildraggers flyin at FAWA but since we’re all blessed with nosewheels we decided to give it a miss and head straight back to Rand.

Later that afternoon the first thunderstorms of the season struck but at midday when we were flying back we were very aware of the convective activity – this was easily the worst turbulence since my flight back from Cape Town – we couldn’t find a comfortable level and had one or two of those ‘bang your head on the ceiling and dislodge your headset type moments’. It’s always entertaining when ATC asks why you’re 200ft above your planned cruise level when you’re at idle throttle, 7degrees nose down with a 900fpm climb rate.

We landed at Rand about 10minutes before the first storm rolled through (from the other direction) and stuffed the plane into the hangar. Summer is definitely on it’s way and flying needs to start happening earlier!

Competition flying again

The fluttering noise didn’t catch my attention as much as the white flash of paper passing before my eyes. Flailing wildly didn’t help as the paper in question – the photos of the start and finish gates – flew out the gullwing door of my Sling, and contrary to what would be expected, got sucked into the propeller from behind and shredded.

This was going to be a problem. One does not simply chase after pieces of maps while holding short of an active runway for a set takeoff time. Our Air Navigation Rally second course was about to get even more interesting. It wasn’t lacking in interest before the map shredding incident – the 30kt winds had provided quite enough entertainment already this morning.

On being flexible

The reality of single engine piston operations is that one tends to be at the mercy of the vagaries of the weather. This shouldn’t be news to anyone really but it was brought home to me last weekend on an attempted flight to meet a friend for a quick coffee at Rustenburg (FARG).

After some days of marginal weather (and, it must be noted, some spectacular weather weekends where there was simply no time to fly), it finally looked like my schedule and CAVOK were lining up. The plan was to fly from Baragwanath to Rustenburg, have a coffee and head back.

EAA (SA) Sun ‘n Fun Flyin 9 November 2019

The South African chapter of the Experimental Aircraft Association is celebrating it’s 50th anniversary this year. Every year there is a flyin to the Brits Airfield (FABS) but this year promised to be even more special. Any excuse for a flight is a good one, so it was off to Brits I went.

As summer starts to take hold it’s getting light earlier and I was able to pull the plane out at 6h30, in pleasant conditions with the low morning clouds clearing away and only the slightest breeze. I should have realised it was too good to be true…

As I rolled down runway 13 (into the sun – of course…) I noticed 3 Guineafowl taxiing out onto the runway ahead of me. Now a guineafowl is not a small bird – they probably weigh around 4 kilograms and stand about 35cm high – I didn’t fancy the idea of one of them going through the prop or hitting a wheel. In retrospect I made the wrong call by rotating 2-3kts below nominal rotation speed (50kts) but IBM eagerly kept into the air and disaster was averted. It would have been better to stay on the ground, wait for normal rotation and try to ignore the birds than to take off early and potentially stall out. Fortunately I was so close to rotation speed that it made no difference but definitely something to think about for lower speed incidents – better to hit a bird on the ground than stall it in.

The other concern is that the birds could have tried to fly and then I may have been in the situation where I’m flying at low speed and then hit a bird….

Bird excitement behind us, we climbed up under the Johannesburg TMA – cruising at 7500’ and routing to the west of the Lanseria class B airspace. We passed over Orient airfield (a major gliding Mecca), but it was too early for the obligatory powerless landers in their funny hats.

Couldn’t resist….. sorry not sorry

This dogleg set up a more or less direct course to Brits – and a routing directly into the teeth of a not insignificant headwind – 30kts on the nose meant we took a lot longer to get to Brits at only 90kts over the ground.

For the (anticipated) large flyins, the CAA usually declare an Aerodrome Flight Info Service (AFIS) which means that the usually unmanned airfield is manned with a tower operator whose role is to ensure separation but does not give explicit landing or takeoff clearances – it’s a little bit strange – the landing clearance usually sounds like “ZU-IBM, number one on the approach, land at pilot’s discretion”. Anyhow, as it turns out they were only opening at 07h30 and I arrived overhead at 07h25. This resulted in some confusion with arriving aircraft coming from 4 directions and all trying to ascertain if the tower was open or not.

Flying in other people’s airplanes – Classic Mooney

Having an aircraft in maintenance does very little for the desire to commit aviation. Out of necessity (see previous posts on moving aircraft for maintenance), I had left my vehicle in the hangar when I took my plane to Tedderfield so I needed a lift back to Baragwanath – which Matthew kindly offered. Of course, why would anyone go to an airfield unless it was to fly an aircraft – and he was off to fly his (recently returned from annual inspection) Mooney M20C short body.

Matthew very kindly offered me a flight in the Mooney, to which I gave due consideration (about 500msec) and agreed. The Mooney is a very different aircraft from the Sling. The Mooney styling has always appealed to me, there is something about that forward swept tail and the low slung stance which suggests that it will go fast. The Classic Mooney has a very 60’s look about it (which it probably should!) – the very steep windshield and the ‘big gulp’ air intake are unique design features. Even this short body variant’s tail is very low to the ground and I must say that this would worry me quite a lot in the landing.

Bethlehem Airshow 2019

One of the joys of having an aircraft is having the ability to fly in to various airshows, especially those that you would never have considered attending due to the distance. Bethlehem (FABM) lies about 99nm south of Baragwanath, an easy hour’s flight. It would be a shame not to take the chance to attend what is generally considered to be an excellent airshow.

DIY External Aircraft GoPro mounting

I’m getting a little bored with the in-cockpit got GoPro shots. I feel like there are only two angles really – either out the front or looking at the wing. While these do have some interest, I’m keen to try some external camera shots. 

The problem here is airways going to be how to safely attach a GoPro to the exterior of the aircraft. Safety here is two pronged – one doesn’t want to interfere with the aerodynamic performance of the aircraft. Neither does one want to be responsible for GoPro sized dents in structures or people on the ground. 

I’d imagine the CAA/Police/justice system works take a dim view of damage caused by falling action cameras. Additionally, you can’t simply attach objects permanently to an aircraft. With this in mind I’ve been looking at getting a mount to capture footage like this. 

There are a number of options and ideas to achieve this. The easiest way is to simply use the GoPro suction cup and apply it to the wing. Look. The cup grips well. But I wouldn’t like to bet my GoPro on it. So that idea is out. Then there are some proprietary mounting systems sold mostly on Amazon – flightflix and nflightcam being the two most prominent brands. But they are really expensive, especially once shipped here. 

So I thought I’d have a go at making one myself based loosely on the flightflix tie down mount.
