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.

The Flight of the Navigator (or something like that)

I’ve previously written about flying in a speed rally – where we fly a set course against our aircraft’s handicap speed. It’s fast and furious and exciting with lots of close up flying. The other class of competition flying is the Navigation Rally, which I was lucky enough to be a competitor in this weekend.

My aircraft is still undergoing annual inspection (well, actually as I write, the inspection is complete – we are waiting on a post maintenance test flight for it to be signed out again), so I was to be the designated navigator for Matthew in the Mooney. Whereas a speed rally is simply flying a course as fast as possible (and reasonably accurately), the navigation rally is quite a lot more complex. The papers that are given to each crew contain turn point descriptions, a 1:200000 topographic map, a sheet of photos of turn points and places to spot and a time sheet based on a nominated speed.

Secunda Speed Rally 2019 – Day 1

I’ve been trying to get involved in competition flying for a long time, but it has always seemed to not work out for one reason or another. I’ve been able to go to see the rally taking place at Middelberg and Springs in the past but haven’t been able to take part. This weekend though, everything seemed to fall into place with a public holiday on Friday and the race being held nearby at the Secunda airfield (FASC) on the weekend.

Competition flying in South Africa seems to be undergoing somewhat of a resurgence at the moment after being stuck for years in a stodgy cycle of President’s Trophy Air Races marred by legal cases and appeals. Three event formats are currently taking place – Speed Rallies, Navigation Rallies and Fun Rallies. They are being held through the country (although mostly in the northern half, fortunately). Fun rallies involve flying a short course in a very narrow corridor, points being deducted for excursions from the corridor. Navigation rallies are plotted and flown to specific times and locations and are the more traditional form of competition rally flying in South Africa.

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.

Nylstroom Taildraggers (Almost)

Every year, The Nylstroom Airfield (FANY) plays host to a weekend of taildraggers. Folks fly their non nosewheel equipped aircraft in on the Friday or Saturday and stay over and (probably) have a few drinks in the evening and fly back on the Sunday morning. It is a celebration of all things Taildragger and aviation in general and I was keen to go see what it was all about. 

Unfortunately, life had other ideas and my plans to fly in for a visit on the Saturday did not come to fruition which left me looking at popping up on the Sunday – basically for no other reason than having an excuse to fly the aeroplane. The day’s schedule called for a family lunch which meant I was under a little bit of time pressure – but the best time of the day to fly is the early morning and it was only me so no need to accommodate any late sleepers.

Aero South Africa Exhibition

General aviation is widely accepted to be in somewhat of a decline in South Africa. Thus it is quite exciting when an exhibition aimed primarily at the general aviation sector is scheduled – look, it’s not Oshkosh or Sun ‘n Fun but this is about as good as it gets for us locals. It is also quite unusual in that there was no airshow scheduled – only static and trade exhibits. The exhibition is Aero South Africa and it was billed as an offshoot of Aero Friedrichshafen

Currency vs proficiency

The other day I offered to help one of our club members to move his aircraft to another airport for its MPI/Annual. No problem, right? Except it’s a controlled airport I’ve never landed at before (at least during the day – I did a touch and go there on my night cross country but the tower was closed).

This did give me some room for pause – it’s an easy airport, 2 runways, wide runways but there are some issues. Firstly, the airspace is busy – there are a lot of flying schools on the field and a fair number of commercial GA operations. Secondly, the airport is crammed tightly against the Class B (TMA) airspace of O. R. Tambo international airport (FAOR) and they don’t take kindly to bugsmasher’s violating their territory.
