The Holborn Assets Groblersdal Speed Navigation Rally – 20 August 2022
by Rob Jonkers
This is the 3rd Speed Rally in Season 4 for 2022, which after the weather challenges of the first three in this season turned out with pristine conditions on Saturday morning, albeit very windy later on, giving some good challenging flying conditions to contend with.
For this event the organisers looked at changing the format slightly, where instead of a Friday arrivals with
test flights and an evening briefing with dinner for an early start on Saturday changed to a Saturday &
Sunday event with competitors arriving early Saturday and a mid-morning briefing. As many of the competitor aircraft have previous test flown handicaps or event history, the number of test flights would only be limited to new entrants which could be done in the early morning prior the briefing. The idea was that first take-off would take place around midday with a finish around 2 PM, where after results would be available in the late afternoon with a prize giving and dinner for the Saturday night. This would allow a good opportunity to network and engage with friends and the local club community.
The Groblersdal Club went to great lengths to make the event successful, and also combined the Speed
Rally with a fly in, and prepared an excellent surface taxi-way in this last week to accommodate operation to both ends of the runway. Also some more firsts for the Speed Rally series, previous Race Director Rob
Jonkers passed the baton fully on to Iaan Myburgh to prepare and run the event together with David le Roux as the Race Master, and took the opportunity to fly a race type event for the very first time, prior to this either having been in the back office, route planning and directing since 2016. It was great to be taking a back seat and be on the other side of the fence….
And given this, can now report first hand the experience of flying at speed. SAPFA Chair Leon Bouttell
offered to fly the event in his Sportstar as a late entry, and after some discussion decided fly with him
navigating given my navigation skills being more rusty. At papers time I collected the envelope and had to take a brisk walk to get to the aircraft parked some 200 m away, strap in while Leon started plotting,
essentially I got a map with the route highlighted and he went to prepare the 2 nd map with minute markers to allow us to assess progress along the route.
This was concluded prior start-up and after taxi to the holding position we still had some 5 minutes to go
through the route and discuss altitudes to fly at. Barreling down runway 05 we first had to pick up speed in ground effect and have positive rate of climb prior the first turn after the end of the runway which was a steep left at almost 180 deg (the preferred take-off direction was actually Rwy 23 but changed due to wind conditions favouring 05 and it being downhill).
Not having flown the Sportstar for some time had to get used to the very light controls (compared to a C182), so the first leg was a little skittish in heading and it took most of that leg to get oriented, which resulted in a turn-point miss on turn-point 1, which most competitors found difficult to find. After that we settled down and could get on with finding the next turn-points, checking track position relative to the far field and close in features.
Around half way we sighted the Ercoupe in front of us, and proceeded to haul them in, but not long after that the Cessna 150 with Ron & Von overtook us, just to see them almost miss turn-point 8 having to jinx left and then right to get around the turn-point, this brought them closer to us again before disappearing into the distance. For sure it remains important to not lose energy around turns. Thereafter we overtook first timers Benjamin & Clinton in their Bushcat coming into the home straight, and I started wondering where were the faster aircraft behind us, and then no less than 15 seconds from the finish line the Comanche ZS-NXG, the 235 ZS-FVV and the C210 ZS-CNY came zooming past as if we were standing still, at least it looked like we must have arrived overhead in 5th place.
The wind for sure had an effect on us all, with much turbulence, and even though staying between 3500 & 4000ft, I let the aircraft drift up with thermal / wave lift where it happened, and bled off altitude to pick up speed taking advantage on the conditions. All in all great to fly one of these, and for sure there are strategies to follow, navigation accuracy to be maintained, energy management around turn-points, altitude management, it is not for sure not just a full throttle burn around a track, each element an important ingredient in achieving leader board positions as seconds count, where an average of an hour’s flight is involved.
After everybody was safe on the ground, Iaan and Tarryn got to work with scoring, and concluded this by 4PM, and then awaited the prize-giving at 6PM hosted by David le Roux. A number of competitors were not able to stay over, thus prize giving had a number of winners not being present.
For the Navigation Accuracy category, third place went to Ron Stirk and Von Hamman in their Cessna 150
ZS-NBT, in 2 nd place Willem Kruger & Cris Moolman as first timers in their Alouette 2 ZU-RAH , and in 1 st place Stefan Lombard & Martiens Marais in their Piper Comanche ZS-NXG.
For the Handicap/Speed category, third place went to Phil Wakeley & Mary de Klerk in their C210 ZS-CNY, in 2nd place Stefan Lombard & Martiens Marais in their Piper Comanche ZS-NXG, and in 1 st place Quintin Kruger & Johan Whiteman in their Cherokee 235 ZS-FVV.
Overall Winners in third place went to Phil Wakeley & Mary de Klerk in their C210 ZS-CNY, in 2 nd place
Quintin Kruger & Johan Whiteman in their Cherokee 235 ZS-FVV, and in 1 st place Stefan Lombard &
Martiens Marais in their Piper Comanche ZS-NXG.

The Witbank Speed Navigation Rally
26 March 2022 by Rob Jonkers
This first of the 4th Season Speed Rallies for 2022 has been held at Witbank, organised by SAPFA and hosted by the Witbank Aeronautical Association. This is the 3rd event held at Witbank in the series, which also had to be postponed due to weather issues on the original date of 5th March, the weather forecasting being fickle at best, but looked eventually flyable on the 5th, and as Competition Director you are damned for making those weather related calls…. one way or the other, especially up here on the reef where weather changeability is so prevalent within hours.
With the change of date also saw some competitors having to withdraw and at least others could join. Similarly we had officials planned that also had to drop out, but the WAA stepped up with an additional ground support team to help out, with the end result we had a fun & safe event.
There were 20 entries, but with the early morning weather situation on the highveld, many attempted to get to Witbank, but had to turn back or could not take-off, reducing the field to 15. Only two competitors had arrived on Friday before significant thundershowers made their appearance.
The traditional Friday evening briefing was cancelled, so the full briefing was then planned for Saturday morning, where after the club provided a nice Friday dinner spread and for the teams, officials and club members, before retiring for the evening.
Saturday morning dawned with more promising weather, the predicted low cloud did not materialise, and by 9 am the cloud base had risen to around 6000 ft, with light and variable wind. The briefing was delayed to 9h30 am and was concluded at around 10 am, where everybody dispersed first for a group photo and then to park their aircraft and prepare for the scrutineers. The route for the day was one with a cross over to the east of the field, with the first series of legs to the north-west, and the 2nd series of legs to the north-east.
1st take-off was planned at 11h20, and arrivals at 12h45. With all the competitors off towards the northwest, the route had a mix of easy and challenging turnpoints, especially TP6 which required good navigating skills to find the dust road intersection from amongst the same colour surroundings, from the results this turn point seems to have been difficult to home onto. There were two groups coming over the line, those that were a bit early as they had got waylaid along the course and a group that were accurate with their navigating skills getting over the line close to their handicap times.
After all teams having returned and safe on the ground, the scoring team got to work to analyse the results, with the tracks for a number being quite accurate, although some had wobbles, three had got significantly lost. As everybody essentially left for home, it was left to the scoring team to complete their work off line, and hold a virtual prize giving as done at previous events, which was done at 8 PM.
For the Navigation Accuracy category, third place went to Quintin Kruger & Johan Whiteman in their Cherokee 235 ZS-FVV, in 2nd place Apie & Frederick Kotzee in their Robinson R66 ZS-HRS, and in 1st place Hendrik & Jandre Loots in their Sling ZU-IHK.
For the Handicap/Speed category, third place went to Quintin Kruger & Johan Whiteman in their Cherokee 235 ZS-FVV, in 2nd place Hendrik & Jandre Loots in their Sling ZU-IHK and in 1st place Apie & Frederick Kotzee in their Robinson R66 ZS-HRS.

SAPFA Rally Training Camp
SAPFA Rally Training Camp – Aerosud Premises 18 January 2020 –

SAPFA held a very successful training event on Rally Navigation on Saturday 18th January as the first SAPFA event of the year. Building on the successful event held last year at the same time, we decided to hold another one, particularly that this year is the year where SAPFA hosts the World Rally Flying Championships in November in Stellenbosch. There were 30 participants for the day, including many of the current SAPFA Protea team members who were assisting the trainees and our media friends. The Aerosud canteen was again the venue of choice lending itself well to this size of training camp.
It is great to see the sport being supported so enthusiastically, and the willingness to learn these basic skills of map reading and planning. The Chairman of SAPFA opened the camp with a brief outline of the plans of SAPFA in terms of events for the year, that the Aero Club also holds its Centenary year resulting in a packed calendar for the year, and from that look at developing and exposing particularly the youth to recreational aviation.
The Participants – 30 in total
With that Mary de Klerk took charge and laid out the objectives of the day, by initially going through the theory of plotting, and then to practice on an actual plot. With this year of 2020 having a full event calendar, and the Nationals coming up in April in Stellenbosch, this training event would serve as an excellent platform to entice new members to the sport and to start training for the Internationals and obtain Protea Colours.
Mary first started off with having everybody introduce themselves, and what they each had as objectives for training, some were there as newbies interested in taking part in the sport, some having taken part previously indicated they needed some formal and expert training, and some others indicated they just wanted to delve more in depth than what a ppl course would give on the art of paper based navigation.
From there Mary outlined the theory on plotting procedures and described the tools of the trade. Then it was off to plotting an example course which had to be done from basic plotting principles of co-ordinates, bearings (which could be in either true or magnetic) and distances (either in nm of km). Each turning point then had to be found and identified and linked into legs, some of which could be arcs or follow map features.
The goal in getting to National level standard is to be able to plot in the aircraft with a papers time of around 30-40 minutes prior take-off, which means speed is of the essence in doing the plot, so that the navigator can assist with finding and identifying the ground photos.
The morning’s training ended off at around 10h30 am, and after a short break, everybody got organized on plotting the example route provided which was the 2019 Rand Airport Challenge, got the laminated transparent tool, which they had to cut out, and proceeded to plot each of the turn points making up the route up until Turn Point 4, and after lunch at around 12, continued to finish the plot to the Finish Point.
After the plot was done, Mary opened up Google Earth, and “flew” the route along the plot lines to show where the photos were, and what they would look like against the photo sheets that are provided. This then effectively ended the day’s training at around 2 PM.
Everybody left with some knowledge gained on plotting and techniques of planning & flying a rally, and it is hoped that many will come to the Rand Challenge on the 25th January and Nationals in April.

As a follow-on to the Rally Navigation Training events held at Aerosud on the 19th of January 2019, it was planned to fly the practice route that was plotted on that day. The 16th February was chosen and as the week unfolded with almost daily rain, it looked auspicious to get good weather, although it looked a little promising on Friday. As the day dawned, the clouds were on the deck throughout Gauteng, north of the Magalies in the Brits area was a bit better. The cloud base only started lifting around 9 am, and then only in patches, so even with 12 teams registered to take part, only 4 teams eventually were able to get to Brits. Frank & Cally Eckard prepared the route packs for the teams and were on hand to do the scoring.
Frank Eckard – Presenting the Rally Flying Techniques Course
The focus of the day was more related to flying techniques and Frank Eckard provided an hour’s presentation on how to prepare the cockpit, roles of the crew in work sharing, organizing the photos, flying techniques such as speed management, altitude, approach to turn points.
Nigel Hopkins & Mary de Klerk preparing their maps for their flight
The teams then plotted the course, basically replotted the course that was previously prepared a month ago, and went to fly the route. Aerobatics ace & SAA Captain Nigel Hopkins who has been a previous rally world champion 15 years ago, flew with experienced navigator Mary de Klerk, and proved by his excellent score of 64 penalty points that he has not lost his touch in rally flying.

As SAPFA is preparing for the World Rally Flying Championships in 2020, the focus on these two years prior the event, is to gain as many South African qualified teams to take part, and every event being held this year will be an event that can improve skills.
Nigel & Mary preparing the cockpit
To achieve world standard qualification, there is a route to achieve these skills in classes, with Advanced Class as the definitive level of competition, where existing Protea teams would compete and new teams would vie to achieve a qualification standard. The initial Sportsman’s Class is the entry level where teams gain experience to get to try their hand at the Advanced Class. There is also an Intermediate Class, which has a combination of Protea pilots and navigators that fly or navigate with new team members as further skill building in a step to achieve an Advanced level.

The next rally is being held at Virginia on the 26th March, and as the weather was not favourable on this weekend, SAPFA will look at rescheduling this event again at a future date.
