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 SAPFA Secunda Speed Rally
The SAPFA Secunda Speed Rally – 28 August 2021 by Rob Jonkers
This year we have returned again to the birth place of the Speed Rally, being the 4th time this event has been held here, with 2018 the start of Season 1, and from 2020 having re-aligned the Speed Rallies to calendar year seasons, with this event being the 3rd event in Season 3, with the final event for Season 3 being at Springs on 27 Nov 2021.
With lockdown still at level 3, we limited the entries to 25 teams, and 22 had entered by the time the event entries closed on Friday 27th August. Our host club with Chairman Ashvir Kallis and Vice Chairman Lourence Mathee went all out to support the event, making the club facilities available and a braai for the Friday evening. The Aviation Junction flight school made their school facilities available for the scoring and officials team.
The weather outlook was looking challenging as the weekend was approaching, many warnings of severe cold and high winds predicted from a substantial cold front, and at dawn on Friday much low cloud and rain squalls made their appearance across Gauteng, which cleared later but with increasing gusty wind conditions. Having left Kitty Hawk at 10 am, caught a 30 kt tailwind to Secunda and had to deal with a 15 kt crosswind on landing. Around half the field chose rather to arrive early on Saturday, with some test flights also delayed to Saturday morning. The test flights were ably handled by Mauritz du Plessis and Iaan Myburg, with Iaan also taking up the role of scorer for this event having developed new scoring software.
At 18h30, Jonty Esser as the MC and Race Master introduced Rob Jonkers who took to the stage and provided a briefing on what to expect for the next day in terms of the planned route, how many turnpoints, distance, departure and arrivals protocol, and also how the scoring system would world work and the expected weather conditions. This year’s route would include a cross-over, which would bring more spectator interaction as the aircraft came over the field at the half way mark.
Jonty Esser then took to the stage in his signature competing crew introductory theme song videos and race number handouts, and also including introductions to the team sponsors, which has picked up this year after a disastrous 2020, and great to see the sponsors returning to support their teams. A scrumptious braai was laid on by the club to end the evening with around the fire stories on a high note.
For Saturday the briefing started at 8h00, which was a shortened version just to cover the basics of the route, radio procedures and weather, which at least had improved wind conditions from the Friday, starting out at 10 kts with a maximum of 15 kts predicted in a westerly direction, which would at least be favourable for runway 29. Some line squalls were also in the area, with the cloud base at least more than 1000 ft, with good visibility.
With the briefing over, teams prepared their aircraft, while the organisers got the papers ready. Each team would then receive an envelope with a map, turnpoint photos, a minute marker and a GPS logger to record their track. Aircraft were then also scrutineered with all portable electronic devices sealed up in bags. For this event Mark & Shane from Century Avionics were on hand to also block off / seal Aircraft GPS and autopilot systems, and also checking the fuel tanks were full.
The Pilot Insure Scrutineer Team were on hand to seal up all portable GPS capable devices, with the papers team under guidance of Lizelle handing out papers at the allotted time, Chief Marshall Adrian Cronje and Starters Mauritz & Chareen set up at the starting line adjacent the threshold of Runway 29, who would release each aircraft at their allotted time slot. Each team then received their envelopes with their loggers at 20 minutes prior take-off time, taxi to the starting line within 10 minutes of brake release. 1st take-off was at 10h20 for the slowest aircraft which was a Magni Gyrocopter (the first time a gyro has taken part) and last take-off at 11h10, with planned arrival at 12h00.
With all the competitors off towards the south west, the route had a mix of easy and challenging turnpoints. In general the competitors found the course easy enough. At just before 12h00, the first aircraft over the line was a little early, and then followed by at least three quarters of the field within 1 minute, with tail enders after that.
After all teams having returned, the scoring team got to work to analyse the results, completing the individual scores by 14h00, with prize giving planned for at 15:00. In the meantime, most of the competitors being concerned over deteriorating weather decided to return to their home bases, thus a call was made at 14h30 to rather hold a virtual prize giving, which Race Master Jonty carried out at 5 PM on the WhatsApp platform. MC Jonty Esser thanked everybody in the Speed Rally series for their contributions.
The winners in the handicap category were Deidre Batchelor & Dave Naude in their Jabiru ZU-EBU, in second place Mike Blackburn & Steve Briggs in a Sling ZU-IBM and in third place the Evans Racing team Jonty & Jonathan Esser in their C150 ZU-BLL. The first thirteen placings were the only crews who managed a clean penalty free round.
The winners in the accuracy category were the Gem air sponsored team of Phil Wakeley & Mary de Klerk in their C210 ZS-CNY, in second place Fanie Scholtz & Herman Haasbroek in their Sling ZU-FZF, and in third place Leon Bouttell & Martin Meyer in their Evektor Harmony ZU-FWS..
Overall Standings are in first place father and son Apie & Frederik Kotzee, in second place another father and son Johan Whiteman & Quintin Kruger in their Cherokee 235 ZS-FVV, and in third place another father & son team of Hendrik & Jandre Loots flying their Sling ZU-IHK. This is the first time the first 3 overall placed teams are all father and sons.
Many thanks to the Secunda Aero Club for hosting this fantastic event, the SAPFA team of Adrian Cronje as the Chief Marshall, Nigel Musgrave as the Safety Officer, Iaan & Tarryn Myburg doing the scoring, Mauritz du Plessis doing test flights and starting, Marc & Shane from Century Avionics for Scrutineering, Chareen Shillaw as the Event Secretary, Lizelle Kruger, Clarissa Dacostaesilva, Ariana Rompel, Leonie du Plessis for handing out competition papers to the crews, the Pilot Insure team under David le Roux for Scrutineering, Jonty & Lizelle & Sandi for putting together an awesome Friday evening launch event, and Anneke Pretorius for looking after officials lunches. Santjie & Jean Marie White were also on hand to ensure all aircraft are accounted for during and post the event.

SAPFA Rally Flying Training Camp – Brits Airfield 16 February 2019
SAPFA Rally Flying Training Camp – Brits Airfield 16 February 2019 – by Rob Jonkers
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.
