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.

Aero Expo South Africa 2022
Aero Africa was passionately welcomed back to Wonderboom National Airport in the city of Tshwane, South Africa, this past week and adding Saturday for some of the public to attend the now 2nd edition of the general aviation trade show.
This being Africa’s largest general aviation trade show, covers the full spectrum of services and products for the aviation industry. Discover what direction developments in the General Aviation industry are going.
This years expo was a bit smaller as the previous Aero Africa that took place for the first time back in 2019.
Due to the fact that planned returns of the expo were to take place in 2020/2021, got cancelled due to the all now well known covid-pandemic.
As that being said, we can now appreciate the event is back and we and the industry can only grow stronger going forward.
Visitors were welcome to fly-in to AERO South Africa in their own aircraft for the proceedings of each of the three days.
That including free landing, approach and ground handling fees for fly-ins to the event.
Potential buyers had the opportunity to experience aircraft features first hand as aircraft manufacturers and distributors having the opportunity to host demonstration flights during the event.
A workshop area hosted reputable speakers covering relevant topics were available during the course of the days of all different products, companies ect.
Aero South Africa attracts a broad and international exhibitor base with innovative products new to South Africa by incentivising product launches and global imports.
An interactive platform offering exhibitors and visitor the perfect environment to build and foster relationships with current and future business partners.
Features at AERO South Africa 2022
A private workshop area is available to host seminars and talks at AERO South Africa 2022.
As well as a medium size static park with a number of fixed wing and rotary aircraft on display.
Some of the big aviation companies that were exhibiting such as Absolute Aviation, National Airways Corporation, Cirrus South Africa, Airbus Helicopters, Excujet, DJA Aviation, Flight Schools, Air Ambulances just to name a few.
The airport itself was still busy with charter flights, flight training schools, test flights from the airports local maintenance facilities.
This made up for some as many of the general public thought the event was an airshow but in fact and expo.
A wet and cold PTAR 2022
A wet and cold PTAR 2022 at New Tempe Bloemfontein – By Rob Jonkers
This year’s Presidents Trophy Air Race was held at New Tempe Bloemfontein, and traditionally held on the last weekend of May, but with the advent of the Botswana Air Show also taking place on the same weekend it was decided to move it a week earlier, which if we all had the perfect hindsight, with that event not happening, we could have held it on its traditional date, and subsequently avoiding this last few days of most unseasonal weather that befell the race weekend.
This year for sure has had many of the planned aviation events disrupted by wet, cold, windy weather systems, the most bandied about term of “cut-off low” being used to describe the weather situation. This weekend no less had a very large cold front coupled with an intense low-pressure system over the centre of the country affect the plans to race.
I arrived on Wednesday in excellent weather conditions and started setting up for the race, mostly the race control room and preparing for test flights, some of the early competitors also started to arrive at the field. Thursday saw all the aircraft arrive, some of the Cape based teams first had to wait for the front to pass before setting off, arriving just before dark. Most of the day was taken up by flight tests and registration and watching what the weather would be doing for the next day as the front was approaching.
During the first extensive Thursday afternoon briefing which also included the SA weather services team being on hand to give us the best outlook it appeared that there may be an early morning flyable gap, thus the day was planned with an early 7h30 start. As Friday dawned, it looked promising, cloud base was at a reasonable 1000 ft, and we proceeding briefing and sent the turnpoint marshals to their locations, this being particularly important to get weather condition updates from them at the furthest corners of the route.
As the morning progressed with a planned 10 am first take-off, the news from the turnpoints were not good, and then light rain started, it was then decided to scrub Day 1 with a debrief at 11 am to plan for the next day. The prediction for Saturday would be that the weather would improve from midday onwards. Everybody dispersed for some rest for the rest of the day.
Saturday dawned with flyable conditions, and in fact the window opened up from 11 onwards, thus at briefing the first take-off was planned for 11. The turnpoint marshals were sent out, who from the previous day’s rain had challenges of negotiating almost impassable roads to get to their intersections, fortunately they all sent in confirmation of being in position prior the first take-off.
This year’s field attracted 37 entries, which is very low by PTAR standards, which would normally have 60+ competitors, this year for sure the cost impact would have been affecting most would be competitors, given the fuel price virtually double that of last year at the same time. Three competitors had to withdraw mostly due to not being able to get to the event on time, thus we had 34 starters.
With the airfield being water logged, we decided not to move the aircraft from where they were parked, and carried out scrutineering in-situ and changed the papers time with a few additional minutes for the crews to collect their maps and route envelopes, which worked out well. The ground marshals were also very efficient in getting the start order taxying out at their allocated time. With the race under way, and having a cross over route, we could all watch how the order of the aircraft would be coming back over the field which was at around one third race distance.
Although the traditional race finish would be at 1PM, and given the weather window having a later than normal start, the finish was planned at 13h45, and as the time got closer to finish, the weather was threatening to deteriorate, with sudden cold and dark clouds forming just east of the field, which fortunately stayed away. The line finishers were close between Race 2 Bosbok, Race 14 Piper Commanche, Race 45 Harvard. With spacing between aircraft at the start being required to keep a safe distance, the finish order became Race 45 Harvard ZS-WSE, Race 9 RV-7 ZU-VZJ, Race 14 Piper Commanche ZS-NXG, who were the handicap winners.
Prize-giving was held at the Windmill Casino, which had laid out an excellent banquet hall for all the teams, club members and officials to enjoy. The evening started with a short debrief of the race, some of the best and “interesting” tracks being shown. Race 19 had a “long” day having lost their way at turnpoint 1 continuing northwest for 20 nm, before realising their error, they had the presence of mind to return to that first turnpoint, and continue from there to fly a good race further, only picking up one penalty, but of course adding almost 40 minutes to their time.
After the main meal, David le Roux the Race Master started the proceedings for the rest of the evening, first up Franz Smit who introduced and thanked all the sponsors supporting the race, Pilot Insure, Holborn Assets, Aircraft Finance Corporation, DJA Aviation, Century Avionics, and all the local Bloemfontein sponsors, Leon Bouttell was up next as the SAPFA Chairman, and at this point announced that Rob Jonkers would be standing down as Race Director, the baton being handed over to Iaan Myburgh.
Rob took to the stage thanking all for their support since 2018 when the Race was handed to him, at the same time an evolution of the format having been developed to today’s standard of a 10 turnpoint race limited to 300 nm, with an accuracy component added as well. There is still much discussion about this race format and its merits compared to the traditional 4 corner race, and this will be for the next Race team to work together with the racers for their input. Just as Formula 1 evolves with technology improvements, so must the PTAR evolve to take into consideration changes in technologies utilised, such as GPS based heading reference devices, different engine types that have variable power settings, these all affect the handicap speeds and course accuracy.
Rob went on to thank all those involved in the race organisation, particularly the Bloemfontein Flying Club under the key organiser Andre Grobler and experienced PTAR event coordinator, who had provided the ground marshals, turn-point marshals, and all the catering at the airfield. Nigel Musgrave as the Safety Officer with the ATNS team of Ricardo Afonso, SA Weather Services, ARCC, Bloemfontein Emergency Services team of Braam van Zyl, the CAA Special Air Events team, the local Municipality & SAPS.
After this the long awaited Prize Giving was held, with 24 trophy categories being handed out, up until the top 3 places, with third place going to Race 9 RV-7 ZU-VZJ with crew of Johan van Zyl & Eric Addison, second place going to Race 45 Harvard ZS-WSE with a crew of John Sayers & Dion Raath, and the PTAR trophy going to Race 14 Piper Commanche ZS-NXG crewed by Stefan Lombard and Martiens Marais.
After this the PTAR flag was handed over from BFC Chair Deon Loots to Jock Nel the Chairman of the Middelburg Aero Club as the 2023 PTAR event location. Thanks go to everybody who makes this event a success, especially the volunteers who take time out to assist, also the media who are key to promoting the PTAR.
