The South African Power Flying Association (SAPFA) together with our main sponsor Aircraft Unlimited, organised the 2020 season finale Speed Navigation Rally on Saturday 28th November 2020.

Although strictly not planned to have been the end of the 2nd season, 2020 being a year what it is, with reduced events, we decided to review the events and shorten the 6 per season to 4, so season 2 started and ended at Springsin order that season 3 would start and end in 2021.

For the overall season, scoring the best of 3 events would count towards the season’s results.

As the event has evolved, changes have been brought into play, all with the participation of the organisers and competitors. For this season the overall distance was reduced to 138 nm (from 150 nm), a handicap overspeed penalty was instituted and allowance to fly with a GPS track-made-good magnetic heading reference. For this final season 2 event, 32 entries were received. Springs 2019 was also the debut of the Grand-Prix circuit and was also planned this year, a format that has also evolved over the last four GPs.

The route was mostly to the east and south of the airfield, with a bit more of a scenic route than previous events going close to the Vaal Dam. The weather on Friday started out really well, the forecast giving an indication to late afternoon thundershowers, which were lurking towards the west. Test flights commenced with some new entries requiring test flights and some old entries wanting to retest to re-confirm their handicaps. The test flights were done by Mark Clulow and Sean Cronin and had to be curtailed after 3PM as the weather deteriorated.


Saturday mornings briefing

At 18h30, Jonty Esser, as the MC 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 turn points, distance, departure and arrivals protocol. He also elaborated as to how the scoring system worked in terms of penalties as well as the expected weather conditions, which looked like overcast to start with but lifting after 9 am and 10+ kts of gusty northerly winds.

Jonty Esser then took to the stage in his signature competing crew introductory theme song videos and race number handouts and also included introductions to the event and team sponsors. For this event, an event sponsor was secured in the form of Aircraft Unlimited, an AMO based at Rand Airport. Jonty proudly introduced the new owner Andrew Lester and his team and advised that they would also provide AMO support for aircraft during the event. Thereafter everybody was treated to a buffet meal before retiring for the evening to the music of one of the competitors Leon Joubert and his band re-living the 70s real music era.

Saturday morning dawned with windy and low overcast cloud conditions. The decision was made to start the briefing an hour later at 9 am with the start to commence an hour and a half later at 11h30 for an over the field arrival at 1 PM. Once the shortened briefing was over, everybody prepared their aircraft and got themselves sorted into the parking bays. 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.

Scrutineers Lizelle, Louna, Bernhardt and Adrian were on hand to seal up all portable GPS capable devices, handing out papers at the allotted time and also checked the fuel tanks were full. Starters Mark Clulow and Sean Cronin set up at the starting line adjacent the threshold of Runway 03, 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 and taxied to the starting line within 10 minutes of brake release. 1st take-off was at 11h30 for the slowest aircraft and last take-off at 12h100 with a planned arrival at 1 PM.
With all the competitors off towards the east, the route had a mix of easy and challenging turn points with some river crossing also thrown into the mix and a little more scenic than previous Springs events. In general, the competitors found the course easy enough this time round, with the photographs now in larger format to identify the ground features more prominently and which can be seen in the results, where many had a clear round in their tracks. Just before 1PM, the first aircraft appeared over the line and was a little early. It was then followed by at least three quarters of the field all within a 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 3 PM. A season ending gala prize-giving evening was arranged, which turned out really well as most of the teams stayed over or got dressed in their finest black tie. The evening got under way at around 6 with starter platters and then at 7 with Rob Jonkers showing everybody’s tracks – from the most accurate to the most creative. Jonty had Andrew from Aircraft Unlimited and Rob Jonkers hand out certificates to each of the teams. Prize-giving got underway with three trophies going to best husband and wife team – Eric and Antoinette Addison, best Father and Son team – Apie & Frederik Kotzee and best school entry – Legend Sky from Rhino Park. The most creative track trophy went to the first-time entrant Chipmunk team of Grant Timms and Duncan Ritchie.

This was followed by the Springs event results in navigation accuracy, handicap and overall. As this was the end of the 2nd season, the season results and winners in each of the categories were also announced. The final results for all the teams for Springs and the season will be posted on the Speed Rally website.

The SAPFA Landing Nationals – 7 November 2020

By Rob Jonkers. Photos by Jaco Pitout

SAPFA holds a Landing National Championships on a yearly basis and this year it was scheduled to take place at Stellenbosch, on this same day as part of the start of the World Rally Flying Championships. Sadly, as reported earlier in the year, this had to be postponed to 2021 in the same time frame. At least we have been able to redirect the original plan to hold the championships up here on the reef and Brakpan was chosen as the venue. 


With the rain having passed earlier in the week, the weather turned to sweltering with 34 deg C as the high temperature for the day. With the airfield elevation at 5300 ft, this resulted in a density altitude of around 8500 ft, not the most ideal conditions for high altitude landing accuracy. The wind was at least relatively calm, although gusty at times.

 There were 14 competitors for the day – 8 in the Unlimited class and 6 in the Sportsman’s class. Many of the competitors were out practicing on Friday for a good part of the day to gain proficiency in their accuracy, as the previous week’s training camp was ‘winded out’ with high cross-winds. From the results, it showed clearly that practice makes all the difference. One has to create an airfield mind map of markers, turning points and altitudes especially for glide approaches – to get a repeatable landing point.
 

The competition consists of carrying out two sessions of four landings, one a normal powered approach with any flap, the second a glide approach that starts 1000 ft abeam the landing line with any flap, the third is also a glide approach with no flap and the fourth is a powered approach over a 1.8 m barrier located 50 m from the landing line. The barrier proved to be the most challenging for most – even though the glideslope represents a normal landing state.



First up just after 10 am was the Unlimited Class, which were in 2 groups of 4 and thereafter Sportsman’s Class in 2 groups of 3. The officials were also trying out video recording for the first time (high speed camera settings) as video recording will be the planned standard for World competitions, which is at least an improvement over the ‘gatsometer’ system previously used.





When session 1 was completed, lunch was served after session 2 commenced at 1PM, this being the highest density altitude conditions with turbulence thrown in. A C182 turning downwind to final on the glide at best glide speed saw more than 1000ft per minute rate of descent, which did not leave much space to do the final runway heading line-up and arrest the descent to stabilize for the flare – needless to say the accuracy was not easily achievable to hit the landing line.

After all the landings were completed, the officials debriefed the scores and reviewed the video footage to ensure the exact touchdown points were scored. In the Unlimited Class and in first place was multiple SA landing and world champion holder Hans Schwebel in a C150 ZS-NBT. Fanie Scholz in a Sling ZU-FZF bagged the runner up sport while Jonty Esser in a C150 ZU-BLL took the final step on the podium.
