Back to Cape Town

About 2 and a bit years ago I took myself and my new(to me) Sling down to Cape Town. This was the last time I had been able to do a big cross country flight so I was quite pleased when the opportunity presented itself for another tax deductible flying trip to the Mother City.

The process of planning for such a flight (680nm) isn’t difficult – the main issue would be whether or not the weather would be conducive – fortunately late Feb/early March are good times to fly with the risk of thunderstorms having lowered and before the winter cold fronts start rolling in. With the full price commercial (easily refundable) tickets booked as backups, I was still pleased to see the weather looking clear for the flight down. The only wrinkle was the wind. Which was blowing. Like crazy.

The forecast called for the wind at FL85 to be 30kts on the nose and just getting worse above that, so I decided to flight plan at FL65 which is a LOT lower than I would like to fly. We (I was able to return a favor and give one of the chaps in the JLPC a lift down to Cape Town) decided to make an early start so we could fuel at Bloemfontein New Tempe (FATP) and still get in before it got too late.

Learning to land?

There are only three tricks to a perfect landing. Unfortunately, nobody knows what they are. It was in pursuit of these that I found myself 500ft over the threshold of Runway 36 at Brakpan Airfield (FABB), power off, flaps down and in an aggressive sideslip. Too low… damn it… 100ft up, still 1000ft short of the zero line, flaps up… nose up a little… not too much, she’s going to stall… better now.. hold it, hold it…. here’s the line, let her land (Windscreen fills with sky).. good – now full power, flaps 1 and off again.. Over the radio…“ZU-IBM, that was a +2, well done!”

Near misses and breakfasts

It’s been quite a long time since all 4 of us flew anywhere. Mostly this has been because of scheduling issues and the requirement that flying be limited to essential crew only (good grief – every single post seems to start with a COVID lockdown reference).

Groblersdal flying club hosted their annual breakfast flyin on Saturday so we decided to take a look. Initially it was going to only be my son and I but my daughter expressed interest and then my wife developed FOMO and suddenly the plane was full.

Racing again

After a successful navigation rally held some weeks ago the groundwork was laid for the resumption of Speed Rally flying. The season has been completely disrupted by the COVID pandemic with the second and third races being cancelled. There was much excitement when it seemed that we could continue with two further events this year.

And such it was that Steve and I found ourselves heading east on Friday afternoon to Secunda. Getting out to Rand Airport is a lot less of a schlep on a Friday afternoon than Baragwanath and the hangar attendant had pulled IBM to the front of the hangar so we were good to go – traffic levels at the airport are quite high and we were number 3 or 4 to depart for the short 70nm trip to Secunda (FASC).

Annual done and a new home

As much as May is a flying administration month with medicals and license renewals (did I mention it took 9 weeks to get my license renewal back from submission to collection?), August/September is annual time.

Last year I had a big shock in that I had to pony up for the 5yearly rubber hose replacement, so I was hoping for a less significant annual inspection this time round. Annual time is funny, because it forces one to take a look at the hourly cost of ownership of the aircraft for the previous year – and this obviously depends on the number of hours flown. So the denominator this year is much lower than last year because of the lockdown. Last annual year I flew 65hours. This year, 44…

Poker Run

The iconic SAAF birds on poles at Bara – Image Andre Venter (Flightline Weekly)

On the 15th of November, the Johannesburg Light Plane Club (JLPC) celebrated its centenary. This makes it one of the oldest flying clubs in the world. Aviation in South Africa has ebbed and flowed, but the club has been a going concern for 100 years which is no mean feat.

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.

Aircraft Ownership Maintenance

Annual time….

Ready and waiting for clear skies

As I write this, ZU-IBM is in for annual inspection. This should only have been done in October, but the CAA is a bit of a hot mess at the moment, and it is taking 3-4weeks to get the airworthy certificate or Authority to Fly (ATF) after annual inspection so we moved it up a month. I suspect this is mostly because the AMO doesn’t want airplanes stuck on its ramp waiting for paperwork to be completed.

I think it will help to have moved the annual forward away from the ATF expiry date because that should mean that we can do a full year on the next cycle. Anyhow, this does basically qualify as the first year of ownership and looking back, I must say that it has been really good to own the aircraft.

We’ve done a few trips that we would never have done, and the freedom of being able to decide on a whim to go flying is seriously under-rated. So here follows a small summary of the year in ownership..

  • Hours flown: – 69,5
  • Fuel purchased: – 1154
  • Average fuel Burn: – 16litres per hour
  • New Airports visited: – 17
  • Passengers Flown: – 37 (obviously not separate individuals)

Of course, there will be at least one unexpected expense involved and this time it is the 5 year rubber renewal which involves changing every rubber hose and gasket in the engine compartment. It is a bit of a pain and an unexpected expense which could be deferred… but that is not how I want to operate my aircraft. Deferred maintenance is something that I feel will bite one day and will be an issue if/when I sell the plane (yes, that RV-7 is still calling….).

There are a couple of other squawks that need dealing with – for some reason the starboard strobe has decided to call it a day, and the landing light wires seem to get quite hot coming out of the switch on the panel – this may well be normal but it needs to be checked out. The oil pressure still runs lower than I’m comfortable with on the long climbs – although we have looked at the system I think another once-over won’t go amiss. My gut feel is that the issue may be the sensor, but that is the easy way to rationalise it.

Apart from all that, the only other job is to put a decal on the rudder – I’ve long wanted the chequered pattern on the plane so we’re putting it on the whole of the rudder. I trust it will look good. The idea I have is what is shown below…

So, with no plane and hopefully no more surprises… there is little to do but to wait patiently impatiently for news on when Miss Daisy will be back. Will update as and when needed.

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.
