  1. Far from it being my right to criticise a pro, but they work, are easy to spot when doing a pre-flight (when visible) and I presume when workshop work is being checked. Also, If a nut is properly torqued and fixed with a split pin, you know it is still tight. I suppose, like shoe laces, there are few higher-tech solutions that do the job as well...
  2. https://www.msn.com/en-za/money/politics/former-head-of-procurement-at-saa-technical-remains-defiant-about-dodgy-tender-dealings/ar-BBZRuai?li=BBqfP3n&ocid=ACERDHP17 And this is how is happened at SAA, Eskom, Prasa, Transnet, etc, etc. "Memela has confirmed that Lufthansa originally supplied the winning bid This decision was subsequently overturned due to concerns over “unrealistic low prices”, with the tender then awarded to Air France. The SAAT board proceeded to overturn the Air France decision and opt to award the tender to AAR and its local partner JM Aviation. SAAT’s Human previously told the Zondo Commission that JM Aviation has since been paid R53-million, but fulfilled “zero” of its contractual obligations. Human also estimated that SAA will end up paying R500-million more than budgeted for to AAR by the time the contract expires."
  3. That is sad. I enjoyed a few laps and a few beers
  4. I am keen on (finally) getting to the start of this one after a few mishaps on the way in earlier years. Is there anybody considering doing the relay but does not have a partner ? I have a (woman) friend who is keen on riding, but not the whole thing and would be happy to ride the second stage if she can find a rolleur to do the first. (Or she will do the first if someone wants to do the pass).
  5. Has anybody got a spare Mavic front skewer for a road bike ? Please.
  6. Coming from a pro, I take that as a compliment. It means I at least understood some aspects of "principles of flight" during my SPL days.
  7. No, not a hard landing. As Spokey has said, a fast one and he couldn't stop before the end of the runway. The damage was caused as he was still travelling at about 115kph when he got to the end of the runway and crashed into a wall further along. Spokey also spoke about the effect of a tailwind on stopping but let me try and answer the question differently and explain in layman's terms and very simplified, WHY this is so. There is a minimum airspeed for each aircraft below which the wing will stall and stop flying. Lots of things affect the stall speed, but for the purposes of this explanation consider it a constant. The landing speed of an aircraft takes the stall speed and adds a margin to that to ensure the plane flies all the way to the landing. Now, if there is zero wind and the plane moves through the air at 100kt, it is also moving over the ground at 100kt. If you are moving through the air at 100kt but you have a tailwind of 30kt you are moving across the ground at 130kt. Lekker when you are cruising: comfortable through the air, but fast to your destination. Conversely, if there is a 30kt headwind, and you maintain a airspeed of 100kt, you are travelling over the ground at only 70kt. i.e. Fast through the air, but nice and slow over the ground- which is what you want when you are landing. Remember, until it has landed the airplane does not care how fast it is moving over the ground, it is air moving over the wings that stops the wing stalling and keeps the plane aloft. However, once you are on the ground groundspeed becomes crucial as you want to be as slow as possible because you ultimately need to stop. Stopping a plane travelling at 130kt as opposed to 70kt is obviously a different proposition and therefore a plane typically lands into the wind because in addition to the lift provided by the plane's forward movement through the air, the wind moves more air over the wing allowing you to remain airborne but land at the lowest groundspeed.
  8. Landed very, very deep (something like 2/3 of the way down the runway), very fast with a tailwind gusting 30kt. Ran off the end still doing 63kt IIRC.
  9. Yip, .magnetic heading. More useless info for the day As the magnetic north pole moves, runways have on occasion had to be renamed.
  10. Thanks, I have sommer done this. It matches what I ride.
  11. Ja. That is the kind of scheme. Do you know how one signs up ?
  12. Basically, "prove it or F-off"
  13. Thanks. I thought as much. Bit silly if a 120km steady state ride is worth a third of a 60min 5 km Parkrun..... I seem to recall before when I was on Vitality that I got points for long, slow rides. Seems not anymore.
  14. I'm sure it ahs been covered before but as I am newly back on Vitality, I need advice. I get 300 points for a ride at >70% of max HR for an hour, but my typical morning road ride is 90 mins of which the first 25 or so minutes is level and downhill (Saxonwold, Rosebank, Dunkeld, down Bompas and Buckingham) before kicking up to take in Conrad, Norhcliff, Hill road, Wicklow and Jan Smuts. I end up with an ave HR of well over 70% for the last hour but because of the first 20-25 minutes, somewhere between 60 and 70 for the entire ride, giving me only 100 points. Short of starting my watch at the bottom of Conrad or breaking the ride in two separate activities, how does one deal with the fact that a ride may consist of a warm-up, effort piece and then cool down ?
  15. Gentle modification so that I could agree with your comments unreservedly.
  16. Whilst it remains the PIC's sole responsibility, of the CFIT cases I know details of, and I suspect in many more, it is not the pilot who has the "must get home" bug, but the alpha male plane owner/charter customer who is not used to being told "no" and insists he MUST get to his destination.. Unfortunately, some pilots don't have the authority to stand up to the main man...
  17. Read this old article written by a journalist who set out to answer that question: https://www.outsideonline.com/1924306/drug-test
  18. Will do so tonight. Direct descendant, as I had it.
  19. The plane that won the Battle of Britain accounting for 64% of all German kills, the Hawker Hurricane was built out of a wooden frame wrapped in Irish linen and painted with "dope". They could repair an air combat shell or bullet hole with a cloth patch whilst being refueled and rearmed and send it off again. A spitfire had to go to the sheet metal shop and be repaired by a trained artisan taking it out of action for days.
  20. Klaar gebraai. Nou gaan ek eet... Happy new year Hubbers. Trust you will all have a great 2020.

    Rapha Festive 500

    Some feedback after my third Festive 500 and advice to myself for next year. Only getting in 4h02 of riding in November and 3h10 in the first two weeks of December does not mean 500km in a week is out of the question. But rather do more in the run-up. It is good to get ahead of the run rate early on. A 100km or so on the 24th sets you up nicely. At the end of each ride, just stay on your bike for an extra 10km. It feels like nothing but can add up to 80km over the period. Taking a day off without riding makes the rest of the week more tricky. Next time I'll rather try and fit in a quick 25 or thirty km. They all add up. Taking both Christmas and Boxing day off as I did this year is silly. I won't do that again. Find someone to ride some of the rides with, but do a nice long one by yourself. They are different experiences. Go everywhere by bike. I needed a steak so rode to the butcher shop and went the long way round. The 40km helped to bring the outstanding miles down. If you have them, ride different bikes. It spreads the load on you equipment and your @rse.

    Rapha Festive 500

    Done. Plus a bit extra. Next year I will plan it more precisely..

    Rapha Festive 500

    Two quick laps of Suikerbosrand and you are there.....
  24. If they are going to bull****, at least they should use an argument that holds even a smidgeon of water vapour. How does my bicycle cause damage to the tar road from the Cape Point gate to the restaurant but my car does not ? Hopefully this incident forces the issue between Cape Tourism and Sanparks and we get a logical, pro-tourism solution. ps. I have no issue with paying to enter the park. I do so annually via my greencard.
  25. So if I am staying in Simonstown and drive in my car up to the top of Smitswinkel and turn left to go and buy a coke at the point restaurant, I can use my green card. But if I want to do the same trip on my road bike, I must first go to Tokai and buy a permit. It makes no sense.
