I just have to give my 5 cents worth in this debate... I stand corrected (haven't flown a Van for about 7 years, great airplane none the less), the tyres are rated to 180kts. I think the operators have got a great concept going with flying out of ORTIA to the Lowveld, it save foreign travellers a lot of time and money transferring to smaller GA airports, giving them a better, SAFER experience and it leaves a little extra of their travel money over to spend in our country, which, at the end of the day benefits us whether we fly heavies or C172's...
I fly turboprops out of ORTIA for a scheduled airline, we also get shoved around the airspace to accomadate the jets that wish they could fly 250 KIAS to 6.5 NM and still be in the slot at 500ft to touchdown.
My point is there IS enough space for all of us and here and there we ALL have to compromise, we all have a job to do so let's help eachother out. Do you want our airspace to become like our roads??? I don't....
