As an example I think from memory and I may be wrong; the Lear 60 has the highest tyre pressure in civil use other than a B747-400ER ? and that would generally mean about a dozen or so airports in Australia would be suitable for a Lear 60. There is few of the type on the civil register and they seem to fly to aerodromes where PCN exemptions would be important...
Oddly enough, I think the RAAF do get it right in the VIP department. 5500nm range?
