size means nothing in terms of performance....in fact, smaller can be worse.
Im more comfortable flying a GLEX or G550 off 4600ft before any citation, hawker, astra, westwind, Lear, or Falcon.
A GLEX has refs of around 105kts and landing distances of 2500ft when light, nevermind great TRS and autobrakes that will put you against your seatbelt on HIGH. you could use less then 2000ft easily if you tried.
Heck, my guess is you can go from that strip to London in a Glex or a 550.
of course snow, ice, winds, ramp surface, all play a part in deciding what to go into...but 4600ft is pretty easy, under most conditions, in bigger corp stuff like a 550 or GLEX
***just dont be afraid to use the bosses brakes***
