There is a formula for it but i will take it a different way. Jet and Prop jets have a high wing loading since they are all fuselage and no wing. They fly hot and fast and land the same way. if the engine quits in flight, there glide ratio is simliar to a lead balloon. Most Warbirds are the same way. You cannot just coast on in or you may stall it.
The lower the wing load number the more of a floater it is. My DC propjet has a wingloading of 32. I have a Large lanier Stinger with an 80inch wingspan with a wing load of 9. Size is really irrelevant. I have a "Shrike" have not bothered to figure it out but i bet it is in the 30's. I run out of elevator everytime I land
