YSCB RW 17/35 PCN35FBYU
B747-400 ACN60
I don't know what the basic weight is of Air Force 1 but probably not much different from a commercial 747-400. Landing weight at YSCB would depend on landing fuel and POB and I would guess it would land at a relatively low weight.
The Boeing pavement Strength Overload Guidance states:
For normal operations, pavement limitations can usually be exceeded by 5 to 10% without any appreciable impact on pavement life. For low frequency operations, overloads in the order of 10 to 25% are acceptable, however the pavement should be in good condition, otherwise near term deterioation may be initiated by the overload. For emergency situations, a 50 to 100% overload allowance is generally accepted, subject to the discretion of the airport involved.
Where did Air Force 1 originate from before landing at YSCB? What tyre pressures did they use for the YSCB landing? Couldn't have done too much damage if it took the airport operator three years to complain about it.
