Jmk – 34/16 Mykonos | Greece Lgmk
Umm - 63.2t is the limit I think for an A320 on PCN 34 and B subgrade. And the 10% buffer is not recognized internationally for PCN - that might be an old LCN concession.
JMK = 34/F/B/X/U
F = flexible = asphalt
B = subgrade strength
X = medium pressure tyres < 1500 kPa
U = Using aircraft experience: representing knowledge of the specific type and mass of aircraft satisfactorily being supported under regular use.
A320-100 77t
PCN = 42. Tyres= 1450 kPa. Quite a bit over the pavement weight limit and a formal pavement concession is needed. The overload is 42/34 = 24%. It appears that others are using A320s there. Tyre pressure within limit and no concession needed for tyres.
To get the concession, I suggest you read your local Sunday paper for articles about how business is done in Greece.
