Metro man
I suspect the Indonesians have downgraded the PCN for their own selfish reasons i.e so they can pick up traffic in SIN for LHR especially the higher yield traffic. When the loads and yield is viable it will be a nonstop to LHR.
I stand to be corrected so if anyone can tell me what the PCN at Soekarno Hatta is I can do the calculation. I would also need to know if the runway is regarded as flexible or rigid. The subgrade coding would be beneficial for further accuracy.
FWIW The B787-9 at a gross 245,847 kgs and a tyre pressure of 1,470 kpa has a greater PCN need than the B777-300ER at 352,441 kgs and a tyre pressure of 1,550 kpa on a flexible pavement.
