Planning to land on a wet rwy with dual (G+Y) hyd failure. (Sim time!)
From the QRH for msn 2500ish I came up with ALD (wet) 1360m with QRH wet landing correction factor of 2.15 to get LDR of 2924m.
For dry however the figures are ALD 1070m x dry landing correction factor 2.80, LDR = 2996m (3000m in QRH dual hyd fail summary) This doesn't really make sense to me.
Can someone explain or have I completely overlooked something??
