747 - 400 P & W 4056 Engines Burns
Could anyone give me a ballpark figure for an hourly burn for a Pratt powered 400 operating at MTOW?
Something along the lines of first hour burn then average mid cruise burn?

747-400 P&W 4056 "ballpark" figures
Top-of-climb at near MTOW =12,000kgs per hour
midpoint (say SIN-LHR) =9-10,000Kgs per hour
last stage of cruise = 8,000kgs per hour
These are approximate figures!
