Climb Speeds Vary For 747; Why?

Thu Dec 05, 2002 12:35 am

Last evening I saw a PIA 742 doing a high speed climb en route to Jeddah, its a daily service and I have seen it uncountable times in many of which the climb has been so slow and loud, like the aircraft is straining to stay airborne, rather scary. So why was this plane going really fast?

Hi Airmale,

When you say you saw a PIA B742 doing a high speed climb to Jeddah, do you mean just after take-off?

Yes, it was less than five minutes into climbing.

I can't think of any significant difference in speed JUST after take-off. A heavier B747 will climb faster in terms of speed and at a lower rate of climb than a lighter B747.

Take off/climb speeds vary on all a/c for a number of reasons such as :-

take off weight of the aircraft, temperature, pressure, altitude of airport above sea level, weather, runway contamination, obstacles such as mountains/cranes etc, any restrictions on the a/c due to tech problems...the list goes on.
