A300 Vs. A310 Tailfin

Wed Jun 15, 2011 4:46 pm

Is it true that the tailfin of the A310 is slightly lower than on the A300, roughly 50 cms? The only source about it I found is wikipedia, and photo comparisons seem to confirm it, as do the factory figures for the whole plane heights.
Its interesting that the shorter plane has a lower tailfin, on the A330-200 vs A330-300 its the opposite.

The vertical stabiliser height on the A300 and A310 is the same at 8.3 m.

What you are seeing is just different gear heights, weights, and CG position, and the effect of a longer fuselage.

Best way for me to illustrate this giving you the heights to the forward and aft cargo bays.

Height of forward cargo floor above ground (Empty/Maximum Ramp Weight forward CG//Maximum Ramp Weight aft CG)
A300 - 2.73/2.55/2.68
A310 - 2.62/2.48/2.58

Height of aft cargo floor above ground (Empty/Maximum Ramp Weight forward CG//Maximum Ramp Weight aft CG)
A300 - 3.09/3.01/2.92
A310 - 2.70/2.60/2.55

Thank you. I only wonder why should wikipedia say that the tailfin of the A310 was shortened in comparison to the A310 if there is no reason behind it?
The A310 has a height of 15,80 m vs. 16,53/16,62 of the A300. I know the fuselage isnt even when the ac are standing, but could this really account to a height difference of almost 80cms?

You are confusing two things here, wiki says "Smaller horizontal tail surface", not vertical. The horizontal stabiliser on the A300 is 16.94 m wide, and the A310 16.26 m wide. The vertical stabiliser is 8.4m

Yes. also the A300 is longer.
