Morning all.

Quick question - I know that, due to the shorter fueslage, the 747SP's vertical tail and rudder are enlarged (to make up for the shorter moment arm).

Is the same true of the horizontal surfaces?

As far as I know it is, from what I've seen anyway.

The top of the tail looks like it's smaller so does this mean that the 747SP's emmenage consists of a normal 747 tail fin with an extension of some sort on top?

Both the fin and tailplane are extended / increased in area to counter the shorter moment arm.

Thank you, folks. Made sense that it would be bigger but I couldn't really tell.

Yes.

The rudder is also double hinged to give more deflection. If you look carefully you can see the split in the middle of the rudder.

I think they have done the same to the LCF
