GOL 737-700, Call Sign GOL Questions

Tue Oct 20, 2009 8:44 am

Hi all,

did a stint with GOL yesterday, a 737-700.

The following questions came up for you guys:

What are these 8 little edges please.....indicated by the red arrow.

Big version: Width: 1600 Height: 1200 File size: 343kb



Not many planes have the call sign identical to the owner´s name.........this one does!
But isn´t this illegal.......not showing the complete call sign?
It says PR.......while it´s PR-GOL.

The yellow arrow shows the inboard spoiler........
This one was only deployed after landing.
But as the picture shows, other spoilers were used various times during flight:

Big version: Width: 829 Height: 1210 File size: 211kb


Why please?

Cheers,

Chucha M.

The eight little strips are vortex generators I believe, and the inner spoiler is a ground spoiler (i.e deploys only on the ground)

I'm afraid I do not understand your second question. Perhaps you could rephrase it?

If you notice, the "PR-" has a dash (-) after it. I'd be willing to bet that the other three letters of the registration are on the other wing.

Certainly can!

Why are the other spoilers deployed in the air at times?
We were not that close to landing or anything..........if you take the power off you get the speed you require, correct?

So the sub-question would be "why is the ground spoiler for ground use only"?
Obviously not only because of the name, I´m after a technical explanation why, if you could. Thanks.........

Very possible...........but I always thought that the full call sign had to be on top of 1 wing and on the bottom on the other side.

Cheers folks,

Not the call sign, but the aircraft registration. if it was the call sign, it would have to be repainted every flight!

Might have been an ATC request for them to slow down for spacing. The 737, if I'm not mistaken, has a reputation for being a tough aircraft to slow down as well due to it's apparently clean design. I'll know more when I start sim training soon, but WILCO will probably answer this in the meantime.
