Something I noticed on the flight to Holland...

I was fortunate enough to get a window overlooking the wing, and I noticed when the bird was turning, that the crew use spoiler input in addition to aileron input. Was anyone else aware of this? I just think it's interesting. Also, I noticed that the crew made spoiler checks while taxiing.

Well, operational checks of all control surfaces are undertaken before every flight. You'll find that due to time constraints, most of these checks take place during taxi to the runway.
Perhaps this is a deduced method of countering adverse yaw used for this size of aircraft during slow manouevering. These are known as differential ailerons. Just an idea. But to be honest, firstly you need to know what type of aircraft, what control surfaces it has use of.

Assuming Hammer referred to turning in the air and not on the ground, there are several aircraft that supplement ailerons with spoilers for turns. It is usually NOT a pilot selected option.

On the other hand, deployment of spoilers on both sides to aid in landing during and through the touchdown is sometimes pilot operated and at other times the pilot arms them before landing and after touchdown they auto deploy.

IIRC, the Mitsubishi MU-2 uses spoilers as the primary roll control.

As does the MU-300 (Mitsubishi Diamond Jet) aka BE-400 (Beachjet) aka T-1 (Jayhawk) aka Hawker 400XP.

Good one Madrus!!! I never realized that the MU-2 was spoileron control only.

This was turning while in the air, and the bird was a Boeing 737-800.

So generally, very unlike a MU 300 or BE 400, but infact very much like any typical airliner you might travel overseas on, right?! :roll:
