Yes it is. The controls check is not an annoying "paperwork" thing that has to be got out of the way as quickly as possible before take-off, it is a vital and absolutely essential check.
We absolutely MUST know that all the computers, hydraulics, flight control surfaces, feed-backs and SD page are moving correctly and in the correct sense before taking to the air.
Some pilots like to say, (or think): "it flew in, it will fly out....." NO ! Not necessarily. It's not mechanical anymore. The 5 computers and the three hydraulic systems will all have been off-line during the engine shut-down on the stand, and there will have been up to 6 changes of electrical power source from taxying in to taking off.
So it is extremely important to perform the control check diligently to ensure that all those many components and systems have come back on line correctly after engine start and all those power source changes.
Let's be careful out there.
