Anti Skid and Nose Wheel Steering Switch questions
Hi,
I'm unfortunately not sure if I understood the full potential of this switch correctly. Hopefully someone can bring me nearer to this mystery.
From what I have read I understood the following.
If the switch is "on" the following applies:
- Anti Skid is activated
- Nose Wheel Steering is possible
- green hydraulic system is supplying the brake system (except parking brake which is always supplied by yellow system)
If the switch is "off" the following applies:
- Anti Skid is deactivated
- Nose Wheel Steering is deactivated (some airlines require this during pushback)
- yellow hydraulic system is supplying the brake system
I hope this is correct so far?
I have also understood that in a case of a failure in the green hydraulic system the normal braking system ceases to work and the yellow hydraulic system takes over.
When the pilot notices this on the yellow brake accu pressure indicator it is the correct procedure to let the brakes go, then flip the anti skid and nose wheel steering switch and then use the brakes again to stop the plane.
Is it correct that the plane looses its ability to steer the noseplane in this situtation?
Thanks for bringing some light into these things!
Best regards Andi
