Taxiway inspections
I've just been watching an airport webcam, and the cars were out doing a runway inspection. Which made me think -- do they ever do formal taxiway inspections throughout the day for FOD etc too?
Obviously FOD on the runway poses a higher risk due to the speeds involved, and taxiway checks might be difficult to do, perhaps, in and amongst busy ground movements. But is it ever done, or do they just rely on everyone -- flight crew and all manner of airside staff -- keeping an eye out?
