After reading all this about automation of cockpits etc. and not looking out the big window in front, I ask m myself as an AGL Guy, why do we design and install PAPIs, Threshold Lights, Approach Lights, Runway Edge Lights and RWY Centre Line Lights if the Modern Pilots with all the smart stuff in their kit bags don't need them. Huge savings for the airport operator to leave them out.
But I suggest, there are a few fly boys out there who glance at these little luminaries from time to time, even if just to confirm that where they think they are is where they think they are.
