Because not all airplanes are equiped with the same instruments, and not all airport have the infrastructure and equipment to handle zero vision landings.

vehicle-land structures are reliable and risk-free and have been in use for some years. the 0-0 landing stated until now's a possibilty, as long as the two the pilots and the airplane are qualified to what's favourite as class 3c landing minimums. class 3 equipment and coaching is quite costly, and not usually used. think of spening $500,000 with a view to keep away from a 4 gour delay that should ensue 10 circumstances a 300 and sixty 5 days...it relatively is only not properly worth it. some airlines use it at places that fog in usually (Hawaii...additionally simply by fact there is relatively nowhere else to bypass if the climate drops on you enroute), besides the undeniable fact that it relatively is not very ordinary. the rationalization that pilots won't be in a position to land otherwise is with the aid of the fact if those structures at the instant are not put in, the pilots ought to confirm the runway and land the airplane themselves. And its relatively not ordinary to land on something you won't be in a position to confirm.

Despite all the technology that airports and pilots have at their disposal, it's still considered safer for the pilots and controllers to be able to see what is going on.
Not long ago there was a crash that killed over 300 people because a pilot tried to take off in fog, and neither he nor the controllers could see that there was another plane ahead of him on the runway.

Despite all the technology, the pilot still needs to see the runway to land. Modern instrumentation can guide the pilot in when the weather's bad, but if the ceiling (cloud cover) is too low to the ground, the pilot can't see the runway in time to adjust and make a safe landing.
Hope this helps!

There is one exception - Alaska Airlines (AS) is equipped with special equipment to land in low visibility conditions, particularly at Anchorage. In fact, they love the trumpet the fact that when the Olympic torch was heading to Alaska and the original flight was canceled due to weather, the Olympic committee called AS for arrangements.
Oh, and part if the answer isn't lack of equipment, it's the distance of separation mandated by the FAA in low-vis flying, and if it was dense enough, LAX's parallel runways could be reduced to 50% capacity.
This happens all the time at SFO - the parallel runways were built too close together, and even in just low-ceiling conditions require the closing of one of those runways.

If there is no visibility, the pilots can't see the runway. Also, pilots are rated differently. Some can land in certain conditions, some can't.

Technically, they could land "hands free". But with so many lives at stake, they won't rely solely on a computer. Has your computer ever crashed?
