Often while the pilots are trained / educated are told to verbalize whether the runway lustry is

Or technical language - A landing is terminated (aborted landing / "go-around"). They can occur over time and to repeat. Yes, I agree that tend to induce stress and care being reserved lustry for passengers in aircraft than real need for it. Lets try to parse the problem:
Each landing runway must have in sight (the pilots). This means that pilots must either see the runway, you can see the runway or to be able to see / identify / recognize the lights that illuminate lustry it.
When the aircraft is at the final approach (final approach) landing / touch the runway during clouds, fog or rain there is some odd VIS (decision height) where the pilots are not allowed to descend o AT below the same unless they can meet the three requirements I mentioned earlier, the second type, when the runway environment in sight / in sight, at that point of approach to the runway the aircraft must be the altitude, direction and speed that will allow him to make safe landing (if you continue with the procedure for landing) and third type, pilots must have a stabilized approach - which means that the aircraft lustry is well directed and continues landing stable way. Side or rafalnite winds can cause the aircraft lustry to climb or descend to an altitude which is not in accordance with the prescribed procedures for access. Then, if stable access is not available to pilots, transition to stop O's Landing.
Often while the pilots are trained / educated are told to verbalize whether the runway lustry is "in sight" and that can perform a safe landing. As I stated above, even if one of the conditions is not met, disrupt lustry Otto landing is inevitable. In no time the aircraft is not allowed to find below some of th VIS odd (decision height) and the pilots then there remains no alternative but to stop trying to land and extension to what are called missed approach (missed approach ). Is that passengers see (inside lustry the aircraft) when they say "why not landed a runway passed?"
Missed approach is a series of directions, heights, or directions given to the pilot before landing and / or indicated in the tables (maps, maps) to access (all access diagrams during each access, whatever). Once the pilot for the decision to missed approach lustry if the traffic volume allows the pilot / pilots inform lustry air traffic control that go missed approach and both sides know exactly know where the aircraft will next focus on altitude and speed.
Every single instrumental approach published missed approach procedures; these procedures can be overridden by the air traffic controller if possible new procedures in force (that day / weekends). At the end of the failed approach of pilots lustry remains to choose to try the same airport again or to shift to an alternative airport flight different from that of their initial destination.
If you go to the airport the day with limited visibility or worse weather conditions will undoubtedly see many of these failed approaches. Unsuccessful approaches are not entirely routine, but they practiced and practiced and practiced by pilots (during training / education) until they reach the point where their response lustry is instinctive.
2 The next kind of missed lustry approach if the runway is not safe to land. The simplest example is when a flock of birds suddenly lustry decide to fly active runway. There may be many examples and reasons, it is very difficult to cross the missed approach, so any hint of failure for smoothly landing, it is always safer to go to a missed approach and wait for better conditions for landing. In almost all cases of unsafe landing runway (or the runway environment) pilots can only make short missed lustry approach procedure (granted by air traffic control) and quickly return for another landing.
Finally, one of the things inherent worry of whether travelers will have enough fuel for landing interrupted. International aviation regulations dictate lustry aircraft have enough fuel to reach their destination, plus enough fuel to reach an alternative airport (elected before takeoff), plus enough fuel for another 45 minutes flight.
