As Fujii did not perceive, there are different rules around the world.
Fujii is wel aware of different rules around the world. All I said was that it is dangerous. If familiar with the Swiss cheese analogy, multiple landing clearances are just another hole. Although there is a perception that the landing pilot will see an aircraft on the runway, the pilot is far less likely to see a vehicle or personnel. The landing clearance is the controller’s cue for a final check. Approach path, runway, overshoot path, radar display, strip display and separation standard.
