Narrative:
Phx has an approach to runway 25R which implies landing on runway 25R. At 3 mi tower may change the runway of landing to runway 25L. The procedure as written is potentially dangerous because of the phx tower workload and excessive radio xmissions by tower to clear aircraft for takeoff and landing on runways 25L&right. Tower easily gets inundated with radio communication and sometimes allows aircraft to penetrate the 3 mi final point without instructions for the aircraft on final to transition to wry 25L. For landing aircraft have been cleared onto runway 25R when landing aircraft are inside the 3 NM point for landing on runway 25R. The approaching aircraft is then required to abort the runway 25R landing then proceed to runway 25L or execute a go around. The visual approach procedure should be changed to allow the visual to runway 25L with clearance to land on runway 25L given in accordance with terps/aim procedures. Due to constantly changing WX and visibility problems at phx (ie, landing into sun during dusk hours and dust in the air which can reduce forward visibility to minimum standards), it is not prudent to establish an approach to one runway then changed to another in short final. Excessive radio communication and heavy traffic on these runways would appear to dictate a simpler approach and landing procedure be established. As this approach is written, it would be easy to see an accident where an aircraft on final to land on runway 25R would be missed and potentially land on an aircraft in position to depart runway 25R. Safety dictates that this approach be changed and simplified.
Original NASA ASRS Text
Title: ACR FLC CONCERNED WITH APPLICATION OF PHX POWER PLANT VISUAL RWY 25R NOISE ABATEMENT PROC AND BEING CHANGED TO RWY 25L AT OR INSIDE 3 MI.
Narrative: PHX HAS AN APCH TO RWY 25R WHICH IMPLIES LNDG ON RWY 25R. AT 3 MI TWR MAY CHANGE THE RWY OF LNDG TO RWY 25L. THE PROC AS WRITTEN IS POTENTIALLY DANGEROUS BECAUSE OF THE PHX TWR WORKLOAD AND EXCESSIVE RADIO XMISSIONS BY TWR TO CLR ACFT FOR TKOF AND LNDG ON RWYS 25L&R. TWR EASILY GETS INUNDATED WITH RADIO COM AND SOMETIMES ALLOWS ACFT TO PENETRATE THE 3 MI FINAL POINT WITHOUT INSTRUCTIONS FOR THE ACFT ON FINAL TO TRANSITION TO WRY 25L. FOR LNDG ACFT HAVE BEEN CLRED ONTO RWY 25R WHEN LNDG ACFT ARE INSIDE THE 3 NM POINT FOR LNDG ON RWY 25R. THE APCHING ACFT IS THEN REQUIRED TO ABORT THE RWY 25R LNDG THEN PROCEED TO RWY 25L OR EXECUTE A GAR. THE VISUAL APCH PROC SHOULD BE CHANGED TO ALLOW THE VISUAL TO RWY 25L WITH CLRNC TO LAND ON RWY 25L GIVEN IN ACCORDANCE WITH TERPS/AIM PROCS. DUE TO CONSTANTLY CHANGING WX AND VISIBILITY PROBS AT PHX (IE, LNDG INTO SUN DURING DUSK HRS AND DUST IN THE AIR WHICH CAN REDUCE FORWARD VISIBILITY TO MINIMUM STANDARDS), IT IS NOT PRUDENT TO ESTABLISH AN APCH TO ONE RWY THEN CHANGED TO ANOTHER IN SHORT FINAL. EXCESSIVE RADIO COM AND HVY TFC ON THESE RWYS WOULD APPEAR TO DICTATE A SIMPLER APCH AND LNDG PROC BE ESTABLISHED. AS THIS APCH IS WRITTEN, IT WOULD BE EASY TO SEE AN ACCIDENT WHERE AN ACFT ON FINAL TO LAND ON RWY 25R WOULD BE MISSED AND POTENTIALLY LAND ON AN ACFT IN POS TO DEPART RWY 25R. SAFETY DICTATES THAT THIS APCH BE CHANGED AND SIMPLIFIED.
