Narrative:
On several flts in yyz, we noticed a potential hazard to aircraft landing on runway 24L. Due to congestion at the gates, ramp control would hold an air carrier widebody transport on taxiway R1 facing northwest. The widebody transport exhaust was directed directly perpendicular to the T/D zone. This created significant turbulence for landing. Our medium large transport landed all right, but required greater than normal control inputs. 2 other aircraft complained about it. A commuter or aircraft could be dangerously affected, especially if the widebody transport advanced power to continue taxi. When this was pointed out to ground/ramp, they insisted there was no other place to hold the aircraft. However, it appears he could hold on taxiway right short of R1, allowing departing aircraft to taxi out R1 to 24L, or perhaps on the pad on taxiway B. There must be another way.
Original NASA ASRS Text
Title: A LNDG ACR MLG EXPERIENCES JET THRUST FROM ACR WDB WAITING FOR A GATE NEAR THE APCH END OF THE RWY.
Narrative: ON SEVERAL FLTS IN YYZ, WE NOTICED A POTENTIAL HAZARD TO ACFT LNDG ON RWY 24L. DUE TO CONGESTION AT THE GATES, RAMP CTL WOULD HOLD AN ACR WDB ON TXWY R1 FACING NW. THE WDB EXHAUST WAS DIRECTED DIRECTLY PERPENDICULAR TO THE T/D ZONE. THIS CREATED SIGNIFICANT TURB FOR LNDG. OUR MLG LANDED ALL RIGHT, BUT REQUIRED GREATER THAN NORMAL CTL INPUTS. 2 OTHER ACFT COMPLAINED ABOUT IT. A COMMUTER OR ACFT COULD BE DANGEROUSLY AFFECTED, ESPECIALLY IF THE WDB ADVANCED PWR TO CONTINUE TAXI. WHEN THIS WAS POINTED OUT TO GND/RAMP, THEY INSISTED THERE WAS NO OTHER PLACE TO HOLD THE ACFT. HOWEVER, IT APPEARS HE COULD HOLD ON TXWY R SHORT OF R1, ALLOWING DEPARTING ACFT TO TAXI OUT R1 TO 24L, OR PERHAPS ON THE PAD ON TXWY B. THERE MUST BE ANOTHER WAY.
