Pearson International : Visual Docking Guidance System
The last few times I have parked at CYYZ, more often than not I get a red arrow command to go left or to go right, even if the nosewheel is dead centre on the yellow line. If I follow the command and make the tiniest correction, usually this results in a command to turn in the opposite direction.
In a B777-300 with the nosewheel camera, I could see that I was definitely right on top of and centred on the yellow line. On a B777-200, I confirmed the same when I viewed the aircraft from the inside the terminal.
The B777 is a long airplane, especially the 300. Are the VDGS units at Pearson "fussier" than normal ? I have not observed this to be the case at other airports.
I don't ignore red commands for obvious reasons, but geez, either I am on the yellow line or I'm not.
Comments ?
