| During the turn onto final leg, the first officer observed the PAPI and advised the captain that the aircraft was too low. |
| It was not evident whether the PAPI was positioned on the right or the left side of the runway. |
| When the captain saw that the PAPI was indicating that the altitude was too low, he initiated a missed approach. |
| In response to a query from the crew, the Bromont dispatcher indicated that the PAPI was on the right side of the runway. |
| The Bromont Airport dispatcher informed the crew that only the PAPI was operational. |
| At approximately 1000 feet asl and five miles from the threshold, the flight crew had the approach lights and the PAPI in sight. |
