Embraer aircraft VS. Inclement weather
Do Embraer 190's and 175's have better landing capabilities in poor meteorological conditions? At YYT today during the storm that has been here the only planes landing are Embraer aircraft and Dash 8's. Just now AC2080, an Airbus A320 has diverted to Deer Lake. Yet an Embraer 190 managed to land from YHZ with no issues as AC2080 was still circling over Placentia Bay.

Runway 16/34 is the only open runway (the others NOTAM'd closed) and its length is only 7000'. Surface conditions show 20% ice and 10% compacted snow. That's probably not enough runway length for an A320 under those conditions. Embraers have a shorter landing distance. The Dash 8 has a much shorter landing distance.

Yes, the E90's have some form of GPS NAV, while the old A320s in the fleet are limited to VORs, NDB's, and ILS.
7000' is plenty for the 320. DH3 might have a lower decision height.
Don't know about the 767, there's some options to equip them with GPS, but not sure if AC has selected such option. The very early A320 builds that AC has are not upgradeable and AC operates some of the oldest A320s still flying.

Right, the E90s have LPV capability which most of the A320s do not have. But that wouldn't have been a factor at YYT if the ILS was functioning. 7000' is certainly plenty for an A320 with good surface conditions. With 20% ice and 10% compacted snow, the landing distance would be much higher and 7000' may not have been enough. Decision height for both aircraft is lower than the reported ceiling of 300'.

I believe all AC's 767s are GPS equipped for both enroute navigation and approaches.

Implies worst case scenario for the 320 is just short of 2500m. So that's plausible I guess.

Also, post 63 by YEGATC lists the fin as C-FTJP, fin 214. Built July 1991
AC flight 624 from Yyz crash landed at YHZ
Some technical discussion starts on page 16 of the thread
Edit ot add: see page 10 in the TSB report

I've demonstrated this a number of times in real-life and the accuracy of the GPS guidance with WAAS augmentation is astonishing.
