No Reverse Thrust Landings

Sat Jun 27, 2020 6:34 pm

I’ve landed at Toronto on an AC 763 and today SLC on a 753 and both were nearly silent. I was in the back for both but still. Maybe it was just low RT? Do these airports have noise restrictions/protocols?

Reverse thrust is usually more expensive than brakes. So most airlines policy is to select reverse idle, and use the brakes.

Our policy is to ALWAYS use reverse thrust. And it has to be selected no later that 2 seconds after touchdown. Any later that that (or no reverse) and you have to file paperwork. No punishment just an air safety report explaining why. Idle reverse is the minimum and no minimum duration. This should be discussed in the descent briefing and changes mentioned on final approach if wind/runway conditions reported by tower are different. No reverse or late (>2 sec) reverse is one of our key safety indicators that is actively monitored by the governing civil aviation body.

Could be a couple of reasons. Light load, operational policy, pilot option, one reverser is deferred and don't want the yaw, etc. Could be that you just missed it. I remember not using reverse thrust on a flight into PMD (or brakes for that matter) and having 2 passengers ask me about it. It was a super long runway and wasn't needed as the terminal was at the far end.

YYZ does have the comment in their noise abatement procedures.....”consistent with safe operating procedures, plan landing with idle reverse thrust”

My guess is they did use reverse, but it was idle reverse. This fine even with "minimise reverser use" noise regulations. All idle reverse does is open the doors so there is no noise beyond the normal engine idle noise...

We always use idle reverse. That way full reverse is available quickly if you need it. Full reverse is used when necessary for the operation, e.g. wet or contaminated runway, short distance to desired exit, etc...
