A320 SR?

On several recent flights on Northwest A320s, I have noticed on the safety cards that the aircraft type is referred to as "A320 SR".

What is the meaning of the "SR" ?

I assume it´s the same as with the B747, Short-range=SR.

Is the "Overwater" designation a Boeing-specific one, and Airbus uses "SR" (Slide-Raft) to define aircraft configured with overwater safety equipment aboard, or is it something the airlines define?

Quoting NASBWI (Reply 4):
its SLIDE RAFT or OVER WATER

Which makes perfect sense... NW (now DL if you prefer) has a good number of routes (ie Mexico and the Caribbean especially) where requirements for such equipment are applicable, on which A320s seem to be the equipment of choice.

For whatever reason, "short range" didn't seem to fit the SR designation inasmuch as NW's A320s are used regularly on non-stop flights of 1,500 miles, give or take, and are capable of 2,000+ miles with typical payload at 100% load factor. Not what is typically seen as short range for a 148-seat narrowbody type.

As other users have said, it's "Slide / Raft"

Oddly enough, there are far more A320 SR's in the fleet than the 'standard' A320.

The regulations don't require Slide-Raft to fly over the Channel ... or from the UK to Spain

AF doesn't have any of its A318/19/20/21 equipped with Slide-Raft even though they fly them from CDG to North Africa (Tunisia/Algeria/Morocco) and to TLV, AMM, DAM.

While the (short) distance across the Channel probably explains the lack of the Slide-Raft requirement...

...do regulations require a somewhat indirect routing on UK to western Spain and Portugal routes for aircraft not Slide-Raft equipped, so as to limit the amount of overwater flight time/distance?

In the U.S., overwater regulations effect even NYC/BOS to Florida east coast flights, restricting aircraft not equipped to overwater specifications to a less direct routing close to/over land. Seems like UK to western Spain/Portugal would be a similar situation.

I've just had a look at LHR-LIS; if the European regulation is the same as what we have in the States, it appears that a small amount (<20 miles) of eastward deviation is necessary without rafts, but any routes to Spain are OK.

Thank you for finding and sharing this information. How are overwater regulations requiring rafts and crew certification calculated for U.S. airlines on shorter overwater sectors? ...such as NYC-MIA.

The quick and dirty answer is that if you are within 162 miles of shore, you don't need rafts (or the other overwater equipment). A straight shot NYC-MIA is just barely outside this; NYC-MCO isn't (though, depending on routing, not having overwater equipment could nevertheless be a disadvantage).

I too also though it was short-range, but no it is slide-raft.

That makes sense. It seems reasonable to assume that passengers cannot swim more than 162 miles.

The theory is that if you are within 162 miles of shore, you're pretty likely to be able to get back if, for instance, you lose an engine.

I wouldn't try to float with those seat cushions unless I didn't have much choice...
