Aujourd'hui j'aimerais amener sur la table la discussion suivante :
Thème : Seat Selection vs Safety in eg A321 (3+3) cabins :
Airbus and Boeing are obliged to perform evacuation exercises when applying for the Airworthiness Certificate for a new type aircraft. The criterion is a demonstrated total cabin evacuation in less than 90 seconds, through 50 % of the available emergency exits. This is a HUSH-HUSH event, "off limits", "in-camera" (huis clos), no unauthorised personnel witnessing these events.
Try to get a ticket to witness and tape for your Bloggers or Readers one such event if you are a Journalist and you'll understand. Only FlightGlobal's Group Editor-in-Chief Kieran Daly has been granted this "privilege" having volunteered himself for the escape drill : http://www.flightglobal.com/articles/2006/03/27/205638/airbus-a380-evacuation-test-flight-exclusive-from-onboard-the.html
Drill performers are selected from professional sports teams : trained hand-ballers, athletes... They are given numbered dossards corresponding to each individual seat where the performer was seated BEFORE the evacuation exercise started. The flow of exiting performers through each of the Overwing, Forward Left and Aft Left doors down the escape slide shutes is video taped. Paramedics and fully equipped mobile medical surgery units are available ready on the spot. Eg, at the Certification escape test for the A380 there was ONE BROKEN LEG, plus a total 32 other people with minor injuries, as is reported by Kieran Daly.
What I'm driving at is this : for the (3+3) single aisle 737 or A320 types, take say, A321, with 2x4 available emergency exits, whereof 2x2 located overwing, in average, out of the LAST NINE PERSONS ESCAPING (through 4 of the 8 exits, ie, out of the last 4x9=36 persons escaping), SEVEN (times 4 = 28), or 78 % are retraceable (from their dossard numbers) as originating from seats "A" or "F", ie from an OUTER SEAT (LHS or RHS) in certain groups of triples. The further away from the Emergency Exits, the later they evacuated.
Meaning this : in a typical all-Y 32" pitch A321 cabin (3+3) with 31 rows (186 seats) the groups of seats in rows 21-25 in the aft cabin, plus the groups of seats in rows 7-11 in the forward cabin, are the DEATH SEATS, plus all of seats 5A+5F, 6A+6F ... 13A+13F fwd and 20A+20F, 21A+21F, ... 27A+27F aft are the SUPER DEATH SEATS : if you are seated here and FIRE is on, you'll be evacuating the cabin amongst the last, ie the chances to escape the toxic smokes is greatly impaired vs other seats.
I'm presently campaigning in favour of an OBLIGATION OF INFORMATION by Operators to Travelling Customers : in the BOOKING process, if the traveller is selecting a "death seat" or a "super death seat", he or she has the RIGHT TO KNOW that his or her SAFETY is IMPAIRED. An automatic - compulsory, by FAA/EASA regulations - WARNING should pop up with a tick to be introduced from the screen by the traveller in the seat reservation process, confirming his or her full awareness and acceptance of the impaired safety situation.
I have contacted top management @ EASA in Europe, and the Rule-Making Office @ FAA in the USA. I'm also active with Consumer Unions, like BEUC in Brussels, or safety advisors like Candace Kolander @ AFA-CWA. What I'm looking for are ways to DRUM UP THE MESSAGE : the choice of seat in a (3+3) SMR Feeder aircraft such as eg 737NG-900 or A321 is not neutral in terms of physical safety.
An easy and immediately effective way to do away with this embarrassing situation would be for FAA or EASA Rulemakers to introduce a rewording to FAR Part25 Section 817 ( http://www.asa2fly.com/files/updates/Part25.pdf, look up Page 85) the new preferred wording to read as follows : "no seat may be installed in an aircraft cabin more than maximum one seat away from an aisle".
This would prohibit Operators to install triple seats squeezed against a wall-panel in aircraft cabins, which is uncomfortable for Passengers, inergonomic for Flight Attendants and Cabin Cleaners, and unsafe (based on the foregoing).
J'invite mes Co-bloggers à discuter de cette question...
