slight meander to another thread, but DJ can operate 1:50 across the 737 fleet - exemptions were reissued by CASA 1 week prior to their expiry a few months ago.
The ratio renewals were "automatic" and did not review the Ops Manual which still has CC moving against pax flow to the overwing in a land evac. - contray to directives by Boeing, FAA and just about everyone else including CASA.
The new 20:16:3 NPRM will require a full safety case and ratios are determined by total number of seats not total pax.
Any increase in seat capacity under the new regime would require full review including evac demo and much closer scrutiny (i.e. opening and reading) of the Ops Manual by the regulator. The safety case also would require whole of duty/day of ops consideration of the CC which also includes fatigue/rest and inflight duties.
Must say that last time I sat in a chokkas DJ 700 I felt very uneasy about the thought of having to get out if it all went pear shaped.
