B737 Single Pack FL250
hi all, this one has really got me wondering...
case 1... a/c arrives with a pack problem, engg. releases a/c with single pack and mel complied with FL 250 Max Alt.
Case 2... same a/c takes off with no pack problem and just at ..say 5000 feet has a pack light and qrh says nothing about FL250, you conviniently climb your filed altiutude.
why did boeing penalise the airline for dispatching with 1 pack and no change for airborne non normal?
also is one pack is sufficient to pressurise the aircraft for almost all stages of flight, then why the restriction?
and if its really that important to have 2 packs all the time, then who NOT the restriction for inflight non normal?
would love to know how you feel about this...
