There was a recent change by the FAA in aircraft weight & balance calculation. The average passenger weight for US carriers on ETOPS has gone up. Thus the new net passenger weight has made even a B737 NG
with winglets having problem in taking a full load from HNL
. Aloha experienced such issue just lately before they announced pulling out of YVR
route. Canada MOT
will follow the USA and put in similar rules, although carriers now on the route can still use existing Canadian averaging method. With a restricted loading B737-700 winglets version down to about 110 from 149, the route may not be profitable at all for Westjet. Even without weight restriction, a 149 configuration B737-700 NG
winglets would still need at least 78% load to break even, and when you are down to only 110-120, it would be near impossible to make money. There is no way a for Westjets current B737 NG
to reach Hawaii from YYC
even at current rules.
For Harmony Airways (HQ) using a B757-200 there would be no such weight restriction issue, although it have to carry less cargo. With the new weight regulation, HQ
's B757 can reach HNL
and not Maui without carrying any cargo. Maui is out because of runway length. With Aloha pulling out of YVR
, Harmony Airways will become the dominate carrier out of YVR
Why there is such a weight rule changes ? well, we are in a new century, and we the people just happened to 'grow' a little too much according to research results, especially female !!! (no offend to ladies, but that was what I was told by FAA). The FAA rules accordingly was based on accurate figures and they are quite sure of what they are doing.
