At the pointy end,in our job as energy managers,this falls under category 3,after managing energy of aircraft,and the energy of the crew.It manages the energy of the passengers.
If we come to an RTO abrupt stop,the pax are going to be full of it(energy),and its unlikely to be positive!. They will immediately look to the cabin staff for answers.
If the cabin staff stay seated in their takeoff positions,looking concerned,this could easily add to the already negative energy level amongst the pax.
However,if the pax see the cabin staff instantly responding to the calming words of Captain Roger Moore,"Cabin attendants to your stations",..and watch as they (cabin staff)check the conditions outside their responsible exits,this will add some positive energy back to the situation.
The pax will be aware that something is being done for them,and may prevent them taking things into their own hands!
Its all about the energy..ain't it!
