I'm assuming most of the contributers here fly for outfits with very junior F/O's. The F/O's in the company I work for average about 8000 hrs with many 1000's on heavy jets. If these guys are incapable of making such a simple judgment as when to reject then they should never get there commands anyway. After 13 yrs in the right seat of B737 or B744 are you going to wake up one day with a magical understanding of energy management.
Train your crews properly people. Allowing a PROFESSIONAL F/O to call the STOP is not reliquishing your command. On a long haul flight the Capt spends a 1/3 of it sleeping in the bunk whilst trusting his Snr F/O to make sound decisions in the event of ANY emergency.
I would like to see the stats on Stop/Go incidents and compare the two philosophies and see if there is any safety advantage of one over the other.
