This study analyzes techniques instructor pilots (IPs) use to facilitate cr
ew analysis and evaluation of line-oriented flight training performance. We
analyzed IP facilitation and crew participation for 36 debriefing sessions
conducted at 5 U.S. airlines. For this analysis we developed a rating inst
rument termed the Debriefing Assessment Battery and demonstrated that it ca
n be used reliably. IF facilitation skill varied dramatically, suggesting a
need for concrete hands-on training in facilitation techniques. All measur
es of crew participation correlated significantly with IF effectiveness in
facilitation. Crews responded to IF guidance but did not lead their own deb
riefings. We suggest ways to improve debriefing effectiveness.
