responders on the airport property. some of that we have already talked about yesterday. i have seen and heard some report about a 4,000-foot per minu minute descent rate. the group that reviewed the initial data have indicated that there s no be a normally feet descent that has been defetecte in the data that they have. hour power plant team has conducted an on scene visual of the engines. the primary evaluations indicate both engines were production power at the time of impact. and this is consistent with information that we also see on
the aircraft. quick access recorder or qar, it may record different parameters. so we will also take a look at that as well. we have a vehicle performance group and they are focused on t the performance. it f it performed in a way that was predictable and consistent with the manufacturers guidance and expectations. there are ground marks, witness marks and significant amount of evidence on the airport property. they are also evaluating and reviewing videos made available us to by the airport and by others. the performance group will use
presicision approach path light available to the crew but on 28 left those were significantly damaged in the crash sequence and so after the crash the asiana aircraft, they were put in a list that the lights on 28 left are out of service. that occurred postcrash. they ll be looking at all of the approach lights. they ll be documenting the runway markings, lighting and conditions and then evaluating construction activities taking place on the airport property. we are looking at emergency response. this is the postcrash response. our deployed or aircraft rescue and fire fighting operations deployed 29 responders in 9
you do not need instruments to get in to the airport. again, it was a clear day, good visibility. they were cleared for a visual approach. so we do have a piece of equipment, a glide slope that s out. we have to evaluate whether or not the pilot s used or had available to them other tools in the aircraft or outside of the aircraft that were on the airport property and how they were flying the approach. whether they were using automation. whether they were hand flying. that s information that we have yet to determine and so i would discourage anyone from drawing any conclusions at this point. we will be back. we will provide more factual information. i thank you all for your efforts to get it right. have a good day. what time? okay. that is deborah hersman, the chairwoman was the national transportation safety board holding a press conference at
that were available to the crew. however, on run way 28 left those were significantly damaged in the crash sequence. and so after the crash the as n asiana aircraft those were put in a notice to air men that the lights were out of service. that occurred post crash. they will be looking at all of the approach lights. they will be documenting the run way markings, lighting and conditions. they will be evaluating construction activities taking place on the airport property. we are looking at emergency response. this is the post crash response. our deployed or the airport rescue and fire fighting operations deployed 23 responders and nine vehicles after the crash.
