Stop this "pilot hesitation" nonsense please! Did you really read the report? Here's the most interesting point:
"During that time, the aircraft was travelling in the general direction of the Halifax International Airport at a ground speed of more than 8 nautical miles (nm) per minute. From the actual descent start point, it would not have been possible for the pilots to position the aircraft for a landing on Runway 06, without some form of off-track manoeuvre to lose altitude and slow to
the appropriate speed. In a best-case scenario, the extra manoeuvring would have added two or three minutes to the landing time. More likely, a manoeuvre such as a 360-degree turn would have been necessary, or they would have had to switch to a different runway. Either choice would have added several minutes to the earliest possible landing time, and the effects of the fire would have negated the possibility of completing a safe landing.
At about 0125, when the fire condition became distinctly evident in the cockpit, the aircraft was about 25 nm from the airport, at an altitude of about 10 000 feet, and at an airspeed of about 320 knots. It was flying in a southerly direction, away from the airport. In optimum circumstances, from that point it would have taken a minimum of about six minutes to get to the
runway.
Theoretical calculations confirm that from any point along the actual flight path after the aircraft started to descend, it would not have been possible for the pilots to continue maintaining control of the aircraft for the amount of time necessary to reach the airport and complete a landing."
And to answer this statement from you :
"Yes you will find the requirements for approval for the IFE's, however that is the Canadian Report's veiw and requirements. Americans were on-board that flight and I am sure if this occured in the USA, a much different report would be filed as well as requirements for IFE's."
Here's the comment about the certification from the report, that clears up things in my opinion:
"4.3.8 Role of the FAA’s Aircraft Evaluation Group Title 49 United States Code section 44702(d) provides the FAA Administrator with the authority to delegate matters related to the examination, testing, and inspection necessary to issue certificates as part of its type certification process. The Administrator has determined that there exist certain aspects that are not to be delegated. One such function is the role of the FAA’s Aircraft Evaluation Group (AEG), which is responsible for providing operations and
maintenance input to all facets of the type certification process. For STCs, the FAA has determined that no delegate may make determinations regarding operations and maintenance issues; that role is reserved for the AEG.
For STC ST00236LA-D, the impact on the operations and maintenance of the MD-11 was determined by the STC applicant without direct AEG involvement. A survey of similar “non-essential, non-required” IFE system STCs revealed that approximately 10 per cent had been designed, installed, and certified in such a way that the flight crew could not remove electrical power from the IFE system without also interfering with essential aircraft systems. The
survey results indicate that the operational review conducted as part of the STC ST00236LA-D approval process, was not unique in not detecting operational shortfalls.
The Board is concerned that a de facto delegation of the AEG’s role has evolved with respect to the type certification process, which has resulted in less-than-adequate assessments of the operations and maintenance impact of some STCs, particularly those STCs designated as “non-essential, non-required.”"
So you really understood that the STC for the IFEN system was issued following the FAA process? How would that "different" report look like, what would it say? It's clear that the process of STC approval was clearly a contributing factor of this crash, and in my opinion the Canadian Report is clear enough stating this. I don't know if the FAA in the meantime changed the process, do you? Or does your statement imply, that the FAA corrects procedures only if they are mentioned in American reports?
Cheers, Thomas
