So many questions, so few answers...
Yes, the ATSB report seems a little
thin on details.
1. A hard speed was put in the FMC. That speed was too slow for the HOLD they were eventually cleared for.
2. The monitoring of the HOLD entry and ALT capture was deficient.
3. The recovery from the low speed condition was not initially effective.
Why? There were three very experienced pilots onboard, so why indeed?
The only good to come from all this mud slinging is everyone here will be more vigilant in future when entering holding patterns. Not because they’re scared of the boss, because they don’t want to suffer the wrath of PPRuNe!
