And sometimes people just get things wrong. And even professional pilots are people.š
Thankfully it doesnāt happen often. Although the old Kai Tek airport at Hong Kong did have quite a few. Having flown in there as passenger on several occasions I could see how even a fully alert, wide awake crew could get a little stressed, let alone those that have already been working for 12 or more hours.

This is happening already.

Unfortunately that is not how it works. Aviation is treated as one big cake by the insurers so every accident, no matter if itās a C172 or a 747 has an impact on premiums for everyone. Seeing how GA premiums have skyrocketed and, particularly in the US, insurance is denied to people on shady grounds, getting insurance may end up being one big problem for all of aviation in the mid term.
I once saw an operator change acceleration altitude from 1500ft to 1000ft as it saves an estimated 17kg of fuel for each flight
I am sure they forgot about reverse tailwind gradient? this should keep beancounters busy for few weeks

I think itās because of scale. Each department gets these KPIās and goes crazy about them. Thereās apps that show you your fuel burn on a certain sector compared to everybody else. Itās subtle pressure and imho itās going in the wrong direction, will cause some trouble ahead and then there will be a push in the other direction, negating it after all.

Sounds ridiculous when youāre burning 130 tons on a single leg, at least it did to me. Beancounters then explain that e.g. for 1000 take offs a day, it will save many many millions over 50 years. I just thought āthink of how much fuel we could save if we donāt fly at allā, wellā¦

Of course, like any cost is transferred to end customers. Thereās no other way in any business

I asked myself the same but then realized that accidents were covered by insurance. So for the company probably nothing is lost, maybe slightly increased insurance premium next time.

These guys work very hard, always through the night, often hanging around airports in between while sorting/loading goes on. Then thereās tons of cost saving measures by the .xls crowd
- use idle reverse to save fuel (money)/ less noise*
- use autobrake low to save brakes (money)*
- vacate at high speed exit (at the end) to save tyres (money)*
- fly low drag approach to save fuel (money)*
- 60 emails a year about āuplift minimum block fuel (no āunnecessaryā extra fuel (money), P L E A S E ! ! !)ā*
- 7 items āMELādā on hold items list, affecting 19 different combinations / subchapters in the manualā¦ one brake deactivated, one TR deactivated, performance penalty 2300kg, ātake fuel but be aware weāll have to leave payload behind, Captainā ā but itās all legal*
- oops, the plane was 3 tons heavier, some containers were erroneously swapped shortly before departure*
* unless required/not possible for safety reasons
* Delay reason: commander requested reweighing of all cargo prior departure due to prior inconsistencies experienced at this station
Thereās rules, and thereās getting the job done. Not saying this has anything to do with this particular excursion, but 737 brakes are crappy, these guys are always under time pressure flying old junky planes while unimaginably tired.
