Being a bit of a sad person at times and a great fan of Air New Zealand flying LHR
I did produce a spreadsheet once to investigate the operation that showed:
route required 3 aircraft
route required 4 aircraft
3. I allowed 2 hours at each port of call.
4. All times were based on 744 performance for flying each segment.
Interesting enough because the A346 is slower that the B744 the 1. route would (just) require an additional aircraft (if regular scheduled times are desired). If Air NZ
did Bangkok instead then 3 aircraft could be used again!
I can't quite remember but I think the LHR
route arrived at Auckland at some early hour in the morning (2/3ish if memory server). I didn't think this was very desirable so the current scheduled times from AKL
might need tweaking to make arrival occur at a decent hour. I not even sure if AKL
allows night flights?
The life of an operations planner must be a challenging one to juggle so many variables, to arrive at optimal efficient use of the aircraft.
It has to be said that this is probably not the case at the moment at LHR
, because the turnaround between NZ2 arriving and NZ1 returning is 6 hours - along time to have an aircraft on the deck. You could be half way to HKG
in that time !!!
