Re: Why do most airlines lease aircraft instead of buying it?

Something else to consider is the benefit to some airlines during COVID - many were able to return aircraft coming off lease and made them the leasing companies problem, I know here in NZ, Air NZ was able to offload a number of 772 and 77W back to the leasing company, so they were not sitting on the...

Re: New Zealand Aviation Thread - February 2022

Out of interest why is NZ running cargo flights out of CHC and not AKL? One would think they would consolidate freight into AKL and go from there? I could be wrong here but this is my understanding. The government cargo scheme covers the movement of some goods internationally only. It's pretty comp...

Re: Why didn't the Boeing 707 have rudder problems similar to those of the Boeing 737?

Looking at cutaway drawings of the Boeing 707, it appears that this aircraft did not have split rudders like the Boeing 727 and that it had a single rudder actuator system. Of course cutaway drawings don't show everything. Since I don't have detailed schematics of the Boeing 707 and its civil and m...

Thinking about this, can someone possibly explain the ETOPS consequences of having the plane in storage for 1.5 years (not to mention no 777 ops forthe airline in that timeperiod)?

Re: Was [Is] it common to use only idle reverse thrust during landing runs in the DC-10 and L-1011 Tristar?

Most airports in the EU allow only idle reverse on any landing aircraft.

C-5 system is pretty simple set-up, slats and single-slot flaps. The Chug 14-1 didn’t have slats.

I never understood GLF’s lack of slats and using wing area to make up for ...

Re: A380 Reverse Thrust On Landing

Question, and a bit off topic, but would an airliner benefit from a split-rudder airbrake like the space shuttle had? Or would the complexity outweigh any benefits. The same could be said for the H-Stab.

Re: A380 Reverse Thrust On Landing

Interesting fact, Airbus originally wanted to certify it with no reverse at all! I believe the American regulators would have none of it and the compromise was on the inboards only, due to FOD risk given how far out the outboards hang (well over the grass at most airports) as per the previous post....

Re: Airline livery costs

Plus a more complex livery takes more man-hours to apply. The American livery is one of the worst offenders. With six different colors on the tail, it takes time for each color to dry, mask it off and spray the next color. I’ve always said that the American livery will be changed by the bean counte...

It's been a while since my last 763 flight and so am somewhat out of the loop with up-to-date heavy jet ops. After watching a series of A380 landings, I noticed only engines 2 & 3 seemed to use reverse after landing - some with idle reverse; some with full on reverse. https://fb.watch/aL9wmMdvX...

They’re happy using them domestically simply because there isn’t the demand to use them internationally.

If they are for domestic, will they also not have overwater equipment (rafts etc) like the ZK-OX... series?
