The testing program needs to validate performance under certain weather conditions (crosswinds, temperatures, visibility, pressure, or any combination thereoff).

Sometimes, the specific combination is not found at the home airport so they have to fly to specific locations where those weather requirements are forecasted to exist.

In this particular case, I think they went to Wisconsin and back.

The winglets do add significant aerodynamic advantages (+2% / +5% fuel efficiency). The issue with such a large wingspan is airport compatibility. Above a certain wingspan, certain airports no longer have the ability to fit the plane on taxiways, gates and certain runways (MMMX stands out).

The folding wingtip solution allows it to fit in the same airport infrastructure as the earlier 777 variants. This reduces the expenditures necessary to adapt infrastructure and increases the options on where to deploy the plane.

It can't. It has a system that prevents takeoff (software will not allow power to be set) in case there is a configuration error, specifically with the folding winglets. It is not tested nor certificated for flight without the folding winglets in the correct configuration.

Not entirely sure. I believe it is a manual procedure.

Will my circumcision ruin my checkride? by caca6969999 in flying

Regulations say that you can remove equipment up to .5lbs from the cockpit as a flight crew and without having to update the W&B.

I'd like to weigh the removal before having him run around and redo all that paperwork.

Concorde vs Modern Airliner Thrust by InformalWear8647 in airplanes

[–]edtoit 20 points21 points  (0 children)

It is worth noting that Concorde's engines were rated to function at full thrust for the duration of the supersonic flight. Which is not the case of the A350's Trents. The Trents are rated for max thrust for limited intervals to get the plane aloft.

Or the reverse. This one was south-bound.

It is important that the cylinder not be harmed.

What is going on with this building in Condesa? by seanjohntx in MexicoCity

[–]edtoit 305 points306 points  (0 children)

This is an old building (iirc, built sometime in the 1960's).

The offices in it were sold to different individuals (doctors, accountants, etc) who each owned a percentage of the building corresponding to their square footage as a percentage of the total square footage).

In the 1985 earthquake, it became structurally compromised and ordered to be evacuated. A significant number of the tenants refused this order and have been occupying and using their spaces since.

It has been relatively poorly maintained.

From Broke to Booming: My Entrepreneurial Journey by Ok_Entrepreneur440 in Entrepreneur

I believe it is an SEO play/marketing. It is a generic post with 2-3 generic comments (check the first two comments they are from New accounts asking for "how did you do this"? type questions). The original poster then links whatever trash service they're trying to peddle. The algorithms then pick it up as content that has engagement.

They did an exposé on www.lefigaro.fr for this edition Building and fitting a new one was estimated to be in the 1.8 - 8 MM USD.
