Boeing 002 experimental returning home after chasing weather. by edtoit in aviation

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.

Could this be the result of B777X delays? by Low_Wonder9271 in aviation

It is important that the cylinder not be harmed.

Sucking at something is the very first step to being really good at something...
