Plane questions

[edwardummer]

Hello,
I recently flew on a 777 and was wondering if any of you could answer some questions.

1. When we were coming down for landing the front portion of the wing (along the leading edge) kind of slid and rotated down a bit (not sure how to describe it). Does anyone know what this is? I was thinking it might be something to do with trim?

2. When taxiing along there are a bunch of signs next to the taxiway with numbers and letters on. I know some of the numbers and letters (eg 25R) are to do with runways but I was wondering what the others are for.

Thanks in advance!

Regarding the phenomenon of the leading edge of the wing sliding and rotating downwards during landing that you mentioned, this is usually due to the movement of the aircraft's flaps and ailerons during the landing phase. The 777 aircraft expands its flaps during landing to increase lift, and may also adjust its elevators to maintain balance and control. This action can keep the aircraft stable at low speeds, so it looks like the leading edge of the wing is sliding and rotating slightly downwards. This is related to balancing, as the captain needs to ensure that the aircraft maintains a suitable attitude and stability during landing.
Regarding the signs next to taxiways, these signs are usually runway identifiers for airports, used to guide pilots in the direction of taxiing. The combination of numbers and letters usually represents the name or number of the taxiway. For example, "25R" represents the taxiway corresponding to the right side of runway 25. In addition, there are other signs, such as "holding position signs," used to indicate when pilots should stop taxiing to prevent conflicts with aircraft taking off or landing. The combination of letters and numbers can help pilots find the correct taxiway and runway in complex airport environments.

For example, "25R" represents the taxiway corresponding to the right side of runway 25.

May I suggest you google “runway designator” and “parallel runways”?
