777 Technical Question

[nrcrate 40]

Hey All,

 

I've been hunting for an answer to this for quite a while and have been unsuccessful... Probably since I don't know what exactly to call the thing I want to know about haha. It's just after 5:30 in the video below. On both the Captain and F/O side on the glareshield, outboard of the Master Warning/Caution lights. They look like black/white chevrons and they appear right after A/P disconnect. I'd like to know if anyone could educate me as to what exactly they are called and what their function is. I've only been able to find them in this one video, so I'm assuming they are a rare airline option. Thanks!

I am just guessing and can be way off... I think it was a full CAT 3 landing with rollout... My guess is the disconnection of the autopilot and rollout phase which caused the master caution indicator... Shot in the dark sure someone will correct me if I am wrong....

master caution indicator

Right, but I don't get a sense that those black and white barber-pool-like things are master caution indicators, especially since they move as they steer the aircraft off the runway.

It's Para-Visual Display

It's Para-Visual Display

Excellent! That's exactly what I wanted haha. Thanks!

 

Quoted from pages 159-160 in this document: http://www.asc.gov.tw/downfile/SQ006_ENG.pdf

 

...the PVD is a display that allows the pilot to receive directional information from a peripherally located display whilst maintaining eyes forward and out the window looking for familiar visual cues. The two PVD elements are mounted on the coaming centrally in front of each pilot; one on the right side and one on the left side... 

 

 

Each PVD unit is actually a mechanical device incorporating a rotating rod or pole that has black stripes on a white background (like a “barber pole”). Rotation of the pole gives the impression of lateral motion, or streaming, to the left or right. The PVD becomes a valuable indication in the case that runway visibility is poor (less than 50 meters) during takeoff. The PVD is tuned to the takeoff runway’s ILS signal. As long as the aircraft is on the runway centerline, the “barber pole” indication is stationary; however, when the aircraft diverges left or right of the centerline, the barber poles streams to guide the pilot’s steering. For example, if the aircraft is to the right of the centerline, the PVD will stream left to guide steering left toward the centerline.

 

The PVD is a high-reliability reversionary aid to runway steering—the primary aid being the pilot’s normal visual cues from runway marking and lights. The PVD should unshutter and begin functioning correctly as the aircraft is aligned with the runway centerline, and remain functioning as long as the controlling parameters remain valid. The PVD remains shuttered when it is not in use or when the ILS signal is not being picked up (e.g., out of range, signal blocked, system failure).

 

 

Hope that answers anyone else who wonders what it is.

will this be modelled?

EFB - I was wandering what the situation might be with regards to the EFB as i have noticed in captain sims 777 the EFB is modelled. I guess my question is will it be modelled and if so to what extent?
