Question for real world pilots on procedure for IFR clearance read-backs

I’m not sure, I think its nice “eye candy” but doesn’t necessarily contribute to safety. Airliners are required to carry a TAWS-B system (E-GPWS) with a terrain display feature. Only the way information is displayed varies, i.e. more fancy on a G1000 with synthetic vision. Having this installed might also cause people become dependent on it maybe.

When flying IFR and following procedures correctly, thoroughly prepare and brief, effective CRM and Threat and Error Management you won’t need something like that. Its more important to prevent ending up in such situations in the first place. I think its more of a help for non-professional pilots and VFR operations where routes and altitudes are closer to terrain and obstacles and based on the “see-and-avoid” principle.

I feel SVT will be extremely useful and a big contributor to SA specially around dangerous high elevation terrain, approaching through valleys and such. I do not see it as just “eye candy”. It is not a replacement for solid training of course but like HUDs & autopilots its just another tool. I do agree with the cost factor but lets see what the future brings.

Loss of SA in airliner flying is thankfully very rare (when was the last time we even heard about it on the news) but it does rear its head and overwhelms even professional crews.

See the examples below of old accidents. SVT in such situations like this would make a difference. The 757 was aimed right at a mountain.

American Airlines Flight 965

And this Airbus also hit a mountain in Nepal

Thai Airways International Flight 311

Both the above were airline crews, sometimes the brain becomes saturated with all SA lost and just seeing a big PFD with terrain accurately shown even in hard IMC or darkness could make the difference.
