Read an aircraft profile — B4 beta

Silent native app recording. Descriptive captions are editorial teaching text, not spoken narration.
The lesson retains source seconds 28–90 at normal speed; the overview retains seconds 28–60.
Setup footage and the extra closing hold are omitted. No agent output is replaced.

00:00:00.000–00:00:06.000 Let's ask a question we can check against a file.
00:00:06.000–00:00:12.000 A turn includes the work between our message and the answer.
00:00:12.000–00:00:18.000 Navlog reads the aircraft profile and checks memory.
00:00:18.000–00:00:25.000 Open the readDoc activity to see its arguments and result.
00:00:25.000–00:00:34.000 The profile specifies a Cessna 172N, 50 US gal usable fuel, and 2400 RPM.
00:00:34.000–00:00:40.000 Now ask a follow-up: what does the same file say about reserve fuel?
00:00:40.000–00:00:47.000 This is a second turn, with a new file read and memory lookup.
00:00:47.000–00:00:54.000 The answer arrives. Compare it with the returned profile.
00:00:54.000–00:01:02.000 Reserve: 45 min at planned cruise burn. The profile has no alternate-fuel entry.

Observed conversation

User: Read aircraft/c172n.md. What aircraft model, usable fuel, and cruise RPM does the profile specify? Cite the file. Keep this read-only: do not plan or file a flight, fetch weather, or change files.

Assistant: The profile lists: Cessna 172N (1978); usable fuel 50 US gal (long‑range tanks); cruise power 2400 RPM — source: aircraft/c172n.md.

User: Read the same aircraft profile again. Quote its reserve-fuel entry. Does it include an alternate-fuel entry? If not, say so. Keep this read-only.

Assistant: The profile’s reserve-fuel entry: "45 min at planned cruise burn" (source: aircraft/c172n.md). There is no alternate-fuel entry in the profile.
