Weather

Live METAR & TAF from the FAA Aviation Weather Center. Raw codes shown alongside plain-text decode so you can learn to read what the pilots read. Defaults to airfields relevant to Fort Novosel Common Core students.

⚠ Not for flight planning. This is a training tool — always cross-check with 1800wxbrief.com, the AWC website, or a formal weather briefing before flight. Plain-text decodes are computed locally and may miss edge cases. Source: aviationweather.gov public JSON API.

Logbook

Personal flight log. Tracks aircraft, simulator, and CPT hours per entry. Data lives on this device only — export to JSON to back up or move to a new device. Not a substitute for your official ATM-201 record.

Pubs & Regs

Curated reference index for Common Core students. Each entry links to the authoritative source. Some Army pubs require CAC for the full PDF — armypubs.army.mil shows publication metadata even without CAC. Doc numbers and revisions change — always cross-check the live source before flight.

⚠ Currency Disclaimer

This index is a study aid, not an authoritative reference. Doc numbers and revisions change. Before citing any of these in a brief, checkride, or actual flight, verify the current version on armypubs.army.mil (Army), ecfr.gov (CFR), or your unit's publications library. Local SOPs always take precedence over the broader regs they implement. External links open in a new tab; CAC-restricted pages require a government-issued CAC reader plus matching certificates.
