Procedures and charts

Chart Supplement

Charts open from the FAA's digital Terminal Procedures Publication, cycle 2612, effective 11/26/2026 12:00:00 AM to 12/24/2026 12:00:00 AM. Not for navigation; check the cycle before flight.

NOTAMs

Not for operational use

NOTAMs as captured by CircumFlight from the FAA's NOTAM distribution; not FAA data, and not necessarily complete or current. Always get an official briefing before flight.

PLAIN-LANGUAGE READING - BEST EFFORT. Abbreviations are expanded automatically and may be wrong or incomplete. The raw NOTAM above is the official text; fly by it, not by this.

Release queue

Awaiting release

No departures are waiting on a release time right now.

Recently released

No recent releases in the current picture.

Release times (the slot at the departure fix) and delay causes from traffic management, derived by CircumFlight, as of 2105Z; not FAA data and not for operational use. Get your release from ATC. Aircraft whose owners have asked the FAA to limit the display of their flights are not shown.

Arrivals and departures

Arrivals

No inbound flights in the current picture.

Departures

No outbound flights in the current picture.

Flights seen in the last five minutes, as of 2105Z. A departure at a gate has its departure clearance and has not yet moved; a place marked (est.) is the nearest stand to the aircraft's last surface position. Derived by CircumFlight from air traffic management feeds; not FAA data and not for operational use. Times are estimates from distance and ground speed. Aircraft whose owners have asked the FAA to limit the display of their flights are not shown.

Statistics

Grants

No FAA airport grant to 21N is recorded for FY2010–FY2025. Awards to a state's block program or a system plan are not listed by airport.

From the FAA's Airport Improvement Program grant history reports, FY2010–FY2025 (federal fiscal years, October to September), as the FAA published them. Every program in those reports is counted: from FY2020 they include CARES, CRRSA and ARPA relief, and from FY2021 the infrastructure law's AIG, terminal (ATRM) and contract tower (FCT) grants, so a total here is not AIP alone; the AIP share is shown separately. Tower operations are the FAA's ATADS counts for towered fields, calendar years 2010 to 2024; a field without a tower has no counts, and a year's dollars per operation divide a fiscal year's awards by the same-numbered calendar year's count. Grants to state block programs, system plans and proposed airports carry no airport identifier and are not shown on airport pages. Ranks count airports with at least one award in these years. Figures are as published and may be revised by the FAA; this is not FAA analysis.

Distances are great-circle from the airport reference point; bearings and winds are true. Conditions are each field's own METAR from the last two hours; a dash means it has none.
