Pilot’s question: Plan KHPN → KFRG tomorrow

Tools consulted: Looking up the airport, Analyzing the leg and its airspace, Fetching METAR/TAF, Reading NOTAMs, Checking sunset.

🛩️ VFR BRIEFING — KHPN → KFRG

24.3 NM direct · sunset 22:32 UTC

White Plains Class D → under the 3,000 ft Class B shelf → Farmingdale Class D. Both fields VFR, but NOTAMs close both Republic runways all day tomorrow:

09/051 B) 2609241707 C) 2610302200 E) RWY 01/19 CLSD EXC XNG 09/076 B) 2609291514 C) 2610050359 E) RWY 14/32 CLSD EXC XNG

Direct leg from Westchester County to Republic drawn under the New York Class B shelf.

🔴 No open runway at Republic tomorrow

Not an official briefing — always check the official publications. The pilot in command is the final authority.

The app

From “I want to fly tomorrow” to a ready nav log.

Route

Honest direct legs, swept against the airspace.

It plans a direct leg between your airports and checks every Class B, C and D along it against your planned altitude, plus the special-use airspace and the TFRs active at that moment, with frequencies from the FAA registry.

Nav log

A nav log, not a paragraph.

A leg table with heading, altitude and frequency. A contact timeline without gaps. Fuel against endurance. Latest takeoff computed from sunset at the destination — ready to clip to your kneeboard.

Weather

Every summary comes with the raw message next to it.

METAR and TAF appear exactly as NOAA published them, next to the decoded reading. You verify in seconds instead of trusting. SIGMETs, G-AIRMETs and PIREPs join the same read.

Weather

The message, as NOAA published it:

Overcast at 6,500 ft with 10 miles now — comfortably VFR. The TAF drops the deck to overcast 1,500 ft after 15Z tomorrow with a 30% chance of light rain: go early.

The airspace

Every direct leg, swept against the airspace you will fly through.

Class B, C and D, special-use areas and the TFRs active at that moment — with the floors and ceilings quoted from the official FAA data, not from memory.

The result is a briefing you can fly. “Remain below the 3,000-foot Class B shelf, Republic Tower on 118.8” is how the flight actually goes.

Trust

Every summary ships with its source attached.

The original message, always

Every METAR and every TAF appears exactly as published, next to the plain-language reading. The summary never replaces the original.

FAA and NOAA sources

FAA and NOAA — public-domain US government data. Live weather, NOTAMs and TFRs; forecast winds come from weather-model data.

Where the numbers come from

Numbers come from FAA and NOAA data, weather-model winds and code, not from the AI, and the source is shown so you can check.

Mandatory notice

AeroZulu is not an official source of preflight briefings and is not certified by any aviation authority, including the FAA. It is a planning aid. Always check the official FAA and NOAA sources before flying. The pilot in command retains full legal responsibility for the preparation and conduct of the flight.

FAQ

What pilots ask before subscribing.

Is AeroZulu an official source of preflight briefings?

No. It is an advisory planning tool. It reads the official publications and organizes them into a nav log, which can help you become familiar with the available information before a flight, the way 14 CFR 91.103 requires and AC 91-92 describes for third-party tools — but it is not certified by any aviation authority, and it does not replace the official sources. The pilot in command remains the final authority.

Where does the US data come from?

From official, public US government sources: airport data from the FAA NASR (about 4,900 public-use airports), terminal procedures and airport diagrams from the FAA d-TPP (24,000+ charts), aviation weather — METAR, TAF, SIGMET, G-AIRMET, PIREPs — from NOAA, and live TFRs from tfr.faa.gov. Forecast winds come from weather-model data.

How does it plan the route?

As a direct leg between your airports. Every Class B, C and D along it is checked against your planned altitude, along with the special-use airspace and the TFRs active at that moment.

Can it invent a frequency or an altitude?

It is built not to. Frequencies, altitudes, distances and fuel figures come from FAA and NOAA data, weather-model winds and code, not from the AI, and the source is shown so you can check. The AI writes the summary around those numbers and can still get one wrong, so check each one against the current chart before you fly.

Does it file flight plans?

No. It drafts the plan for you to review, but filing stays with the official channels and the services you already use.

How is it priced and billed?

Plans are billed in US dollars through the App Store or Google Play. Cancel anytime through the store.

Does it work offline?

No. Weather, NOTAMs and TFRs are fetched when you ask, because they change constantly — a briefing saved from yesterday would be worse than none. The exported route file, though, stays on your phone.

Your next briefing takes a minute.

Ask, check the sources, export the FPL or GPX — with official FAA and NOAA data.
