How to read a METAR for Airbus takeoff

🔵 1. Structure of a METAR

Example:

LFPG 231030Z 24010KT 9999 FEW020 SCT040 BKN080 12/07 Q1015

Breakdown:

LFPG → ICAO code (Paris CDG)
231030Z → Date/time: 23rd at 10:30 Zulu
24010KT → Wind: 240° at 10 knots
9999 → Visibility: 10 km or more
FEW020 SCT040 BKN080 → Clouds: few at 2000 ft, scattered at 4000 ft, broken at 8000 ft
12/07 → Temperature/dew point: 12°C / 7°C
Q1015 → QNH: 1015 hPa

🔵 2. Key Elements for Airbus Takeoff

✔ Wind (24010KT)

Used to determine runway in service and calculate crosswind/headwind.

✔ Visibility (9999)

Must meet minimums for takeoff (usually > 400m for CAT I).

✔ Clouds (FEW/SCT/BKN)

Important for ceiling and departure clearance.
Low clouds (<2000 ft) may affect SID or require alternate procedures.

✔ Temperature (12/07)

Used for performance calculations (flex temp, engine thrust).

✔ QNH (Q1015)

Set in the FCU before departure. Affects altitude readings and terrain clearance.

🔵 3. Runway Selection Based on Wind

Wind 240° → use runway closest to 240° heading (e.g., RWY 26)
Avoid tailwind. Use headwind or acceptable crosswind.

🔵 4. Cloud Base and Ceiling

Clouds like BKN020 mean broken layer at 2000 ft.
If ceiling is below minimums, takeoff may be delayed or require alternate procedures.

🔵 5. Using METAR in Airbus Systems

🔵 6. Quick Summary

Reading a METAR correctly ensures safe, compliant, and optimized Airbus takeoff procedures.
