How this service works
Density altitude at an airport from live temperature and pressure: performance penalty for aircraft and drones.
Output
Returns the computed density altitude in feet, pressure altitude in feet, current temperature and ISA standard temperature, altimeter setting, field elevation, a human-readable summary, a performance verdict (e.g. normal/high/very high), degraded-data flags, data source URL and age in minutes, and configurable thresholds for high and very-high density altitude warnings.
Example use cases
High-altitude airport departure check
“I'm flying out of Aspen (KASE) this afternoon — what's the density altitude right now and is it dangerously high for a light aircraft departure?”
Hot-day drone flight planning
“Before I launch my drone at KBUR today, can you check the density altitude and tell me if the heat is going to hurt its hover performance?”
Summer mountain flight safety briefing
“We're planning a flight out of KGTU this morning — pull the density altitude and let me know the performance verdict so we can decide if we need to reduce our load.”

Endpoint
GEThttps://aviation-weather.x402tookit.com/density-altitude?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a computed density altitude value (not just raw METAR data) along with a plain-language performance verdict, especially for high-elevation or high-temperature airports where density altitude is a safety-critical concern. It is preferable over raw weather endpoints when you need the ISA deviation, pressure altitude, and a ready-made assessment of whether conditions are safe for aircraft or drone operations — without performing the calculation yourself.
Side effects
- Invalid or unknown ICAO code returns an error or null fields
- Live weather data unavailable for remote airports may result in degraded=true with partial results
- Stale METAR data indicated by high ageMinutes value
- Missing altimeter or temperature readings prevent accurate density altitude calculation
- Network timeout or payment failure returns no data
