flight-time

根据高空风速估算机场间的飞行时间。当您需要计算飞行时长、规划行程，或对比不同航线时，可使用此技能。只需输入出发/到达的 ICAO 机场代码、巡航高度，以及真实空速即可。

name: flight-time
description: Estimate flight time between airports accounting for winds aloft. Use when calculating flight duration, planning trips, or comparing routes. Takes departure/arrival ICAO codes, cruise altitude, and true airspeed.

Flight Time Estimator

Calculates estimated flight time between two airports using:

  • •Great circle distance
  • •Current winds aloft forecast (from NOAA Aviation Weather)
  • •True airspeed at cruise altitude

Usage

bash
~/clawd/skills/flight-time/scripts/flight_time.py KDEP KARR --altitude FEET --tas KNOTS

Examples

bash
# Huntsville to Atlanta at 6000ft, 140kt TAS
flight_time.py KHSV KFTY --altitude 6000 --tas 140

# Dallas to Denver at 10000ft, 165kt TAS
flight_time.py KDAL KDEN --altitude 10000 --tas 165

# JSON output for scripting
flight_time.py KHSV KFTY --altitude 6000 --tas 140 --json

Parameters

  • •departure: ICAO code (e.g., KHSV)
  • •arrival: ICAO code (e.g., KFTY)
  • •--altitude: Cruise altitude in feet MSL
  • •--tas: True airspeed in knots
  • •--json: Output as JSON (optional)

Output

Returns:

  • •Distance (nm)
  • •True course
  • •Winds at altitude (from nearest FB station)
  • •Ground speed
  • •Estimated flight time
  • •Wind effect (headwind/tailwind impact in minutes)

Data Sources

  • •Airport coordinates: NOAA Aviation Weather API
  • •Winds aloft: NOAA FB winds forecast (6-hour)

Limitations

  • •Uses single wind observation at route midpoint (not full route interpolation)
  • •Does not account for climb/descent phases
  • •Wind data updates every 6 hours
  • •No terrain or airspace considerations
