Cross Winds Monitors (Aviation, Premium Layer)

The Cross Winds Monitors feature enables calculation and monitoring of wind components—headwind, tailwind, and crosswind—relative to a defined direction of travel. It is designed for aviation and other operational contexts where wind direction and alignment critically impact safety and performance.

Overview

• Parameters: Crosswind (speed and gust), Headwind, Tailwind

• Forecast Range: Real-time and forecast

• Supported Views: Map View, Dashboard, Insights, and Alerts

• Supported Location Types: Insights are supported for point, polygon, polyline, and cluster locations.

Note for Aviation Users: For runway-level accuracy, we recommend using a polyline location aligned with the runway heading. This enables more precise crosswind, headwind, and tailwind monitoring along the operational direction.

Location Direction Setup

Wind component monitoring requires a defined Direction for each location, representing the operational heading in degrees clockwise from true north.

How to Set Direction:

If you're monitoring a runway, first create a polyline location that aligns with the runway's heading.

Then:

1. Go to the Locations page

2. Select your polyline (or other location type)

3. Edit the Direction field (0–359°, measured clockwise from true north)

4. Save changes

Insights and Alerts

Creating an Insight

• Navigate to the Insights tab

• Select the wind component(s):

  • Crosswind

  • Headwind

  • Tailwind

• Define thresholds (e.g., Crosswind Gust > 25 kt)

• Choose any supported location type with a direction set

Configuring Alerts

• Use the Insight to trigger alerts

• Options include start, end, all-clear, and prior notice

• Delivery methods: Email, SMS, and app push notifications

Notes

• Direction must be set per location to activate component calculations

• This feature is most useful for aviation takeoff/landing monitoring, railway and road safety, and UAV operations
