The input fields required for computations are presented in a user friendly and logical display.
After completing the associated conditions, select Calculate to see your holdover time.
All associated holdover chart notes are incorporated and prompts for additional required input are presented to the user when necessary.

Holdover Calculator incorporates an Auto-Populate feature which retrieves and detects pertinent weather conditions from the METAR for the ICAO airport identifier provided by the user.
This makes the process of determining a holdover time even quicker!
