Designed by an Airline Pilot and Gold Seal FAA Flight Instructor, Runway Wind Calculator rapidly and accurately computes runway wind components for takeoff and landings.

The simple user interface and intuitive graphical display makes for an ideal tool to be used during preflight or in-flight by pilots of all experience levels.

During computation the Runway Wind Calculator establishes if the current parameters are within your personal or aircraft specific limitations.

The app allows input of your personal caution and warning levels as well as aircraft limitation. The exceedance of any parameters is intuitively displayed, as the affected wind component will turn orange (caution) or red (warning) for personal or aircraft limitation, immediately alerting the pilot of the potential hazard.

This application can be used by CFIs as well to help teach students about wind components.

The use of personalized limits can help assist the students in good decision making and bring some comfort to CFIs sending students on solo flights.

Runway, wind data and limitations are saved upon exit making it effortless to quickly update and get a new read on the current weather condition.

Good and could be better

Very simple and easy to use x-wind calculator than can easily be used in flight. Only improvement I would recommend would be to have the results display in as large of text as the inputs. Makes it easier to read when being bounced by turbulence and gusting winds.

Easy to use on the fly

I really liked that you can set aircraft and personal limits. The interface is easy to read and easy to use during flights. Rapidly became one of my flying essentials.
