Mhepo yakasimba, chirongwa chisingagumi nguva dzose kumhepo yepamusoro, inopa ruzivo rwakakosha kune vanofambisa ndege. Zvakakosha kuti ndege iende mumhepo uye irege kudzika nemhepo. Mukuwedzera, dzose ndege dzinenge dzakagadziriswa zvakagadziriswa mumhepo-inomhanya yemhepo iyo ndege inopinda kune ngozi pane imwe nzvimbo yepandeti. Sezvo zvakadaro, zvakakosha kuti vatyairi vangave nekukurumidza uye nyore nzira yekuona mhepo yekufambisa uye kutungamira vasati vasvika-kufanana ne windsock.
Mhepo dzakawanda dzinokonzerwa nemhepo dzinoitwa kuti dzizvienzane nemhepo kana mhepo inokurumidza kupfuura mazano matatu. Pakufambisa kwemhepo ine mapfundo gumi nemashanu uye zvakakura, iyo windsock ichazara zvakakwana uye inoratidza nzira yakasiyana iyo mhepo inovhuvhuta. (Kana mhepo inoputika ye windsock inotarisa kuchamhembe, mhepo iri kuuya ichibva kumaodzanyemba.) Nezivo iyi, unogona kufunga kuti kana windsock iri hafu-yakareba, mhepo inenge inenge inosvika mazana manomwe.
Kune dzimwe nzvimbo dzisingadzorwi uye ndege dzomumhepo, windsock ndiyo chete inoratidza kuti mhepo iri kuitei. Zvizhinji zvezvikwata zvepamusoro zvekare zvinoshandisawo maziso ekucherechedza maitiro (AWOS) kana kuti inonzi automatic information information system (ATIS), iyo inogona kupa mhepo yekufambisa uye inotungamirira data kubva kune anemometer kana sensor iri mumunda. Kuziva nzvimbo ye anemometer kana mamwe masheji ari mumunda, pamwe chete nemhepo inonzi windsock, ichakubatsira kuziva kuti mhepo inotungamirirwa nekukurumidza pane nzvimbo dzakasiyana mumunda.
