The IRPA logo, approved by the 12th Executive Council at Aviemore (June 1974) as the official symbol of IRPA, was designed by the Czechoslovak artist Pavel Sváb (born 1936).

It was designed with the idea to convert the negative, suppressive meaning of the warning trifoil into a positive one symbolizing protection, health, prosperity. By repeating the extension of one edge of the segment into a smooth curve in the series of all three segments a new configuration with three arms arises negating by its form and position the repelling meaning of the warning trifoil.
