d) nil when the peak value of the cube root of EDR is below or equal to 0.1. Note.— The EDR is an aircraft-independent measure of turbulence. However, the relationship between the EDR value and the perception of turbulence is a function of aircraft type, and the mass, altitude, configuration and airspeed of the aircraft. The EDR values given above describe the severity levels for a medium-sized transport aircraft under typical en-route conditions (i.e. altitude, airspeed and weight). 2.6.3 Special air-reports Special air-reports on turbulence shall be made during any phase of the flight whenever the peak value of the cube root of EDR exceeds 0.7. The special air-report on turbulence shall be made with reference to the 1-minute period immediately preceding the observation. Both the average and peak value of turbulence shall be observed. The average and peak values shall be reported in terms of the cube root of EDR. Special air-reports shall be issued every minute until such time as the peak values of the cube root of EDR fall below 0.7. 2.7 Humidity The humidity shall be reported as the relative humidity, rounded to the nearest whole per cent. Note.— The ranges and resolutions for the meteorological elements included in air-reports are shown in Table A4-3.
