Abstract
ICAO CAEP is encouraged to adopt - as an alternative - the noise certification procedure for ultralight aeroplanes as introduced in the Federal Republic of Germany. This procedure follows the ANNEX 16 Chapter 6 procedure with the following changes, thus making the noise certification procedure very simple and inexpensive to conduct, while maintaining a sufficient degree of accuracy: - No definition of atmosperic reference conditions - No restrictions with respect to ambient relative humidity - Narrower air temperature window (8 degrees centigrade to 10 degreescentigrade) - Test flight height between 75 m to 150 m - Equal numbers of flights for head and tail wind conditions - Engine to be operated at full throttle maximum take-off power - Application of a ground board microphone system - No noise data adjustment for atmospheric attenuation, helical blade tip Mach number (air temperature) and no performance correction.
