PERFORMANCE
5-10
Take off distance
Take-off distance, following recommended take-off profile described page
5-3 with 50 feet obstacle, at corresponding HIGE maximum gross weight is
330 m (1080 feet).
Glide distance in autorotation
In stabilized autorotation with collective fully down, rotor speed stays within
power-off rotor speed range. The following performance is then :
Minimum rate of descent ............................ 1770 feet / min at IAS = 49 kt IAS
- 0.8 kt IAS per 1000 feet Zp
Best angle of glide .......................... 0,60 nm per 1000 feet at IAS = 78 kt IAS
- 1.3 kt IAS per 1000 feet Zp
Sound exposure level
Cabri G2 flyover sound exposure level is :
75.7 dB SEL
Confidence interval ± 0.3 dB. This measurement was established taking into
account Vh = 100 kt IAS.
The sound exposure level was determined under ICAO regulation,
Annex 16, volume 1, 2
nd
part, chapter 11.
