- rounded average PRR
- Typical values for average conditions and average ambient brightness; in bright sunlight the operational range may be considerably shorter and the operational flight altitude may be considerably lower than under an overcast sky.
- The maximum range is specified for flat targets with size in excess of the laser beam diameter, perpendicular angle of incidence, and for atmospheric visibility of 40 km. Range ambiguities have to be resolved by multiple-time-around processing.
- Typical values for 60 % reflectance, max. effective FOV 58°, additional roll angle ± 5°
- Nominal Ocular Hazard Distance, based upon MPE according to IEC 60825-1:2014, for single line condition
- Extended Nominal Ocular Hazard Distance, based upon MPE according to IEC 60825-1:2014, for single line condition
- NOHD and ENOHD have been calculated for a typical angular step width of 0.012°, an aircraft speed higher than 10kn, and beam divergences of 0.72 mrad for the green laser and 0.25 mrad for the IR laser. NOHD and ENOHD increase when reducing the angular step width or the green laser’s beam divergence.

- Extended Nominal Ocular Hazard Distance, based upon MPE according to IEC 60825-1:2014, for single line condition
- NOHD and ENOHD have been calculated for a typical angular step width of 0.012° which means non-overlapping laser footprints and an aircraft speed higher than 10kn. NOHD and ENOHD increase when using overlapping laser footprints which may be intended e.g. for power line mapping.
