2°            departure aerodrome and estimated off-block time;

3°            destination aerodrome or operating site and total estimated flight time;

4°            mandatory reporting point for CTR exit;

5°            fuel endurance;

6°            total number of persons on board;

7°            name of the pilot in command.

(3) An abbreviated flight plan transmitted in the air by radiotelephony for the crossing of controlled airspace contains, as a minimum:

(1) VFR flights at night shall be operated exclusively in controlled airspace.

(2) A complete flight plan shall be filed for all VFR flights at night.

(3) Except when necessary for take-off or landing, or except when specifically authorised by the Direction de l’aviation civile, VFR flights at night shall be operated at a level which is at least 300 m (1 000 ft) above the highest obstacle located within 8 km of the estimated position of the aircraft.

(4)  Visibility and distance from cloud minima in visual meteorological conditions at night are the following:  

 

Altitude band 

Airspace Class    

Flight Visibility     

Distance from cloud

At and above 3 050 m (10 000 ft) AMSL

C and D

8 km

1 500 m horizontally

300 m or 1 000 ft vertically

Below 3 050 m (10 000 ft) AMSL and above 900 m (3 000 ft) AMSL, or above 300 m (1 000 ft) above terrain,  

whichever is the higher

C and D

5 km

1 500 m horizontally

300 m or 1 000 ft vertically

At and below 900 m (3 000 ft) AMSL, or 300 m (1 000 ft) above terrain, whichever is the higher

C and D

5 km

1 500 m horizontally

300 m or 1 000 ft vertically

However:

      1°            the ceiling shall not be less than 450 m (1 500 ft);

      2°            in airspace classes C and D, at and below 900 m (3 000 ft) AMSL or 300 m (1 000 ft) above terrain, whichever is the higher, the pilot shall maintain continuous sight of the surface
