POSITION REPORTING - Standard.
VISUAL FLIGHT RULES
Standard except:
1.
Except when operating as a special VFR flight, VFR flights shall be conducted so that the aircraft is flown in conditions of visibility and distance from clouds equal or greater than those specified in Table 1.
2.
Except when a clearance is obtained from an air traffic control unit, VFR flights shall not take off or land at an airport within a control zone, or enter the airport traffic zone or traffic pattern:
a.
When the ceiling is less than 450 M (1500’); or
b.
When the ground visibility is less than 5 km.
3.
VFR flights between sunset and sunrise are not authorized within Port-au-Prince FIR.

Airspace Classifica -tion B CDE FG
Above 900 M (3000’) AMSL or Above 300 M (1000’) above terrain, whichever is higher. At and below 900 M (3000’) AMSL or 300 M (1000’) above terrain, whichever is higher.
Distance From cloud Clear of cloud 1500 M horizontally 300 M (1000’) vertically Clear of clouds and in sight of the surface
Flight visibility 8 km (4.3 NM) at or above 3050 M (10,000’) AMSL 5 km below 3050 M (10,000’) AMSL 5 km**
* When the height of the transition altitude is lower than 3050 M (10,000’) AMSL, FL100 should be used in lieu of 10,000’.
** When so prescribed by the appropriate ATS authority:
a. Lower flight visibilities to 1500 M may be permitted for flights operating:
(1)
At speeds that, in the prevailing visibility, will give adequate opportunity to observe other traffic or any obstacles in time to avoid collision; or
(2)
In circumstances in which the probability of encounters with other traffic would normally be low, e.g. in areas of low volume traffic and for aerial work at low levels.
b.
Helicopters may be permitted to operate in less than 1500 M flight visibility, if maneuvered at a speed that will give adequate opportunity to observe other traffic or any obstacles in time to avoid collision.
4. Unless authorized by the appropriate ATS authority, VFR flights shall not be operated:
a.
Above FL180
b.
At transonic and supersonic speeds.
5. Except when necessary for take-off or landing, or except by permission from the appropriate authority, a VFR flight shall not be flown:
