Destination and Alternate Aerodrome Requirements

4.9.2 VFR Night and IFR

All night VFR and IFR flights shall be conducted along airways or air routes. Company IFR or night VFR routes may be established for use in uncontrolled airspace using the following criteria:

1. 
   A minimum obstruction clearance altitude (MOCA) shall be established for each route segment by the use of aeronautical charts and the State AIP for updating of significant obstructions as follows:
   
   1. 
      for flight under IFR a minimum altitude of 2,000 ft above the highest obstacle located within a horizontal distance of 10 miles from the centerline of route;
      
   2. 
      for flight at night in VFR conditions a minimum altitude of 1,000 ft above the highest obstacle located within 3 miles from the centerline of the route.
      
2. 
   For each route segment a minimum en-route altitude (MEA) shall be established which meets or exceeds the minimum obstruction clearance altitude and assure navigational signal coverage. For line of sight navigation aid reception distance, for ground installed aids the minimum reception altitude may be calculated by calculating the square root of an altitude above the navigation aid and multiplying the result by 1.25 (Sq. root 3,000 ft. is 54.7 x 1.25 = 68 miles). The MEA will be established to the nearest higher 100 ft increment.
   
3. 
   Each route shall include:
   
   1. 
      the FROM/TO route segment;
      
   2. 
      track;
      
   3. 
      MOCA;
      
   4. 
      MEA;
      
   5. 
      distance between fixes or waypoints; and
      
   6. 
      navigation aids.
      
4. 
   To assist pilots in flight planning on such routes, (Company Name) maintains a catalogue of established routes in the Flight Department Office.
   
5. 
   The flight visibility shall not be less than 3 miles for flights in VFR at night.
   

4.9.3 IFR

The weather minima used for IFR departures and approaches shall be those specified in the standard instrument approach procedures used by (Company Name). Where there is no published instrument approach or departure procedure the take-off minima will be ½ mile visibility. Operations at reduced take-off minima must be conducted in accordance with section 4.10.1 and Category II operations conducted must be conducted in accordance with section 4.11.
