VFR - Visual Flight Rules

For a VFR flight in real life, you do not have to file a flightplan. In our virtual world however, a flightplan should always be filed.

VFR stands for Visual Flight Rules. The pilot must fly and navigate with visual reference to the surface. Due to this, there are certain weather criteria that must be met for a VFR flight to take place.

VFR flights are not permitted in Class A airspace, so there are no criteria.

There are no Class B or C airspace within the Havanna FIR, so we will not explain the criteria.

VFR Flight in Class D and Class E airspace:

At or above FL100:

  • 1,500 metres horizontally away from cloud
  • 1,000ft vertically away from cloud
  • In flight visibility of at least 8km

Below FL100:

  • 1,500 metres horizontally away from cloud
  • 1,000ft vertically away from cloud
  • In flight visibility of at least 5km

An aircraft is deemed to have complied with the below FL100 restrictions if the aircraft is not a helicopter and:

  • it flies at or below 3,000ft AMSL
  • it flies at a speed which is 140KIAS or less
  • remains clear of cloud, with the surface in sight and an in flight visibility of at least 5km

If it is a helicopter, it is deemed to have complied with the below FL100 restrictions if:

  • it flies at or below 3,000ft AMSL
  • it remains clear of cloud, with the surface in sight and an in flight visibility of at least 1,500 metre

IFR - Instrumental Flight Rules

  • In real life you should file a flight plan before starting an IFR flight
  • There is no altitude limit to fly IFR
  • IFR means that you fly and navigate to your destination by means of Navigational aids such as VOR beacons, NDB Beacons and Intersections.
  • If your flight commences outside controlled airspace (see airway charts) you do not need clearance to operate, however you must request an information service from an ATC unit and remain outside controlled airspace until cleared to enter.
