Regarding a helicopter flight, which of the following statements are correct? 1) Before a VFR flight it’s advisable to brief passengers that in the event of bad weather, the flight may divert, return to base or carry out a precautionary landing. 2) It’s encouraged that all precautionary landings are reported to the CAA within 10 days via the MOR (Mandatory Occurance Reporting) scheme. 3) Flight into degraded visual environment can lead to a loss of situational awareness. 4) A VFR pilot should divert when visual conditions deteroriate and therefore there’s no need to plan for precautionary landings.
