ofthescreen.Bylooseningthetwohoseclampsetscrews,thecamerabodycanrotatetobettersquare

Thecarbumpersshouldalsoendupbeingparallelwith

OtherImportantFieldofViewConsiderations

1)MakesurethatthereisnohorizonintheFOV.ThiscanresultinseriousoperationalproblemsforEast
or Westapproaches.Why? Becauseofthesun!Duringsunrise or sunset the sun can completely blind
thecamera.ProperFOV,visoradjustment,andcameratiltcanpreventthispotential
problem.
