NCAA Namibia Night Rating Theory study guide
NCAA Namibia Night Rating Theory · Work through your exam, one topic at a time.
The NCAA Namibia Night Rating is the licence endorsement that allows a pilot to act as pilot-in-command of an aeroplane at night, and the theory examination is the knowledge gate that sits alongside the required dual night flying instruction. It is written for holders of a valid Namibian private or commercial pilot licence (aeroplane) who have completed the night flying syllabus with an approved flight training organisation and now need to demonstrate the ground knowledge behind it. The NCAA Namibia Night Rating Theory study guide has 10 sections and about 3,069 words.
01Night Vision and Visual Illusions
At night the retina switches from cone to rod vision. Cones give colour and fine detail but need moderate light; rods are colourless, much more sensitive, and concentrated outside the fovea.
378 words, about 2 min02Night Aeromedical Factors and Fatigue
The body clock drives a circadian low, typically 02:00–06:00, when core temperature, alertness and reaction time are at their worst. A night-rated pilot must plan around this, not fight it.
340 words, about 2 min03Aircraft Lighting Systems and Cockpit Lighting
Navigation lights are red on the left (port), green on the right (starboard) and white at the tail. They must be on from sunset to sunrise, and whenever the aircraft is moving on an apron.
305 words, about 2 min04Night Navigation
Night navigation uses the same dead reckoning as day, but with fewer outside cues. Before flight, calculate heading, groundspeed, ETA and fuel for each leg, and note minimum safe altitude, terrain, obstacles, airspace and the lighting hours or PPR of destination and alternate.
290 words, about 1 min05Charts and Position Fixing
The 1:500,000 chart is the normal planning chart. Know the symbols for controlled airspace, prohibited and restricted areas, spot heights, obstacles, radio navigation aids and airfield data.
309 words, about 2 min06Night Meteorology and Aerodrome Forecasts
A METAR is an observation; a TAF is a forecast with a validity period. Learn the change groups: FM indicates a rapid change, BECMG a gradual change, TEMPO a temporary fluctuation, and PROB30/PROB40 a 30% or 40% probability.
287 words, about 1 min07Night Operations
Night operations begin before sunset. Check personal fitness, night currency and recent experience; carry a torch and spare batteries; confirm airfield lighting hours, PPR and the alternate's weather.
316 words, about 2 min08Airfield Lighting and ATC Procedures
Runway edge lights are white, with the last 600 m or half of the runway (whichever is less) coloured amber/yellow to warn of the end. Threshold lights are green, runway end lights red, and centreline lights white.
304 words, about 2 min09Human Performance and Decision Making at Night
Night flying reduces the cues available for building a mental model. Monitor position, fuel, weather, terrain and system status actively.
239 words, about 1 min10Emergency Procedures and Abnormal Situations at Night
At night there is little chance of selecting a field visually. Maintain control, establish best glide, turn toward the nearest suitable area or airfield, squawk 7700 and transmit MAYDAY with position and intentions.
