CAA NZ Instrument Rating Navigation case studies
CAA NZ Instrument Rating Navigation · Put your knowledge to work in context.
The CAA NZ Instrument Rating Navigation examination is the navigation paper that New Zealand instrument rating candidates sit as part of the theory requirements for an instrument rating. It is aimed at pilots who already hold a licence and are working toward flying under instrument flight rules, and who therefore need to plan, monitor and replan flights without reliable visual reference to the ground. The navigation syllabus centres on the practical use of the New Zealand aeronautical information environment: flight planning and fuel/endurance calculations, tracks, headings and drift, wind triangle work, time and distance estimation, radio-navigation aids and area navigation, and the interpretation of AIP New Zealand publications, charts and meteorological information. Preparation should be built around current Civil Aviation Rules and the current AIP, since chart formats and procedures change, and around repeated timed practice at the calculation types that appear in the paper rather than passive reading. The CAA NZ Instrument Rating Navigation case studies are 5 cases and about 2,112 words.
1VOR/DME groundspeed, fuel and inbound tracking
You are the pilot of a twin-engine IFR aircraft tracking outbound on R-090 from the KAI VOR at 8,000 ft. TAS is 150 kt and fuel flow is 40 L/h.
484 words, about 2 min2RNAV GNSS approach with cold temperature and baro-VNAV limit
With reference to the RNAV (GNSS) RWY 23 approach at fictional Tiko (elevation 1,200 ft), you are cleared to conduct the LNAV/VNAV approach. The published LNAV/VNAV minima are 1,560 ft AMSL; the LNAV MDA is 1,620 ft AMSL.
380 words, about 2 min3Night NDB approach with static and suspect bearing
You are flying a night NDB approach to a coastal aerodrome. The only approved aid is the WAI NDB, 4 NM inland from the coast.
403 words, about 2 min4In-flight DR revision and diversion fuel judgement
You are on an IFR flight from Alpha to Bravo, a planned 150 NM leg. TAS is 105 kt, the planned wind is 240/25, and the flight-plan groundspeed is 95 kt.
445 words, about 2 min5RNP integrity loss in remote airspace
You are in IMC at FL 190 on an RNP 2 route in remote controlled airspace. The GNSS receiver annunciates 'INTEGRITY' and shows ANP 2.4 NM; the route requires RNP 2.
