Mauritius DCA IR Theory study guide
Mauritius DCA IR Theory · Work through your exam, one topic at a time.
The Mauritius Department of Civil Aviation (DCA) Instrument Rating theoretical knowledge examination is the written knowledge gate that a licence applicant must clear before the instrument flying phase and the IR skill test. It is aimed at pilots holding, or working towards, a CPL or ATPL who want the privilege to fly under IFR in IMC - in Mauritian airspace and, given the island's isolation over the Indian Ocean, on long over-water sectors where there is no convenient diversion. The Mauritius DCA IR Theory study guide has 8 sections and about 2,200 words.
01Air Law and ATC Procedures (IFR)
Air Law and ATC Procedures for IFR covers the legal framework and clearance discipline used in the Mauritius FIR. Expect questions on ICAO Annex 2 IFR rules, Doc 4444 separation and read-back, AIP Mauritius route and approach data, and DCA requirements for flight plans, altimetry and communication failure.
303 words, about 2 min02Instrument Flight: Aircraft General Knowledge (systems relevant to IFR flight)
Aircraft General Knowledge for IFR concentrates on systems that affect instrument flight: pitot-static, gyroscopic and ADC sources, electrical power, ice protection, pressurisation and oxygen, autopilot and flight director, and warning systems. Expect system-failure effects, not maintenance detail.
293 words, about 1 min03Instrument Flight: Flight Performance and Planning
Flight Performance and Planning tests mass and balance, take-off and landing data, climb gradient, fuel policy and alternate planning for an IFR flight. Mauritius conditions, with warm humid air, a sea-level airport and limited alternates, make density altitude and fuel reserve questions common.
291 words, about 1 min04Instrument Flight: Human Performance and Limitations
Human Performance and Limitations looks at how pilots perceive, decide and perform under IFR workload: hypoxia, spatial disorientation, fatigue, stress, vision, hearing, CRM and automation. Questions often ask for the first corrective action.
254 words, about 1 min05Instrument Flight: Meteorology
Meteorology for IFR covers METAR and TAF interpretation, altimetry, icing, thunderstorms, tropical systems and local effects in the Mauritius area. Expect questions that link a forecast to a go/no-go or alternate decision.
277 words, about 1 min06Instrument Flight: Navigation (radio navigation and area navigation)
Navigation covers radio navigation and area navigation: VOR and DME, ILS, NDB, GNSS, RNAV and RNP, PBN, waypoints and CDI or HSI interpretation. Expect tracking, interception and database questions.
265 words, about 1 min07Instrument Flight: Operational Procedures (departure, en route, approach, and missed approach)
Operational Procedures covers the IFR flight from departure to missed approach: take-off minima, SID, climb gradient, en-route monitoring, approach briefing, stabilised approach, DA or MDA, MAPt and alternate. Expect sequence and decision questions.
265 words, about 1 min08Instrument Flight: Principles of Flight (instrument flying)
Principles of Flight for instrument flying tests attitude instrument flying, stability, control, trim, load factor, turn coordination and unusual attitude recovery. It is about flying accurately without outside reference.
