Mauritius DCA IR Theory study plan

Explain how VOR, DME, NDB/ADF and ILS ground and airborne components work together to give bearing, range and deviation information

Convert between true, magnetic and relative bearings and compute QDM, QDR, QUJ and QTE for a given station and aircraft heading

Read an instrument approach chart and label the final approach course, glidepath angle, threshold crossing height, minima and missed approach point

Derive still-air time, fuel and distance for a 250 NM IFR leg given TAS, wind and fuel flow

Describe RNAV/GNSS area navigation: waypoint types, fly-by versus fly-over, RAIM, and approach minima categories (LNAV, LNAV/VNAV, LPV)

Interpret a PBN navigation specification at the level of RNP accuracy value, containment and onboard performance monitoring

Compute wind triangle solutions to find heading and groundspeed from course, TAS and wind

Calculate top-of-descent point and required rate of descent for a 3-degree path at given groundspeed

Interpret METAR, TAF, TREND and SPECI reports including CAVOK, RVR groups and colour codes

Decode significant weather charts and low-level prognostic charts to extract freezing level, jet stream and turbulence areas

Explain how pressure systems, fronts and orographic effects around Mauritius produce low cloud, heavy showers and trade-wind turbulence

Convert between QNH, QFE and QNE and state the altimeter error when flying from high to low pressure

Describe icing types, conditions favouring airframe icing and the hazards of freezing rain and supercooled large droplets

Explain thunderstorm lifecycle, microburst and wind shear recognition cues and the recovery actions for each

State the IFR cruising level semicircular rule, the transition altitude/level concept and minimum IFR flight levels

Summarise position reporting, SSR transponder and communication failure procedures under IFR

Sequence a standard instrument departure: read SID text and chart, set climb gradient, and compute required rate of climb for a given groundspeed

Describe the segments of an instrument approach and the criteria for starting a missed approach

Explain pitot-static and gyroscopic instrument failure modes and the resulting indications on the attitude, heading and airspeed indicators

Identify the electrical, vacuum/pressure and alerting systems whose failure degrades IFR capability, and state the alternate means available

Apply approach category speeds, DA/MDA, visibility and RVR requirements to decide go/no-go at minima

Explain holding pattern entry selection, timing and wind correction for a published hold

State the rules on alternate aerodrome selection, fuel planning and dispatch minima for an IFR flight

Describe the actions and phraseology for a radio communication failure in IMC and for an emergency descent

Explain sensory illusions in IMC (somatogravic, somatogyral, leans) and the instrument cross-check that counters each

Describe spatial disorientation, hypoxia, hyperventilation and fatigue: recognition, effect on instrument scan and countermeasures

Explain stability, load factor, stall speed change with bank and the effect of icing and turbulence on instrument-flight margins

Interpret the lift, thrust and drag relationships behind climb performance and the drift-down profile after engine failure

Complete two timed full-length mock exams under exam conditions and record the score per domain

Re-teach the three weakest domains from the mock results using only self-written notes

Rehearse chart-reading speed: decode a METAR, an approach chart and a SID within a fixed time limit each

Consolidate a final one-page list of formulas, minima rules and memory aids for last-minute review
