Brunei DCA CPL(A) Radio Navigation study plan

Explain how frequency, wavelength and the speed of light relate, and calculate wavelength or frequency for the VHF, UHF and LF/MF bands used in navigation aids

Distinguish ground wave, sky wave, space wave and ducting, and predict which propagation mode dominates for NDB, VOR and DME signals

Describe how ionospheric and tropospheric refraction, absorption and fading affect usable range and signal quality at VHF and below

State the operating principle of VOR: frequency band, phase comparison between reference and variable signals, and how radial information is derived

Convert between VOR radials, magnetic bearings and aircraft headings, and sketch a station passage with the CDI centred

Distinguish conventional VOR, Doppler VOR and DVORTAC in terms of accuracy, siting constraints and multipath immunity

Explain DME operation: pulse pairs, interrogation and reply timing, slant-range error and the relationship between DME distance and true range

Interpret TACAN bearing and distance output and state how a TACAN differs from a VOR/DME pair and what an aircraft with only VOR/DME can use

Calculate line-of-sight range from aircraft and station heights and identify when a DME or VOR will drop out

Describe how VOR/DME fixes are plotted and how a single VOR/DME pair yields both bearing and range for a position fix

Explain NDB/ADF principles: frequency band, antenna types, sensing and non-sensing, and how the ADF needle indicates relative bearing

Convert among relative bearing, magnetic bearing and true bearing, and compute QDM, QDR and intercept headings from an ADF indication

Describe the ILS localiser and glidepath signals, their frequencies, modulation and the meaning of a CAT I decision height and course/glidepath widths

Interpret the ILS deviation indications and marker beacons or DME distance, and state the flyable tolerances and failure indications

List the limitations of NDB/ADF including night effect, coastal refraction, static and thunderstorm interference, and describe ILS critical-area and false-glidepath hazards

Explain area navigation concepts: waypoint types, track-to-waypoint, cross-track error and how RNAV equipment builds a flight plan

Describe GNSS architecture, the position solution from pseudoranges, and the roles of GPS, GLONASS, Galileo and BeiDou in multi-constellation receivers

Define RNP and RNAV, describe PBN navigation specifications (RNAV 5, RNAV 1, RNP 1, RNP APCH) and the meaning of on-board performance monitoring and alerting

Distinguish LNAV, LNAV/VNAV, LP and LPV minima and state which augmentation each requires

Interpret a GNSS receiver display: number of satellites, HDOP or accuracy figure, RAIM status and integrity warnings

Describe primary radar principles: pulse transmission, echo timing, range resolution and the factors that limit detection

Explain secondary surveillance radar: interrogation modes A, C and S, transponder replies, and how Mode C and Mode S altitude data are derived

Distinguish ground-based augmentation (GBAS) from satellite-based augmentation (SBAS) in terms of reference stations, corrections, integrity and coverage

Describe how SBAS delivers vertical guidance for LPV approaches and what a GBAS precision approach service provides

Interpret airborne weather radar returns: reflectivity, gain control, tilt management and the hazards of attenuation and bright band

Read and interpret a typical radio navigation instrument panel, identifying CDI, HSI, RMI, DME, ADF and GNSS annunciations and their failure flags

Plan and describe a practical en-route navigation sequence using VOR, DME and GNSS cross-checks, including position monitoring and gross-error checks

Explain RAIM prediction, fault detection and exclusion, and the conditions under which GNSS integrity is unavailable

Identify and describe the causes of common errors: multipath, interference and jamming, ionospheric scintillation, terrain masking and station siting errors

State the operational limitations and NOTAM-type considerations for each aid, and describe how to detect and manage an erroneous navigation indication

Consolidate all nine domains by producing a condensed revision summary of the key facts for each domain

Practise calculation-heavy items: wavelength, LOS range, slant range, bearing conversion, cross-track error and time-to-station

Review weak areas identified in earlier weeks and re-solve the questions previously missed

Describe and distinguish each navigation aid's frequency band, principle, accuracy and limitations from memory

Re-test the weakest domains from week 7 and achieve a clear improvement on the second attempt

Practise full-length timed mock papers under exam conditions and review every incorrect answer

Explain PBN, GNSS augmentation, integrity and interference topics aloud or in writing without notes

Confirm readiness by listing the remaining knowledge gaps and closing them with targeted review
