ATPL Navigation study plan

Draw the full VOR receiver geometry (radial, bearing, CDI deflection, TO/FROM, cone of confusion) from memory and label every term

Solve 10 VOR/CDI interpretation problems, including station passage and off-course intercepts, without notes

Explain how a conventional VOR, Doppler VOR, and DVOR/DME co-located pair differ in signal generation and accuracy

List the standard service volumes and accuracy figures for VOR, DME, and NDB, and state the tolerances in degrees or NM

Trace the ADF/NDB signal path and explain night effect, coastal refraction, static interference, and quadrantal error

Convert between relative bearing, magnetic bearing, and QDM/QDR for 12 ADF scenarios

Describe ILS localizer, glideslope, and marker geometry, and calculate decision height versus glideslope intercept from given parameters

Summarize primary/secondary radar, transponder modes, and basic GNSS segment architecture and error sources

Construct the triangle of velocities for 15 wind-triangle problems and solve for heading, ground speed, track, and drift

Derive the wind velocity from two observed headings and ground speeds (double-drift method)

Compute revised ETA and required heading change after an in-flight wind update

State and apply the 1-in-60 rule to track-error and off-track corrections

Explain RNAV equipment types and the PBN navigation specifications (RNAV 5/2/1, RNP 1/0.3, RNP AR APCH) and their sensor and monitoring requirements

Describe waypoint types, fly-by versus fly-over, and path terminators (IF, TF, CF, DF, RF) in an RNAV procedure

Walk through FMS operation: flight-plan entry, performance initialization, lateral/vertical navigation modes, and database currency checks

Identify navigation-database AIRAC cycle rules and the consequences of an expired or mismatched database

Define the Earth models (sphere, ellipsoid, geoid) and convert between latitude/longitude, MGRS-style grid references, and bearing/distance on the sphere

Calculate great-circle distance and initial/final bearing for three given city pairs using the spherical formulas

Explain terrestrial magnetism: dip, variation, isogonals, and the agonic line, and apply variation to convert between true and magnetic

Describe deviation, compass swinging, and the operation of direct-reading and remote-reading (flux-gate/slaved gyro) compasses, including turning and acceleration errors

Compare Mercator, Lambert conformal conic, and polar stereographic projections on shape, scale, and great-circle representation

Identify chart symbols, airspace depictions, and scale/unit conversions on a typical 1:500 000 aeronautical chart

Plan and fly (simulated or on paper) a visual navigation leg using map reading, timing, and heading corrections

Execute position-fixing by visual landmarks, then apply a lost-procedure sequence (climb, conserve, communicate, navigate)

Distinguish great-circle and rhumb-line tracks and compute the difference in distance and initial bearing for a long oceanic leg

Explain grid navigation, grid heading, and the use of polar stereographic charts near the poles

Describe oceanic navigation requirements: MNPS/NAT HLA, RNP 4/10, contingency procedures, and strategic lateral offsets

Compare navigation sensors used in remote regions (INS/IRS, GNSS, and their failure modes)

Re-test every weak area flagged in weeks 1-7 using a personal error log

Complete two full-length timed mock exams under exam conditions

Review all missed items and write a corrected explanation for each

Consolidate a one-page formula and tolerance sheet covering all eight domains
