1What Earth model is normally assumed for standard air-navigation formulae such as departure and convergency?

A.An oblate spheroid, slightly flattened at the poles

B.A perfect sphere of constant radius only

C.A prolate spheroid elongated toward the poles

D.A flat plane where great-circle and rhumb-line distances are identical

Explanation: Although the physical Earth is an oblate spheroid, standard air-navigation formulae such as departure and convergency treat the Earth as a perfect sphere of constant radius. Ellipsoidal models are used in precise geodesy and some inertial/GNSS systems, but the spherical assumptions underpin classical departure, convergency and conversion-angle calculations.

2A great circle is best described as:

A.The intersection of the Earth's surface with a plane through the Earth's centre; its shorter arc is the shortest path between two points

B.Any circle whose plane does not pass through the Earth's centre

C.A line that cuts all meridians at the same constant angle

D.Any parallel of latitude including the Equator only when labelled magnetic

Explanation: A great circle lies in a plane through the Earth's centre. The shorter great-circle arc is the shortest surface distance between two points, which is why long-range tracks approximate great circles.

3Which statement about a rhumb line is correct?

A.It is always shorter than the great-circle path between the same points

B.It coincides with a great circle at all latitudes on every parallel

C.It cuts every meridian at the same angle and plots as a straight line on a Mercator chart

D.It cannot be flown at a constant true heading in still air

Explanation: A rhumb line maintains constant true direction, cutting meridians at a fixed angle. Mercator charts portray rhumb lines as straight lines, which is convenient for constant-heading legs even though the path is usually longer than the great circle.

4Two points both at 60°N are 20° of longitude apart. What is the east–west departure between them?

A.600 NM

B.1 200 NM

C.1 040 NM

D.300 NM

Explanation: Departure = (Δlongitude in minutes) × cos(latitude). Δlong = 20 × 60 = 1 200 minutes; cos 60° = 0.5; departure = 600 NM. Away from the Equator you must always apply the cosine of latitude.

5An aircraft flies due north along a meridian from 10°S to 20°N. How far has it flown?

A.600 NM

B.1 200 NM

C.1 800 NM

D.900 NM

Explanation: Along a meridian, one minute of latitude equals one nautical mile. Latitude change is 30° = 1 800 minutes = 1 800 NM. No cosine correction applies on a meridian.

6For air navigation, one nautical mile is approximately:

A.1 000 metres

B.Exactly 5 280 feet

C.1 852 metres, historically one minute of arc along a meridian

D.One minute of longitude at every latitude

Explanation: The international nautical mile is 1 852 m and historically matches one minute of latitude along a meridian. Minutes of longitude equal one NM only at the Equator.

7UTC used in aviation flight plans and meteorological reports is referenced to:

A.Local mean time at the aircraft longitude

B.Apparent solar time at destination

C.Mean time at the Greenwich meridian (0° longitude)

D.Pakistan Standard Time without conversion

Explanation: UTC is the global aviation time standard tied to the Greenwich meridian. Using UTC for flight plans, METARs and ETAs keeps crews and ATC on one clock worldwide.

8A time zone whose central meridian is 75°E is how many hours ahead of UTC?

A.3 hours

B.4 hours

C.5 hours

D.6 hours

Explanation: Earth rotation is 15° of longitude per hour, so 75°E / 15 = UTC+5 (Pakistan Standard Time). Arc-to-time also uses 1° = 4 minutes.

9Local Mean Time (LMT) differs from UTC by approximately:

A.The standard zone offset only, regardless of exact longitude

B.Fifteen minutes for every degree of longitude

C.Four minutes for every degree of longitude from Greenwich (add if east, subtract if west)

D.One hour for every degree of longitude

Explanation: LMT adjusts UTC by 4 minutes per degree of longitude: add east of Greenwich, subtract west. Zone time uses the zone central meridian; LMT uses the actual longitude for sunrise/sunset work.

10Earth convergency between two meridians separated by Δlong at mean latitude φ is:

A.Δlong × cos φ

B.Δlong × tan φ

C.Δlong × sin φ

D.Always identical to the conversion angle

Explanation: Convergency = Δlong × sin(mean latitude). It is the angle between meridians and feeds chart work and great-circle track change. Conversion angle is about half of convergency.

About the PCAA Navigation Exam

PCAA Navigation is the air-navigation theory paper for Pakistan pilot licensing. It covers form of the Earth, time, magnetism and compasses, aeronautical charts, dead reckoning and the triangle of velocities, in-flight corrections (including the 1-in-60 rule), ground-based radio aids (NDB, VOR, DME, ILS, radar/SSR), and GNSS/RNAV/PBN concepts. PCAA flight-crew exams are computer-based via CAAi/Aspeq and aligned with UK/European syllabi such as UK CAA 060 Navigation learning objectives.

Assessment

Computer-based multiple-choice theoretical knowledge examination in Navigation for PCAA pilot licensing (PPL/CPL/ATPL subject paper as applicable). Exams are delivered through the CAAi/Aspeq system under PCAA oversight, using banks aligned with UK/European standards and PCAA national requirements. Approved navigation computer, plotter and non-programmable calculator rules follow the invigilator instructions for your sitting.

Time Limit

Set by PCAA for the licence level and shown at booking on the PCAA/Aspeq exam portal. Confirm the exact duration when you schedule Navigation.

Passing Score

Aligned with UK/European Part-FCL practice at 75% per subject for CAAi-delivered PCAA flight-crew theory exams; confirm the exact mark stated in the current PCAA technical-examinations ANO/candidate instructions for your paper.

Exam Fee

PCAA Navigation Study Tips from Top Performers

1Drill the 1-in-60 rule until track error and double-track-error heading changes are automatic, then practise the same problems with a flight computer for GS and ETA revision.

2For every chart question, state whether you are dealing with a rhumb line or great circle and which projection property applies (Mercator straight rhumb lines; Lambert near-straight great circles between standard parallels).

3Build a one-page radio-aids error sheet: NDB night/coastal/quadrantal, VOR cone of confusion, DME slant range, and ILS localizer versus glide path—then cross-check with GNSS RAIM/SBAS limitations.
