We’ve put together a guide on how to study like a pro, focusing on high-retention techniques that actually work for complex subjects. Read: Learn Faster, Recall More: 10 Steps to Smarter Studying.

Question 1: Groundspeed Calculation — Distance vs Time Analysis

Question ID AIR-243542: An aircraft has to fly a distance of 123 NM. The planned time to cover this distance is 93 minutes. Actually, it covers the distance in 41 minutes. How fast did the aircraft fly?

1. 160 kts

2. 180 kts

3. 142 kts

4. 79 kts

Correct Answer: 180 kt

Explanation

This question is designed to test a quick mental technique: the speed factor.

Instead of using full formulas, divide distance by time: 123 NM ÷ 41 min = 3 NM per minute

Convert to hourly speed: 3 × 60 = 180 kt

This is much faster than the planned speed — which is exactly the point of the question.

Exam Tip

Use speed factor whenever possible:

• 1 NM/min = 60 kt

• 2 NM/min = 120 kt

• 3 NM/min = 180 kt

This saves time both in the exam and in real flying.

Question 2: Lowest IFR Cruising Level — Track, Variation and Heading

Question ID AIR-243412: Determine the lowest suitable ICAO IFR cruise level, given:

Track 185°(T), Variation 5°E and Heading 182° (M).

1. FL 280

2. FL 290

3. FL 300

4. FL 270

Correct Answer: FL280

Explanation

First, convert true track to magnetic track:

• “East is least” → subtract variation

• 185° − 5° = 180° magnetic track

Now apply the semi-circular rules:

Semicircular Rule

• IFR flights use whole thousands of feet

• Magnetic track 180°–359° → EVEN flight levels

• Magnetic track 000°–179° → ODD flight levels

• (VFR uses intermediate +500 ft levels)

Since 180° falls in the 180°–359° sector, an EVEN flight level must be selected.

From the options provided, the lowest suitable even level is FL280

The given heading is irrelevant, this is a common exam distraction. Always use magnetic track.

Semicircular Rule

Exam Tip

• Always convert to magnetic track first

• Ignore heading unless specifically required

• Remember:

  • Eastbound (000–179) → ODD

  • Westbound (180–359) → EVEN

Question 3: True Altitude Calculation — Temperature and Pressure Corrections

Question ID AIR-243685: Given the following information, calculate the true altitude of the aircraft to ensure that Minimum Obstacle Clearance is available (use 30 ft / hPa).

• MOCA: 3700 ft

• Cruise: FL50

• Local aerodrome QNH: 1004 hPa

• Local aerodrome elevation: 1350 ft

• OAT: ISA -15° C

1. 4445 ft

2. 5035 ft

3. 4930 ft

4. 4530 ft

Correct Answer: ≈ 4,530 ft

Explanation

This is a classic altimetry question combining:

• Pressure correction

• Temperature correction

Step 1: Pressure correction

• QNH difference: 1040 vs 1013 → +27 hPa

• 27 × 30 ≈ +270 ft

• Higher pressure → true altitude lower than indicated

So: 5000 ft (FL50) - 270 = 4730 ft QNH

Step 2: Temperature correction

• ISA deviation = −5°C

• “High to low, look out below” → true altitude decreases

Apply 4% rule: Correction ≈ 200 ft decrease

Final: 4730 − 200 ≈ 4530 ft

Exam Tip

• Always subtract aerodrome elevation before temperature correction

• Negative ISA deviation → true altitude decreases

• This topic appears across Performance, Met, and Flight Planning

Question 4: Time to Top of Climb (TOC)

Question ID AIR-243428: Given the following information:

• Departure Airport Elevation:   2 500 feet

• TOC:   FL185

• ROC:   1 500 ft/min

• QNH:   995 hPa

How long does it take to reach TOC? 

1. 10 minutes

2. 11 minutes

3. 12 minutes

4. 9 minutes

Correct Answer: ≈ 10 minutes

Explanation

Step 1: Convert FL to altitude: FL185 = 18,500 ft (pressure altitude)

Step 2: Apply pressure correction

• QNH lower than standard → altitude increases

• Corrected altitude ≈ ~19,000 ft (approx.)

Step 3: Subtract departure elevation: 19,000 − 2,500 = ~16,500 ft climb

Step 4: Calculate time: 16,500 ÷ 1,500 = 11 min (approx.)

Closest answer: 10 minutes

If the question specifies winds at different levels and CAS only then use:

• For descent, use wind and TAS at ½ the altitude change

• For climb use wind and TAS at ⅔ the altitude change (because as we climb higher our RoC decreases with altitude)

Illustrated Example: Climb Performance with QNH Correction.

Exam Tip

• Always convert FL → altitude first

• Then subtract departure elevation

• Watch units:

  • 10.3 min ≠ 10 min 30 sec

  • It’s 10 min 20 sec

Question 5:  LPV Approach — Type of Guidance and Protected Area

Question ID AIR-242871: LPV gives (1)___ guidance with the performance of a localizer, and the protected area is (2)___.

• (1) Lateral; (2) Greater

• (1) Vertical; (2) Greater

• (1) Lateral; (2) Smaller

• (1) Vertical; (2) Smaller

Correct Answer: Localiser-like lateral guidance with vertical guidance; smaller protected area

Explanation

LPV (Localiser Performance with Vertical Guidance) is a GNSS-based approach that provides both:

• Lateral guidance equivalent to a localiser

• Vertical guidance, similar in concept to a glidepath

Although it provides vertical guidance, LPV is not classified as a precision approach. It belongs to the category of APV (Approach with Vertical Guidance).

Key characteristics

• Based on WAAS/GNSS, not ground transmitters

• Can be used at multiple locations without dedicated runway equipment

• Vertical guidance is less sensitive than ILS

Comparison with ILS

• ILS → ground-based (localiser + glide slope transmitters)

• LPV → satellite-based (GNSS)

Protected Area

Because LPV is highly accurate: → The protected area is considerably smaller than for traditional non-precision approaches

Exam Tip

• LPV = “ILS-like”, but not precision

• Think: Localiser performance + vertical guidance (APV)

• Smaller protected area = higher accuracy

Trace the journey of air navigation as we move from legacy ILS systems to the precision of modern GNSS solutions. In the guide From ILS to GNSS: How Modern Air Navigation Works, we break down everything from RNAV and RNP to the latest in GBAS and SBAS technology. We also take a deep dive into the specific Types and Minima of RNP Approaches to help you master the modern cockpit.

Question 6: ICAO Procedure Altitude – Minimum Obstacle Clearance (Doc 8168)

Question ID AIR-243654: ICAO Doc 8168 states that specific altitudes are established for each aerodrome and provide at least 300 m (1000 ft) obstacle clearance within 46 km (25 NM) of the navigation aid, initial approach fix or intermediate fix associated with the approach procedure for that aerodrome. Which of the following abbreviations is used for such altitudes?

1. MCA

2. MEA

3. MSA

4. MOCA

Correct Answer: MSA (Minimum Sector Altitude)

Explanation

According to ICAO Doc 8168 (PANS-OPS) minimum sector altitudes are established for each aerodrome and provide at least 300 m (1,000 ft) obstacle clearance, within 46 km (25 NM). From a navigation aid, initial approach fix (IAF), or intermediate fix

This definition corresponds to the: → MSA — Minimum Sector Altitude

Note

• In newer ICAO editions, 300 m is rounded to 1,000 ft

• Older references may show 984 ft — use 1,000 ft for exams

Key Distinction

• MSA → based on navigation aid / 25 NM radius

• TAA (Terminal Arrival Altitude) → based on approach fixes (e.g. IAF)

Exam Tip

• “25 NM + obstacle clearance” → think MSA

• If the question focuses on approach fixes, consider TAA

• Always link the definition to ICAO Doc 8168

What is the semi-circular rule in ATPL flight planning?

The semi-circular rule assigns cruising levels based on magnetic track:

• 000°–179° → Odd flight levels (IFR)

• 180°–359° → Even flight levels (IFR) VFR flights use the same pattern with an additional 500 ft.

How do you calculate groundspeed in ATPL exams?

Divide distance by time to get NM per minute, then multiply by 60:

• Example: 3 NM/min = 180 kt This “speed factor” method is faster than full formulas.

What affects true altitude in flight planning?

True altitude is affected by:

• Pressure (QNH differences)

• Temperature (ISA deviation)

Cold temperatures reduce true altitude: “High to low, look out below.”

How do you calculate time to top of climb (TOC)?

1. Convert flight level to altitude

2. Apply pressure correction

3. Subtract departure elevation

4. Divide by rate of climb

Adjust for wind if required (use 2/3 climb wind rule).

What is an LPV approach?

LPV (Localiser Performance with Vertical Guidance) is a GNSS-based approach providing:

• Localiser-like lateral guidance

• Vertical guidance (APV, not precision)

It has a smaller protected area due to higher accuracy.

What is Minimum Sector Altitude (MSA)?

MSA provides at least 1,000 ft obstacle clearance, within 25 NM of a navigation aid. Defined in ICAO Doc 8168, it ensures safe terrain clearance around an aerodrome.

Is ATPL Flight Planning a difficult exam?

It’s considered challenging due to time pressure and calculations, but highly predictable. With enough practice and familiarity with question types, it becomes manageable.
