7  ATPL Air Law Exam Questions Covered in This Blog

• AIR-236263: Minimum Sector Altitude (MSA) — Minimum Obstacle Clearance (MOC)

• AIR-236866: TCAS Logic — Why a Traffic Advisory (TA) Precedes a Resolution Advisory (RA)

• AIR-235768: Flight Information Region (FIR) — Included Airspace Types

• AIR-235732: Radar Vectoring — Maximum Intercept Angle for ILS Localiser

• AIR-235867: Minimum Height — Over Congested Areas (ICAO Rules)

Question 1: Minimum Sector Altitude (MSA)

Question ID AIR-236263: The MOC (The Minimum Obstacle Clearance)  of a MSA (Minimum Sector Altitude)  is...

1. 1000 ft

2. 1000 m

3. 500 m

4. 500 ft

Correct Answer: 1,000 ft

Explanation

The MSA guarantees at least 1,000 ft obstacle clearance within a radius of 25 NM (46 km), typically centred on a navigation aid or aerodrome reference point.

In practice, MSAs are often divided into sectors. Each sector provides its own minimum altitude based on terrain.  For example, higher terrain on one side of an aerodrome results in a higher sector MSA.

A common source of confusion is mixing MSA with other IFR altitudes:

• MSA: 1,000 ft clearance within 25 NM

• TAA (Terminal Arrival Area): similar concept, but centred on a specific fix (e.g. IAF), not the aerodrome

Exam Tip:  If you see MSA, think immediately:  “25 NM → 1,000 ft clearance.”

Question 2: TCAS Logic — TA vs RA

Question AIR-236866: According to ICAO Pans Ops 8168 a Traffic Advisory (TA) should precede a Resolution Advisory (RA) because:

1. TAs have the ability to create a horizontal traffic avoidance manoeuvre

2. A TA will highlight the approximate position of an aircraft nearby that may become an RA

3. A TA must always be created before an RA

4. TAs have the ability to create a vertical traffic avoidance manoeuvre

Correct Answer: A TA will highlight the approximate position of an aircraft nearby that may become an RA. 

Explanation

A Traffic Advisory (TA) is an awareness tool. It alerts the crew to nearby traffic that may become a threat.

A Resolution Advisory (RA), on the other hand, requires immediate action.

Typical timing:

• TA: triggered ~40 seconds before potential conflict

• RA: triggered ~25 seconds before conflict

In most cases, the TA comes first to prepare the crew. However, if closure rates are high, an RA may be issued without a prior TA.

Key point:

• TA → “Heads up” – no manoeuvre required

• RA → “Act now” – follow immediately

Question 3: Flight Information Region (FIR) 

Question ID AIR-235768: Which types of airspace are included within a Flight Information Region (FIR)?

1. Most types of controlled airspace, excluding control zones (CTRs).

2. Most types of controlled airspace, excluding restricted areas.

3. All types of controlled airspace.

4. All types of controlled airspace below 10000 ft, other types are included in a UIR.

Correct Answer: All types of controlled airspace.

Explanation

 An FIR is essentially the entire airspace of a state (or part of it) where flight information and alerting services are provided.

Within an FIR, you can find controlled airspace (CTR, TMA, airways), uncontrolled airspace, and multiple airspace classes (A–G).

Not every FIR contains all airspace classes, but it can include any combination.

A key operational role of FIRs is Search and Rescue (SAR) responsibility. An FIR covers every part of the world for this reason.

Exam Tip: Think of an FIR as a container:  It includes everything — not just controlled airspace.

Question 4: ILS Localiser Intercept Angles

Question ID AIR-235732: According to ICAO Doc 4444, when an aircraft is radar vectored to an ILS localiser course, the angle between the interception course and the localiser course shall not be larger than…

1. 35 degrees.

2. 50 degrees.

3. 45 degrees.

4. 40 degrees.

 What is the maximum intercept angle when radar vectoring an aircraft to the ILS localiser?

Correct Answer:  45° (general case)

Explanation

 According to ICAO procedures:

• Standard vectoring: ≤ 45° intercept

• Independent parallel approaches: ≤ 30° intercept

A larger intercept angle increases the risk of overshooting the localiser, especially in manual flight.

Additional operational numbers worth remembering:

• ≥ 2 NM before final approach fix: stabilisation margin

• ≤ 4 NM from runway: no further speed control instructions

Exam Tip: Memorise the trio 45° – 30° – 4 NM  (Intercept / Parallel / Speed control limit)

Question 5: Minimum Height Over Congested Areas

Question ID AIR-235867:  Except when necessary for take-off or landing, or except by permission from the appropriate authority, what is the minimum height to be maintained by an aircraft over the congested areas of cities, towns or settlements?

1. 100 m over the highest man-made obstacle located within a radius of 600 m from the position of the aircraft.

2. 300 ft over the highest obstacle, located within a radius of 600 m from the position of the aircraft.

3. 600 ft over the highest obstacle located within a radius of 300 m from the position of the aircraft.

4. a height that will permit an emergency landing to be made without undue hazard to persons or property

Correct Answer: A height that will permit an emergency landing to be made without undue hazard to persons or property.

Explanation

ICAO defines the rule broadly: You must always maintain a height that allows a safe emergency landing.

EASA builds on this with specific VFR minima:

• 1,000 ft above the highest obstacle within 600 m (congested areas)

• 500 ft (non-congested areas)

If these minima are not sufficient to ensure a safe forced landing, you must fly higher.

Exam Tip: Two layers to remember:

1. ICAO principle → safe emergency landing

2. EASA minima → 1,000 ft / 500 ft

Always apply the more conservative option.

Question 6: Altimeter Setting Procedures

Question ID AIR-237065: An aircraft has been instructed to descend from FL330 to FL110/11 000 ft altitude. When should the pilot change to QNH?

1. When the clearance has been given, and the aircraft is inside the protected area.

2. When the clearance has been given, and the aircraft is not jeopardising the upper FLs.

3. When the clearance has been given from the local ATS/ATC.

4. At the pilot's discretion.

Correct Answer: When the clearance has been given from the local ATS/ATC.

Explanation

Legally, the change can be made as soon as clearance to an altitude is issued.

Operationally, pilots usually wait until approaching the transition level to avoid unnecessary switching and maintain consistent vertical separation.

Key principle:

• Standard pressure (1013) → traffic separation

• QNH → terrain clearance

Also note: If QNH is significantly lower than standard, the aircraft may descend more than expected after switching.

Exam Tip: Law vs practice.

• Law: change immediately when cleared

• Reality: change near the transition level

Question 7: Missed Approach Before MAPt

Question ID AIR-236792:  If a missed approach is initiated prior to reaching the MAPt, what should the pilot do?

1. If above the MSA, turn to the IAF for the subsequent approach.

2. Proceed to that point and then follow the procedure.

3. Maintain runway track and wait for ATC instructions.

4. Climb straight ahead until over the MAPt and request radar vectors.

Correct Answer: Proceed to that point and then follow the procedure.

Explanation

Even if you decide to go around early, the procedure remains structured:

1. Continue to the Missed Approach Point (MAPt)

2. Then execute the published missed approach

Why? Because obstacle clearance and traffic separation are based on that defined path.

Modern procedures often use CDFA (Continuous Descent Final Approach) with a Decision Altitude (DA), reducing reliance on MAPt, but the principle still applies.

Exam Tip: Early go-around does not mean improvisation. → Always rejoin the published procedure via MAPt.

Explore key subtopics & core concepts of the Air Law Syllabus. 

Air Law focuses on the international rules, procedures, and regulations that standardise aviation worldwide. The syllabus covers areas such as airspace structure, licensing, operational procedures, airport markings, and the legal framework behind everyday flight operations.

Unlike calculation-heavy ATPL subjects, Air Law is primarily a memory-based exam. Consistent question-bank practice is therefore one of the most effective preparation methods, especially since many real exam questions closely resemble those in the Airhead ATPL Question Bank.

The key to success is repetition. Regular practice helps you identify weak areas, improve recall speed, and build confidence with the wording and logic commonly used in EASA exams. Some students prefer making concise notes, while others rely almost entirely on repeated question practise. Both approaches can work well when combined with steady revision.

💡 Study Tip: Treat Air Law like learning a new language: short, frequent revision sessions are far more effective than last-minute cramming. Focus on recognising patterns, remembering exact wording, and understanding the logic behind the rules.
