1Under MCAR-Part-FCL FCL.615, which subject set is required for Instrument Rating (IR) theoretical knowledge examinations?

A.Air law; aircraft general knowledge — instrumentation; flight planning and monitoring; human performance; meteorology; radio navigation; communications

B.Only air law, meteorology, and operational procedures

C.Principles of flight, mass and balance, and performance only

D.Human performance, aircraft general knowledge — airframe/systems/powerplant, and VFR communications only

Explanation: MCAR-Part-FCL FCL.615(b) requires IR theoretical knowledge in seven subjects: air law; aircraft general knowledge — instrumentation; flight planning and monitoring; human performance; meteorology; radio navigation; and communications. This free bank is an English MCQ study adaptation for theory only, not the IR skill test (DCA-PEL-09).

2According to MCAR-Part-FCL FCL.025, what is the minimum pass mark for each IR theoretical knowledge examination paper?

A.50% of the marks allocated to the paper

B.65% of the marks allocated to the paper

C.75% of the marks allocated to the paper

D.90% of the marks allocated to the paper

Explanation: FCL.025 requires a candidate to achieve at least 75% of the marks allocated to each theoretical knowledge examination paper. There is no penalty marking for incorrect answers.

3Under FCL.025, how long after completing the full set of IR theoretical knowledge examinations does that success remain valid for the issue of an instrument rating?

A.12 months from the date of the first paper passed

B.18 months from the end of the calendar month of the first attempt

C.36 months for the issue of an instrument rating

D.Indefinitely once all papers are passed

Explanation: Under FCL.025, successful completion of the theoretical knowledge examinations remains valid for the issue of an instrument rating for 36 months. Separately, all required papers must be passed within an 18-month window from the end of the calendar month of the first attempt.

4Under MCAR-Part-FCL FCL.605, what is the standard minimum decision height associated with IR privileges unless a lower height is authorised under MCAR-Part-SPA?

A.100 ft (30 m)

B.200 ft (60 m)

C.300 ft (90 m)

D.500 ft (150 m)

Explanation: FCL.605 grants IR privileges for flight under IFR, including PBN operations, with a minimum decision height of no less than 200 ft (60 m). Lower minima require authorisation under MCAR-Part-SPA.

5According to MCAR-Part-FCL FCL.610, which licence and experience combination meets the basic prerequisites for commencing IR training (aeroplane category, day IR)?

A.Student pilot licence only, with no PIC cross-country time

B.At least a PPL (or CPL) in the appropriate category and at least 50 hours cross-country PIC time with the category minima stated in FCL.610

C.ATPL theory credit only, with no flight experience required

D.Night rating only, without a PPL or CPL

Explanation: FCL.610 requires applicants to hold at least a PPL in the appropriate category (with night privileges if IR privileges will be used at night) or a CPL, plus at least 50 hours cross-country PIC time with the stated category minima (e.g., at least 10 hours in the relevant aeroplane category).

6Under MCAR-Part-FCL FCL.055(d), what additional language requirement applies specifically to holders of an instrument rating?

A.No language requirement applies beyond the general licence endorsement

B.They must have demonstrated the ability to use the English language for radiotelephony and flight-related communication in all phases of flight

C.They must be proficient in at least two languages other than English

D.They must demonstrate expert level (Level 6) in the local national language

Explanation: FCL.055(d) adds an English-specific requirement for IR holders. Without prejudice to the general endorsement, they must have demonstrated the ability to understand all information relevant to all phases of flight including preparation, to use radiotelephony in all phases including emergencies, and to communicate with other crew members. This is why instrument operations rely on English internationally.

7Under FCL.025, all required IR theoretical knowledge papers must be passed within what period measured from the end of the calendar month of the first attempt?

A.6 months

B.12 months

C.18 months

D.36 months

Explanation: FCL.025 requires that all theoretical knowledge examination papers be completed within an 18-month period counted from the end of the calendar month when the applicant first attempted an examination. The 36-month figure applies to validity for IR issue after the full set is passed.

8In controlled airspace, when may a pilot legally commence a published instrument approach procedure?

A.Whenever the aircraft is within 50 NM of the destination, regardless of ATC clearance

B.Only after receiving approach clearance (or being cleared via a route that authorises joining the procedure) as applicable in controlled airspace

C.Only after the runway is in sight and a visual circuit can be joined

D.Only after the missed approach point has been passed

Explanation: In controlled airspace, instrument approaches are flown under ATC clearance. The pilot may commence the published procedure when cleared for the approach or when cleared via a routing that authorises joining it. Visual contact is not required to start an instrument approach.

9What is the relationship between filing an IFR flight plan and receiving an IFR clearance?

A.An IFR flight plan is a request for ATS services; the pilot still requires an IFR clearance before operating IFR in controlled airspace

B.Filing a flight plan automatically constitutes a clearance to enter controlled airspace IFR

C.Only VFR flights require a filed flight plan; IFR needs only a radio call

D.Once the flight plan is filed, no further ATC communication is required until landing

Explanation: An IFR flight plan requests ATS services and provides essential data, but operating IFR in controlled airspace requires a specific ATC clearance. The clearance may amend route, altitude, or other elements of the filed plan.

10Unless a higher or lower speed is published or authorised, what is the maximum indicated airspeed for a standard ICAO holding pattern at or below 14,000 ft?

A.170 kt IAS

B.230 kt IAS

C.265 kt IAS

D.280 kt IAS

Explanation: ICAO Doc 8168 holding criteria use a maximum holding speed of 230 kt IAS at or below 14,000 ft (unless restricted by procedure notes or ATC). Higher altitude bands have higher maximum speeds.

About the Mauritius DCA IR Theory Exam

The Mauritius DCA Instrument Rating theoretical knowledge examination is the ground assessment required under MCAR-Part-FCL FCL.615 before IR flight instruction completion and skill test.
