1What is the standard alternate aerodrome weather minimum for an IFR helicopter flight if the alternate aerodrome is served by a usable instrument approach procedure?
A.A ceiling of at least 200 feet above the lowest approach minimum (HAT/HAA) and a visibility of at least 1 statute mile, or the lowest approach visibility minimum, whichever is higher.
B.A ceiling of 600 feet and 2 statute miles visibility, or 300 feet ceiling and 1 statute mile above the lowest usable approach minimum, whichever is higher.
C.A ceiling of 800 feet and 2 statute miles visibility, or 300 feet ceiling and 1 statute mile above the lowest usable approach minimum, whichever is higher.
D.A ceiling of at least 400 feet above the lowest approach minimum and a visibility of at least 1.5 statute miles.
Explanation: According to the Canada Air Pilot (CAP) General Pages and TC AIM, the alternate weather minima for a helicopter at an aerodrome with a usable approach are a ceiling of at least 200 feet above the lowest approach minimum (HAT/HAA) and a visibility of at least 1 SM (or the approach minimum, whichever is higher). This helicopter-specific rule recognizes the lower speed and high maneuverability of helicopters compared to aeroplanes.
2An IFR helicopter pilot is planning an alternate aerodrome that has a GNSS approach with a published LNAV minimum descent altitude of 650 feet ASL, a height above touchdown (HAT) of 350 feet, and a minimum visibility of 1.25 statute miles. What is the minimum forecast ceiling and visibility required for this alternate?
A.550 feet ceiling and 1.25 statute miles visibility
B.550 feet ceiling and 1.0 statute mile visibility
C.850 feet ceiling and 1.25 statute miles visibility
D.850 feet ceiling and 2.0 statute miles visibility
Explanation: For helicopters, the alternate minimum is 200 feet above the approach minimums (HAT/HAA) and 1 SM or the approach visibility minimum, whichever is higher. Here, HAT is 350 feet, so 350 + 200 = 550 feet ceiling. The visibility minimum is 1.25 SM, which is higher than the base 1 SM, so 1.25 SM is required. Therefore, the minimum alternate forecast must be a ceiling of 550 feet and 1.25 SM visibility.
3You are planning an IFR flight in a helicopter to an alternate aerodrome that does not have an instrument approach. What is the minimum weather required at the alternate aerodrome at the expected time of arrival?
A.The forecast weather must be no lower than 500 feet above a minimum IFR altitude that will permit a VFR approach and landing.
B.The forecast must indicate a ceiling of at least 800 feet and visibility of at least 2 statute miles.
C.The forecast must indicate a ceiling of at least 1,000 feet and visibility of at least 3 statute miles.
D.The forecast must indicate no clouds below 1,000 feet above the minimum vectoring altitude, and visibility at least 1 statute mile.
Explanation: Per the CAP GEN Alternate Weather Minima Requirements, when no IFR approach is available at the alternate the forecast weather must be no lower than 500 feet above a minimum IFR altitude that will permit a VFR approach and landing. In other words, the ceiling and visibility must let the helicopter descend from the minimum IFR altitude and complete the approach and landing in VMC.
4Under Canadian Aviation Regulations (CAR 602.88), what is the minimum fuel reserve requirement for a helicopter operated under IFR if an alternate aerodrome is specified in the flight plan?
A.30 minutes of fuel at normal cruising speed.
B.45 minutes of fuel at normal cruising speed.
C.30 minutes of fuel at holding speed at 1,500 feet.
D.45 minutes of fuel at holding speed at 1,500 feet.
Explanation: CAR 602.88(4)(b) states that a helicopter operated under IFR with an alternate specified must carry sufficient fuel to fly to the destination, execute an approach and a missed approach, fly to the alternate aerodrome, and then fly for an additional 30 minutes at normal cruising speed. This is equivalent to the fuel reserve requirement for turbo-jet aeroplanes and differs from propeller aeroplanes.
5A helicopter is planning an IFR flight from Vancouver (CYVR) to Victoria (CYYJ). The estimated time enroute to CYVR's alternate (CYYJ) from the destination is 18 minutes. The cruise fuel flow is 360 lbs/hour. If the flight to the destination takes 45 minutes, and you must plan for one approach and missed approach at the destination, what is the minimum regulatory fuel required under CAR 602.88?
A.558 lbs of fuel
B.648 lbs of fuel
C.438 lbs of fuel
D.510 lbs of fuel
Explanation: Fuel required = fuel to destination + fuel to alternate + 30 minutes reserve. Destination fuel = (45 / 60) * 360 = 270 lbs. Alternate fuel = (18 / 60) * 360 = 108 lbs. Reserve fuel = 30 minutes = (30 / 60) * 360 = 180 lbs. Total fuel = 270 + 108 + 180 = 558 lbs. A missed approach fuel allowance is included within flight enroute calculations or extra fuel, but the basic legal elements are destination + alternate + 30 minutes cruise reserve.
6Under CAR 602.88, what is the fuel reserve requirement for a helicopter operated under IFR if NO alternate aerodrome is specified in the flight plan?
A.30 minutes of fuel at normal cruising speed.
B.45 minutes of fuel at normal cruising speed.
C.20 minutes of fuel at normal cruising speed.
D.30 minutes of fuel at holding speed at 1,500 feet.
Explanation: Under CAR 602.88(4)(b), a helicopter is grouped with turbo-jet aeroplanes: it must carry fuel to fly to the destination, execute an approach and a missed approach, and then fly for an additional 30 minutes at normal cruising speed. This 30-minute reserve applies whether or not an alternate is specified — subparagraphs (i) and (ii) both require 30 minutes, so the reserve does not increase to 45 minutes when no alternate is filed.
7Under Canadian Aviation Regulations (CAR 602.129), what weather metric is the primary governing factor that imposes an approach ban on a helicopter?
A.Runway Visual Range (RVR) reports.
B.Reported ground visibility from a METAR.
C.Tower visibility reports.
D.Pilot-observed flight visibility.
Explanation: Under CAR 602.129, only Runway Visual Range (RVR) reports impose an approach ban on helicopters. Ground visibility reports do not prevent a helicopter pilot from commencing or continuing an approach, provided that if RVR is reported, it is at or above the minimum (typically 1,200 feet RVR).
8A helicopter pilot is conducting an instrument approach. A weather report is received stating that the Runway Visual Range (RVR) for the landing runway is 1,000 feet. However, the reported ground visibility is 1/2 statute mile. May the pilot legally continue the approach past the Final Approach Fix (FAF)?
A.Yes, because the reported ground visibility is at least one-quarter (1/4) of a mile, which is a regulatory exception allowing the approach to continue.
B.No, because the RVR is below the minimum of 1,200 feet, which is an absolute ban for helicopters regardless of ground visibility.
C.Yes, because helicopters are completely exempt from all approach bans in Canada.
D.No, because the ground visibility must be at least 1 statute mile when the RVR is below 1,200 feet.
Explanation: Under CAR 602.129, a helicopter approach ban is active when RVR is below 1,200 feet. However, a specific exception exists: if the RVR is less than the minimum but the reported ground visibility is at least 1/4 SM, the pilot may continue the approach. Since the ground visibility is 1/2 SM (which is greater than 1/4 SM), the pilot may legally continue past the FAF.
9What is the minimum Runway Visual Range (RVR) required to avoid an approach ban for a helicopter on a standard instrument approach in Canada, in the absence of a ground visibility exception?
A.1,200 feet (RVR A)
B.1,600 feet (RVR A)
C.2,600 feet (RVR A)
D.600 feet (RVR A)
Explanation: For helicopters, the approach ban limit is a reported Runway Visual Range (RVR) of less than 1,200 feet (RVR A). If the reported RVR is 1,200 feet or more, the approach may be commenced and continued.
10To maintain currency to act as pilot-in-command of a helicopter under IFR, what recency requirements must be met within the 6 months preceding the flight?
A.6 hours of instrument time and 6 instrument approaches in an aircraft or approved simulator.
B.6 hours of instrument time and 12 instrument approaches in an aircraft or approved simulator.
C.10 hours of instrument time and 6 instrument approaches in an aircraft only.
D.3 hours of instrument time and 3 instrument approaches in a helicopter.
Explanation: Under CAR 401.05(2), a pilot must not act as pilot-in-command or co-pilot of an aircraft under IFR unless they have completed, within the 6 months preceding the flight, at least 6 hours of instrument time, and 6 instrument approaches under actual or simulated instrument conditions.

About the INRAT-H Exam

The Transport Canada Instrument Rating - Helicopter (INRAT-H) written examination tests the theoretical knowledge required to command a helicopter under Instrument Flight Rules (IFR) in Canada. The exam covers four key areas: Air Law, Meteorology, Navigation Aids/Communications, and Human Factors/Airmanship. It features a mix of general knowledge questions and flight planning questions requiring pilots to interpret charts (CAP, CFS, LO/LO-HI charts), calculate wind corrections, descent profiles, and apply specific helicopter regulations such as 30-minute reserve fuel, 200'-1SM alternate minima, and RVR approach bans.

INRAT-H Study Tips from Top Performers

1Memorize the helicopter-specific alternate minima (200' HAT/HAA above approach minimum and 1 SM visibility, whichever is higher).
2Understand the difference in IFR fuel reserves (30 minutes for helicopters with alternate vs 45 minutes for propeller aeroplanes).
3Be proficient in decoding GFAs, TAFs, and METARs, including wind shear and TEMPO/PROB conditions.
4Understand standard holding entry sectors (Direct, Parallel, Teardrop) based on your inbound heading relative to the holding fix.
5Know the cold temperature altimeter correction formula and when it must be applied to approach altitudes.
6Understand the features of Category A approaches, and remember that rotorcraft are always Category A (speed up to 90 KIAS) unless operating at higher speeds.
7Study spatial disorientation illusions specific to helicopters, such as flicker vertigo from light passing through rotor blades and somatogravic illusion.

Frequently Asked Questions

What is the passing score and format of the INRAT-H?

The INRAT-H exam consists of 50 multiple-choice questions. The passing score is 70%, which means you must answer at least 35 questions correctly. You are given 3 hours to complete the examination.

How does the helicopter fuel requirement differ from aeroplanes under IFR?

Under CAR 602.88, an IFR helicopter requires a 30-minute fuel reserve at normal cruising speed when an alternate is specified (similar to turbo-jets), whereas a propeller-driven aeroplane requires a 45-minute reserve.

What are the Canadian alternate aerodrome weather requirements for helicopters?

According to CAP GEN, if an instrument approach is available at the alternate, the weather minima are a ceiling of at least 200 feet above the lowest approach minimum (HAT/HAA) and a visibility of at least 1 SM (or the lowest approach visibility minimum, whichever is higher).

What is the approach ban rule for helicopters under CAR 602.129?

For helicopters, only Runway Visual Range (RVR) reports impose an approach ban. In the absence of an RVR report, or if ground visibility is reported as at least 1/4 SM, the approach ban does not prevent the helicopter from initiating or continuing the approach.

What tools can I use during the INRAT-H exam?

You are required to bring standard flight planning tools, including a manual flight computer (E6B or CX-3 electronic flight computer), a protractor, a ruler, and pencil/eraser. Transport Canada provides the required reference material booklet during the test.
