1What is the minimum fuel reserve required for an IFR flight when no alternate is required?

A.30 minutes beyond the planned flight time at normal cruise speed

B.45 minutes beyond the planned flight time at normal cruise speed

C.Fuel to fly to the destination, then to the alternate, plus 45 minutes

D.Fuel to fly to the destination at cruise power for 1 hour

Explanation: According to 14 CFR 91.151, for IFR flights, no person may begin a flight unless the aircraft carries enough fuel (considering wind and forecast weather) to complete the flight to the first airport of intended landing and fly thereafter for at least 45 minutes at normal cruising speed. This is different from VFR which only requires 30 minutes for day flights.

2Under what conditions is an alternate airport required for an IFR flight?

A.For all IFR flights regardless of weather conditions

B.When the weather at the destination is below landing minimums at the ETA

C.When weather conditions at the destination are at or above 2,000-foot ceiling and 3 statute miles visibility

D.Only when flying in Class A airspace

Explanation: Under 14 CFR 91.169, an alternate airport is required when the weather conditions at the destination airport at the ETA are forecast to be below the alternate minimums. The standard alternate minimums are 600-2 for precision approaches and 800-2 for non-precision approaches, but an alternate is always required when destination weather is below published landing minimums.

3What are the standard alternate airport minimums for an airport with a precision approach?

A.300-foot ceiling and 1 statute mile visibility

B.400-foot ceiling and 2 statute miles visibility

C.600-foot ceiling and 2 statute miles visibility

D.800-foot ceiling and 2 statute miles visibility

Explanation: The standard IFR alternate minimums for airports with at least one precision approach (ILS, GLS, LPV with DA) are 600-foot ceiling and 2 statute miles visibility. For airports with only non-precision approaches, the standard minimums are 800-foot ceiling and 2 statute miles visibility. These values can be raised by the FAA in the chart supplement if required.

4A pilot plans to fly IFR from ABC to XYZ. The forecast at XYZ at ETA is: ceiling 1,500 feet broken, visibility 4 miles. XYZ has an ILS approach with minimums of 200-1/2. Is an alternate required?

A.Yes, because the ceiling is below 2,000 feet

B.Yes, because visibility is less than 5 miles

C.No, because both ceiling and visibility are forecast to be above landing minimums

D.Yes, because the ceiling is below 3,000 feet

Explanation: An alternate is only required when weather at the destination is forecast to be below published landing minimums. In this case, the ceiling (1,500 feet) and visibility (4 miles) are both well above the ILS minimums of 200-1/2. The standard 1-2-3 rule (ceiling 2,000/visibility 3 miles) is a planning guideline, not a regulatory requirement.

5When selecting an alternate airport, what minimums apply if the airport has only a VOR approach?

A.200-foot ceiling and 1/2 mile visibility

B.600-foot ceiling and 2 statute miles visibility

C.800-foot ceiling and 2 statute miles visibility

D.1,000-foot ceiling and 3 statute miles visibility

Explanation: For airports with only non-precision approaches (VOR, NDB, LOC, etc.), the standard IFR alternate minimums are 800-foot ceiling and 2 statute miles visibility. Precision approaches (ILS, GLS, LPV with vertical guidance) qualify for 600-2 minimums. Always check the chart supplement as these minimums may be raised by NOTAM or local directives.

6What weather information should a pilot consider when planning an IFR cross-country flight?

A.Only the destination airport METAR

B.Weather charts, METARs, TAFs, SIGMETs, AIRMETs, and PIREPs along the entire route

C.Only the TAF for the departure and destination airports

D.Only surface analysis charts

Explanation: IFR flight planning requires comprehensive weather analysis including surface analysis charts, constant pressure charts, significant weather prognostic charts, METARs, TAFs, SIGMETs, AIRMETs, and PIREPs. Pilots must check weather along the entire route of flight, not just at departure and destination, to identify hazards like thunderstorms, icing, turbulence, and wind shear.

7When must a pilot select an alternate airport that has a precision approach?

A.For all IFR flights

B.When the destination has only non-precision approaches available

C.When the destination weather is forecast to be below precision approach minimums

D.A pilot is never required to use an alternate with a precision approach

Explanation: There is no regulatory requirement to select an alternate with a precision approach. The alternate airport only needs to have an approach procedure that the pilot is qualified to use and that is expected to be operational at the ETA. However, selecting an alternate with precision approaches may provide better weather minimums (600-2 vs 800-2).

8What is the purpose of a VOR equipment check before an IFR flight?

A.To verify the VOR receiver meets the 14 CFR 91.171 accuracy requirements

B.To check the audio quality of the identifier

C.To test the DME function

D.To verify GPS accuracy

Explanation: 14 CFR 91.171 requires that VOR equipment be checked for accuracy within the preceding 30 days before IFR flight. The maximum permissible error is plus or minus 4 degrees. This can be accomplished using a VOR test facility (VOT), a ground checkpoint, a dual VOR cross-check, or comparing against a known accurate receiver.

9A VOR receiver check using a VOT indicates the bearing is 180° TO. What is the acceptable range?

A.176° to 184°

B.178° to 182°

C.175° to 185°

D.170° to 190°

Explanation: When using a VOR test facility (VOT), the CDI should center with a FROM indication on the 180° radial (or TO indication on the 360° radial) with plus or minus 4 degrees error. For a VOT bearing of 180° TO, the acceptable range is 176° to 184° (180° ± 4°).

10What altitude should be selected for an IFR flight in Class A airspace?

A.Any altitude the pilot requests

B.The altitude assigned by ATC

C.The MEA of the airway being flown

D.FL180 or above

Explanation: In Class A airspace (above 18,000 feet MSL to FL600), pilots must operate on an IFR flight plan and on an ATC clearance. All altitudes are assigned by ATC; pilots cannot select their own cruising altitude. ATC will assign altitudes that meet minimum en route altitude (MEA) requirements and provide separation from other traffic.

Frequently Asked Questions

How many questions are on the Instrument Rating knowledge test?

The FAA Instrument Rating Airplane (IRA) knowledge test contains 60 multiple-choice questions. You have 2.5 hours to complete the exam and need 70% (42 correct answers) to pass. The exam is administered at PSI testing centers.

What is the Instrument Rating knowledge test pass rate?

The FAA IRA knowledge test has an estimated pass rate of 75-85% for first-time test-takers. The exam tests IFR procedures, weather, navigation, and approach procedures. With thorough ground study and 200+ practice questions, most well-prepared candidates pass on the first attempt.

What are the aeronautical experience requirements for an Instrument Rating?

To earn an instrument rating, you need: 1) 50 hours of cross-country PIC time (minimum 10 hours in airplanes), 2) 40 hours of actual or simulated instrument time, 3) A 250 NM cross-country flight under IFR with 3 different approaches at 3 airports, 4) An instructor endorsement for the knowledge test and practical test. Training through Part 141 programs may have reduced hour requirements.

How long should I study for the Instrument Rating knowledge test?

Plan for 40-60 hours of dedicated ground study over 4-6 weeks. Focus on IFR regulations, weather theory, instrument approach procedures, and navigation. The FAA Instrument Flying Handbook and Instrument Procedures Handbook are essential study references. Complete at least 200 practice questions and aim for 80%+ consistently before scheduling your exam.

What does the lost communication rule (91.185) require?

If you lose radio communications while IFR, you should: 1) Set transponder to 7600, 2) Continue the route: assigned → vectored → expected → filed, 3) Continue at the altitude: assigned → expected → MEA (whichever is highest), 4) Leave the clearance limit: if you have an approach, begin the approach at the EFC time or the ETA from the filed flight plan (whichever is later). Remember the acronym: AVE-F for route (Assigned, Vectored, Expected, Filed).

What instrument currency is required to fly IFR?

To act as PIC under IFR, you must have performed and logged within the preceding 6 calendar months: 6 instrument approaches, holding procedures and tasks, and intercepting/tracking courses through the use of navigational electronic systems. If currency lapses, you must complete an instrument proficiency check (IPC) with an authorized instructor or examiner.
