8.2 NM back from threshold, which correlates to 4.3 NM back from the FAF, located at the ZET NDB.

3. Relative to the above question, assuming a ground speed of 120 knots, what should be your target rate of descent to achieve a 3-degree glide path?

635 FPM, interpolate between 110 and 130 in the table.

4. Is an RVR-based Approach Ban a possibility on this approach?

Yes, this runway is equipped with an RVR transmissometer system. For example, note the “RVR 26” in the advisory visibility section in the minima box.

5. If conducting the Localizer approach, what is the minimum FAF crossing altitude when crossing the ZET NDB inbound?

3400 ASL

6. What should be your course of action upon arrival over the ZAB NDB after completing the missed approach procedure prior to proceeding on course, if you are below the minimum safe altitude to proceed on course?

ILS RWY 09

Instrument IQ test

Click the question to see the answer

1. If intending to land on RWY 09, what is the landing distance available?

8,300 feet as noted in the second line in the appropriate box.

2. What minimum ceiling and visibility would you need to achieve a successful landing if completing the ILS 09 Approach; and is an approach ban a possibility on this approach?

A minimum ceiling of 200’ and ½ SM. And yes, an approach ban is a possibility due to the fact that this RWY is RVR equipped as is noted in the minima box (RVR26).

3. To fly this procedure for a straight in approach either via the KAXUG or SATIL transitions, your aircraft must be equipped with:

An IFR certified GPS is required to fly the depicted transitions. Note “GNSS Required” below the text boxes.

4. In the event of a missed approach, what would be your course of action upon arrival at the clearance limit (ATURU) prior to receiving further clearance?

Hold as published at 5000’, via either an offset or parallel entry.

5. The glidepath is U/S and the active approach now reverts to the LOC/DME. You are established inbound on the localizer at 4000. At what point are we legal to commence descent out of 4000?

7.1 DME, note the highlighted box indicating this.

6. Relative to the above question, with your GPS indicating a groundspeed of 120 knots, what should be your target sink rate from 7.1 DME in an effort to fly a constant descent angle (CDA) approach?

With a groundspeed of 120 we interpolate between 110 and 130, and this results in a target descent rate of 635 FPM.

Campbell River, B.C. (CYBL)
Departure Procedures

Instrument IQ test

Click the question to see the answer

1.You are planning to depart RWY 12 at CYBL at a time when the FSS is operating. How is takeoff minimum visibility determined?

Since RWY 12 is runway visual range (RVR) equipped this would be the primary means, followed by the accredited observer. PIC does not qualify as a legal means in this situation.

2.Relative to the above, your initial climb groundspeed is expected to be 100 knots. What initial minimum rate of climb is needed to meet the obstacle clearance criteria?

By referring to the table, this converts to a rate of climb of 435 feet per minute until 600 feet ASL.

3.Relative to the above, what becomes the required climb gradient upon passing through 600 feet ASL?

It now reverts to the standard climb gradient of 200 feet per NM.

4.If your aircraft is unable to realize the above climb gradient, might you still be able to depart RWY 12? If so, by what means?

Yes, we may be able to depart via SPEC VIS.

5.If planning to depart SPEC VIS with a climb speed of 100 KIAS, what minimum ceiling and visibility are required to legally depart?

Minimum ceiling = 1000 feet; Minimum visibility category B = 1½ SM.

6.Is a General Aviation Approach Ban a possibility if conducting an instrument approach to RWY 12?

Localizer Performance with Vertical Glidepath. It is basically the RNAV equivalent of an ILS.

3.Do you expect 24-7 altimeter coverage at CYYJ?

Yes, note the ATIS and LWIS frequencies and the Remote Altimeter Setting Source box is empty, indicating that 24-7 coverage is available at the aerodrome.

4.To do the LPV approach, your GPS must be equipped with ______.

WAAS, or Wide Area Augmentation System. Note the WAAS channel 80200.

5.What is the minimum altitude permitted between DAXET and AGBAR, assuming you've been cleared for the approach, and how much obstacle clearance does it provide?

4)What must the pilot in command do to confirm obstacle clearance when departing RWY 04?

Cross the departure end of the runway by at least 35 feet, make good a minimum climb gradient of 200 FT/NM, no turns below 400 feet above aerodrome elevation (AAE).

5)What is the precise magnetic track of RWY 22?

217 degrees.

6)Your planned climb speed on a SPEC VIS Departure off RWY 22 is 125 KIAS. What minimum ceiling and visibility will allow this departure given the above information?

With this IAS, you are a Category C aircraft and thus require a minimum visibility of two SM and a minimum ceiling of 1,200 feet. You must climb VMC to 2,400 feet ASL and the aerodrome elevation is just over 1,200 feet. The net difference requires a visual climb for 1,200 feet.

7)You would expect the ATIS to operate (limited hours/24-7), please choose.

24-7, no limited hours symbol.

Click the question to see the answer

1)How many distance measuring equipment (DME) sources are indicated on this approach plate?

Two. The VOR/DME 112.1; and adjacent to the threshold of RWY 16 110.3.

2) What minimum altitude would you be legal to descend to after crossing CHUCK on the straight in LOC/DME RWY 16 approach?

6,100 ASL.

3) Is Runway 16 equipped with a runway visual range (RVR) transmissometer?

Negative.

4) Circling minima guarantees a minimum of ____ obstacle clearance when operating at minimum descent altitude (MDA) within the protected manoeuvring area for circling. If manoeuvring at a speed of 105 KIAS, this envelope of protection commences at the runway thresholds and extends for a ___ nautical mile radius.

300 feet; 1.5.

5) Are there any circling restrictions at CYXC?

Yes, note circling restriction, no circling west of extended RWY centreline.

6) If a circling approach became necessary as a Category B aircraft, how would you best determine your time/point to see?

Arrive at MDA (3600) by 1.7 DME (110.3).

Instrument IQ test

Click the question to see the answer

1) 1. Identify the fly-over waypoints within this procedure: _____; _____.

1. RW24; DEMGA.

2) You are cleared for the straight in RNAV RWY 24 approach and are cleared direct to the DARAP waypoint. What would be the correct lateral and vertical profile for this approach after crossing DARAP? It is daytime and +10 degrees C at the time of the approach.

DARAP to SAVAM AT 4200; SAVAM to MAROX at 4100; intercept LPV G/P at MAROX and fly down to Decision Altitude of 2395 ASL.

3) What is the distance between the FAWP to the MAWP?

5.1 NM.

4) You are flying the LNAV approach via CDFA technique. You are level at 4100 ASL. At what point do you initiate descent and what should be the optimum crossing altitude over ADSEG?

Initiate descent at MAROX; 3260 ASL.

5) If your groundspeed on the approach was 110 knots, you would require a minimum descent rate of ____ FPM to meet this target.

680 FPM.

6) What is the clearance limit of this approach and what action should be taken upon arrival if further clearance is not received?

DEMGA; Hold/shuttle as published and be at 5300 prior to proceeding on course.
