Section 10.1.2 (ebook section 10.2) - Circling Approaches

The basic (standard) circling approach radii have not changed, but an additional category known as the "expanded" circling approach radii has been created.

If you see a white "C" on a black square, like the one below for the Kamloops, that means that the expanded circling approach radii apply.

The expanded circling minima are based on the aircraft category (just like the standard circling radii), but also include the circling MDA ALTITUDE. This is to account for the increased true airspeed associated with higher altitudes. Note that some categories, like category C radii, are substantially larger than what you would get if you only take into account the higher true airspeed.

Note! To see which circling radii to use, both altitudes must be either uncorrected for temperature, or they must both be corrected for cold temperature (i.e. so you are comparing apples to apples). Remember, you're comparing the MDA altitude from the approach chart and the MDA altitude from the expanded circling approach radii.

Section 12.1.1 (Section 11.1.1 in 2024 edition) - IFR Communication Failure

The flow chart indicating the priority for selecting your routing after having a communication failure while under IFR was incorrect. The correct version is shown below:

Section 14 - INRAT Sample Exam, Question 38 (ebook C25-038)

To solve this question correctly, you need to know that you are flying in a piston single engine aircraft.
