AeroCourse IFR CARs

Question 1

Except during take-off and landing, an IFR aircraft must

Answer 1

fly at an altitude that will ensure obstacle clearance

Question 2

To avoid obstacles in non-mountainous parts of Canada, an IFR aircraft must fly…

Answer 2

at least 1,000’ above the highest obstacle within a 5 nm radius.

Question 3

CARs stands for

Answer 3

Canadian Aviation Regulations

Question 4

Regions 1 and 5 require a minimum obstacle clearance of…

Answer 4

at least 2,000’ above the highest obstacle within a 5 nm radius.

Question 5

Which are the mountainous region numbers

Answer 5

1 and 5

Question 6

Regions 2, 3, and 4 require a minimum obstacle clearance of…

Answer 6

1,500’ above the nearest obstacle within a 5 nm radius.

Question 7

Minimum altitudes for obstacle clearance are based on…

Answer 7

Standard conditions. If non-standard conditions such as large deviations in temperature or pressure exist, the PIC should add to these minimums.

Question 8

AMA

Answer 8

Area Minimum Altitude

Question 8

Area Minimum Altitude will provide ____ feet clearance in non-mountainous regions and ____ feet in mountainous regions

Answer 8

1,000’ and 2,000’

Question 8

How much area does an AMA (usually) cover?

Answer 8

A latitude and longitude grid (1 degree by 1 degree)

Question 9

MEA

Answer 9

Minimum En Route Altitude

Question 10

For where are MEAs established/specified?

Answer 10

All designated low Level Airways and Low Level Air routes in Canada

Question 11

Explain Low Level Air Routes

Answer 11

contained within Class G airspace.

They are basically the same as a low level airway except that they extend upwards from the surface of the earth and are not controlled.

The lateral dimensions are identical to that for a low level airway.

Question 12

Describe Low Level Airways

Answer 12

Controlled airspace classified as Class B or Class E.

Class B extends from 12,501ft or the MEA (whichever is highest), up to 17,999ft ASL.

Class E extends from 2,200ft AGL up to the bottom of the Class B airspace.

Question 13

Define MEA

Answer 13

The published altitude above sea level between specific fixes which assures both acceptable NAVIGATIONAL SIGNAL COVERAGE and

MINIMUM IFR OBSTACLE CLEARANCE

Question 14

MOCA

Answer 14

Minimum Obstruction Clearance Altitude

Question 15

MOCA definition

Answer 15

The lowest altitude allowed for the airway or air route segment at which an IFR flight may be conducted.

Question 16

How much vertical clearance will MOCA provide?

Answer 16

1,000’ above all obstacles lying within the lateral limits of all airways and air routes including those in Mountainous Terrain.

Question 17

When operating in temperatures colder than ISA, pilots should add ____ to the MOCA. Why?

Answer 17

1,000’ because true altitudes will be lower.

Question 18

What happens when the MEA and the MOCA are the same?

Answer 18

Only the MEA will be published.

Question 19

Describe the IFR Separation Flight Levels and Altitudes for East and West direction of flight.

Answer 19

East (0-179 degrees):
Alt: 1,000’, 3,000’, 5,000’
FL: FL190, FL230, FL270
Odd numbers x 1000

West (180 - 359 degrees):
Alt: 2,000’, 4,000’, 6,000’…
FL: FL180, FL200, FL220
Even numbers x 1000

NOTE this rule only applies to RVSM airspace. Above FL290 in non-RVSM airspace, the separation is 2,000’

Question 20

RVSM

Answer 20

Reduced Vertical Separation Minimum

Question 21

Describe RVSM

Answer 21

Previously, IFR flights above 29,000’ (FL290) were separated by 2,000’.

Technology advances allow properly equipped planes to fly at Reduced Vertical Separation Minimum (RVSM) of 1,000’

Question 22

100nm safe altitude: where is it published? What does it achieve?

Answer 22

Published on approach plate

Provides 1,000’ feet of obstacle clearance in ISA conditions within 100 nm.

Question 23

25 nm sector safe altitudes: where are they published, what do they achieve?

Answer 23

Published on Approach Plate, provide 1,000’ of obstacle clearance within 25 nm (OF THE SPECIFIED POINT), shown in quadrants.
