IFR En Route Procedures

Question 1

Delineate Lo and Hi Enroute charts

Answer 1

Lo En Route charts are surface up to BUT NOT INCLUDING 18,000 feet

High En Route charts are from 18,000 and higher

Question 2

At what altitude do we switch from saying “feet” and start saying Flight Levels?

Answer 2

18,000 feet

E.g., 18,000 feet becomes FL180 in standard pressure region.

Question 3

Standard Pressure Region

Answer 3

airspace that includes the Northern Domestic Airspace and all airspace above 18,000ft within the Southern Domestic Airspace.

When flying in the Standard Pressure Region, your altimeter is set to 29.92 in Hg and all altitudes are expressed as “flight levels.”

Question 4

DCPC

Answer 4

Direct Controller Pilot Communication

Is when the pilot is talking directly to a controller.

Question 5

When DCPC is not available, you can

Answer 5

Relay through an FSS

Question 6

What does it mean when ATC says “Radar Identified”?

Answer 6

It means that ATC can see you on radar, and that position reports are NOT required

Question 7

What should you say when you are passed to the next controller on an IFR flight?

Answer 7

Edmonton Centre, Mooney Golf Echo Sierra Romeo, one two thousand” (remember to not say twelve - say one two thousand).

Who you are calling
Plane Type
Call sign
Altitude

Question 8

It is mandatory for IFR pilots to have access to the hi or lo appropriate IFR chart in the cockpit during flight (True/False)

Answer 8

True

Question 9

For aircraft that measure speed in knots, what is the IFR speed tolerance? I.e., by how much can you deviate from your filed True Air Speed?

Answer 9

5%

Question 10

For aircraft that measure speed in Mach, what is the IFR speed tolerance? I.e., by how much can you deviate from your filed True Air Speed?

Answer 10

0.01 Mach

Question 11

What is the procedure for a pilot who cannot maintain the filed flight speed?

Answer 11

The pilot is required to notify ATC as soon as possible.

Question 12

What is the procedure for a pilot who cannot maintain the filed flight speed?

Answer 12

The pilot is required to notify ATC as soon as possible.

Question 13

MEA

Answer 13

Minimum En Route Altitude

Question 14

What is the lowest an IFR pilot en route will ever be to the ground?

Answer 14

We will never be lower than 1,000’ AGL within 5nm

(and that’s OUTSIDE of Mountainous Regions)

Question 15

outside Mountainous Regions altitudes must be maintained at least

Answer 15

1,000’ AGL within 5 nm and Temperature Corrections must be applied.

Question 16

In Mountainous Regions, what are altitude minimums?

Answer 16

1 & 5 require 2,000’
2, 3, 4 require 1,500’

Everywhere else is 1,000’

Question 17

What is “Minimum IFR Altitude”?

Answer 17

May include:
Minimum en route altitude (MEA)

Minimum obstruction clearance altitude (MOCA)

Minimum Sector Altitude

100 nm safe altitude

Area Minimum Altitude (AMA)

Minimum Vectoring Altitude (pilots never see this, but ATC knows it)

Question 18

Exceptions to Minimum IFR altitude on Airways

Answer 18

On Airways: ATC may not “clear” an aircraft below MEA.

ATC may “approve” flight below MEA, but never below MOCA when requested by pilot

Question 19

Under what situation may a pilot request to fly below the MEA but above MOCA?

Answer 19

Icing or Turbulance

To conduct a flight check

MEDEVAC

Navigating using GNSS

Question 20

Surprisingly, MEA is not based on Radar Coverage or Communication coverage. It’s based on

Answer 20

The ability to connect to ground based navigation aids.

Question 21

MOCA

Answer 21

Minimum obstacle clearance altitude

This takes into accounts mountainous regions so we don’t have to adjust the MOCA

Question 22

Cold Temperature Correction is not applied when

Answer 22

Being radar vectored (ATC has already factored in cold temps)

Question 23

IFR Position Reports are used in

Answer 23

Areas with poor radar coverage.

Question 24

What’s included in a Position Report?

Answer 24

call sign

Aircraft position

Time over reporting point in UTC

Altitude or flight level
IFR or controlled VFR

Name of next designated reporting point and ETA

Name only of next designated reporting point

Other information

Question 25

When operating in designated mountainous areas, the pilot must add the appropriate amount of altitude over the published
MOCA. (True/False)

Answer 25

False - the MOCA published in the IFR charts already account for existing in a mountainous region. Do not add corrections to the MOCA.

Question 26

What is 1,000 on Top IFR

Answer 26

Yuen request from the pilot, ATC may provide a clearance to change cruising altitude to remain 1000 feet or more above the cloud layer
