The enroute phase of flight includes all your flight activities from the time you level off at enroute altitude
until you initiate an approach at your destination.
Level off at enroute altitude at optimum cruise, IMN for cruise altitude. Use the fuel chart found in Figure
12 for cruise settings.
ENROUTE COMMUNICATION PROCEDURES
Enroute communications will begin when you switch from departure control to ARTCC (hereafter referred
to as center). The phrasing of your initial contact with center should be in one of the following three
When operating in a radar environment and no position reporting is required: [name] Center, [aircraft
identification] at/climbing to/descending to/passing [altitude] for [altitude].
When a position report is required: [name] Center, [aircraft identification], [position], [altitude].
When no position report is required, but youre not in radar contact: [name] Center, [aircraft
identification], estimating [reporting point] at [time] [altitude].
When operating in a non-radar environment, you will give position reports to center at designated
compulsory reporting points along your route of flight. The report is always preceded by a courtesy call
which includes [name] Center, [aircraft identification], [position]. If centers reply is [Roger], then no
further information is required or wanted from the pilot. If center states [Go Ahead], then the full position
report is given. The report includes the following information:
Position - (Next reporting point)
Position - (Name only of next succeeding reporting point)
When you are operating under an IFR clearance, you may not deviate from it unless you obtain an
amended clearance or unless safety of flight considerations prohibit compliance.
When you are cleared to climb or descend at pilots discretion, you may do so, leveling off at intermediate
altitudes if so desired, but you may not return to an altitude once you have vacated it.
Dont forget to report leaving altitude.
When cleared to a point short of your destination, you should ask for an expected further clearance (EFC)
time, if it is not given or offered. When cleared to a point not on your route of flight, you must receive
expected further routing (EFR). You should normally receive further clearance at least 5 minutes prior to
reaching your clearance limit.
Request an amendment to your clearance as early as possible to avoid delays. Refer to the format for
filing a flight plan while airborne and requesting a change of routing on the back of the FLIP IFR Enroute
Supplement or in the Flight Information Handbook.
