FLIGHT PLANNING CONSIDERATIONS
Take into consideration the departure paths included
in the SIDs and determine if you can use a standardized
departure procedure. You have the opportunity to
choose the SID that best suits your flight plan. During
the flight planning phase, you can investigate each
departure and determine which procedure allows you
to depart the airport in the direction of your intended
flight. Also consider how a climb gradient to a specific
altitude will affect the climb time and fuel burn
portions of the flight plan. If ATC assigns you a SID,
you may need to quickly recalculate your performance
Another important consideration to make during your
flight planning is whether or not you are able to fly
your chosen departure procedure as charted. Notes giving
procedural requirements are listed on the graphic portion of a departure procedure, and they are mandatory
in nature. [Figure 2-25 on page 2-25] Mandatory
procedural notes may include:
- Aircraft equipment requirements (DME, ADF,
- ATC equipment in operation (RADAR).
- Minimum climb requirements.
- Restrictions for specific types of aircraft (TURBOJET
- Limited use to certain destinations.
There are numerous procedural notes requiring specific
compliance on your part. Carefully review the
charts for the SID you have selected to ensure you can
use the procedures. If you are unable to comply with a
specific requirement, you must not file the procedure
as part of your flight plan, and furthermore, you must
not accept the procedure if ATC assigns it. Cautionary
statements may also be included on the procedure to
notify you of specific activity, but these are strictly
advisory. [Figure 2-26 on page 2-26]
Responsibility for the safe execution of departure procedures
rests on the shoulders of both ATC and the
pilot. Without the interest and attention of both parties,
the IFR system cannot work in harmony, and achievement
of safety is impossible.
ATC, in all forms, is responsible for issuing clearances
appropriate to the operations being conducted, assigning
altitudes for IFR flight above the minimum IFR altitudes
for a specific area of controlled airspace, ensuring the
pilot has acknowledged the clearance or instructions,
and ensuring the correct read back of instructions.
Specifically related to departures,ATC is responsible for
specifying the direction of takeoff or initial heading
when necessary, obtaining pilot concurrence that the
procedure complies with local traffic patterns, terrain,
and obstruction clearance, and including departure
procedures as part of the ATC clearance when pilot
compliance for separation is necessary.
The pilot has a number of responsibilities when simply
operating in conjunction with ATC or when using
departure procedures under an IFR clearance:
- Acknowledge receipt and understanding of an ATC clearance.
- Read back any part of a clearance that contains “hold short” instructions.
- Request clarification of clearances.
- Request an amendment to a clearance if it is unacceptable from a safety perspective.
- Promptly comply with ATC requests. Advise ATC immediately if unable to comply with a clearance.
When planning for a departure, pilots should:
- Consider the type of terrain and other obstructions
in the vicinity of the airport.
- Determine if obstacle clearance can be maintained
visually, or if they need to make use of a departure
- Determine if an ODP or SID is available for the
- Determine what actions allow for a safe departure
out of an airport that does not have any type of
affiliated departure procedures.
By simply complying with departure procedures in their
entirety as published, obstacle clearance is guaranteed.
Depending on the type of departure used, responsibility
for terrain clearance and traffic separation may be shared
between pilots and controllers.
