Question 1

Obstacle Departure Procedures (ODP) (AIM 5-2-8)

6 things

Answer 1

• Only provides obstruction clearance
• May be flown without an ATC clearance unless a SID or other instructions are assigned. (e.g. radar vectors)
• Graphic ODP denote “Obstacle” in the chart title.
• All new RNAV ODP’s are available in graphical form.
• Found in the front of NACO chart booklets, arranged alphabetically by city name.
• Jeppesen charts show ODP’s under the airport diagram (x0-9) page, or, at larger airports, on a separate chart.

Question 2

Standard Instrument Departures (SID) (AIM 5-2-8)

6 things

Answer 2

• Provide obstruction clearance and helps reducing radio congestion and workload by simplifying ATC clearances.
• Pilot NAV SID’s: Pilot navigates by charted routes with minimal radio instructions.
• Vector SID’s: Navigation is based on radar vectors. Routes are not printed on the chart.
• Some SID’s depict non-standard radio failure procedures.
• File “NO SID’s” in the remarks of your flight plan if you choose not to use them.
• RNAV SID’s and all graphical RNAV ODP’s require RNAV 1 performance. (+-1NM for 95% of the total flight time).

Question 3

Standard Terminal Arrivals (STAR) (AIM 5-4-1)

5 things

Answer 3

• Serves as a transition from the en route structure to a point from which an approach can begin.
• Transitions routes connect en route fixes to the basic STAR procedure.
• Usually named accrding to the fix at which the basic procedure begins.
• As with SID’s, you may state “No STARs” in your flight plan remark section if you choose not to use them.
• RNAV STARS require RNAV 1 performance.
