Departure Procedures Flashcards
What is the OIS Line & How does it work?
-Obstacle Identification Surface Line
-Line is sent out at 152ft/nm. If nothing hits it, a safe IFR departure is possible
What are the standard requirements for an IFR Departure?
- Min climb gradient of 200ft/nm
- Reach 35ft by the departure end of the runway
- Make no turns until 400ft AGL
What if something hits the OIS Line?
-A nonstandard departure is required
-Symbolized by a T (usually on Approach chart)
What is feet per nautical mile?
Describes the amount of distance required to achieve an altitude
What is a Diverse Vectoring Area
ATC can vector you at lower-than-normal altitudes
What is a VCOA?
-Visual Climb Over the Airport
-Used as an alternative when non-standardized departure is required
-Requires clearance from ATC
What is an ODP?
-Obstacle Departure Procedures
-Pilot Requested
-Provides only obstacle clearance.
-Printed either textually or graphically.
-Graphic ODPs are titled “(OBSTACLE).”
What is a SID?
-Standard Instrument Departure
-Published routes with airspeed and routes.
What are the SID requirements?
-Must receive a clearance to fly a SID
-SIDS may be given when receiving an instrument clearance
-Pilot must obey the SID
-Must possess charted sid
What are the types of SIDs?
-Radar (Vectors)
-Hybrid (Some published routes & Vectors)
-RNav (All published)
What type of SID is this?
RNAV
What type of SID is this?
Vectors
What type of SID is this?
Hybrid
Why are SIDs used?
-To lessen ATC and Pilot workload
What do you need to do if you do not want to fly a SID?
Write it in the IFR File notes
Climb via vs Climb maintain, join
-Climb via: Follow the SIDs posted routes
-Climb maintain: Maintain a given altitude
Join: Join the route at a certain point (maintain already given altitude)
Bolded line vs skinny line
Bolded line: Published Route
Skinny Line: Transitions/Feeders
