Departure: Departure Procedures Flashcards
What minimums are necessary for IFR takeoff under 14CFR Part 91? under 121, 125,129 or 135? (91.175)
Part 91: None
Parts 121,125,129,135: If takeoff minimum are not prescribed for a particular air port the following minimums apply for IFR takeoffs
•Aircraft with 2 engines or less: 1sm vis.
•Aircraft with more than 2 engines: 1/2sm vis.
What is considered ‘good operating practice’ in determining takeoff minimums for IFR flight?
If an IAP has been prescribed for that airport, use the minimums for that approach for takeoff.
If no IAP is available basic VFR minimums are recommended (1,000 and 3 miles)
What are DP’s and why are they necessary?
AIM 5-2-8
Departure procedures are pre-planned IFR procedures that allow obstacle clearance from the terminal area to the proper en-route structures.
Primary reason they’re established is for obstacle clearance.
Other reason is efficiency and reduce unnecessary communication and congested and busy airports.
What are the two types of DPs?
AIM 5-2-8
ODP (Obstacle Departure Procedures):
Printed in text or graphically, providing obstruction clearance via the least onerous route from the terminal area to the proper en route structure. Can be flown without ATC clearance if other clearance has not been given.
SID (Standard Instrument Departures):
ATC procedures always printed graphically, to provide obstruction clearance and transition from the terminal area to the proper en-route structure. Designed for system enhancement and to reduce pilot/controller workload. ATC clearance must be received prior to flying a SID.
What are the two types of SIDS?
What is a Pilot-navigation SID?
What is a Vector SID?
Pilot-navigation SID: designed to allow you to provide your own navigation with minimal radio communication . Usually contains an initial set of departure instructions followed by one or more transition routes.
Vector SID: Usually require ATC to provide radar vectors from just after takeoff (ROC is baed on a climb to 400 ft. above the DER elevation before making the initial term) until reaching assigned route or a fix depicted on the SID chart.
What criteria are used to provide obstruction clearance during departure (AIM 5-2-8)
Unless otherwise specified otehrwise:
Where are DPs located?
DPs will be listed in the IFR takeoff minimums and (obstacle) departure procedures section, Section L, of the Terminal Procedures Publications (TPPs)
Do you have to accept a SID if assigned one?
If you cannot comply with a SID, don’t posses charts or textual descriptions, or simply don’t want t use SIDs, include the statement “NO SIDs” in the remarks section of your flight plan.
How to determine rate of climb?
Ground Speed divided by 60 (minutes) times climb gradient =FPM
GS/60xClimb = FPM
How does a pilot determine if takeoff minimums are not standard and/or departure procedures are published at an airport?
If an airport has non-standard takeoff minimums a “triangle T” symbol will be placed in the notes section of the instrument procedure chart.
Prior to departing an airport on an IFR flight, a pilot should determine whether they will be able to ensure adequate separation from terrain and obstacles.
What information should this include? (4)
- Type of terrain and other obstacles on or in the vicinity of the departure airport
- Whether an ODP is available
- If obstacle avoidance can be maintained visually or if the ODP should be flown.
- The effect of degraded climb performance and the actions to take in the event of an engine loss during the plane.
If an ODP has been published for the runway you are departing from, are you required to follow it?
No; if they are not issued by ATC, textual ODPs are the pilot’s option to fly or not to fly, even in less-than-VFR weather conditions for part 91 operators.
When a DP specifies a climb gradient in excess of 200 feet per nautical mile, what significance should this have on the pilot?

What is the recommended climb rate procedure, when issued a climb to an assigned altitude by ATC?
IN BOOK
All public RNAV SIDs and graphic ODPs are RNAV1.
What does this mean?
