Departure Flashcards
(42 cards)
What is the standard minimum required departure Climb Gradient?
AIM 5-2-9
200 ft per NM
What is the IFR departure clearance acronym we use?
CRAFT
C - Clearance Limit (cannot fly beyond this point unless given further clearance
R - Route
A - Altitudes
F - Frequency
T - Transponder code
What does ‘cleared as filed’ mean?
AIM 5-2-6
You are cleared to depart and fly your route exactly as proposed in the flight plan
What are the types of departure time restrictions ATC may place on you?
- Clearance Void Times
- Hold For Release
- Release Time
- Expect Departure Clearance Time (EDCT)
**Obtain IFR clearance before departure when able
What is an Expected Departure Clearance Time (EDCT)?
- Assigned to aircraft to manage traffic separation
- You are expected to departure no earlier than 5 mins before and no later than 5 mins after the EDCT
Not all airports participate in EDCTs
What is a Release Time?
Its the earliest time an aircraft could be released for departure
What is a Hold For Release?
You cannot take off until ATC specifically releases you
- ATC may ask you to report when holding short of the RWY so they can reevaluate your hold for release
What is a Clearance Void Time?
Your IFR clearance will be voided if you are not off the ground by a specified void time
- May be given when departing a Non-Towered airport
- You must notify ATC as soon as it becomes evident that you wont be off by your void time
How would you obtain your departure clearance if you were departing an airport IFR and you could not get radio reception for ATC or an FSS?
You must call ATC or FSS by phone.
- Numbers will be listed in the CS
What is a Diverse Vector Area (DVA)?
AIM 5-2-9
Areas in which ATC may provide random radar vectors during a climb out.
DVAs provide obstacle and terrain clearance in lieu of a SID or ODP, but only after the controller begins the radar vectors
- This is due to the minimum climb gradient being met in all directions up to MOCA/MEA
- The DVA will be listed on the 10-9 or in the TPP
- DVAs MAY require MORE than the standard 200ft per NM climb gradient and will be stated if so.
Where can you find Departure procedures?
AIM 5-2-9
They are listed by airport in the IFR Takeoff Minimums and ODP section (L) of the TPPs
Find them on the 10-9 page on Jepp charts
What does ‘climb via SID’ mean in a departure clearance?
AIM 5-1-9
This is a type of abbreviated clearance instructing you to comply with the SIDs altitude restrictions, lateral path, and speed restrictions. (unless otherwise stated)
*Departure SID will be given in clearance.
How do you determine if Takeoff Minimums are NOT standard?
A ‘T’ inside of a triangle will appear on the IAP notes section.
You will just have to check the mins always, for Jepp charts
**its important to check IAPs for the departure RWY before leaving
How do you determine if Departure Procedures are published for an airport?
A ‘T’ inside of a triangle will appear on the IAP notes section.
You will always have to check the 10-9 page for Jepp charts
**its important to check IAPs for the departure RWY before leaving
When departing, how can you determine if you will have adequate obstacle and terrain clearance?
AIM 5-2-9
- Check if an ODP is available
- Check the type of terrain and obstacles around
- Consider how high density altitude or an engine trouble would effect your climb performance
If an ODP is published for your departure RWY, are you required to follow it?
No
If a part 91 pilot is not given a clearance containing on ODP, SID, or radar vectors and an ODP exists compliance is not mandatory.
**its a good idea to fly the ODP anyways
What are the IFR Take Off Minimums?
Part 91 - NONE
Everyone else
- Prescribed T/O mins for specific RWY
- 1 or 2 engines = 1 SM Viz
- More than 2 engines = 1/2 SM viz
Describe what the different triangles in an IAPs note section mean
T = Non-Standard T/O or departure mins
A = Non-standard IFR alternate Mins
A NA = Alternate Minimums Not-Authorized
What 3 items make up the Standard IFR Departure Criteria?
AIM 5-2-9
- Crossing the departure end of RWY (DER) at least 35ft above elevation
- Climbing to 400ft above DER before any turn
- Min climb gradient of 200ft per NM or as specified
*and the aircraft is functioning normally
When planning for an IFR departure, how will you determine and convert your required climb gradient from ft per NM to FPM?
There are two options: the 2nd is preferred because it wont required interpolation.
- Use the chart found in the digital Terminal Procedures Supplement
- GS/60 x Required Gradient = FPM required
What is an ODP?
Obstacle Departure Procedure: A type of IFR departure procedure designed to provide obstacle/terrain clearance
- ATC clearance is NOT required to fly an ODP
- Printed Textually or Graphically
What is an IFR Departure Procedure (DP)?
A procedure designed to provide aircraft with obstruction/terrain clearance from the RWY to the enroute environment
Who is responsible for determining if an ODP should be flown?
The pilot in command should determine if an ODP should be flown, especially if not assigned by ATC instruction.
*its a good idea to fly an ODP anytime one is available under IFR.
What is a SID?
Standard Instrument Departure - A type of departure procedure that includes detailed graphical information guiding aircraft from the airport to the enroute environment with obstacle/terrain clearance
1. Requires ATC clearance
2. Primary goal is to reduce workload
3. Usually published at busier airports
4. Increases capacity of terminal areas
- there are 3 types: Radar Vector, RNAV, and Pilot Nav
