IFR Departure
AIM 5-2-9 – Departure Procedures
Ensures obstacle clearance, provided the airplane –
crosses the departure end of the runway at least 35' AGL
reaches 400' AGL before turning
climbs at least 200' per NM FPNM or as published otherwise on the chart
FPM = FPNM / 60 x Groundspeed
TPP climb/descent rate chart
Pilots are encouraged to file a DP at night, during marginal VMC or IMC
Departure Plates
Takeoff Minimums
FAR 91.175(f) – Clvil airport takeoff minimums
No takeoff minimums mandated for Part 91 operations
Equipment
Requirements
RADAR Departure Procedure
- ATC radar vectors to an ATS route, NAVAID, or fix are used after departure
- Annotated "RADAR REQUIRED"
RNAV Departure Procedure
- For aircraft equipped with RNAV equipment GPS, VOR/DME, DME/DME
- Require at least RNAV 1 performance
- Annotated "RNAV"
Non-RNAV Departure Procedure
- For use by aircraft equipped with ground-based navigation VOR, DME, NDB

SID Standard
Instrument Departure
- Reduces pilot and controller workload by simplifying ATC clearances and radio communications
Transition routes connect the end of the basic SID procedure to the enroute structure
- Must be cleared by ATC, pilots are not required to accept if assigned
Pilots may request “NO SIDs” in the flight plan’s remarks section
- Always printed graphically
- May depict special radio failure procedures
ODP Obstacle
Departure Procedure
- Provides only obstacle clearance
- Printed either textually or graphically
- No ATC clearance needed, pilots must ask to fly an ODP
- Used if obstacle exists on a 40:1 departure flight path
- Graphic ODPs are titled 'OBSTACLE'
DVA Diverse
Vector Area
- Diverse Airport Departures provide obstacle clearance when a DP is not published
- Initial radar vectors and climb gradients may be provided by ATC
- All US airports with a published IAP but with no published DP meet the Diverse Airport criteria
- This criteria requires that an airport has been evaluated for no obstacles within 200' altitude/NM up to a minimum IFR altitude
- Minimum Climb Gradient
VCOA Visual Climb
Over Airport
- A departure option for IFR aircraft in VMC
- The pilot visually conducts climbing turns over the airport up to the published "climb to" altitude, from which he proceeds to the instrument portion of the departure
- Designed to avoid obstacles beyond 3 SM from the departure end of the runway (DER), as an alternative to complying with climb gradients greater than the standard 200 ft/NM
- Advise ATC as early as possible prior to departure of the intent to fly a VCOA
- Published in the “Take-Of Minimums and (Obstacle) Departure Procedures” section of the TPP
- May appear as an option on graphic ODPs
