N5006 Flashcards
What are all the methods of departing IFR?
- Published ODP; textual or graphic, including Reduced Takeoff Runway Length (RTRL) and Visual Climb Over the Airport (VCOA) procedures.
- SID
- Specific ATC Departure Instructions.
- Diverse Departures (Omni-directional Departures-ICAO).
- Special MAJCOM Certification (authorized locations, pilots and aircraft only).
- Non-Standard Takeoff Minimums
AFI 11-202 Vol 3, 5.5
How do you apply Non-Standard Takeoff Minimums?
Departures using non-standard takeoff minimums (ceiling and visibility) must ensure the aircraft is at or above the published ceiling by the end of the runway (OEI for multi-engine fixed-wing aircraft), then continue climbing at 200’/NM (or IAW 5.4.3.1.2.1.) to a minimum IFR altitude (T-1).
AFI 11-202 Vol 3, 5.5.2.5
When executing a VCOA, how close must
you remain to the airfield?
Unless published, pilots will consider VCOA visibility requirement as the “remain within” distance and do not exceed this radius from the center of the airfield while climbing to the specified altitude.
AFI 11-202 Vol 3, 5.5.2.2.1
Can you fly a VCOA at night?
Pilots without NVDs will not fly a VCOA at night, unless specifically authorized by the MAJCOM. (AETC) Aircrews will not fly a VCOA at night.
AFI 11-202 Vol 3, 5.5.2.2.1
When flying a SID, what climb gradient is
required?
Follow SID procedures as published. Comply with applicable notes, low close-in obstacles, and climb gradients on the SID. SIDs without a published climb gradient have been assessed at 200 ft/NM. If the SID does not have published low close-in obstacles but has an ODP annotated, refer to the corresponding runway ODP for potential low close-in obstacles. Reference all published low close-in obstacle locations to ensure compliance.
AFI 11-202 Vol 3, 5.5.2.3
When given specific ATC Departure
Instructions, what must the pilot do in all
cases?
- If the departure runway has any published climb gradients, the PIC must meet or exceed the highest gradient when departing via ATC instructions.
- If unable to meet any ATC climb gradient, coordinate with ATC prior to flying the procedure.
- Pilots are never relieved of the responsibility for terrain and obstacle avoidance. The radio call “Radar Contact” only means the aircraft has been identified on radar. Responsibility is shared between pilot and controller only after navigational guidance is issued.
- Outside the NAS, use caution when flying radar vectors. See paragraph 8.13.2
AFI 11-202 Vol 3, 5.5.2.4
When is a diverse departure not
authorized?
Diverse departures are not authorized when an ODP, obstacle climb gradient, or non-standard takeoff weather minimums are published for the planned departure runway
AFI 11-202 Vol 3, 5.5.2.1
Regardless of the IFR departure method
selected, PICs will climb at what rate,
unless a higher gradient is published for the
departure runway (in a departure procedure
or Trouble T)?
200 ft/nm
AFI 11-202 Vol 3, 5.4.3.1.2
You see in the Trouble T section, “or
standard with minimum climb of 315’/nm
to 2000.” What does the “standard” refer
to?
Standard takeoff weather minimums. USAF pilots shall comply with takeoff weather minima IAW AFI 11-202V3 and AFI 11-2MDSV3. Pilots of USAF aircraft will not use FAA or civil takeoff weather minima nor fly “see and avoid” in lieu of IFR climb gradients unless specifically authorized by the MAJCOM/A3 or as provided by AFI 11-202V3.
AFMAN 11-217V1, 7.2.2
When flying a Departure Procedure,
aircrew must delay all turns until at
least_____ feet above the DER elevation,
unless__________.
400 , unless an early turn is specifically required by the departure procedure.
AFMAN 11-217V1, 7.2.3
What is considered the Runway End
Crossing Height for departures designed by
the USAF/USN? Other?
At non-joint-use USAF/USN bases, assume a 0 foot runway end crossing height unless a higher altitude is published. Everywhere else, if the screen height is not published in the ODP or other reliable source, pilots will plan to cross the DER at or above 35 feet.
AFMAN 11-217V1, 7.3.3.1.
You see in the Trouble T section the
following: “with standard takeoff
minimums and a normal 200’ per NM
climb gradient, takeoff must occur no later
than 1600’ prior to the departure end of the
runway.” Is this allowed?
Yes. USAF pilots shall only use an RTRL procedure if it is published as an ODP in FLIP. Pilots must check takeoff and landing data (TOLD) carefully when planning this type of departure. In the example below, subtract the value in the RTRL procedure from the usable runway length to determine the “reduced runway length”. Compare your aircraft’s “takeoff ground run” or “takeoff distance” value to the new reduced runway length. If the reduced length is equal to or greater than your aircraft’s calculated “ground run”, the procedure may be flown using a standard climb gradient of 200’/NM.
AFMAN 11-217V1, 7.4.1.3
What does it mean when you see a Trouble
T on an approach plate?
The presence of the ―Trouble T means IFR takeoff minima and departure procedures are prescribed for specific airports/runways. Typically, this means obstacles penetrate the 40:1 OCS.
AFMAN 11-217V1, 7.4.1.1
You read in the front of the IAP book “Diverse departures authorized 071 to 141 CW with minimum civil climb of 450’/NM to 6900, minimum military climb of 390’/ NM to 6300.” Can USAF aircraft execute this procedure?
Yes. Sector Diverse Departures are considered ODPs.
AFMAN 11-217V1, 7.4.2.
You see in the Trouble T section that a climb gradient in excess of 200 ft/nm is required for your intended runway. No other instructions are published. May you execute a Diverse Departure?
NO, technically you are flying an Obstacle Departure Procedure (ODP). By definition a diverse departure requires no more than 200 ft/nm climb gradient.
