N5004 Flashcards
When must we fly IFR?
: Fly USAF fixed-wing aircraft under IFR to the maximum extent practical.
Pilots shall fly under IFR if:
- Weather conditions do not permit VFR flight
- Airspace rules require IFR flight (e.g. Class A airspace).
- Operating in excess of 180 KTAS within (not simply crossing) federal airways.
- Operating fixed-wing aircraft at night, unless the mission cannot be flown under IFR.
AFI 11-202 Vol 3, 4.15.1
What weather is required to file to a destination? How can you file IFR to an airport without a published instrument approach?
A: Prevailing weather for the ETA +/-1 hour at destination must be at or above the lowest compatible published landing minimums (TEMPO conditions may be below published mins).
If there is no compatible published approach at the destination, pilots may proceed to a point served by a published approach or to an IFR point where forecast weather at ETA +/-1 hour allows the pilot to continue VFR to the destination.
AFI 11-202 Vol 3, 4.15.2, 4.15.2.2
What weather at the destination requires an alternate?
: An alternate is required when the worst weather at destination, to include TEMPO conditions, ETA +1 hour is less than a ceiling of 2,000 ft and visibility of 3 SM.
AFI 11-202 Vol 3, 4.15.3.1
Are there exceptions to when weather at a destination requires an alternate?
AETC Waiver Vol 3/2000-2;
No alternate required if:
-Dep and Dest airports are same
-IP is a crewmember
-Wx reported and forecasted at or above 1,500 ft ceiling and 3 SM vis for planned mission’s duration or estimated time enroute plus two hours
-Flights limited to local training areas
-only applicable to AETC fixed wing training ops at: Vance AFB, OK and others
What additional conditions require an alternate?
-All compatible approaches require radar.
-Required NAVAIDs will be unmonitored
-Destination has no wx reporting capability
-Airfield’s lowest compatible approach mins are greater than or equal to 1,500 ft ceiling and 3 SM vis
-GPS is the only available NAVAID
-(AETC) forecast winds exceed a/c limits +- 1 hour of ETA
-(AETC) When denial of RVSM airspace would prevent a/c from reaching planned destination.
AFI 11-202 Vol 3, 4.15.3.2
AFI 11-202 Vol 3 AETC Sup, 4.15.3.2.5, 4.15.3.2.6
What weather is required when selecting an
alternate?
Worst forecast wx for ETA +1 hour, to include TEMPO conditions (except those caused by T-storms, rain, or snow showers), will meet or exceed:
-Ceiling of 1,000 ft or 500 ft. above the lowest compatible minimum, whichever is higher
-Visibility of 2 SM or 1 SM above lowest compatible published minimum, whichever is higher.
AFI 11-202 Vol 3, 4.15.3.4.1
What conditions disqualify an alternate?
- All compatible approaches require radar.
- All compatible approaches require an unmonitored NAVAID.
- Airfield does not have a weather reporting service.
-“A NA” (Alternate Not Authorized) on all compatible approaches. - Any note disqualifying the airfield or all compatible approaches in the IFR Alternate Minimums section.
- GPS is the only available NAVAID
-(AETC) Access to RVSM airspace is required to reach the alternate for non-compliant aircraft.
AFI 11-202 Vol 3, 4.15.3.5
AETC 11-202 Vol 3 AETC Sup, 4.15.3.5.8
What weather minimums are required for circling approaches?
Both the required ceiling and visibility minimums.
AFI 11-202 Vol 3, 7.1.2.2
When are cold weather altitude
corrections required?
- Below 0C: All altitudes inside the FAF or below 1000’ AGL.
- Below -30C: All altitudes on IAP.
- In mountainous terrain and below 0C: All altitudes on IAP
- If altitude on IAP is >3000’ above altimeter setting source and below 0C: All altitudes on IAP
AFI 11-202 Vol 3, Table 7.2
Advise ATC if any cold weather correction applied exceeds ____ft?
80
AFI 11-202 Vol 3, 7.2
What climb gradient is required on a
missed approach?
when starting the approach (AEO or OEI), ensure the aircraft can meet 200 ft/NM or the published missed approach climb gradient, whichever is higher, to an appropriate IFR altitude.
AFI 11-202 Vol 3, 7.8.2.2
When the runway approach lighting system is INOP, increase the published visibility minimums of an instrument approach by:
-As directed by the “INOP COMPONENTS” table in the TPP (front of approach book)
-As stated on IAP, NOTAMS, ATIS or other airport info source
-If no other guidance is provided, increase published visibility by 1/2 mile.
A: AFI 11-202 Vol 3, 7.6.3
May USAF fixed wing pilots accept a
LAHSO clearance?
No. Pilots of USAF aircraft may passively participate in LAHSO (land or take-off when another aircraft has been given a LAHSO clearance). The PIC is the final authority whether to take-off, land or continue a touch-and-go when a merging aircraft has received a LAHSO clearance.
AFI 11-202 Vol 3, 7.9.
When must the “gear down” call be
made?
Retractable gear aircraft will report gear down status to ATC or runway supervisory unit after extending the landing gear. This report shall be made during any approach to an airport prior to crossing the runway threshold.
AFI 11-202 Vol 3, 7.7
What is the minimum altitude
over congested areas (e.g. cities towns, settlements)?
At least 1,000 ft. above the highest obstacle within a 2,000-ft. radius of the aircraft.
