11-202V3 Flashcards
WX to File to Destination
Prevailing weather for the estimated time
of arrival (ETA) 1 hour at destination must be at or above the lowest compatible
published landing minimums (TEMPO conditions may be below published
minimums at ETA 1 hour)
Requiring an IFR Alternate
WWWRRANG
- Ceiling less than 2000 ft or a visibility of 3 SM
- 4.15.3.2.1. All compatible approaches require radar (T-1);
4.15.3.2.2. Required navigational aids (NAVAID) will be unmonitored (T-1);
4.15.3.2.3. The destination has no weather reporting capability (T-1);
4.15.3.2.4. The airfield’s lowest compatible approach weather minimums are greater
than or equal to a 1,500 ft. ceiling or 3 SM visibility (T-1); or,
4.15.3.2.5. GPS is the only available NAVAID (T-1).
4.15.3.2.6. (Added-AETC) Regardless of weather, where forecast winds exceed
aircraft limits ± 1 hour of ETA.
4.15.3.2.7. (Added-AETC) Regardless of weather, when denial of accommodation
to reduced vertical separation minimum (RVSM) airspace would prevent the aircraft
or flight from reaching its planned destination, a suitable alternate will be designated
that does not require accommodation.
- Destination with single compatible runway (80 OG)
Disqualfying Alternate
WWWRRANG
- A ceiling of 1000 ft., or 500 ft. above the lowest
compatible minimum, whichever is higher; and a visibility of 2 SM or 1 SM above
the lowest compatible minimum, whichever is higher
- Alternate without a Published or Compatible Instrument Approach
Procedure. Forecast weather for the ETA (±1 hour) must permit a VFR descent
from a published IFR altitude to a VFR approach and landing (T-0). Conditions in
para 4.15.3.5. do not apply when utilizing this option.
4.15.3.5.1. All compatible approaches require radar (T-1).
4.15.3.5.2. All compatible approaches require an unmonitored NAVAID (T-1).
4.15.3.5.3. The airfield does not have a weather reporting service (T-1).
4.15.3.5.4. “ ANA” (Alternate Not Authorized) on all compatible approaches (T-1).
4.15.3.5.5. Any note disqualifying the airfield or all compatible approaches in the
IFR Alternate Minimums section (T-1).
4.15.3.5.6. GPS is the only available NAVAID (T-1).
4.15.3.5.7. (Added-AETC) Regardless of weather, forecast winds exceed aircraft
limits ± 1 hour of ETA.
4.15.3.5.8. (Added-AETC) Regardless of weather, access to RVSM airspace is
required to reach the alternate for non-compliant aircraft.
Fuel Reserve
Fuel Reserve. Ensure the aircraft is carrying enough usable fuel on each flight to
increase the total planned flight time between refueling points by 10 percent (up to a
maximum of 45 minutes or 20 minutes, whichever is greater
For turbine-powered aircraft use fuel consumption rates that provide best
endurance at 10,000 ft. MSL (T-1).
Minimum Takeoff WX
Takeoffs are prohibited when existing weather is
below landing minimums (T-2). MAJCOMs will publish alternative takeoff minimums and
recovery procedures when takeoff weather is lower than published landing minimums. In all
cases, takeoff visibility must be 600 RVR (180 meters) or greater (T-1).
5.1.1.1. Fixed-wing RVR Requirements. Takeoff with weather below 1600 RVR is not
authorized unless the runway has operating centerline lights, visible runway centerline
markings, and two operative RVR reporting systems (T-1). All RVR readings must meet
or exceed minimum authorized values for departure (T-1).
5.1.1. (AETC) Minimum Takeoff Weather. Unless specifically addressed in AFI 11-2
MDS-specific guidance, aircrews will not take off when the weather is lower than the pilot
weather category minimums or published landing minimums, whichever are higher. When
AFI 11-2 MDS-specific guidance authorizes takeoffs with weather below landing minimums,
the guidance is only considered valid for AETC aircrews if it prescribes alternate takeoff
minima and substitute recovery procedures.
IFR Departure Methods
- 5.1.1. Diverse Departure (ICAO - Omnidirectional Departure).
- 5.1.2. Obstacle Departure Procedure (ODP). Climb gradient greater than 200’/NM is required to clear obstacles
- Routings
- Low Close-in Obstacles
- VCOA
- RTRL - 5.1.3. Standard Instrument Departure (SID).
- 5.1.4. Specific ATC Departure Instructions
- 5.1.5. Non-Standard Takeoff Minimums. When obstacles penetrate the 40:1 OCS, non-standard takeoff weather minima are provided for commercial civil pilots to “see-and-avoid” obstacles during departure. USAF cannot do see and avoid. May only use non-standard wx if performance OEI will allow aircraft to climb to the non-standard ceiling req by DER and comply with published climb gradients thereafter to a published IFR altitude
- 5.1.6. MAJCOM Certified Procedure..
TDZE
Highest point in the first 3,000 feet of the landing surface
Field Elevation
Highest point on any usable landing surface
TCH
Threshold Crossing Height - refers to the point where the descent angle crossses above the threshold. Unless required by larger type aircraft, the typical TCH will be 30-50 feet
Holding Times
Above 14k - 1.5 Minutes
At or below 14k - 1 Minute
Holding Airspeeds
MHA thru 6k - 200 KIAS Abv 6k thru 14k - 230 kias Abv 14k - 265 kias USAF - 310 KIAS max USN - 230 KIAS max
