In general:
Alternates:
- 6 factors to consider before picking an IFR alternate.
- Alternate fuel planning for IFR. (Vid 23).
- Can you file to an 'alternate not authorized' airport? (Vid 58).
- IFR alternate (weather) requirements. (Vid22 or Vid 83).
- Does alternate need a published approach? Why or why not? Based on forecast.
- What are the approach requirements for an alternate?\
- What are the forecast requirements for alternate airport? At ETA must be:
- 600' ceiling w/ 2 SM visibility (airports w/ precision approach)
- 800' ceiling w/ 2 SM visibility (airports w/ non-precision approach)
- When do you need an alternate?
- When WX at destination airport +/- 1 hour of ETA is forecast to be less than 2000’ ceiling and visibility is forecast to be less than 3 miles (123 rule)
- What constitutes a ceiling? The lowest broken, overcast, or obscuration (not thin or partial) cloud layer
- Where do you find the non-standard alternate minimums? (checkride).
Altitudes, minimum (IFR) +
- 10 minimum IFR altitudes you should know.
- MAA – max authorized alt, marked
with “MAA-“
- MCA – min crossing alt, min al at
which to cross when proceeding to higher segment, marked with an “X” flag
- 150 FPNM (0-5K’ MSL); 120 FPNM (5K-10K’ MSL); 100 FPNM (10K’ MSL or above)
- MEA – min enroute alt, NAVAID
reception & obstacle clearance (top number on route)
- Also see "Enroute / Climb / Descent" below.
- If MEA and MOCA exists, you can use MEA but not below MOCA.
- What is MEA and MOCA and the difference? (checkride)
- MEA (RNAV) – same but annotated
with “G”, just below MEA
- MIA – min IFR alt, unless prescribed, 1K (non-mountain ) & 2k (mountain) clearance.
- MRA – min reception altitude,
marked with “R” flag
- MOCA – min obstruction clearance
alt, lowest to meet obstacle clearance and reception only to 22nm of VOR. Marked with *
- MSA – min sector alt, min 1K
obstacle clearance usually w/in 25nm
- MTA – min turn alt, provides
obstacle clearance for both turn after and turn anticipation, marked with “MTA”. (Vid 30).
- MVA – min vectoring alt, for
radar, the 1K & 2K clearance, can be lower than other alts (sometimes MRVA
– min radar vector alt or ASMA – ATC surveillance min alt)
- OROCA – off route obstruction
clearance alt, 1K obstacle clearance in non-mountainous and 2K in
mountainous. No signal guarantee. The large numbers in grids. (sometimes MORA –
min off route alt or Grid MORA)
- Minimum altitudes you may use for IFR Operations: (checkride)
- Except when necessary for takeoff / landing, minimum altitudes are:
- 2K’ above nearest obstacle w/in 4 NM of course (mountainous)
- 1K’ above nearest obstacle w/in 4 NM of course (non-mountainous)
- See also, Airspace and Altitude.

- Minimums:
- Minimums, descending below :
- Can you use the approach lights to descend on a non-precision approach?
- Position to land, required visibility, runway environment (12).
- Runway (itself, markings, lights) = 3
- Threshold (itself, markings, lights) = 3
- Touchdown zone (itself, markings, lights) = 3
- Visual approach slope indicator
- Runway end identifier lights
- Red terminating bars or red side row bars (see below)
- The approach lights - allow you to descend to 100 feet above touchdown zone elevation (to find another reference) OR below 100 feet if the red terminating bars or the red side row bars are also distinctly visible and identifiable.
- To descent below mins and/or land, you need to see at least one of these...
- Missed approach and Missed approach point (MAP):
- PAR (Precision Approach Radar):
- Plates (see charts / plates above)
- RNAV (GPS) Approaches:
- Difference between LPV and LNAV/VNAV.
- Explanations by: FAA.
- Remember, even with vertical guidance, and while using a DA (decision altitude), these are NOT considered precision approaches. They are APVs (APproaches with Vertical guidance). If you remember "guidance"/"glidepath" vs "glideslope", it will help separate these from precision approaches. RNAVs give glidepaths, while an ILS gives glideslope.
- LNAV - Lateral Navigation (uses an MDA)
- LNAV +V
- Only shows on your GPS (if able), not on plates. The vertical glide path is advisory only…you still need to fly step-down altitudes and MDA.
- Why won't +V clear stepdowns in the summer? (Vid 25).
- Will +V guidance clear stepdown restrictions? (Vid 16)
- LNAV/VNAV - Lateral Navigation/Vertical Navigation (uses a DA)
- First GPS approaches with vertical guidance – designed for BARO-aided GPS.
- Do not have increasing angular guidance as you approach the runway. They decrease to 0.3 nm sensitivity when w/in 2nm of FAF – all the way to MAP.
- The lowest they can go is 250’ above touchdown, but due to obstacles it’s often higher
- LP - Localizer Performance w/o Vertical Guidance (uses an MDA)
- LPV - Localizer Performance w/ Vertical Guidance (uses a DA)
- Uses WAAS/GPS, but NOT precision. They are APV (approach with vertical guidance). BARO-aided GPS doesn’t suffice.
- They are more sensitive as you get closer and are about 700’ at the threshold (like an ILS), but they essentially turn linear after the threshold
- Can’t use precision alternate minimums. You need WX that meets LNAV, circling or LNAV/VNAV DA
- Minimums - see above.
- RNAV and GPS: What's the difference?
- RNP, written "RNAV (RNP)", see below.
- Loading one in G1000 (see Equipment).
- Quizzes:
- See also vertical guidance below.
- RNAV RNP approach (FAA page)
- RNAV (GPS) vs. RNAV (RNP). (Vid 129).
- When you see RNP in the approach label, it can be interpreted as 'authorization required' because in reality, any RNAV has some RNP.
- Why do RNAV (GPS) approaches say 'RNP' in the top-left? (Vid 14).
- RVR
- You must use 2400 RVR when RVR is
not begin reported
- 2400 = 1/2 SM visibility
- Segments:
- Fly visual segment - what is it? (Vid 35 or Vid 98).
- Initial Approach Segment:
- This begins at the initial approach fix and ends where it joins the intermediate approach segment.
- Intermediate Approach Segment?
- This segment (normally aligned within 30 degrees of the runway) begins at the intermediate point and ends at the beginning of the final approach course.
- Final Approach Segment:
- For a precision approach, this begins where the glide slope is intercepted at the minimum glide slope intercept altitude shown on the approach chart;
- For a non-precision approach, this begins at either a designated Final Approach Fix (FAF) or at the point where you are established on the final approach course.
- Final Approach Fix vs. Final Approach Point. (Vid 115).
- When the FAF is not designated, such as where there is a VOR or NDB on the field of intended landing as published, the Final Approach Point (FAP) is where the procedure turn intersects the final approach course inbound.
- 5 ways to join final on an instrument approach.
- Should you ask to be 'cleared straight in'? (vid 44).

- The missed approach segment begins at the MAP and ends at a designated point.

- * unless specified different (crossing alt, DP) turn @ higher altitude or @ fix
- Departure clearance from a Class C airport. (Vid 19).
- DPs and ODPs (ODPs are normally narrative)
- Obstacles w/in 1nm & < 200’ tall are “low close-in obstacles” and are generally NOT factored in ODP
- IFR departure from a towered airport.
- Minimum takeoff WX? There isn’t, but a technique is highest published circling mins.
