OMA 8.4 All Weather Ops Flashcards
Must all navaids be identified?
Yes.
How many approaches may be made?
Two at the same aerodrome due to weather, unless:
* significant improvement / emergency
* exceptional circumstances: 3rd may be flown if satisfied that landing assured
Minima for visual? Instrument to visual (straight in)?
Ceiling of 2,500 ft AAL
Visibility 5k (or circling minima)
RVR over 800m
this is same as max CMV
What is the approach ban?
Which RVR (s) is controlling?
Minimum RVRs for approach?
Applies to RVR / Vis only
May begin an approach, but shall not be continued past 1000 RA* or Final approach if DH above 1000 AAL
TDZ RVR is controlling for all instrument approaches
So are MID and END if reported and relevant.
Chart / 125 / 75
Chart / 75 / 75 if roll-out guidance
Cat IIIb NO DH- only 1 RVR needed
Which RVRs are relevant for take off and landing?
RVRs for all parts of runway used for TO roll with RTO to 60kt
Landing to 60kt
What is the definition of an NPA or APV?
Which approaches are NPA / APVs?
Non-precision approach / Approach with vertical guidance:
MDA/H 250 ft or more
RVR CMV 750 m or more
APV: RNP LNAV/VNAV and RNP AR
All others are NPA (inc. RNP with LNAV only minima)
What are the visual references for NPA/APV approaches?
- Elements of ALS
- Threshold / markings / lights (inc. flashing)
- PAPI
- TDZ / markings / lights
- Runway edge lights
- Other CAA accepted references
Must raw data be monitored if using an overlay?
Can VNAV be used with temperature corrections?
Yes, and database must be up-to-date.
VNAV cannot be used with temp corrections
RNP AR:
When can constraints be changed?
When can a Direct To be used?
What visual references?
Initial, Intermediate and Missed Approach segments
Direct To only before FAF and not to the start of an RF leg
Same visual references as NPA/APV
* Elements of ALS
* Threshold / markings / lights (inc. flashing)
* PAPI
* TDZ / markings / lights
* Runway edge lights
* Other CAA accepted references
Cat I approach (includes PAR)
Visual references?
LTS CAT I visual references?
Cat I Virtually same as NPA
LTS CAT I:
* 3 consecutive lights
* centre of ALS
* TDZ
* Centre / edge
* Combination thereof
* 1 lateral element
* ALS crossbar
* threshold / TDZ barrette
Circling- which pilot should be PF?
What changes made to stability criteria?
Visual references?
Allowed at night?
Can visual references be lost?
If no prescribed tracks, when can the commander leave the initial instrument approach track?
Pilot closest to runway
* Commander must consider FO experience *
400 TDZE- max bank 15º, within 30º of Final Approach Track
Can only begin descent below MDA once visual (and references maintained)
Runway environment
Not allowed at night without vertical guidance (PAPI, VASI, ILS)
May lose visual references ONLY with prescribed tracks AND visual with ground / obstacles
Can only leave instrument approach when commander estimates in all probability, continuous visual contact with runway will be maintained, remaining in circling area
Preparation for LVO approach?
Check notams for lighting, navaids, RVR sensors
Check QRH/FCOM for required equipment
Check both alternates if below CAT I minima
Consider extra fuel for approach delays
What conditions for a ‘successful’ autoland / approach?
50 RA to Flare
* Speed ± 5kt of bug (ignore fluctuations)
* No relevant system failure
300 ft to DA
* No excess deviation
* No go around command from FWC
Landing
* No relevant system failure
* No flare failure
* No de-crab failure
* Between 150-750m of threshold
* Not outside TDZ edge
* No excessive sink
* Bank angle within limit
* No roll-out failure/dev
When must CM1 perform LV take off?
How low RVR is aircraft certified for?
- CM1 when RVR below 400m (550m)
- Approved for less than 150m (to 125m)
Cat II minima and visual references?
100-200 ft
RVR 300 (350 for OTS)
Same visual references as LTS Cat I
