Planning /OMA 8 Flashcards
What is the required RVR/vis and MDH for a NPA?
750m RVR
250ft MDH
What is the planning minima for a LTS Cat 1 approach?
Cat 1 approach, 550m
How long is the daily inspection valid for?
From 0001 of today until 2359 tomorrow with the check done after 1800 of yesterday
What is the applicability of weather planning minima for the selection of aerodromes?
Departure and take off alternate
= current weather
Destination and and destination alternate
= an hour either side of ETA, weather required for expected approach type
For NPAs and circling must consider ceiling height as well (BKN or OVC)
When can you/can’t you go through the approach ban?
Can - when RVR is above minima
Can’t - when RVR is below minima
If RVR goes below minima when you’re past the approach ban you can continue to MDH
What is the required weather for a circling approach?
RVR - can see the runway including threshold and approach lights
Cloud base must be above MDH
What is the minima for a visual approach?
5000m visibility
2500ft ceiling (BKN or OVC) or circling minima if higher
What are icing conditions?
OAT/TAT 10 degrees or less and visible moisture present
On the ground 10 degrees or less where snow, standing water or slush may be ingested
Within an hour either side of ETA, which weather time periods would you take into account?
Anything other than PROB TEMPO.
Eg FM, BECMG
You would take Prob 30/40 or TEMPO into account IF the weather is persistent weather eg FG, HZ etc
NOT if it is transient weather like showers
Gusts are disregarded
What is the take off planning minima?
Reported RVR is at or greater than the take off RVR required, see AOI
(above 125m RVR minimum)
Weather at departure aerodrome is good enough for a return OR a take off alternate is selected.
If met vis is below the minima you can use actual RVR if determined to be greater.
What is the planning minima for a NPA approach? (Inc LOC only)
NPA RVR + 1000m
Ceiling at or above MDH +200ft
What is the only autoland category to use a DA?
LTS Cat 1
What is the planning minima for a Cat 2 or 3 approach?
Cat 1 minima
550m RVR
What is the planning minima for a OTS Cat 2 approach?
Cat 1 minima
550m RVR
What is the planning minima for a Cat 1 approach?
NPA RVR
Ceiling at or above MDH
What is a contaminated runway?
25% of the total length of the runway is covered by greater than 3mm of water or a snow/slush/ice equivalent.
Or snow compressed into a solid weight, or any kind of ice.
Which MFA do you use for:
- Departure and climb
- En route
- Descent and arrival
- MSA on SID, under radar control the MRC chart altitudes.
- MORA
- Route MORA prior to establishment in published STAR and then MSA
What is OCA/H?
Minimum altitude/height above elevation used to comply with obstacle clearance criteria for a runway or aerodrome.
What is the missed approach point /MAP?
The latest point on an instrument approach at which the prescribed go around must be initiated in order to ensure minimum obstacle clearance.
What is MDA?
Minimum altitude on a non precision approach at which a go around must be initiated if you are not visual.
/below which descent is prohibited without the correct visual reference
What is DA/DH?
The minimum altitude/height on a precision approach below which descent is prohibited with the correct visual reference/at which missed approach must be initiated.
DA - reference to QNH
DH - reference to rad alt
What is the planning minima for an APV approach? (a NPA with vertical guidance)
NPA minima
750m RVR
250ft MDA
What is the planning minima for a circling approach?
Circling minima
RVR = can see the runway Cloudbase = above MDA
When CAN’T you convert met vis into RVR? (4)
- When the converted RVR is less than 800m
- At the planning stage
- When RVR is available
- When calculating take off minima
When would you carry out a security search? (6)
- When the previous sector departed from a non-EU country.
- When departing from the UK
- Cold aircraft
- Aircraft left outside for maintenance.
- Aircraft from a non-critical area
- Anytime you deem it necessary/safety has been compromised
What must pilots check on the outside of the aircraft?
Hatches, panels and cargo holds accessible from ground level.
Cargo holds only on non-revenue flights
What is the difference between height and altitude?
Height is referenced to radio altimeter/height from a specified datum.
Altitude is reference to mean sea level
When do you need a take off alternate?
What makes a suitable take off alternate?
When the weather OR performance at departure preclude a return.
A suitable take off alternate
- current weather above minima for expected approach type
- 1 hour flight time at OEI cruise speed at actual TOW
- maximum 320nm away
When do you need two destination alternates? (3)
- When weather isn’t available
- When landing performance is dependent upon weather, wind or runway state.
- When the forecast weather is below the applicable planning minima at destination.
What is the max distance from an adequate aerodrome? (no ETOPS)
60 minutes at OEI cruise speed
A319 = 380nm
A320 = 400nm
What is a suitable aerodrome?
Planning minima is met
Approach runway and aircraft capabilities associated with the met conditions are met
What is the allowed RFFS category for our aircraft?
6
7 A321
What is the allowed RFFS category after a downgrade for departure with low traffic?
