Chapter 8 - Operating Procedures Flashcards
What is Minimum Sector Altitude (MSA)?
MSA represents the safe altitude around a navigation station or aerodrome reference point. If no other information is present, the radius is 25 NM.
In case of an RNAV approach, MSA may be replaced by a Terminal Arrival Altitude (TAA).
Provide 1000 ft obstacle clearance down to the intermediate approach segment.
What is Route MORA – Company Operational Flight Plans (OFPs)?
The MFAs depicted on OFPs are based upon Route MORA and provide 1000 ft clearance for terrain up to 5000 ft and 2000 ft clearance for terrain above 5000 ft, within 20 NM of the route segment centreline. The minimum MFA value depicted on OFPs is 2000 ft.
What is Minimum Grid Altitude (MGA)
MGA represents the lowest safe altitude which can be flown off-track. It is calculated by rounding up the elevation of the highest obstruction within the grid area to the next 100 ft and adding an increment of:
• 1000 ft for terrain or obstructions up to 6000 ft; and
• 2000 ft for terrain or obstructions above 6000 ft.
The lowest indicated MGA is 2000 ft. This
value is also provided for terrain and obstacles that would result in an MGA below 2000 ft. An exception is over water areas where the MGA can be omitted.
When should Temperature corrections be applied? (Low Altitude)
Temperature corrections should be applied when the surface temperature is -10°C or below. Unless otherwise specified, the elevation of the aerodrome in use is taken as the elevation of the altimeter source. These corrections must be applied when conducting an instrument approach:
- To DA (except Baro-VNAV procedures that are published with a temperature limit) and MDA.
- Non-precision approach to minimum altitudes after passing the Final Approach Fix.
When should a Pressure Correction be applied?
When flying at levels with the altimeter set to 1013 hPa, the MFA must be corrected for deviations in pressure when the pressure is lower than the standard atmosphere (1013 hPa). An appropriate correction is 30 ft per hPa below 1013hPa.
What is the required Rescue and Fire Fighting Service (RFFS) for the 319/320?
6
What are the acceptable Downgrades of RFFS for Planning Purposes for Departure/Destination Airports?
RFFS Cat 6 is normally required.
RFFS Cat 5 may be permitted for certain aerodromes which experience low volumes of commercial air transport traffic. This will be indicated on the OFP when permitted.
What are the acceptable Downgrades of RFFS for Planning Purposes for Departure and Destination in
case of temporary downgrade notified by ATC, NOTAM, ATIS etc. for a period of time
not exceeding 72 hours?
Downgrade to RFFS Category 4 is permitted.
What are the acceptable Downgrades of RFFS for Planning Purposes for Take-off alternate, Destination alternate and Enroute alternate?
Non UK Aerodromes – RFFS 4.
UK Aerodromes – RFFS 5.
What is the definition of an isolated aerodrome?
An isolated aerodrome is one for which the alternate and final fuel reserve required to the nearest adequate destination alternate aerodrome is more than fuel to fly for 2 hours at normal cruise consumption above the destination aerodrome, including final reserve fuel.
(easyJet does NOT hold a specific approval to operate to an isolated aerodrome.)
When is a take-off alternate required?
When performance or meteorological conditions preclude a return to the departure aerodrome.
What is required of the Take off alternate?
To be located within one hour still air flight time at the one engine inoperative cruising speed (maximum continuous thrust speed) in ISA conditions based on the actual take-off weight.
The maximum distance allowed for this purpose is stated in OMB for the aeroplane type; this assumes maximum take-off weight.
When are two destination alternates are required?
- The weather reports or forecasts at destination are below the applicable planning minima.
- No meteorological information is available.
• The landing performance requirements cannot be assured at a destination aerodrome due to dependence on a specific wind component or runway
state.
What is the minima required for the Destination?
Shall be at or above the applicable minima for the expected instrument approach.
What is the minima required for the Destination Alternate and ERA Aerodromes at the planning Stage?
Cat II & Cat III = Cat I minima (RVR)
LTS Cat I = Cat I minima (RVR)
Cat I = NPA minima (RVR/ceiling above MDH)
Non-precision = NPA minima plus 200 ft/1000 m (MDH/MDA + 200 ft/RVR + 1000 m)
Circling = Circling minima
At least one usable destination alternate aerodrome must be selected for each IFR flight unless what?
• Dispatched under the Alternative Flight Planning Procedures in Section 8.1.7.6.5, “No Destination Alternate Aerodrome Procedure”.
• The duration of the planned flight from take-off to landing, or, in the event of in-flight re-planning, the remaining flying time to destination does not exceed
six hours.
• Two separate runways are available and usable at the destination and the appropriate weather reports or forecasts for the destination aerodrome indicate that for the period from one hour before until one hour after the expected time of arrival (ETA) at the destination, the ceiling will be at least 2,000 ft or circling height +500 ft, whichever is greater, and the visibility will be at least 5 km.
Or the destination aerodrome is isolated.
When are runways deemed separate?
Runways on the same aerodrome are considered to be separate runways when they are separate landing surfaces which may overlay or cross such that if one of the runways is blocked, it will not prevent the planned type of operations on the other runway. Each runway shall have a separate approach procedure based on a separate navigation aid.
What is a Category A Aerodrome?
Category A – Non-complex and can be treated as routine.
What is a Category B Aerodrome?
Category B – Complexity requiring specific briefing, e.g. audio visual briefing.
What is a Category B Restricted Aerodrome?
Category B Restricted – Complexity and threat levels requiring specified restrictions but not requiring an aerodrome visit or specific training.
What is a Category C Aerodrome?
Category C – Special crew qualification required which can be achieved by an aerodrome visit or specific training.
What is easyJet aeroplanes category?
Nominal indicated airspeed at the threshold (Vat) in the landing configuration.
A319, A320
Category C
From 121 to 140 kts

When can you NOT use a conversion from meteorological visibility to RVR/CMV?
- When reported RVR is available;
- For calculating take-off minima; and
- For any RVR minima less than 800m (after conversion).
Note: If the RVR is reported as being above the max value assessed by the aerodrome operator, e.g. “RVR more than 1500 metres”, it is not considered to be a reported value for the purpose of this paragraph. - When converting met vis to RVR in all other circumstances than those in (1) above, crew must use Table 8.7 Conversion of Met vis to RVR/CMV.
In flight, when can the met visibility be converted to RVR/CMV?
If RVR is not reported.
What is the Conversion of Met visibility to RVR/CMV for airports with HI approach and runway lighting? Day and Night?
Day = met vis x 1.5 Night = met vis x 2
What is the Conversion of Met visibility to RVR/CMV for airports with any type of lighting installation other
than HI approach and runway lighting? Day and Night?
Day = met vis x 1.0 Night = met vis x 1.5
What is the Conversion of Met visibility to RVR/CMV for airports with no lighting? Day and Night?
Day = met vis x 1.0 Night = Not allowed.
What are the requirements for a visual approach?
- A minimum of 2500 ft cloud base or circling minimum if higher;
