• There is no precipitation or visible moisture
• Tank fuel temperature is at or above -16°C
Or if conditions are not met 3mm.
Upper wing:
• The CSFF on the wing tank upper surfaces is only within the
lines defining the permissible CSFF area with no ice or frost on
the leading edges or control surfaces
• Ambient air temperature is at or above +4°C
• There is no precipitation or visible moisture
• Tank fuel temperature is at or above -16°C,

Question 19

Minimum fuel at destination

Answer 19

1. The final reserve fuel plus the required alternate fuel (to the alternate requiring the higher fuel, if 2 destination alternates are required); or
2. The final reserve fuel plus fuel for 15 minutes holding at 1,500 ft above the destination airport elevation in standard conditions if a destination alternate airport is not required; or
3. The fuel required to operate to an isolated airport (fuel for 2 hrs at cruise speed above the destination airport).

Question 20

Diversion to Destination

Answer 20

1. An assured landing can be made in the immediate and prevailing operational conditions; and
2. An Expected Approach Time (EAT) has been allocated, or confirmation directly from ATC of the maximum likely delay

Answer 23

• A delay of more than 3 hrs;
• Aircraft (tail number);
• Type of dispatch – (between RCF, Normal or EDTO);

• Change in TOW of +3,000kg or -6,000kg for 787 aircraft;
• Change to High/Low airspeed dispatch;
• Change of Destination;
• In any other case if, in the opinion of the PIC or the FOO, a substantial change in the Flight Data has occurred.

Question 24

Landing RVR

Answer 24

The touchdown zone RVR is always controlling. If reported, the mid point RVR is also controlling, and if the stop end RVR is reported and relevant it is also controlling. The minimum RVR value for the mid-point is 125 m. The minimum RVR value for the stop-end is 75 m.
NOTE: “Relevant” in this context, means that part of the runway used during the high speed phase of the landing down to a speed of approximately 60 kts.

Question 25

A visual approach may be performed by:

Answer 25

• DayWhen the airport and surrounding terrain can be seen from a distance, or the airport becomes visible following an instrument approach procedure;•
NightWhen the airport becomes visible.
The runway environment shall be kept in sight while maneuvering visually.

Question 26

Visual Traffic Pattern

Answer 26

• Ceiling: 1,500 ft;

* Visibility: 3 statute miles/5 km.

Question 27

Circling approach

Answer 27

Circling approaches are to be carried out by the PIC.
The EL AL Circling minima are:
• MDA: 1,000 ft;
• Visibility: 5 km

Question 28

CAT II Approaches

Answer 28

Decision height not lower then 100ft.
A runway visual range not less than 300 m.

CAT II approaches and landing should be performed with the autopilot engaged (manual landing is allowed when a system malfunction predicates a manual landing).
NOTE: For CAT D aircraft an RVR of below 350 requires autoland.

Question 29

Category IIIA Approaches

Answer 29

Category IIIA (CAT III/A) operation is a precision instrument approach and landing with:
1. A decision height lower than 100 ft but not lower than 50 ft; and
2. A runway visual range not less than 200 m.
CAT IIIA operation is automatic to touchdown using automatic landing.

Question 30

BR

FG

Answer 30

1000-5000m

<1000m

Question 31

Alternate Fuel to include fuel for

Answer 31

a. A missed approach from the applicable MDA/DH at the destination airport to missed approach altitude; and
b. Climb from missed approach altitude to cruising level/altitude, taking into account the expected departure routing; and
c. Cruise from top of climb to top of descent, taking into account the expected routing; and
d. Descent from top of descent to the point where the approach is initiated, taking into account the expected arrival procedure; and
e. Executing an approach and landing at the destination alternate airport as filed in the OFP.
