EDTO

Question 1

What year did ETOPS officially start?

Answer 1

1985

Question 2

When are EDTO rules active?

Answer 2

From brake release for the purpose of taking off

Question 3

What is the definition of when a flight becomes an EDTO flight?

Answer 3

When more than 60 min flying time, in still air, at normal OEI cruise speed from an adequate airport

Question 4

What is the max EDTO diversion time HKE is approved for?

Answer 4

120 min

Question 5

What power setting is used for the 120 min EDTO diversion time

Answer 5

MCT, as it is a OEI speed

Question 6

What is the EDTO OEI cruise speed used for A320/A321 in the approval?

Answer 6

A320-232: 418 kts
A321-231: 404 kts

Question 7

What is the approved EDTO maximum diversion distance for the A320/A321?

Answer 7

A320-232: 835 nm
A321-231: 780 nm

Question 8

Define “EDTO Adequate Airport”?

Answer 8

Sufficient:
LDA
ATC
Lighting
WX reporting
1 nav aid (no RNAV)
RFFS services min Cat 4

Question 9

Is EDTO operation allowed to Isolated Airports?

Answer 9

No

Question 10

Can Departure, Destination and Destination Airport(s) be used as EDTO En-route Alternate Airport(s)?

Answer 10

Yes

Question 11

What are the required planning minimas for enroute EDTO alternates?

Answer 11

* Single ILS*: 600ft or 400ft above the lowest authorized DH, whichever is highest and
3000m or 1500m above the lowest authorized VIS/RVR

* NPA/Circling: 800ft or 400ft above the lowest authorized MDH, whichever is highest and
3000m or 1500m above the lowest authorized VIS/RVR

• With 2 separate runways the cloud base can be reduced by 200ft and VIS/RVR can be reduced by 1000m

Question 12

What kind of weather forecasts indicators has to be considered for EDTO alternates?

Answer 12

FM, TEMPO and BECMG
PROB more than 40%

Question 13

For what period does an EDTO enroute airport has to be suitable in the planning phase?

Answer 13

ETA +- 1h

Question 14

What is the difference between an EDTO ETP and CP?

Answer 14

• ETP is a point on the route which is located at the same flying time from two suitable diversion airports
• CP is an ETP which is critical to EDTO fuel requirements if a diversion is initiated from that point
  CP is usually the last ETP within the EDTO segment

Question 15

Define Point of No Return (PNR)?

Answer 15

The last possible point at which an aircraft can proceed to the destination airport as well as to an available en-route alternate airport

Question 16

What fuel is required for an EDTO flight?

Answer 16

Normal HKE fuel policy plus that enough fuel needs to be carried to allow a diversion to nearest suitable EDTO ERA from any point along the route.

Fuel to diversion has to cater for:
- Engine failure only
- Engine failure +
depress
- Pressurization only
+15 min hold at 1500ft
+ additive for icing

Question 17

Is EDTO considered extra fuel or is it part of the required fuel on the HKE fuel planning schedule?

Answer 17

It is included in the Fuel Required

Question 18

Define the Critical Fuel Scenario (CFS) as it relates to EDTO planning?

Answer 18

Most critical of:
- Engine failure + pressurization failure
- Pressurization failure only

Question 19

How is the CFS calculated for EDTO planning?

Answer 19

• Burn off from CP to
  diversion AD
• 5% of diversion burn
• 15 min holding
• Two approaches
• Effect of MEL/CDL
• APU fuel consumption
• Icing, if forecasted

Question 20

Up until what point is the MEL applicable?

Answer 20

Up until the start of the takeoff roll

Question 21

After take-off on a EDTO flight, what minima apply once airborne?

Answer 21

Normal minima as per OM-C
