ETOPS 2 Flashcards
What is the vertical rule for weather deviation?
SAND
south ascend north descend
What should the height deviation be on a weather avoid?
- Nil within 5nm
- 300 ft if greater
For an inflight contingency, what should the change of heading be?
At least 30°
AC with an emergency should descend below what FL if no clearance from ATC?
FL290
For an in-flight contingency without clearance, what lateral separation is required?
5nm
If no clearance received from ATC below FL290, what vertical offset is required?
500 ft
How is the course entered in the RAD NAV page for a back course ILS?
B then enter the course

- M0.82
What is the standard strategy driftdown speed?
M0.82/300
What are the three ETOPS scenarios?
- Pressurisation and Eng Fail
- Pressurisation
- Eng Fail
What does ETOPS fuel allow for after a diversion from CP to ERA?
Fuel for Descent and Cruise
15 mins holding
Inst App
What are the EASA ETOPS minima for cloud ceiling for 2D and 3D apps?
3D: DH/DA + 200ft
2D: MDH/MDA + 400ft
What are the vis requirements for an ETOPS ERA?
3D: Auth vis +800
2D: Auth vis +1500
Is EAT permitted to use Cat II or III apps for ETOPS ERAs?
Not approved
What electrical cases require diversion?
- Only one gen following multiple failure (1 IDG, APU GEN or EMER GEN)
- Only one main gen available with green hyd fault (1 IDG or APU GEN)
What reasons could cause a need to divert on an ETOPs sector?
Wx LAND ASAP Failure effecting fuel burn Electrical generation problem Nav - loss of MNPS
How does Elec Emer Config increase fuel consumption?
Eng A/I valves permanently open
What speed is it assumed the final descent from FL100 will be made at?
250 kt
Why is fuel sometimes added at the critical ETP?
FOB would be less than the fuel required for the next ETOPS alternate
When is an improving BECMG applicable for an ETOPs ERA?
At the end of the BECMG time period
What is a deteriorating BECMG applicable to an ETOPS ERA?
At the start of the BECMG period
When is a PROB not limiting for an ERA?
When less than PROB40
What should be read back if ATC clears ac “via flight plan route” in oceanic clearance?
Full coordinates of the route
What does PBCS stand for?
Performance-based communications and surveillance
Are gusts included for x-wind limits for ETOPS ERAs?
Yes
After how much of a delay to departure does the time window of suitability need to be changed?
1 hour delay
What is the equation for getting the mag bearing?
True + Variation = Mag
