Over Water Flashcards
In Mission Dispatch, what WX is req for EROPS alternates
For one navaid, add 400-1 to mins For two NAVAIDS, add 200-1/2 Cat II, use 300-3/4 Cat III, use 200-1/2 **need winds in limits
What is an EROPS area
You’re more than 60 min from adequate airport at SE driftdown doped and alt in still air
Can dispatcher use lower than standard alternate minima
Yes, no lower than mins, or 200-1/2, or RVR 2400
Prior to entering EROPS area, WX from earliest landing to latest must be
At or above mins, winds in limits
What are the 2 critical scenarios on an EROPS flight plan
Range- 180 min compliant at SE speed and alt in still air
Fuel- both 2 eng and 1 eng at 10000’. Must have fuel from ETP to alternate, hold 15 min, and fly approach.
C32 Range calculation is based on
.8/310 speed cruise 230,000 lbs FL 210 427 kts **this gives a range of 1282nm
What is a NAT TMI number
Julian date
When can I SLOP
Only oceanic entry to oceanic exit
How far can I SLOP
1 or 2 right
What is a NAR
North ATlantic Route. Transitions from oceanic to domestic airspace.
What are the 3 elements of an oceanic clearance
Route, speed, level
Must hit oceanic entry
+/- 3 min
When ATC clears you for a random route, you must
Do a full read back
Send a new position report if ETA at next point changes by
3 min or more
When do I squawk 2000
30 min after oceanic entry
When is a navigation system considered failed
Disparity exceeds 25 NM (20 in pacific), notify ATC
Can I cross the NAT with one LRNS
Yes, on blue spruce routes published in NAT operations manual
If one LRNS Fails
Continue
If two LRNS Fail
Blue Spruce
Get clearance below MNPS
Divert
