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
2 LRNS Fail after oceanic entry
Continue with clearance. Talk to ATC
What if I lose all navigation systems
Dead Reckon Talk- HF, 121.5 Lights on, TCAS Change altitude 500' Look for other aircraft to follow
What is radio term for distress? Urgency?
Mayday
Pan Pan
What to do in all emergencies
Communicate-CPDLC, HF, Satcom, 121.5, 123.45. Lights TCAS Offset 15NM Change alt 500'
How do I turn off course in an emergency
Turn 45 off in safer direction, maintain alt if possible until 10nm offset, then maintain 500’ alt difference and 15nm offset
How do I deviate around WX
Get clearance. Up to 10nm, maintain alt. Then Climb 300’ south or descend 300’ north.
How do I avoid wake turb
SLOP
How many LRNS for overwater
2
When must I do a time check
On the ground
For RVSM, altimeters must agree within
200’
Crosscheck altimeters every
1 hour
If one LRNS fails after oceanic entry
Continue with clearance, notify ATC
If all LRNS fail after oceanic entry
Climb or descend 500' Tell ATC Call 121.5 Lights TCAS
Always report
Leaving altitudes, reaching altitudes
How do I SLOP
1 or 2 nm right of course, oceanic entry to exit
Max climb rate
1000’ per min
If deviate from route, must regain it within
100 nm
Call ATC if estimate is off by
3 min or more
Should I hold at oceanic entry point waiting for clearance?
No , press. Except Shanwick.
Do I have to do a full clearance read back
Random- yes
OTS- no, but include TMI
When can I request oceanic clearance
90 min to 30 min prior coast out
If departure is less than 45 min from oceanic entry, get clearance
10 min prior to startup
3 parts of oceanic clearance
Route
Flight level
Mach number
Hit oceanic entry point
+- 3 min
How do I deviate around WX if no clearance
10 nm, climb 300’ if south
Call 121.5, 123.45
Lights
TCAS
When do I squawk 2000
30 min after oceanic entry
Steps in an emergency
“Pan, Mayday”, get clearance if able
Turn 45 off, offset 15nm, change alt 500’
Lights
TCAS
Where do I fly an emergence descent
Turn 45 off, 15nm offset, then fly midway between the tracks
If diverting, descend below
280
When do I Logon to CPDLC
45-15 min prior to oceanic entry
