International OPS NAT Flashcards
Why were the special routes established ?
1 For short range AC
2For AC with single FMS
3For AC without HF
What are the elements of an Oceanic clearance?
1 Route
2Altitude
3Speed
In AFRICA what VHF and pos format?
126.9 All station this is (call sign) FL - "Northbound, From-To, via airway Pos ... at .....(UTC) Call Sign - again - FL
What SQ in NAT and when?
SQ 2000 after cost out
Altimeter check
Cost out - Primary alt must agree within 200 ft
If not - request new clearance to avoid RVSM
One hour interval check
NAT clearance M number
Controller may issue -.02 +.01 M from the filled
Pilots must strictly adhere to the assigned TRUE M / Not indicated
What is SLOP and where should be applied
1 Used in all oceanic airspace
2 Established to avoid mid air collisions
3 Offset 1 or 2 NM RIGHT only
4 No ATC clearance required
5 Apply offset at cost out - get back on track at cost in
6 POS reports based on the clearance , NOT actual coordinates
Avoid wake turbulence
HF freq are better?
The smaller the hour the smaller the Freq
RVSM contingency PROC
Must notify ATC when
1 No longer RVSM compliant due to equip failure
2 Loss of redundancy in altimeters
3 Turbulence that affects the FL
4 Cannot maintain ALT for any other reason
B-RNAV
1 +/- 5 NM for 95% of the flight time
2 Must be able to perform a RAIM checkoff more than 5 min for all the B-RNAV portion of the flight
What is the lateral tolerance on a V airway in USA
4 NM
Proof of B-RNAV
1 Non -comercial - B-RNAV or RNAV5 approval statement in the AFM Limitation or Navigational supplement
LOA not required
2 Comercial OPS - Need ops Specs for B-RNAV approval
P-RNAV must satisfy
1NM for the 95% of the intended track / flight time
P-RNAV is
1 Used only in terminal areas - STAR / SID 2 Lateral & Longitudinal Nav 3 Is NOT mandatory 3 Requires integrity check by the crew 4 Based on WGS -84 coordinates 5 Temp correction not addressed 6 Dual P-RNAV req identified in AIP
Getting approval for P-RNAV
2 way process
AFM - Aircraft is P-RNAV approved
and
Formal approval by the state of registry : USA 91 LOA / 135 Op Spec approval
If you are crossing North ATL at FL 370, what are your minimum separations from other aircraft?
60 NM horizontal
10 min in trail
and
1000 ft vertical
What factors influence HF communication?
Time of the day and
Solar flare activity
If a controller issued a .79 M to cross Alt what you must do?
.79 True Mach
During the pre-flight , each alt must agree within …ft of the AP elevation
75 ft
What overwater survival equipment is req for FAR 91?
Life rafts, life preservers and survival kits
On the req flight plan is crossing at .80 Mach.
What speed could be expected cleared by ATC?
.78 - .81 M
What navigation eq one needs for unrestricted MNPS ops?
2 Long range navigation
in oceanic ops using SLOP you should
Fly centerline or 1NM or 2NM right of track
you are cleared to cross NA via NAT U FL 370 M.80
How would yo confirm this clearance?
Read back exactly the clearance as given, followed by the TIM number
Once in the NA Oceanic airspace and beyond the radar coverage you should
SQ 2000
Monitor 121.5 & 123.45
If yo are crossing the NA from US to Europe at FL350 & will cross 30W at 0230Z yo are flying?
En eastbound organized track
Flying from US to Europe, Are yo required to use posing chart?
Yes. Route is more than 725 NM between ground based nav aids
What min eq is req to fly special routes through Iceland?
At least 1 Long Range nav system
After entering the oceanic space , you loose all of your nav systems
What you should do first?
Notify ATC
If yo are IMC and under radar control and lose comm and yo flight plan includes a climb ?
SQ7600 & Climb after 7 min
if you cannot contact Gander radio on HF
Where could obtain alt fq from?
Atlantic Orientation chart using family B fq
ICAO doc 8168 stats that in the event of a TICAS RA pilot shall
Follow the RA even if there is a conflict with ATC instructions
B-RNAV in Europe is ?
+/- 5 NM 95% of the flight time
QFE altimeter setting is in reference to
RWY
If a minor discrepancy on a SAFA is detected
No immediate action is required
QNH is reference to?
MSL
Climbing out of European AP when would one change to STD the ALT?
Passing the T ALT
what is the difference between
altitude and heights?
Alt - MSL
Height - RWY
What constitutes qualification to fly Canadian RNP airspace?
MNPS approval
You are flying NA at Fl370 and you lose press. what to do?
Follow ICAO doc 4444 proc
