Q

Requirements of the three types of procedures related to RNAV

A

1.RNP=2 FMC and onboard performance monitoring and alerting
2.RNAV=1FMC and no onboard performance….
3.RNAV overlay=conventional proecdure …Tuning
required

THERE IS NO RNAV APPROACH SPECIFICATION: EVERY RNAV APPROACH IS AN RNP APPROACH
EVERY RNP APPROACH REQUIRED DUAL FMC

Q

Special navigation equipment is required for RNAV and RNP operations

A

Check DDG/MEL Preamble…those are not dispatch requirements! they only have to be servieable in order to fly the procedure, use others instead.

RNP operations are currently revuces in company NOTAM

Q

ANP VS RNP

A

RNP=Minimum required position quality, from procedures being used
ANP=Position certainty, from onboard sensors being used
RNP requires that ANP is lower than RNP

Q

FMC supplies default RNP valuesfor oceanic,en route terminal and approach

A

oceaning RNP-12nm
En route RNP-2nm
Terminal RNP-1nm
Approach RNP-0.3nm

may be entered manually by crew
UNABLE REQD NAV PERF is the message

25
How can you get the acutal RNP?
POS SHIFT, RNP PROGRESS 4/4 and RTE LEGs pages
26
VRNP
same as RNP being used by FMC, dont enter it manually
27
VANP-Vertical Actual Navigation Performance VANP
FMC is 99.7% certain that altitude is in right band Correct Baro setting is Important!! Not the one on descend forceast
28
FMC switch in normal
Left is primary, both are however combined
29
What is the primary update for the 737 FMC?
GPS | if unvavailable it revers to IRS...Radio updating is available if enabled on the NAV options page..then IRS is last
30
IF GPS becomes unavailable as the primary source of the FMC
it reverts to IRS Radio updates are inhibited by default NAV OPTIONS= DME IS OFFss
31
Check on NAV Status what is currently used
GPS (2) and IRS (2) means both are in use
32
UNABLE REQD NAV PERF-RNP
only rnp navigation specifications require alerting..so wont happen during normal en route flight
33
Where can i get essential RNP information?
Progress Page 4/4
34
Tuiflys vertical RNP limit is
125ft
35
Where can I shift the FMC to another reference?
POS SHIFT 3/3
36
Wie komme ich zu NAV Options
REF NAV DATA oder bei NAV STATUS Pages...with DME OFF and LOC,VOR,GPS ON the last mentioned three are still OFF
37
NPS-Navigation Performance Scales: What does it show?
Shows deviation from desired track (flight technical error/cross track error)--magenta pointer ANP-white scale moving inwards as ANP increases Äußerer Rand der weißen Balken zeigt FMC RNP
38
Weiße Scale beim NPS
- innereres ende zeigt ANP - äußeres zeigt derzeitige FMC RNP wenn genauerwird dann wird balken nach innen größer---außen bleibt immer gleich
39
FMC vertical RNP
Tuifly has 125ft---max deviation is 75ft
40
if ANP exceeds RNP or if ANP plus FTE exceeds RNP
after 5s-the bars turn amber | without suitable reference G/A
41
VNAV deviation scale on the ND---range?
plus/minus 400ft
42
IAN indication become more sensitive approaching the RWY
LNAV does not
43
IAN warnings
visual and aural alerts if the AP remains enaged beow 100ft
44
IAN approaches are designed to beflown to pubslished
CAT 1 minimums
45
LNAV/VNAV approach
VNAV will only calculate to MAPt not further like IAN
46
ABAS
RAIM is other form of ABAS---TUIFLY is capable
47
SBAS
TUIFLY is not equipped
48
GBAS
Tuifly has some GBAS /GLS receivers...approaches are in FRA and BRE
49
Chartet PBN procedures are not standardized yet
``` OLD-NEW RNAV (GNSS)APCH-RNP AP RNAV (RNP) APCH-RN AR APCH RNP 10-RNAV 10 B-RNAV-RNAV 5 P-RNAV-RNAV 1 ```
50
RF written on chart?
Radius to FIX requirements---TUIFLY can do it
51
IAN may not be used if a
cold temperature correction for the approach has to be applied
52
Funkspruch wenn RNP nicht eingehalten werden kann?
Unable RNP
53
Funkspruch wenn RNAV arrival or departure nicht akzeptiert werden kann
UNABLE RNP23 Departure/Arrival due to RNAV TYPE
54
Preflight RAIM prediction (if procedure requires updates)
RAIM predication hasto be valid at least until ETA+15min | No outages of more than 5min is allowable--check notam
55
Where can you check the RAIM prediction?
Easy Brief--RAIM report Change mask angle to 5 Appendto EasyBriefPDF Check ETA plus 15min is within Scenaria END^^
56
RNAV/RNP procedures may require cold temperature corrections
below 0 OAT to all minim alt-DA/MDA has to be set to new value but not ATC alt and BARO VNAV
57
When dont you have to correct for cold temp?
BARO VNAV approach
58
RNP APCH
Use of FD or AP is mandatory until suitable visual refernce is established
59
2 FMC are required to...
fly RNP approaches,not a dispatch requirement
60
1 FMC is sufficient for...
RNAV procedures...all RNAV approaches are RNP and need therefore 2 FMCs...,not a dispatch requirement
61
RNP approach can be flown down to..
LNAV or VNAV minima LNAV=MDA plus 50ft, only lateral guidance VNAV=DA, plus vertical guidance LPV=SBAS, not approved
62
Prior conduct of RNP approach...
1. Direct IF is acceptable if the track change is lower than 45° 2. Radar vectors outsie the FAF is acceptalble if final track is intercepted 2nm prior FAF DIRECT TO FAF is prohibited CHECK EFIS QNH
63
RNP approach
DIRECT TO FAF is prohobited (2nm minimum)
64
RNP approach:AP
is strongly recommonded
65
Change of RNP value only if...
ONLY if it s wrong or does not phase in otherwise the RNP for missed approach is not set automatically to 1.0!!!!!
66
RNP approach G/A reasons
1. below MSA and more than 1 dot deflection in full scale mode 2. Radio/Instrument failure which affect ability 3. DUAL FMC failure 4. UNABLE REQD NAV PER 5. if ac has NPS.Amber deviation alert and anable to change to a non RNP procedure
67
RNP approach down to VNAV minima
1.no cold temp corrections! if below procedure design temperature use LNAV minima 2.no additional 50ft required 3.Maximum vertical deviation is 75ft check FMC RNP Progress page 4/4 during approach briefing is the VRNP value is set to 125ft (rechts unten) 4.Correct altimter settings is essential
68
Was muss man zusätzlich bei einem RNP Approach mit VNAV Baro Minimum zu den 0.3nm noch checken?
FMC RNP Progress Page 4/4 ob value unten rechts auf 125 steht (VRNP)
69
G/A bei RNP approaches wann?
1 dot deviation (and unable to switch to other non RNAV procedure) or UNABLE REQD NAV PER-RNP
70
Wie weit vorher muss man bei einem RNP approach iden final approach course intercepten=
2nm for FAF mit weniger als 45° intercept angle
71
Bei jedem RNP (inkludiert RNAV)
braucht man 2 FMC
72
Bei RNP approach mit BARO VNAV MIN
keine cold temp correction!
