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

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

What is the primary update for the 737 FMC?

A

GPS

if unvavailable it revers to IRS…Radio updating is available if enabled on the NAV options page..then IRS is last

30
Q

IF GPS becomes unavailable as the primary source of the FMC

A

it reverts to IRS
Radio updates are inhibited by default
NAV OPTIONS= DME IS OFFss

31
Q

Check on NAV Status what is currently used

A

GPS (2) and IRS (2) means both are in use

32
Q

UNABLE REQD NAV PERF-RNP

A

only rnp navigation specifications require alerting..so wont happen during normal en route flight

33
Q

Where can i get essential RNP information?

A

Progress Page 4/4

34
Q

Tuiflys vertical RNP limit is

A

125ft

35
Q

Where can I shift the FMC to another reference?

A

POS SHIFT 3/3

36
Q

Wie komme ich zu NAV Options

A

REF NAV DATA oder bei NAV STATUS Pages…with DME OFF and LOC,VOR,GPS ON the last mentioned three are still OFF

37
Q

NPS-Navigation Performance Scales: What does it show?

A

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
Q

Weiße Scale beim NPS

A
  • innereres ende zeigt ANP
  • äußeres zeigt derzeitige FMC RNP

wenn genauerwird dann wird balken nach innen größer—außen bleibt immer gleich

39
Q

FMC vertical RNP

A

Tuifly has 125ft—max deviation is 75ft

40
Q

if ANP exceeds RNP or if ANP plus FTE exceeds RNP

A

after 5s-the bars turn amber

without suitable reference G/A

41
Q

VNAV deviation scale on the ND—range?

A

plus/minus 400ft

42
Q

IAN indication become more sensitive approaching the RWY

A

LNAV does not

43
Q

IAN warnings

A

visual and aural alerts if the AP remains enaged beow 100ft

44
Q

IAN approaches are designed to beflown to pubslished

A

CAT 1 minimums

45
Q

LNAV/VNAV approach

A

VNAV will only calculate to MAPt not further like IAN

46
Q

ABAS

A

RAIM is other form of ABAS—TUIFLY is capable

47
Q

SBAS

A

TUIFLY is not equipped

48
Q

GBAS

A

Tuifly has some GBAS /GLS receivers…approaches are in FRA and BRE

49
Q

Chartet PBN procedures are not standardized yet

A 
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
Q

RF written on chart?

A

Radius to FIX requirements—TUIFLY can do it

51
Q

IAN may not be used if a

A

cold temperature correction for the approach has to be applied

52
Q

Funkspruch wenn RNP nicht eingehalten werden kann?

A

Unable RNP

53
Q

Funkspruch wenn RNAV arrival or departure nicht akzeptiert werden kann

A

UNABLE RNP23 Departure/Arrival due to RNAV TYPE

54
Q

Preflight RAIM prediction (if procedure requires updates)

A

RAIM predication hasto be valid at least until ETA+15min

No outages of more than 5min is allowable–check notam

55
Q

Where can you check the RAIM prediction?

A

Easy Brief–RAIM report

Change mask angle to 5
Appendto EasyBriefPDF
Check ETA plus 15min is within Scenaria END^^

56
Q

RNAV/RNP procedures may require cold temperature corrections

A

below 0 OAT
to all minim alt-DA/MDA has to be set to new value
but not ATC alt and BARO VNAV

57
Q

When dont you have to correct for cold temp?

A

BARO VNAV approach

58
Q

RNP APCH

A

Use of FD or AP is mandatory until suitable visual refernce is established

59
Q

2 FMC are required to…

A

fly RNP approaches,not a dispatch requirement

60
Q

1 FMC is sufficient for…

A

RNAV procedures…all RNAV approaches are RNP and need therefore 2 FMCs…,not a dispatch requirement

61
Q

RNP approach can be flown down to..

A

LNAV or VNAV minima

LNAV=MDA plus 50ft, only lateral guidance
VNAV=DA, plus vertical guidance
LPV=SBAS, not approved

62
Q

Prior conduct of RNP approach…

A
  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
Q

RNP approach

A

DIRECT TO FAF is prohobited (2nm minimum)

64
Q

RNP approach:AP

A

is strongly recommonded

65
Q

Change of RNP value only if…

A

ONLY if it s wrong or does not phase in

otherwise the RNP for missed approach is not set automatically to 1.0!!!!!

66
Q

RNP approach G/A reasons

A
  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
Q

RNP approach down to VNAV minima

A

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
Q

Was muss man zusätzlich bei einem RNP Approach mit VNAV Baro Minimum zu den 0.3nm noch checken?

A

FMC RNP Progress Page 4/4 ob value unten rechts auf 125 steht (VRNP)

69
Q

G/A bei RNP approaches wann?

A

1 dot deviation (and unable to switch to other non RNAV procedure) or UNABLE REQD NAV PER-RNP

70
Q

Wie weit vorher muss man bei einem RNP approach iden final approach course intercepten=

A

2nm for FAF mit weniger als 45° intercept angle

71
Q

Bei jedem RNP (inkludiert RNAV)

A

braucht man 2 FMC

72
Q

Bei RNP approach mit BARO VNAV MIN

A

keine cold temp correction!
