Q

RVSM Altitude Rules (and acronym)

Study These Flashcards
A

Reduced Vertical Separation Minimum (FL290-410)

Mag course 0-179 ODD
Mag course 180-359 = EVEN

23
Q

Standard IFR Alternate Minimums

Study These Flashcards
A

Precision App: Ceiling = 600’ and Vis 2SM
Non-precision App: Ceiling = 800 and Vis 2SM

24
Q

MAA

Study These Flashcards
A

Maximum Authorized Altitude - published altitude representing max usable alt or flight level for an airspace structure or route segment (VOR signals or military requirements above)

25
MEA
Minimum Enroute IFR Altitude - the lowest published altitude between radio fixes which assures acceptable nav signal coverage and meets obstacle clearance requirements (1000’ or 2000’)
26
MCA
Minimum Crossing Altitude- lowest alt at certain fixes which an aircraft must cross when proceeding in the direction of a higher MEA. If a normal climb after passing the fix will not assure terrain clearance.
27
MOCA
Min Obstruction Clearance Alt - lowest published alt in effect between radio fixes which meets obstacle clearance requirements AND Assures acceptable nav signal coverage only within 22 nms of a VOR (depicted w/ a T)
28
MRA
Min Reception Altitude - lowest altitude required to receive adequate signals from an off-route an aid to determine specific fixes. If DME is used to identify the fix, the MRA does not apply
29
OROCA
Off Route Obstruction Clearance Alt -
30
TCH
Threshold Crossing Height - the theoretical height above the runway threshold at which the aircraft’s glide slope antenna would be if the aircraft maintains the trajectory established by the mean ILS glide slope
31
RVRT
Touchdown RVR
32
Mid-RVR
RVRM
33
Rollout RVR
RVRR
34
Magnetic to True Conversion rule True to Magnetic Conversion rule
1. Add east variation / subtract west 2. Subtract east / add west (east is least)
35
ALSF I / II MALSR
Approach Lighting Sequence w/ sequenced flashing lights - CAT I/II configuration Medium intensity approach lighting system w/ runway alignment indicator lights
36
NOTAM (D)
(Distant) Taxiway closures, personnel and equipment near or crossing runways, and airport lighting aids that do not affect instrument approach criteria.
37
FDC NOTAMs
Flight Data Center Amendments to published IAPs and other current aeronautical charts. Advise temporary flight restrictions caused by natural disasters/large scale public events.
38
Pointer NOTAMs
Point out other NOTAMs
39
Military NOTAMS
Issued by the military through the FAA for navaids and airports
40
SAA NOTAMs
Special Activity Airspace will be active outside the published schedule times and when required by the published schedule
41
Aircraft Approach Category is based on …
1.3 times the stall speed in the landing configuration at max gross landing weight
42
Precision Approaches
ILS PAR
43
Approaches w/ vertical guidance (APV)
LPV LNAV/VNAV Baro-VNAV LDA w/ GS
44

45
MSA
Minimum Safe Altitude - Provide 1000’ obstacle clearance within 25 nm of the nav aide
46
Parallel ILS Approaches (Dependent)
At least 2500’ between runway centerlines Aircraft are staggered Radar Monitoring is not required
47
Simultaneous Parallel ILS Approaches
At least 4300’ between runway centerlines Aircraft can be side-by-side Radar monitoring is required
48
Simultaneous Close Parallel ILS Approaches
3400-4300’ between centerlines Precision radar monitoring (PRM) required
49
SOIA
Simultaneous Offset Instrument Approach Centerlines 750-2999’ apart LDA/PRM to one runway and ILS/PRM to the other LDA/PRM approach will require visual turn at MAP toward the runway
50

52
WSP
Weather System Processor
53
TWIP
