Q

RVSM Altitude Rules (and acronym)

A

Reduced Vertical Separation Minimum (FL290-410)

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

23
Q

Standard IFR Alternate Minimums

A

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

24
Q

MAA

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
Q

MEA

A

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
Q

MCA

A

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
Q

MOCA

A

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
Q

MRA

A

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
Q

OROCA

A

Off Route Obstruction Clearance Alt -

30
Q

TCH

A

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
Q

RVRT

A

Touchdown RVR

32
Q

Mid-RVR

A

RVRM

33
Q

Rollout RVR

A

RVRR

34
Q

Magnetic to True Conversion rule
True to Magnetic Conversion rule

A
  1. Add east variation / subtract west
  2. Subtract east / add west (east is least)
35
Q

ALSF I / II

MALSR

A

Approach Lighting Sequence w/ sequenced flashing lights - CAT I/II configuration

Medium intensity approach lighting system w/ runway alignment indicator lights

36
Q

NOTAM (D)

A
