Instruments

Question 1

Concerning VORs, what is the only positive method of identification and what is the course accuracy?

Answer 1

-Morse Code Identifier or Recorded Automatic Voice ID
-Course Accuracy +/- 1 degree not to exceed 2.5 degrees

Question 2

MIA (Minimum IFR Altitude)

Answer 2

-Altitudes published for standard instrument approach procedures
-min 2000 mountains / 1000 non-mountain

Question 3

MEA (Minimum Enroute Altitude)

Answer 3

-Lowest published altitude between radio fixes which assures acceptable NAV signal coverage and meets obstacle clearance requirements between those fixes

Question 4

MOCA (Minimum Obstruction Clearance Altitude)

Answer 4

-The lowest published altitude in effect between radio fixes on VOR airways, obstacle clearance requirements and assures acceptable NAV signal coverage only within 25 statue miles

Question 5

Define DA/DH

Answer 5

The height at which a decision must be made during a precision approach to continue the approach or execute missed approach

Question 6

OROCA (Off Route Obstruction Clearance Altitude)

Answer 6

Off route altitude which provides clearance 1,000’ buffer / 2000’ buffer in mountains terrain. May not provide signal coverage from navaids

Question 7

MRA (Minimum Reception Altitude)

Answer 7

The lowest altitude required to receive adequate signals to determine specific VHF omnirange / tactical air navigation fixes

Question 8

MCA (Minimum Crossing Altitude)

Answer 8

The lowest altitude at certain fixes at which an aircraft must cross when proceeding in the direction of a higher minimum enroute instrument flight rules altitude (MEA)

Question 9

MVA (Minimum Vectoring Altitude)

Answer 9

The lowest mean sea level altitude at which an IFR aircraft will be vectored by a radar controller, except as otherwise authorized for radar approaches, departures and missed approaches
