INSTRUMENT EN-ROUTE PROCEDURES

Question 1

IFR ALTITUDES

Answer 1

0°-179°= ODD THOUSANDS
180°-359°= EVEN THOUSANDS

Question 2

MAA

Answer 2

MAXIMUM AUTHORIZED ALTITUDE - PUBLISHED ALTITUDE REPRESENTING THE MAXIMUM USABLE ALTITUDE OR FLIGHT LEVEL FOR AN AIRSPACE STRUCTURE OR ROUTE SEGMENT. VORs WITH THE SAME FREQUENCY MAY INTERFERE WITH EACH OTHER.

Question 3

MCA

Answer 3

MINIMUM CROSSING ALTITUDE- THE LOWEST ALTITUDE AT CERTAIN FIXES AT WHICH AN AIRCRAFT MUST CROSS WHEN PROCEEDING IN THE DIRECTION OF A HIGHER MEA. IF THERE IS A MCA AT THE FIX, YOU MUST CLIMB PRIOR TO REACHING THE FIX TO CROSS THE FIX AT MCA.

Question 4

MEA

Answer 4

MINIMUM ENROUTE ALTITUDE- THE LOWEST PUBLISHED ALTITUDE BETWEEN RADIO FIXES THAT MEETS OBSTACLE CLEARANCE REQUIREMENTS AND ASSURES ACCEPTABLE NAVIGATIONAL SIGNAL COVERAGE. CLEARANCE OF 1,000’ IN NON MOUNTAINOUS AND 2,000’ IN MOUNTAINOUS . IF THERE IS A CHANGE OF MEA WITHOUT A MCA, YOU CAN START CLIMBING AFTER YOU CROSS THE FIX WITH THE NEW MEA.

Question 5

MOCA

Answer 5

MINIMUM OBSTACLE CLEARANCE ALTITUDE- THE LOWEST PUBLISHED ALTITUDE IN EFFECT BETWEEN RADIO FIXES ON VOR AIRWAYS, OFF AIRWAYS ROUTES, OR ROUTE SEGMENTS WHICH MEETS OBSTACLE CLEARANCE REQUIREMENTS FOR THE ENTIRE ROUTE SEGMENT AND ASSURES ACCEPTABLE NAVIGATIONAL SIGNAL COVERAGE WITHIN 22 NM OF A VOR

Question 6

MRA

Answer 6

MINIMUM RECEPTION ALTITUDE- THE LOWEST ALTITUDE AT WHICH AN INTERSECTION CAN BE DETERMINED

Question 7

MSA

Answer 7

MINIMUM SAFE ALTITUDE - PROVIDES 1,000’ OF OBSTACLE CLEARANCE WITHIN A 25 NM RADIUS FROM THE NAVIGATIONAL FACILITY FOR AN INSTRUMENT APPROACH CHART; DOES NOT GUARANTEE NAVIGATIONAL SIGNAL COVERAGE.

Question 8

MVA

Answer 8

MINIMUM VECTORING ALTITUDE - PROVIDES TERRAIN AND MAN-MADE AT WHICH AN AIRCRAFT WILL BE VECTORED BY A RADAR CONTROLLER

Question 9

OROCA

Answer 9

OFF ROUTE OBSTACLE CLEARANCE ALTITUDE- PROVIDES TERRAIN AND MAN-MADE STRUCTURE CLEARANCE OF 1,000’ IN NON MOUNTAINOUS AND 2,000’ IN MOUNTAINOUS ARES WITHIN THE SECTION OUTLINED BY LATITUDE AND LONGITUDE LINES. MIGHT NOT PROVIDE NAVIGATIONAL COVERAGE OR COMMUNICATION COVERAGE.
