Question 25

MEA ?

Answer 25

Minimum Enroute IFR Altitude :
The lowest published altitude between radio fixes that meets obstacle clearance requirements between those fixes and in many countries assures acceptable navigational signal coverage. The MEA applies to the entire width of the airway, segment, or route between the radio fixes defining the airway, segment, or route.

Question 26

MOCA ?

Answer 26

MINIMUM OBSTRUCTION CLEARANCE ALTITUDE (MOCA) — The lowest published altitude
in effect between radio fixes on VOR airways, off airway routes, or route segments which meets
obstacle clearance requirements for the entire route segment and in the USA assures acceptable
navigational signal coverage only within 22NM of a VOR.

Question 27

Answer 27

Independant parallel approaches : simultaneous approaches to parallel instrument runways where radar separation minima are not prescribed between aircraft using adjacent ILS.
NOZ : Normal Operating Zone
NTZ : No Transgression Zone

Question 28

Mode 2 ?

Answer 28

Dependent parallel approaches : simultaneous approaches to parallel instrument runways where radar separation minima between aircraft using adjacent ILS are prescribed.
No “NOZ” or “NTZ” concept
