FAA Navigation Aids (NAVAIDs) 3

Question 1

On a sectional chart, the mileage shown between two waypoints along a Victor airway is measured in what units?

Accepted Answer

Nautical miles

Answer

Statute miles

Answer

Kilometers

Answer

Nautical miles rounded to statute miles

Question 2

What does 'MEA' printed alongside a Victor airway on a sectional chart stand for?

Accepted Answer

Minimum Enroute Altitude

Answer

Maximum Expected Altitude

Answer

Minimum Established Airway

Answer

Mean En route Altitude

Question 3

What is the purpose of the 'MOCA' value sometimes shown along Victor airways on sectional charts?

Accepted Answer

It is the Minimum Obstacle Clearance Altitude, guaranteeing terrain clearance but only NAVAID reception within 22 nm of a VOR

Answer

It is the Maximum Operating Ceiling Altitude for the airway

Answer

It is the Minimum Off-route Clearance Altitude for IFR diversions

Answer

It is the Mean Obstacle Clearance Altitude for VFR planning

Question 4

On a sectional chart, an 'off-route obstruction clearance altitude' (OROCA) value in a grid box ensures what?

Accepted Answer

1,000 feet above highest obstacle in non-mountainous areas; 2,000 feet in designated mountainous areas

Answer

500 feet above the highest terrain only

Answer

Clearance only within the grid square boundaries

Answer

Clearance up to 18,000 feet MSL

Question 5

On a sectional chart, what does 'T' printed in the corner of a NAVAID data box signify?

Accepted Answer

Terminal VOR with limited service volume (25 nm, 12,000 feet)

Answer

TACAN-only station, no civil use

Answer

Transponder required in that airspace

Answer

Tower with collocated NAVAID

Question 6

On a sectional chart, what does a change in the MEA value along a Victor airway at a fix indicate?

Accepted Answer

The minimum IFR altitude changes at that point due to terrain or NAVAID coverage differences

Answer

A frequency change is required at that fix

Answer

A mandatory holding pattern exists at that fix

Answer

The airway width changes at that fix
