CHAPTER 7 - EN ROUTE QUESTIONS
& ANSWERS
What is the definition of MEA? - Correct Answers -The lowest published altitude which
meets obstacle clearance requirements and assures acceptable navigational signal
coverage
The altitude that provides acceptable navigational signal coverage for the route, and
meets obstacle clearance requirements, is the minimum - Correct Answers -enroute
altitude
Reception of signals from an off-airway radio facility may be inadequate to identify the
fix at the designated MEA. In this case, which altitude is designated for the fix? - Correct
Answers -MRA
Which condition is guaranteed for all of the following altitude limits: MAA, MCA, MRA,
MOCA, and MEA? - Correct Answers -1,000 foot obstacle clearance
If no MCA is specified, what is the lowest altitude for crossing a radio fix, beyond which
a higher minimum applies? - Correct Answers -The MEA at which the fix is approached
MEA is an altitude which assures - Correct Answers -acceptable navigational signal
coverage and meets obstruction clearance requirements
Reception of signals from a radio facility, located off the airway being flown, may be
inadequate at the designated MEA to identify the fix. In this case, which altitude is
designated for the fix? - Correct Answers -MRA
ATC may assign the MOCA when certain special conditions exist, and when within -
Correct Answers -22 NM of a VOR
The lowest published altitude which meets obstacle clearance requirements and
assures acceptable navigational signal coverage is the - Correct Answers -MEA
Acceptable navigational signal coverage at the MOCA is assured for a distance from the
VOR of only - Correct Answers -22 NM
, What obstacle clearance and navigation signal coverage is a pilot assured with the
minimum sector altitudes depicted on the IAP charts? - Correct Answers -1,000 feet
within a 25 NM radius of the navigation facility but not acceptable navigation signal
coverage

Correct Answers -IFR Low Altitude En Route Chart
(Refer to Figure 214.) Which enroute low altitude navigation chart would cover proposed
IFR routing departing from Billing Logan International (BIL) - Correct Answers -L-13D
(Refer to Figures 65 and 67.) What is the significance of the symbol at GRICE
intersection? - Correct Answers -The localizer has an additional navigation function
(Refer to Figure 89.) What is the ARTCC discrete frequency at the COP on V208
southwest bound from HVE to PGA VOR/DME? - Correct Answers -127.55
(Refer to Figure 47.) En route on V112 from BTG VORTAC to LTJ VORTAC, the
minimum altitude crossing Gymme intersection is - Correct Answers -7,000 feet
(Refer to Figure 91.) What is the function of the Great Falls RCO (Yellowstone vicinity)?
- Correct Answers -Remote communications outlet for Great Falls FSS
(Refer to Figure 24.) For planning purposes, what would be the highest MEA on V187
between Grand Junction Regional (GJT) and Durango Animas Air Park (00C)? - Correct
Answers -15,000 feet
(Refer to Figure 24.) What is the MOCA between JNC and HERRM intersection on
V187? - Correct Answers -12,100 feet
(Refer to Figure 47.) When en route on V448 from YKM VORTAC to BTG VORTAC,
what minimum navigation equipment is required to identify ANGOO intersection? -
Correct Answers -One VOR receiver
(Refer to Figure 47.) En route on V468 from BTG VORTAC to YKM VORTAC, the
minimum altitude at TROTS intersection is - Correct Answers -11,500 feet
Which types of airspace are depicted on the En Route Low Altitude Chart? - Correct
Answers -Limits of controlled airspace, military training routes and special use airspace
(Refer to Figure 34.) For planning purposes, what is the highest useable altitude for an
IFR flight on V573 from the HOT VORTAC to the TXK VORTAC? - Correct Answers -
16,000 feet
