En Route Low Altitude Charts Flashcards
In the absence of a published changeover point, when to change the VOR frequency?
use the halfway point between NAVAIDS. The total distance for this segment on V20 is 73 miles. Half of 73 is 36.5.
What is the max. usable Victor Airways?
18.000
for planning purposes, what is the recommended IFR cruising altitude?
use the uncontrolled airspace IFR cruising altitude rules
What does MEA provide?
acceptable navigational signal coverage and meets obstruction clearance requirements.
MOCA
Minimum Obstruction Clearance Altitude and shown with asterisk “*”
What is MRA?
The minimum reception altitude, is the lowest altitude at which an intersection can be determined.
What is MCA?
Minumum Crossing Altitude
Interpert Following
MCA: 1,500’ when crossing toward the northeast.
X Flag: There is an MCA
MEA:11500
MOCA:6800
True/False
An MEA does not ensure two way radio communications, adequate radar coverage, or accurate DME mileage.
True
Which types of airspace are depicted on the En Route Low Altitude Chart?
Limits of controlled airspace, military training routes and special use airspace.
What is MTR?
Millitarry Training Routes
What altitude that MTR are shown?
above 1,500’ AGL.
Interpert following
One radio is tuned to TIBBY (112.0) and shows the aircraft to the right of 116° course TO. The other radio is tuned to PTN (108.3) and shows the aircraft approaching the localizer, which intersects GRICE intersection.
What is COP?
Changeover point
What is ARTCC
Air Route Traffic Control Centers
f no MCA is specified, what is the lowest altitude for crossing a radio fix,
If no MCA is specified, climb to the new MEA is required after crossing the fix.
The MEA prior to the fix is minimum altitude for crossing the fix with no MCA.
When en route on V448 from YKM VORTAC to BTG VORTAC, what minimum navigation equipment is required to identify ANGOO intersection?
One VOR
When flying from Milford Municipal to Bryce Canyon via V235 and V293, what minimum altitude should you be at when crossing CEDAR CITY VOR?
12,000 feet.
R means
This indicates a Minimum Reception Altitude (MRA). The number indicated under the intersection is MRA 7000.
