Often asked: How To Read Change Over Point Aviation?

What is change over point in aviation?

Changeover Points (COP) The COP is a point along the route or airway segment between two adjacent VORs where changeover in navigation guidance should occur. At this point, the pilot should change the navigation receiver frequency from the station behind the aircraft to the station ahead.

Why are changeover points established?

Changeover points are established to provide an optimum balance in the signal strength and quality between facilities at all levels to be used and to ensure a common source of azimuth guidance for all aircraft operating along the same portion of a route segment.

What is the difference between MEA and MOCA?

Both the MEA and MOCA provide the same obstruction clearance. The only differ- ence is that radio navigation signal coverage is provided along the entire airway segment at the MEA, but the MOCA provides radio navigation signal coverage only within 22 nautical miles of the VOR.

What is MCA in aviation?

Minimum Crossing Altitude ( MCA ). An MCA is the lowest altitude at certain fixes at which the aircraft must cross when proceeding in the direction of a higher minimum en route IFR altitude.

What is a TEC route?

In United States aviation, tower en route control ( TEC ) is a collection of published low-altitude, short-distance IFR routes through large metropolitan areas that require no level of air traffic control higher than approach-control facilities.

What does minimum enroute altitude guarantee?

Put simply, the MEA is the lowest altitude to be flown in an airspace structure which assures: reception of navigation aids necessary to navigate accurately along the required route, two-way communication with air traffic control, safe clearance from obstacles within the sector, and.

When not in radar contact should you always report?

When not in radar contact (and without a specific request), the pilot should report to ATC when leaving the final approach fix inbound on final approach. 4. In the absence of an assigned route or a route that ATC has advised may be expected in a further clearance, by the route filed in the flight plan.

What is magnetic reference bearing?

Magnetic Reference Bearing (MRB) is the published bearing between two waypoints on an RNAV/GPS/GNSS route. The MRB is calculated by applying magnetic variation at the waypoint to the calculated true course between two waypoints.

Where is the minimum IFR altitude?

In a DMA, the minimum altitudes for IFR flight (explicitly defined in 14 CFR §91.177) must be 2,000 feet above the highest obstacle within a horizontal distance of 4 nautical miles from the course to be flown.

What is the minimum reception altitude?

In aviation, minimum reception altitude (MRA) is the lowest altitude on an airway segment where an aircraft can be assured of receiving signals from off-course navigation aids like VOR that define a fix.

What is minimum turning altitude?

Minimum turning altitude (MTA) is a charted altitude providing vertical and lateral obstruction clearance based on turn criteria over certain fixes, NAVAIDs, waypoints, and on charted route segments.

What is a victor line?

Victor airways are depicted as black solid lines on IFR Low-Altitude Enroute charts and as thick faded blue lines on VFR Terminal and Sectional Area charts. They are identified by a number, similar to an interstate highway (for example, a pilot could say that he/she is “flying Victor Eight”).

Can you fly IFR without VOR?

The federal aviation regulations, specifically 14 CFR 91.205, detail the equipment needed for different flight conditions, such as day VFR, night VFR, IFR, etc. The answer is obviously no for the pilot flying IFR solely (from a legal perspective) in reliance on the VORs.

Can you use GPS for Victor Airways?

Most IFR pilots routinely fly victor airways using only GPS. As a practical matter, if you have a navigator that supports airways (for example, a GTN or newer G1000 system) and ATC clears you to fly the “unusable” segment via SAGES -> WIGAN, you would probably still load V292 into the box.
