IFR Cross Country Flying Flashcards
What is a MEA?
Minimum Enroute Altitude
-This allows you to meet obstacle clearance requirements
- Assures acceptable VOR navigation signal coverage
What are the dinner plate end markers at an intersection on a Victor airway represent?
Represents change in
- MEA (Minimum Enroute Altitude)
- MOCA (Minimum Obstacle Clearance Altitude)
- MAA (Maximum Authorized Altitude)
If crossing a fix that indicates a change in MEA and there is no MCA do you climb before the fix or after the fix?
You would climb immediately upon reaching the fix to the new MEA if there is no MCA at the fix
What is a MAA?
Maximum Authorized Altitude
These are put in place for a number of reasons but can be for
- Airspace limitation
- Traffic conflits
- Technical issues from other ground based facilities
What is a MOCA?
Minimum Obstacle Clearance Altitude
- Lowest altitude published on airway segments
- It is the number on a Victor Airway that has an Asterisk on it and this represents the MOCA
What does the MOCA guarantee?
The MOCA guarantees:
- 1,000 ft clearance in non-mountainous areas
- 2,000 ft clearance in mountainous areas
- Assures VOR signal within 22nm
If using VOR for navigation and you are more than 22nm from the VOR you must climb up to the MEA for the route segment that you are flying
Think of a MOCA as an emergency altitude
What is an MCA?
Minimum Crossing Altitude
- Indicated by a flag with a X in it coming out of the fix
- You can find MCA’s at Nav aids, Intersections, and waypoints
- Lowest altitude to cross a fix in a direction of a higher MEA
- Must start climb before the fix in order to be at or above MCA by the time you get to the fix
- If a MCA is coming up and ATC has not given you a higher altitude request one. If no response, invoke lost comm procedure and climb while broadcasting what you’re doing until contact with ATC has been reestablished
What is a MRA and what is it for?
Minimum Reception Altitude
- Identified by a flag with an R in a box coming out of the fix
- MRA’s identify the minimum altitude to receive an off-airway radio signal to identify an intersection
- MRA’s do not apply to you if you have a IFR certified GPS because that uses satellites and internal database to determine your location.
- Intersections can be located by DME
How to determine if you are in controlled airspace
If the airspace that you are in is brownish/tan airspace then it is uncontrolled or Class G Airspace.. anything in the white is controlled airspace
What is a Transition Area?
- Class E airspace
- Upward from 700ft AGL to the base of overlaying controlled airspace
How can you get weather in route?
- ADSB-IN will allow you to access FIS-B (Flight Information Service - Broadcast) for free
- FIS-B Text reports
- METARs
- TAFs
- PIREPs
- NOTAMs
- FIS-B Text reports
- FIS-B Graphical Display
- AIRMETs
- SIGMETs
- Convective SIGMETs
- NEXRAD
- Special Use Airspace
- TFRs
- XM weather subscription
Who can you call in the air to get updated weather?
Call a flight service station.
The flight service stations frequencies are listed above the box at a VOR or location
What does the little H inside of a circle mean on a identification box for a VOR?
The “H” stands for HIWAS
H - Hazardous
I - Inflight
W - Weather
A - Advisory
S - Service
This is a voice recorded message that is broadcasted over the frequency
Where can you find information on where VOR signals might be difficult to receive or broken?
Chart Supplement
Labeled VOR Portion Unusable and will give you heading and altitude and distance that it will not be useable at or below
What is an SSV and what is it for?
Standard Service Volume
Defines the volume of airspace a VOR services
