Enroute Altitude Flashcards
Minimum enroute altitude MEA
Lowest published altitude between radio fixes, obstacle clearance, single coverage
Minimum obstruction clearance altitude MOCA
Lowest published altitude between radio fixes on VOR airways, navigational signal within 22 nautical miles of VOR, Obstacle clearance
Minimum crossing altitude MCA
Minimum altitude aircraft must cross
Minimum reception altitude MRA
Lowest altitude an intersection can be determined
Maximum authorized altitude MAA
Maximum altitude with adequate reception of navigation aid signal
OROCA off-route obstruction clearance altitude
Obstacle clearance within 1,000 foot buffer in non-mountainous area and 2,000 in mountainous area
What items of information should be included in every position report?
Identification Position Time Altitude or flight Level Type of flight plan (not required in IFR position report with ARTCC or Approach control) ETA and name of next checkpoint Name of checkpoint after next Pertinent remarks
What operational procedures must pilots on IFR flight plans adhere to when operating VFR-on-top?
- VFR altitude, visibility and distance from cloud
- Comply with IFR rules (minimum IFR altitude, position reporting, radio communication, ATC clearance)
What regulations apply concerning supplemental oxygen?
Above 12,500 up to and including 14,000 - flight crew after 30 minutes
Above 14,000 up to and including 15,000 - flight crew
Above 15,000 - flight crew, passengers must be provided with oxygen
If an emergency action requires deviation from 14 CFR part 91, must a pilot submit a written report, and if so, to whom?
If requested by ATC, within 48 hours submit report to the manager of that ATC facility
On a direct flight not flown on radials or courses of established airways or routes, what points serve as compulsory reporting points?
Pilots must report over each reporting point used in the flight plan to defined the route of flight.
Why is it important for the pilot to receive an EFC time with initial holding instructions?
In case you lose two way radio communication, you know when to leave the holding fix
What action is appropriate when approaching a holding fix at an airspeed in excess of maximum holding speed?
Start a speed reduction when 3 minutes or less from the fix. Speed may be reduced earlier, but ATC must be advised of the change.
What is the leg length for a standard holding pattern?
1 minute inbound at or below 14,000 MSL
1 1/2 minutes inbound above 14,000 MSL
What are the designated altitudes for the airways in the VOR and L/MF airway system?
1,200 feet above the surface up to but not including 18,000 feet MSL
