How much clearance does a MOCA give you?
|Terrain Elevation||Obstacle Clearance|
|3000 ft – 5000 ft (900 m – 1500 m)||1500 ft (450 m)|
|Greater than 5000 ft (1500 m)||2000 ft (600 m)|
How is MOCA calculated?
The MOCA seen on the NACO en route chart, may have been computed by adding the required obstacle clearance (ROC) to the controlling obstacle in the primary area or computed by using a TERPS chart if the controlling obstacle is located in the secondary area.
What is difference between MOCA and MEA?
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.
Is the MOCA higher than the MEA?
2 Answers. You are right. Within 22 nautical miles of the VOR, there is no practical difference between an MEA and a MOCA.
What does a MOCA guarantee?
The MOCA is the lowest published altitude in effect between radio fixes on VOR airways, off-airway routes, or route segments that meets obstacle clearance requirements for the entire route segment. This altitude also assures acceptable navigational signal coverage only within 22 NM of a VOR.
What is the difference between Mora and Oroca?
MORA (minimum off-route altitude). The OROCA (minimum off route obstruction clearance altitude) on the U.S. government’s IFR en route charts serves the same purpose, except clearances are 1,000 feet in non-mountainous areas and 2,000 feet in designated mountainous areas.
Can I take a MoCA test online?
The official version of the test, in fact, will not be available after September 2020 to anyone who has not received proper certification, according to the MoCA organization. Despite this, the actual test can be found online today.
Is MoCA AGL or ASL?
Define MOCA. MOCA (Minimum Obstacle Clearance Altitude) – Altitude ASL between specified fixes on airways and air routes that meets the IFR obstacle clearance requirements.
Where is the minimum crossing altitude?
The MCA is related with signal reception and obstacle clearance; this will be indicated by a flagged [X] on NOS and Jeppesen charts as an airway number and altitude. The pilot should climb to the MCA before reaching the intersection; in that way the MCA will not be violated.
What is 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.
Can you fly below the MEA?
allow[s] IFR certified Global Navigation Satellite System (GNSS) equipped aircraft to be cleared below published Minimum En Route Altitudes ( MEA )… The notice explained that: For aircraft using VOR, VORTAC or TACAN for navigation, this [i.e., flying at the MOCA] applies only within 22 miles of that NAVAID.
What is minimum vectoring altitude?
Minimum Vectoring Altitude (MVA) is the lowest altitude, expressed in feet AMSL (Above Mean Sea Level (MSL)), to which a radar controller may issue aircraft altitude clearances during vectoring /direct routing except if otherwise authorized for radar approaches, departures and missed approaches.
What is MAA altitude?
The maximum authorized altitude ( MAA ) is the highest altitude at which the airway can be flown with assurance of receiving adequate navigation signals.
What is Mora and MOCA?
MOCA ensures you obstacle clearance throughout the route but reception only when within 22nm from the navaid defining the route. MORA is a jeppesen derived altitude that ensures you obstacle clearance when within the square.
