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. This figure is then rounded to the nearest 100 foot increment, i.e. 2,049 feet becomes ...
Instrument rating refers to the qualifications that a pilot must have in order to fly under instrument flight rules (IFR). It requires specific training and instruction beyond what is required for a private pilot certificate or commercial pilot certificate, including rules and procedures specific to instrument flying, additional instruction in meteorology, and more intensive training in flight ...
Under FAR 61.57, to be eligible to fly in Instrument Meteorological Conditions (IMC) an IFR-rated pilot must accomplish and log at least the following IFR procedures under actual or simulated IMC every 6 months: 6 instrument approaches. Holding procedures. Intercepting and tracking courses through the use of navigation systems.
A clearance always specifies a clearance limit, which is the farthest the aircraft can fly without a new clearance. In addition, a clearance typically provides a heading or route to follow, altitude, and communication parameters, such as frequencies and transponder codes. In uncontrolled airspace, ATC clearances are unavailable.
In aviation, a minimum crossing altitude (MCA) is the lowest altitude at which a navigational fix can be crossed when entering or continuing along an airway that will allow an aircraft to clear all obstacles while carrying out a normal climb to the required minimum en route IFR altitude (MEA) of the airway in question beyond the fix.
Minimum en route altitude (MEA), [1] alternately spelled as Minimum enroute altitude, [2] is the lowest published altitude between radio navigation fixes that assures acceptable navigational signal coverage (see MRA) and meets obstacle clearance requirements (see MOCA) between those fixes.
This practice can also be used by showing people silent reviews and having them interpret the message the creator is trying to convey, making them a great teaching tool, according to Paul.
The initial altitude is sometimes stated on the charts. If not, it will be given by the air traffic controller. The departure frequency is given to the pilot when ATC hands the aircraft over to the next sector. A typical IFR clearance would be: OOABC, cleared to Ostend via the DENUT 7C departure, climb flight level six zero, squawk four six ...
