remote (slave) scope . required navigation performance (RNP
usually the same warranty and guarantee as a new
engine.
remote (slave) scope - A cathode-ray tube that
duplicates the display of a primary radar scope.
remote communications airlground (RCAG) facility
- An unmanned VHF/UHF transmitter1 receiver
facility used to expand ARTCC air1 ground
communications coverage and to facilitate direct
contact between pilots and controllers. RCAG facilities
are sometimes not equipped with emergency
frequencies 12 1.5 MHz and 243.0 MHz.
remote communications outlet(RC0) - An unmanned
communications facility remotely controlled by air
traffic personnel. RCOs serve FSSs. RTRs (Remote
Transmittermeceivers) serve terminal ATC facilities.
An RCO or RTR can be UHF or VHF and will extend
the communication range of the air traffic facility.
There are several classes of RCOs and RTRs. The class
is determined by the number of transmitters or
receivers. Classes A through G are used primarily for
airlground purposes. RCO and RTR class 0 facilities
are nonprotected outlets subject to undetected and
prolonged outages. RCO (0's) and RTR (0's) were
established for the express purpose of providing
ground-to-ground communications between air traffic
control specialists and pilots located at a satellite
airport for delivering enroute clearances, issuing
departure authorizations, and acknowledging
instrument flight rules cancellations or
departwellanding times. As a secondary function, they
can be used for advisory purposes whenever the
aircraft is below the coverage of the primary aidground
frequency
remote control - The control of an object with radio
signals from a remote location.
remote transmitterlreceiver - See remote
communications outlet.
Rene metal - A nickel chromium alloy used in the
manufacturing of gas turbine engines.
repair - To restore an item to a condition of practical
operation or to its original condition.
repairman license - A certificate issued by the FAA to
a person employed by a repair station, a certified
commercial operator, or a certified air carrier required
to provide a continuous airworthiness maintenance
program. The repairman license is valid only as long as
the person holding the license is employed by the
company for which the certificate was issued.
repeater indicator - An instrument that repeats the
information via a master indicator.
repeating decimal - A fraction that cannot be expressed
as a definite number. The fraction '13 is a repeating
decimal (0.333333333).
report - Used to instruct pilots to advise ATC of
specified information; e.g., "Report passing Hamilton
VOR."
reporting point - A geographical location in relation to
the reported position of an aircraft.
repression - A process in which a person
subconsciously forgets or excludes unpleasant or
anxiety producing information.
repression - Theory of forgetting where a person is
more likely to forget information that is unpleasant or
produces anxiety.
repulsion - The force that tends to cause objects to
move away from each other.
repulsion motor - The repulsion motor consists of
stator (field) windings that are powered by input power
and rotor windings that have current induced by the
magnetic field of the stator windings. The rotor
windings are connected to the commutator and the
brushes are connected to each other completing a
circuit through windings within the rotor. The closedloop
circuits in the rotor are effectively the shortcircuited
secondaries of a transformer, where the
motor's field windings are the primary coil. The
currents induced in the rotor create a magnetic field
that repels that of the field winding (Lenz's law). This
repulsion causes the rotor to turn because the brushes
are offset from the field poles, so that the repulsive
forces are pushing on the rotor tangential to the rotation
axis of the rotor. The brushes can be shifted to control
the speed and direction of rotation.
request full route clearance - Used by pilots to request
that the entire route of flight be read verbatim in an
ATC clearance. Such request should be made to
preclude receiving an ATC clearance based on the
original filed flight plan when a filed IFR flight plan
has been revised by the pilot, company, or operations
prior to departure.
required equipment - Equipment determined by the
FAA to be necessary for an aircraft to be considered
airworthy.
required inspection item (RII)- A designation of
items of maintenance and alteration that could result in
a failure, malfunction, or defect endangering the safe
operation of the aircraft if an inspection is not properly
performed or if improper parts or materials are used.
required navigation performance (RNP) - A
statement of the navigational performance necessary
for operation within a defined airspace. The following
terms are commonly associated with RNP:
a. Required Navigation Performance Level or Type
(RNP-X). A value, in nautical miles (NM), from the
intended horizontal position within which an aircraft
would be at least 95-percent of the total flying time.
