Here’s another chance to test your “AVsavvy”.

Suppose a captain is in the process of creating a flight plan from LFPB to KHPN. He has determined that he will utilize F/L 430.

The following are excerpts from the AIM:
Terminal Aerodrome Forecast (TAF) and
their amendments (AMEND) − Text report − Routine
forecast that gives a concise statement of expected
meteorological conditions for a specified time period
within five statute miles (SM) of the center of the
airport’s runway complex (terminal). TAFs are
amended whenever they become, in the forecaster’s
judgment, unrepresentative of existing or expected
conditions, particularly regarding those elements and
events significant to aircraft and airports. An
amended forecast is identified by TAF AMD (in place
of TAF) on the first line of the forecast text.

1. TIS−B is intended to provide ADS−B
equipped aircraft with a more complete traffic picture
in situations where not all nearby aircraft are
equipped with ADS−B Out. This advisory−only
application is intended to enhance a pilot’s visual
acquisition of other traffic.
2. Only transponder−equipped targets
(i.e., Mode A/C or Mode S transponders) are
transmitted through the ATC ground system
architecture. Current radar siting may result in
limited radar surveillance coverage at lower
altitudes near some airports, with subsequently
limited TIS−B service volume coverage. If there is
no radar coverage in a given area, then there will be
no TIS−B coverage in that area.

Altitude assignments for direction of flight follow a
scheme of odd altitude assignment for magnetic
courses 000−179 degrees and even altitudes for
magnetic courses 180−359 degrees for flights up to
and including FL 410.

TIS operation may be intermittent during turns or other maneuvering,
particularly if the transponder system does not
include antenna diversity (antenna mounted on the
top and bottom of the aircraft). As in (d) above, TIS
is dependent on two−way, “line of sight” communications
between the aircraft and the Mode S radar.
Whenever the structure of the client aircraft comes
between the transponder antenna (usually located on
the underside of the aircraft) and the ground−based
radar antenna, the signal may be temporarily
interrupted.

Based on the above information, which statement below is correct? Answer below and come back next Friday to see if you got the answer right!
