No, if you are using the advertised runway and there is only one runway in use, then no, the controller does not have to tell you which runway to enter your base on. He is expecting you to do that on the advertised runway (if it is not the advertised runway, that is a different ballgame). Also, in your landing clearance, the controller does not have to state the runway number if it is on the advertised runway, and there is only one advertised runway. Now, I'm not saying that the controller should not do that, and it might not be a good practice, but it isn't required. Depending on how busy the controller is, a good controller learns which elements are extra, and not required, and might omit them, to save frequency congestion. Again, I'm not advocating it, but the controller does not have to give the runway. This is straight out of the 7110.65, so if something happens, I can't see how it would bite the controller in the ass, since he did everything "by the book". Again, though, I don't think ever have omitted the runway number, I'm just saying it is not required in all cases.
3-10-1. LANDING INFORMATION
Provide current landing information, as appropriate,
to arriving aircraft. Landing information contained in
the ATIS broadcast may be omitted if the pilot states
the appropriate ATIS code. Runway, wind, and
altimeter may be omitted if a pilot uses the phrase
“have numbers.” Issue landing information by
including the following:
NOTE
Pilot
use of “have numbers” does not indicate receipt of the
ATIS broadcast.
a.
Specific traffic pattern information (may be
omitted if the aircraft is to circle the airport to the left).
PHRASEOLOGY
ENTER
LEFT/RIGHT BASE.
STRAIGHT-IN.
MAKE STRAIGHT-IN.
STRAIGHT-IN APPROVED.
RIGHT TRAFFIC.
MAKE RIGHT TRAFFIC.
RIGHT TRAFFIC APPROVED. CONTINUE.
b.
Runway in use.
c.
Surface wind.
d.
Altimeter setting.
REFERENCE
FAAO
JO 7110.65, Para 2-7-1, Current Settings.
e.
Any supplementary information.
f.
Clearance to land.
g.
Requests for additional position reports. Use
prominent geographical fixes which can be easily
recognized from the air, preferably those depicted on
sectional charts. This does not preclude the use of the
legs of the traffic pattern as reporting points.
NOTE
At
some locations, VFR checkpoints are depicted on
sectional aeronautical and terminal area charts. In
selecting geographical fixes, depicted VFR checkpoints
are preferred unless the pilot exhibits a familiarity with the
local area.
h.
Ceiling and visibility if either is below basic
VFR minima.
i.
Low level wind shear or microburst advisories
when available.
REFERENCE
FAAO
JO 7110.65, Para3-1-8, Low Level Wind Shear/Microburst
Advisories.
j.
Issue braking action for the runway in use as
received from pilots or the airport management when
Braking Action Advisories are in effect.
REFERENCE
FAAO
JO 7110.65, Para 3-3-5, Braking Action Advisories.
3-10-5. LANDING CLEARANCE
a.
Issue landing clearance. Restate the landing
runway whenever more than one runway is active, or
an instrument approach is being conducted to a closed
runway.
PHRASEOLOGY
CLEARED
TO LAND,
or
RUNWAY (designator) CLEARED TO LAND.
b.
Do not clear an aircraft for a full-stop,
touch-and-go, stop-and-go, option, or unrestricted
low approach when a departing aircraft has been
instructed to taxi into position and hold, is taxiing into
position, or is holding in position on the same runway.
The landing clearance may be issued once the aircraft
in position has started takeoff roll.
c.
“USN NOT APPLICABLE.” Inform the closest
aircraft that is requesting a full-stop, touch-and-go,
stop-and-go, option, or unrestricted low approaches
when there is traffic authorized to taxi into position
and hold on the same runway.
EXAMPLE-
“Delta One, continue, traffic holding in position.”
or
“Delta One, runway one eight, continue, traffic holding in
position.”
d.
During same runway operations, while TIPH is
being applied, landing clearance must be withheld if
the safety logic system to that runway is inoperative
or in limited configuration or conditions are less than
reported ceiling 800 feet or visibility less than
2miles.
EXAMPLE
If
the safety logic system is operating in full core alert
runway configuration:
“Delta One, cleared to land. Traffic holding in position.”
or
“Delta One, runway one eight, cleared to land. Traffic
holding in position.”
e.
USA/USN. Issue surface wind when clearing an
aircraft to land, touch‐and‐go, stop‐and‐go, low
approach, or the option. Restate the landing runway
whenever there is a possibility of a conflict with
another aircraft which is using or is planning to use
another runway.
PHRASEOLOGY
WIND
(surface wind direction and velocity), CLEARED
TO LAND,
or
WIND (surface wind direction and velocity), RUNWAY
(designator) CLEARED TO LAND.
NOTE
A
clearance to land means that appropriate separation on
the landing runway will be ensured. A landing clearance
does not relieve the pilot from compliance with any
previously issued restriction.
