Class E weather minima

[rotorspeed]

[*] I was asked. question on pilot exams on weather minima class E vfr with an MF. Answer was 3sm. I thought only control zones had 3 sm. An example would be Nanaimo with has an mf (Nanaimo rafio) which im guessing is class e. I was told minima is 1sm visibility 2000 horizontal and 500 sbove below. Same as uncontrolled.

You are going to have trouble learning what you need to know to fly planes if your source is "I was told". Where have you looked for the answer to your question so far? CARs part VI? AIM RAC?

[rotorspeed]

Chief flight instructor. So what's the answer tc says other control zones 3mi. Is class e with control zone considered other. Such as nanaimo. Where there is an mf

Definitely not 1SM, whether it's considered "control zone" or "other controlled airspace". Both are 3SM.

After a while you learn that CFIs don't always have all the correct answers, and neither does TC either.

Class E is controlled airspace, so controlled airspace minima apply.
3sm flight visibility, and 1sm horizontal or 500’ vertical separation from cloud.

However class E airspace doesn’t extend down to the surface except in a class E control zone. Typically class E airspace ends at 700 or 2200 agl or higher. At an aerodrome underneath class E airspace uncontrolled airspace minima would apply.

If ithere is a control zone (not if it’s an MF area only) two additional VFR minima restrictions apply too:
You must maintain at least 500agl except when taking off or landing, and ground visibility, if reported, must be 3sm or greater.

[rotorspeed]

So would Nanaimo would be 3sm,? I'm a bit confused

[rotorspeed]

If it's not a airport control zone it's only ifr controlled

[JasonE]

I wouldn't fly uncontrolled at less than 3sm anyways!

[rotorspeed]

Still haven't really gotten the answer. Nanaimo is perfect example class E mf in affect. Nanaimo radio

If you can’t work it out, you might want to reconsider the pilot thing.

Go @#$! yourself

Easy now... It's all in there....

2.7.3 Control Zones

Control zones are designated around certain aerodromes to
keep IFR aircraft within controlled airspace during approaches
and to facilitate the control of VFR and IFR traffic.
Control zones having a civil control tower within a terminal
control area normally have a 7-NM radius. Others have a
5-NM radius, with the exception of a few which have a 3-NM
radius. Control zones are capped at 3 000 feet AAE unless
otherwise specified. Military control zones usually have a
10-NM radius and are capped at 6 000 feet AAE. All control
zones are depicted on VFR aeronautical charts and the
Enroute Low Altitude Charts. Control zones will be classified
as “B”, “C”, “D” or “E” depending on the classification of the
surrounding airspace.
The VFR weather minima for control zones are outlined in
Table 2.2. When weather conditions are below VFR minima,
a pilot operating VFR may request special VFR (SVFR)
authorization in order to enter the control zone. This
authorization is normally obtained through the local tower or
FSS, and must be obtained before SVFR is attempted within
a control zone. ATC will issue an SVFR authorization, traffic
and weather conditions permitting, only upon a request for
SVFR from a pilot. SVFR will not be initiated by ATS. Once
having received SVFR authorization, the pilot continues to
remain responsible for avoiding other aircraft and weather
conditions beyond the pilot’s own flight capabilities and the
capabilities of the aircraft.

NOTES:
1. Notwithstanding CAR 602.115, an aircraft other than an
helicopter may be operated in visibilities less than 2 miles
during the day, when authorized to do so in an air operator
certificate or in a private operator certificate.
2. Notwithstanding CAR 602.115, a helicopter may be
operated in visibilities less than 1 mile during the day,
when authorized to do so in an air operator certificate or in
a flight training unit operator certificate helicopter.
Special VFR weather minimum and requirements applicable
within control zones are found in CAR 602.117, and are
summarized as follows:
Where authorization is obtained from the appropriate ATC
unit, a pilot-in-command may operate an aircraft within a
control zone, in IFR weather conditions without compliance
with the IFR, where flight visibility and, when reported,
ground visibility are not less than:
(a) 1 mile for aircraft other than helicopters; and
(b) 1/2 mile for helicopters.
NOTES:
1. All aircraft, including helicopters, must be equipped with
a radio capable of communicating with the ATC unit and
must comply with all conditions issued by the ATC unit as
part of the SVFR authorization.


2.8.5 Class E Airspace
Class E airspace is designated where an operational need exists
for controlled airspace but does not meet the requirements for
Class A, B, C, or D.

Operations may be conducted under IFR or VFR. ATC
separation is provided only to aircraft operating under IFR.
There are no special requirements for VFR.
Aircraft are required to be equipped with a transponder and
automatic pressure altitude equipment to operate in Class E
airspace that is specified as transponder airspace.
Low level airways, control area extensions, transition areas,
or control zones established without an operating control
tower may be classified as Class E airspace.

Maybe you are confused because YCD for example doesn't control VFR traffic, however it is still a control zone. You have to request and be granted SVFR is you want to enter with 1sm visibility.

[rotorspeed]

First off thanks altiplano for the help. Yes I asked a cfi at the school and they told me since there is no tower with a control zone such as cycd, control zone weather minima such as 3sm doesn't apply.By the rules I thought it did as you have stated. Thanks

[altiplano]

No problem.

Good luck.
