Standard alternate minimums for a precision approach are
a 600-foot ceiling and 2 SM visibility
. For a non-precision approach, the minimums are an 800-foot ceiling and 2 SM visibility. Standard alternate minimums apply unless higher alternate minimums are listed for an airport.
What are standard alternate minimums IFR?
The standard minimum weather requirement for an alternate is
600-2 if there’s a precision approach available
and an 800-2 for a non-precision approach. (Note that the visibility requirement is the same.
What are standard alternate minimums?
Standard alternate minimums require the forecasted conditions at the time of arrival be
at least 2 miles visibility
and at or above 600 foot ceilings for precision approaches, or 800 foot ceilings for non-precision approaches.
What is an alternate minima?
For flight by aeroplanes under VFR (day or night) and helicopters operating under VFR at night, the alternate minima are
a ceiling of 1500 ft and a visibility of 8 km
(AIP ENR 1.1). … cloud – more than SCT below a ceiling of 1000 ft, or. visibility – less than 3000 m.
How do you find the alternate minimum?
To view the non-standard IFR alternate minimums information, you will need to go
to the Airports page > search for the airport > on the Procedures sub-tab, tap on Arrival > and then look for
the Alternate minimums line. If there is an entry, tap on it and swipe through the pages until you find the airport in question.
What determines if you need an alternate airport?
You need to name an alternate airport on your IFR flight plan if, for the period of time one hour before and one hour after your estimated time of arrival,
the weather is forecast to include a ceiling of 2,000 feet agl and/or visibilities less than three statute miles
(the 1-2-3 rule).
What is a take off alternate?
A Take-off alternate is
an aerodrome at which an aircraft would be able to land should this become necessary shortly after take-off
and it is not possible to use the aerodrome of departure.
What are the standard alternate minimums of the alternate has one RNAV approach?
Standard alternate minimums for non-precision approaches and approaches with vertical guidance [NDB, VOR, LOC, TACAN, LDA, SDF, VOR/DME, ASR, RNAV (GPS) or RNAV (RNP)] are
800-2
. Standard alternate minimums for precision approaches (ILS, PAR, or GLS) are 600-2.
Can you shoot an approach if weather is below minimums?
Pilots flying under the rules of FAR Part 91 are allowed to attempt an instrument approach even when the weather is below minimums
. But when skills are rusty, it may be time to be more conservative, as we see in this week’s Probable Cause report.
What are takeoff minimums?
Note: a quick reminder, standard takeoff minimums for one and two engine airplanes is
1-mile visibility and a 1/2 mile visibility for 3-4 engine airplanes
. You have the right to decline a SID as a Part 91 pilot if you don’t want to do it.
What is the 123 rule?
The Mariner’s 1-2-3 rule, also referred to as the Danger Rule, is an important guideline mariners follow to keep out of a tropical storm or hurricane’s path. It refers to the
rounded long-term National Hurricane Center (NHC) forecast errors of 100-200-300 nautical miles at 24-48-72 hours
, respectively.
What is the maximum airspeed in Class D airspace?
Unless otherwise authorized or required by ATC, no person may operate an aircraft at or below 2,500′ AGL within 4 NM of the primary airport of a Class D airspace area at an indicated airspeed of more than
200 knots (230 mph)
Is RNAV a precision approach?
LNAV approaches are
non-precision approaches
that provide lateral guidance. The pilot must check RAIM (Receiver Autonomous Integrity Monitoring) prior to the approach when not using WAAS equipment. See AIM 1-1-19, 5-1-16, and AC 90-105.
Can a GPS approach be used as an alternate?
The point of the special rules using GPS as an alternate has to do with the fact that non-WAAS GPS is supplementary navigation. So you can file with the destination or the alternate having only a GPS approach,
but not both
. WAAS-equipped aircraft can file for destinations and alternates having only GPS approaches.
What are approach minimums?
Published Approach Minimums:
Approach minimums are published for different aircraft categories and consist of a
minimum altitude (DA, DH, MDA) and required visibility
. These minimums are determined by applying the appropriate TERPS criteria.
What does the T mean on an approach plate?
When a “T” in a black triangle appears in the notes section of the instrument approach chart, it signifies the airport has
IFR takeoff minimums and/or departure procedures published in Section L of the TPP
.
