What are the minimum weather conditions that must be forecast to list an airport as an alternate when the airport has no approved IAP?
The ceiling and visibility at ETA must allow descent from MEA, approach, and landing, under basic VFR.
Under what weather conditions are you required to list an alternate airport in your IFR flight plan?
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 are the alternate minimums for an airport?
So, what are alternate minimums when flying IFR? 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 are the alternate minimums for an airport with a precision approach procedure?
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 minimum weather conditions must be forecast for your ETA at an alternate airport that has only a VOR approach with standard alternate minimums for the airport to be listed as an alternate on the IFR flight plan?
then to the alternate airport, and then for 45 minutes at normal cruising speed. When an alternate airport is required, what are the weather minimums that must be forecast at the ETA for an alternate airport that has a precision approach procedure?
600 foot ceiling and 2 statute miles visibility.
What alternate weather minima must be forecast for your ETA at an airport that has two or more precision approach procedures?
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.
Where can alternate minimums be found?
The airport’s alternate minimums, standard or nonstandard, are listed
on the airport’s 10-9 page
. If you’re able to use the ILS to runway 7 at KDAB, your alternate minimum weather can be as low as 700′ ceilings and 2 SM visibility.
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.
Do alternate minimums apply to helicopters?
Helicopter IFR Alternates
The pilot
must file for an alternate if weather reports and forecasts at the proposed destination do not meet certain minimums
. These minimums differ for Part 91 and Part 135 operators.
When must you file IFR?
When Is an IFR Flight Plan Required and When Must You File One? Every time a pilot wants to fly in controlled airspace under IFR, whether that is prior to departure or prior to entering controlled airspace, a flight plan is required. An IFR flight plan should be submitted
at least 30 minutes before departure
.
What are the IFR minimums?
IFR means a
ceiling less than 1,000 feet AGL and/or visibility less than three miles
. Low IFR (LIFR) is a sub-category of IFR. VFR means a ceiling greater than 3,000 feet AGL and visibility greater than five miles.
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 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 an airport that only has a GPS be filed as an alternate?
According to the new policy, which will be added to future versions of the AIM, advisory circulars, and other documents, pilots with non-WAAS GPS navigators can now file an
alternate airport
that is served only by GPS-based instrument approaches, provided the original destination airport has ground-based procedures, or …
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.
What are the basic VFR minimums?
Basic VFR Weather Minimums
cloud
ceiling at least 1,000 feet AGL
; and. ground visibility at least 3 statute miles (usually measured by ATC but, if not available, flight visibility at least 3 statute miles as estimated by the pilot).
