This is a question our experts keep getting from time to time. Now, we have got the complete detailed explanation and answer for everyone, who is interested!
You will need to navigate to the Airports page, search for the airport, navigate to the Protocols sub-tab, select Arrival, and then check for the Alternative minimums line on the page. This will allow you to view the information regarding the non-standard IFR alternate minimums.
How can one determine what the alternative minimum is?
Examining an approach plate provided by the airport is the simplest and most convenient method. There will be a black triangle with a capital letter A inside of it in the remarks area of the government plates. It denotes that there are alternative minimums that are not standard and have been published for that airport. To put it another way, those minimums are not the same as the ones listed in Part 91.
Why do airports have their own alternative minimums that aren’t standard?
The idea of non-standard alternate minimums is to add an additional layer of protection to the overall system. You can identify if an airport or approach has non-standard alternate minimums by searching for an inverted triangle with an “A” in it on the approach plate. There are a number of different reasons why an airport or approach can have these non-standard alternate minimums.
Which official publication of the government would contain the information regarding the alternate minimum?
The section titled “IFR Alternative Minimums” in the FAA U.S. Terminal Procedures Publication (TPP) purports to show the following: Airports within this geographical area that require alternate minimums other than standard or alternate minimums with restrictions are shown below.
What are the alternate minimums that are considered standard?
A ceiling of 600 feet and visibility of two statute miles are required as the standard alternate minimums for a precise approach. The minimal requirements for a non-precision approach are a ceiling of 800 feet and visibility of 2 statute miles. The standard alternate minimums apply unless an airport specifically lists higher alternate minimums for that location.

We found 35 questions connected to this topic.
What exactly is meant by the term “alternative”?
The section of 14 CFR 91.167 that deals with alternatives begins with fuel. It is necessary to have sufficient fuel to fly to the destination, as well as to the alternate, and then continue on for another 45 minutes at the standard cruise speed. Thus, both should be checked during flights lasting less than an hour. According to section 91.169, not just any airport can qualify as an option.
What are the requirements for using an alternative 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 exactly is meant by “delete alternate”?
A take-off alternate is an aerodrome that an aircraft is able to land at in the event that it becomes necessary to land the aircraft quickly after takeoff but it is not possible to utilize the aerodrome that was used for departure.
What exactly does it mean when it says that alternate minimums are not authorized?
NA indicates that alternate minimums are not approved because the facility in question is not monitored, there is no weather reporting service available, or there is insufficient navigation coverage. Civil pilots see FAR 91. … The IFR Alternative Minimums Notes have to be reviewed by pilots in order to determine whether an alternate airfield is suitable.
Is it possible to utilize a GPS method as an alternative?
For airports that have both ground-based navaid IAPs and GPS-based navaid IAPs, the GPS-based navaid IAPs will often show up as NA when submitting as an alternate for the airport. The NOTAM now gives pilots the option of using a GPS-based instrument approach procedure (IAP) at either the destination airport or an alternate airport during flight planning, but not at both locations.
Is RNAV a precise method of navigation?
Non-precision approaches that give lateral guiding are referred to as LNAV approaches. When WAAS equipment is not being used, the pilot is required to verify the RAIM (Receiver Autonomous Integrity Monitoring) system before beginning the approach. For more reference, please see AIM 1-1-19, 5-1-16, and AC 90-105.
What is the key distinction between a precision approach and a non-precision approach?
During a precise approach, a navigation system that guides the aircraft along its track and glidepath is utilized… A non-precision approach makes use of a navigation system to correct for course deviation, but it does not provide information regarding the glidepath. VOR, NDB, and LNAV are all examples of these methods.
What kind of infraction does it constitute if a pilot does not have an instrument rating but yet files a flight plan for IFR conditions?
The submission of an IFR flight plan by a pilot who does not hold an instrument rating is not considered to be in breach of any regulations. Every individual who reads that regulation and comes to the opposite conclusion demonstrates a lack of comprehension of what he has read.
How does the 123 rule work?
Mariner’s 1-2-3 rule, often known as the Danger Rule, is an important set of guidelines that mariners adhere to in order to stay out of the path of a tropical storm or hurricane. It is a reference to the rounded long-term forecast errors provided by the National Hurricane Center (NHC), which are 100-200-300 nautical miles at 24-48-72 hours, respectively.
What are the requirements for takeoff?
Note: as a quick refresher, the usual takeoff minimum visibility requirement for airplanes with one or two engines is one mile, whereas the requirement for airplanes with three or more engines is half a mile. If you are a pilot operating under Part 91, you have the authority to refuse to carry out a SID if you do not choose to.
What are the other weather minimums for precision approach under Part 91 of the Instrument Flight Rules?
Making Plans for Your Alternative IFR
If a useable precision approach is available, then there must be ceilings of 600 feet and visibility of 2 standard meters. If just a method that does not require precision can be implemented: 800 feet and two statute miles of visibility.
What are the weather requirements for IFR flights?
IFR refers to conditions in which the ceiling is less than 1,000 feet above ground level or the visibility is less than three miles. Low IFR, sometimes known as LIFR, is a sub-category that falls under IFR. A ceiling of more than 3,000 feet above ground level (AGL) and visibility of more than five miles are required for VFR conditions.
When is the IFR required to be filed?
Why is an Instrument Flight Rule (IFR) Flight Plan Necessary, and When Do You Need to Submit One? A flight plan is necessary each and every time a pilot wishes to fly in controlled airspace under instrument flight rules, regardless of whether this occurs prior to departure or prior to entering controlled airspace. At the very least, a flight plan for IFR should be filed for submission half an hour before takeoff.
Do helicopters fall under the alternate minimums clause?
Helicopter IFR Alternates
If the weather reports and predictions for the intended destination do not meet certain minimal requirements, the pilot is required to file for an alternate. These minimums are different for operators who fall under Part 91 or Part 135.
If the weather doesn’t meet the basic requirements, can you still shoot an approach?
Even if weather conditions are below minimums, pilots operating their aircraft in accordance with the regulations of FAR Part 91 are permitted to try an instrument approach. As we see in the report for this week’s episode of Probable Cause, however, when talents become stale, it may be time to take a more cautious approach…. The majority of times, these mishaps result in fatalities.
What exactly is meant by “enroute alternate”?
Alternate path en route: An airport that can serve as a backup landing spot for a plane in the event that it is required to make a detour while the plane is on its way to its final destination (it may also serve as the takeoff and/or destination airport).
How much additional fuel must a flight operating under flag rules carry if there is no requirement for an alternate?
In addition to the en route fuel, alternate fuel, and the 10 percent en route reserve fuel, § 121.645(b)(4) requires the airplane to have enough fuel to fly for 30 minutes at holding speed at 1,500 feet above the alternate airport, or the destination airport if no alternate is required by § 121.621(a)(2) or 121.623(b).
When is the required time for listing a takeoff alternate on the dispatch release?
When the meteorological conditions are above the minimums for takeoff, but below the minimums for landing for the departure runway or airport, instrument flight rules takeoff alternates are necessary. Takeoff alternates aren’t required by Part 91, and in most cases, they only apply to air carriers who operate under Part 135 or Part 121.
Can a VFR pilot file IFR?
You are permitted to file a flight plan for IFR flying, but you are not permitted to accept the clearance.
If I’m not up to date, can I still file an IFR?
Yes. If there is an active instrument-rated pilot aboard the aircraft who is not the “sole manipulator of the controls,” then that pilot is eligible to serve as the PIC legally while flying in instrument meteorological conditions. Also, the out-of-date pilot could be brought up to date using this method.
