Wind Limits Funchal
 

In an unusually windy winter/spring there have been a great many diversions from LPMA. I read that the quite restrictive wind limits are under review by the portuguese authorities. It's said these limits date back to the 1960s, long before the impressive runway extension on stilts was constructed and before the current generation of aircraft were even on the drawing board. I never had the pleasure of operating through FNC but have visited many times as SLF. There's no doubt that the topography produces considerable turbulence when the wind is in the north west quarter so I wonder how those of you who do operate there regularly would view an easing of current restrictions. (Put rather
simply approaches to 05 are not allowed when the wind is 300 through 010 and above 15 gusting 25.)

The current limitations seem eminently sensible to me as Funchal is one of those you treat with huge amounts of respect. Sticking in that neck of the woods, Porto Santo, Flores and Horta can also bite. Further North, Gibraltar is just plain nasty.

I've been into FNC several times with the wind near limits. I'd like to keep the limits :eek:

I only did the qualifying sim-training, never rostered to operate. A lot of the sim time is made up of various wind-shear events and recoveries. Not a nice place.

Normally the wind displayed on the HSI at 50' RA is considerable different from what you have been given.

A colleague from way back was landing there one morning, within limits, when, in the final stage of the flare, a sudden gust from right behind put him firmly on the nose wheel with resultant damage to the aircraft. Even when observing all the limits Funchal can still get up and bite.

Had several days in the last year with TAF's suggesting light North Westerlies and fine conditions, only to find the 05 TDZ wind brushing up against the 15kt limit. A 7kt forecast to a 15kt actual is not a huge increase.

I'd rather keep the limits too - And that's absolutely nothing to do with the significantly increased possibility of a leisurely evening somewhere in Portugal or Canaries, which is otherwise a rarity for us! :p

Fun flying when the weather was nice but I've not seen the extensions. I'm mindful such structures could be the generators of curly air in their own right.

Miss flights like that. Put one on one's metal - whatever that means. :ooh: Oops, Mettle. Thanks Chris2303

Mettle
ˈmɛt(ə)l/

The wind there doesn’t even need to be near limits for go arounds and diversions.
It all depends on the direction, turbulence and drift.

Jo 90 : You have the reference to that ? the limits are not there to restrict operations but to ensure safety . I hope someone in an office understood that bit .

Which in turn is considerably different from what is actually happening.
It's one of the things that grinds my gears.
FMC derived wind might be useful for giving others spot winds in the cruise.
At a push for sussing out possible tailwind on finals, (stressing the possible).
After that it is historical information.

In my ignorance I thought that landing limitations are decided by the airlines, not ATC or any other ground authorities. Genuine query, I am confused

There's a report, but I haven't enough posts to attach it, being an interested SLF lurker who doesn't usually feel informed enough about anything, to post!!
Add www to the start of this and you should get there !!

I understand that the Committee on Economy, Finance and Tourism Madeira of the Legislative Assembly of Madeira are holding inquiry into the operation of the airport, and this is a report of evidence it received from an experienced pilot, suggesting that the mandatory limits be removed, and the onus placed on pilots to make their own judgement. Dont know when a decision is expected or even if one will ever be made !!

Here's a quote from a Madeiran news blog:

WIND LIMITS REMAIN FOR SAFETY AT MADEIRA AIRPORT

NEWS STORY
6 COMMENTS3257 VIEWS 5The vice president of the Regional Government today addressed the issue related to the wind limits at the Madeira International Airport Cristiano Ronaldo, which motivated a meeting yesterday in Lisbon, but safeguarded that this is a matter that has to do, mainly, with the security.

Pedro Calado reminds us that the situation of the winds and the operationality of the Airport refers to “a technical issue, very complicated. It is important that we have the notion that it is security. The entity that manages the Airport is ANAC and all decisions have to be authorized by that entity. ANA manages the airports and is in tune with the ANAC “.

Calado says that “what is happening at Madeira Airport is unusual, it is the only airport in the world that has mandatory limits, meaning that even if the commanders consider having safety conditions to land, if the wind limits are above stipulated, can not do so under penalty of ANAC suspending its license to fly. ”

The Vice President of the Government expressed to ANAC his amazement at the fact that the limits set for Madeira Airport have not been changed since 1964, since the inauguration, and the track has already grown, the areonaves are more evolved and the pilots more training, emphasizing that the Regional Government requested the intervention of these entities with jurisdiction in the matter in the sense that the limits are changed from mandatory to recommendable simply because there is not a single airport in the world with this classification.

Pedro Calado also refers to the existence of devices that could eventually provide the Airport with better means, and the Regional Government has shown availability for these acquisitions. What happens is that, even with these acquisitions, ANAC guarantees that there are no conditions today to raise these limits of the winds in terms of safety, since there are contradictory positions regarding the times of measurement of the winds and their conclusions . There is a work that is being developed by several entities and what the Regional Government has requested is that there be speed of studies, always taking into account the safety of people. ”



Relax guys and gals!

".....and the track has already grown, the areonaves are more evolved and the pilots more training, emphasizing that the Regional Government requested the intervention of these entities with jurisdiction in the matter in the sense that the limits are changed from mandatory to recommendable simply because there is not a single airport in the world with this classification."

Are the limits at GIB recommended or mandatory? There are certainly airports in the world that have more restricting tailwind limits than for the a/c. Considering 'pilots have more training'....Hm. There are many threads on here that debate the opposite. I think with the dilution of sharp end experience, and considering where the diversions are, there are is a strong case for some limitations that remove discretion. The length of the runway, for short-haul a/c doesn't remove rotor and threshold turbulence. Red herring. Back in my days of going there in 80's, for us, it was daytime only. TAP went day/night. Perhaps they were considered more 'local' or moe macho; we were never told. It is a special place and needs respect, not machoism.
