Is Mesa cat II certified?

[ackattacker]

Not really.

You don't list is your legal alternate..you just change your destination if the wx is legal for an approach when you get close to it.

Example: KTEX is a popular "change of destination" from KMTJ if you're flying an aircraft of Cat C min approach speed and the weather at arrival cooperates.

Rettofly, you must be talking private jets.

That kind of thing doesn't fly in the airline world. They do something similar with re-dispatch enroute to save fuel on some flag routes, but never to launch for a destination that's illegal due to weather. I think the FAA would come down on that hard. Your real destination isn't exactly a closely held secret in the world of scheduled airlines.

Curious on what carriers run their operations like this??

It is not legal to dispatch that way in the 121 world.

Might be the training cost.... How many CATII's do you shoot a year on the east coast?

2 in the last week.

2 in the last week.

Well 2 in one week might be all you've done all year. I've diverted once this year and once last year because of our CAT 1 limits. And I flew a ton.

Doesn't matter what the current RVR is until you get to the FAF. If the TAF says 1/4 then they can't even launch.

Its possible using the RVR rule(which isnt technically a rule I guess), but the flight has to be under an hour in length. At least we can use this at XJT. I have never used it, but it is an option.

The reasoning for this rule, as I understand it, is because of the location of the sensors. The sensors for the METAR/TAF could be on the tower, which could be in the fog/clouds/whatever is causing the low vis to be reported. However the RVR sensors are, obviously, on the runway which could be reporting 6000RVR.

Got to call the tower, get the RVR, get their opinion(since, in theory, they know the way weather behaves at their airport) on whether the low vis will continue, get better, get worse, etc...

It's 100% LEGAL. Smart- no.

There is no rule that says that you can't change your destination enroute (as long as the airport to which you are changing to is listed in ops specs C070)... as long as you have the fuel to fly to the destination thence fly to the farthest alternate listed.

I think if I was scheduled on flight xxxx to airport A, I wouldn't accept a release to airport B. In 121 I don't think that would be legal unless it was a planned fuel stop situation.

 

[propsarebest]

You are still going to A... just a different A.

I would hope and pray I never have you as a dispatcher with that logic

 

[propsarebest]

you have no idea WTF you are talking about. CHANGING YOUR DESTINATION FOR ANY REASON WHILE ENROUTE IS 100% LEGAL.PERIOD.

A 121 carrier cannot dispatch an aircraft to a destination if at the ETA the weather is below landing minimums (domestic operations). So an airline with OpSpec approval for CATIIIB operations and if the airport is certified to conduct these operations. The weather could be as low as 300 ft RVR.

There a few ways around the weather requirement. The airline could file using exception 3585 or use EWINS. Both work for domestic operations

For Flag operations the airline may dispatch the flight, if the weather at the destination is below landing minimums. Except for the airports were no alternate is required (over water operations). When flying to a city like Sydney, Australia. Which does not require an alternate. When the forecast shows the weather as below landing minimums. The airline will dispatch the flight to Melbourne. When closer to the destination (12 hours later) if the weather is at or above landing minimums the destination is changed to Sydney. Everybody wins and the passengers have no idea.

That's not what they're talking about. Read the posts again.

Let's get on the same sheet of music here...You are making a fool of yourself

 

[propsarebest]

nope.

 

[moonship]

3585 would only work if the below min's visibility is a conditional remark. 1/4 sm in the main body is no go for CAT1.

Take your pick.

The issue at KTEX is that the published procedures are limited to Approach Cat A and B aircraft. Weather could be (and usually was) above IFR mins but less than 1500 ft above lowest MEA.

The Regional that operates into KTEX uses Approach Cat B aircraft; it's not an issue for them.

Who's the carrier that serves KTEX?

 

[surplus1]

If I'm not mistaken KTEX is Telluride. This is a high elevation (9K ft) general aviation airport which I think is served by a company called Great Lakes operating the Beech 1900, which isn't even an airliner. I could be wrong but I don't think any real airliner can even go to that airport, regardless of the wx (unless they fly empty).
