what is TX in a metar or TAF
found this question somewhere...

Mercenary Pilot 26th Nov 2007 21:24

I think TX is maximum temp, and TN is minimum temp forecast. :8

HeliCraig 26th Nov 2007 21:27

Never seen it actually used (at least in the UK), but it is Max Temp.

This page is always good: http://aviation.weathersa.co.za/codesexpl.php

Not in the abbreviations list on the Met office site. I shall pen it in on my copy.

Not sure if these links will work. You need a login (it is free)

Hi all,

I came across this one a few days ago, although it's todays, what does the RS0109KT 050209KT 230109KT Stand for?

LPMA 270000Z 03009G20KT 350V070 9999 SCT018 19/12 Q1023 RS0109KT 050209KT 230109KT
LPMA 262300Z 270009 03010KT 9999 SCT018
TEMPO 0009 03012G22KT SCT018 BKN030

These are some points were they are reporting the Winds. RS stands for Rosario.

Bus14 27th Nov 2007 10:34

LPMA is Funchal/Madeira. RS (Rosario) is about a mile short of the 05 threshold and sits at the end of a valley down which winds blow which can cause all sorts of chaos on short finals. 05 is the touch down anemometer for RWY05 and 23 is the same for RWY23. The main wind is the tower wind. The Portugese AIP has the detailed rules on the limits that apply for take-off and landing.

Although the runway is now quite long, LPMA remains one of the more challenging/fun airports to visit. Just think of it as an aircraft carrier moored alongside a big cliff and you get the idea:cool:.

Interesting. Thanks! :ok:

ATPL Air Law ICAO Articles & Annexes
Not that I'm work-shy, you understand......but is one expected to remember each of the Chicago Convention's articles & annexes, what each refers to and their implications?

And I thought the FREDA thing was tough!! :ooh:

Whirlygig 17th Aug 2009 17:45

You might one, maybe two if you're unlucky, questions asking which Annex number deals with .... whatever.

However, you are expected to know the contents and their implications (if not the number).

Thanks for that guys!

Air1980 18th Aug 2009 00:28

Any other memory aids? Like for example the chart specifications (Lambert etc)?

PintofT 18th Aug 2009 00:45

Air1980, PM sent. May be of help.

Mohit_C 18th Aug 2009 08:56

greekboy one correction. The DALR is 3C/1000ft OR 1C/100m.

Instrumentation (atpl questions)
Hi all,

Here are a few questions from oxford school regarding instrumenation which, actually, are not that hard but i prefer to ask for advise before submitting my assessment.
So enjoy it !

1) With a fully equipped FMS aircraft the following selections are usually utilised in flight :
a- LNAV only
b- LNAV and VNAV
c- VNAV only
d- LNAV and VNAV but not simultaneously

I'd answer d), cause if i have well understood lnav is used during cruise while vnav is more concerned with climb&descent, so the use of both modes cannot be simultaneous. Is that right?

2) If the radio altimeter fails :
a- height information disappears
b- aural warning given
c- radio alt flag, red lamp, and aural warning given
d- radio alt flag and red lamp activates

I'm quite hesitating between c) and d).

3) If an aircraft fitted with two FMSs, the pilots' displays show contradictory information. What mode of FMS is in use?
a- independant mode
b- dual mode
c- single mode
d- separate mode

Answer a) ?

Thanks guys!

_ShIfTy_ 31st Dec 2009 19:00

I would go with answer B to the first question. L-NAV and V-NAV are both used during most part of the flight.
