I have posted the PACOTS Tutorial several times ago. Thanks to Mr. Adhika Lee who have made these tutorial. Now Lets try to fly it. I will write this in a very simple way without any images.

How to enter the PACOTS coordinate to Airbus FMGC?
Okay, I will use the old PACOTS Route that I’ve used for my flight from VHHH to PHNL. The Routes are:

OCEAN V2 ELATO A1 APU G587 ROBIN R583 LEKOS M750 MJE PETAL OTR14 ACQUA OTR15 MORAY 36N150E 36N160E 28N170E 25N180E 22N170W HOOPA KATHS OPACA

I assume that you have already know and set your FMGC with the active runway and the departure (SID). The steps is very simple. Check it out:

  • You will depart from VHHH Hongkong and follow the route as usual.
  • Now mark this: You will exit your usual route at MORAY. Now…click at MORAY on your Left side FMGC keys.
  • The first PACOTS route is 36N150E. Now type on the scratchpad 360000N/1500000E (Enter the number and add four zeroes behind it) and enter this to “NEXT WPT” on the Right key. Done!
  • You will see LL01 as your first PACOTS fix below MORAY intersection on F-PLAN page.

Next you can proceed by yourself by entering next PACOTS fix in the same way. And you will see LL02, LL03, and so on and so on… for the next PACOTS fix that you’ve made. After you reach the end of these PACOTS route you can enter HOOPA KATHS and OPACA. Just enter them directly without Airways. HOOPA is your entry at Honolulu airspace, and from here you can resume by your own navigation captain and happy landing at Honolulu Airport!

I hope you can understand with my simple tutorial. Any Question please write on the comments field.

How to Read METAR Information

Filed Under (ATC Operations, Flight Operations) by steven on 09-09-2009

METAR or MÉTéorologique Aviation Régulière or Aviation Rutin Weather Report is format for weather reporting. METAR is used by the pilots to know the weather conditions, winds conditions at an aerodrome where they will conduct the flights. Raw METAR is a very known format in aviation for weather data transmision. It’s also an ICAO standard.

METAR reports typically come from airports or permanent weather observation stations. Usually METAR is generated once an hour if there is no significant weather changes.

How to read it?

I’m gonna use several METAR report for example.

WSSS 090730Z 21009KT 170V260 9000 FEW020TCU BKN300 32/25 Q1008 NOSIG

Okay, WSSS, Changi airport – Singapore.

090730Z = METAR was made at 09 (date), 0730Z (time)

21009KT = Wind from 210 degree at 09 knots (wind’s speed)

170V260 = indicates the wind direction is varying from 170° through 210°  to 260°

9000 = indicates the visibility is 9000 meters

FEW020TCU = Few clouds at 2000 feet, TCU is Towering Cumulus (Cumulus cloud that have potential to become into a cumulonimbus within a short time period)

BKN300 = indicates broken cloud at 30,000 feet

32/25 = temperature is 32 degree and dewpoint is 25 degree

Q1008 = QNH or altimeter setting is 1008

NOSIG = No significant changes

Next is

LBBG 041600Z 12003MPS 310V290 1400 R04/P1500N R22/P1500U +SN BKN022 OVC050 M04/M07 Q1020 NOSIG 9949//91

The rest is same as above, Let’s discuss the bold letters only.

12003 = wind from 120 degree with speed at 03 Meter per Second

R04/P1500N = Runway Visual Range (RVR) at Runway 04 is 1500 meters with no significant changes

R22/P1500U = Runway Visual Range (RVR) at Runway 22 is 1500 meters and rising

+SN = Snow falling at heavy intensity

OVC050 = Overcast at 5000 feet

M04/M07 = Temperature is -04°C and dewpoint is -07°C

9949//91 =

  • indicates either a specific runway (eg. “25″=Rwy 25 or “25R”; “75″=Rwy 25L – adding 50 will indicate Left Runway) or all the airport’s runways (”99″)
  • “4″ means the runway is coated with dry snow
  • “9″ means 51 to 100% of the runway are covered
  • // means the thickness of the coating was either not measurable or not affecting usage of the runway
  • “91″ means the braking index is bad, in other words the tires have bad grip on the runway.

Note: For North America use Altimeter or code “A” in their altimeter setting (eg. “A3006″)

Other METAR Codes:

  • CB = Cumulonimbus cloud
  • TSRA = Thunderstorm, Rain at the area
  • BECMG = Becoming
  • CAVOK = Ceiling And Visibility OK
