Maybe there will be some Lancing going on soon! :}

From an ATC perspective it's not very nice having to thread following traffic through a few delayed early birds - safer to let them through. Ducking & weaving for the sake of enforcing an administrative procedure is increasing complexity & risk unduly.

A threat of a nice hefty fine or a sin binning denial of a slot for a day or two would be my favoured option. Everyone would clean their act up rather rapidly at minimal risk.

A mate said he once delayed his departure time by 1 hour to meet his "PTL" yet still copped 20 minutes enroute delay in a 1 hour leg.

To me it sounds like there must be a lot of "cheating" going on for that to happen?

There is a lot of cheating going on, as was evident if you flew in last night from the north.

Bloggsy! How does 40 tonnes of fuel equal 120,000 kg of CO2 (up in smoke)? Alchemy?

Don't worry FF, did me homework. Burning 1 tonne (or whatever) of Avtur produces 3 tonnes of CO2. :eek:

Example: Aviation sources

Chemistry.......

Hydrocarbon = mainly carbon

Jet A-1 is approximated by C12H26

Atomic weights: H = 1, C = 12, O = 16 (ignoring isotopes)

Molecular weight C12H26 = 12x12 + 26 = 170

Burnt hydrocarbon = CO2 + H2O

Total molecular weight of resulting CO2 = 12x(12 + 16x2) = 528

Ratio of resulting CO2 weight to originating hydrocarbon = 528/170 = 3.1

Burning 40t = 40,000kg of jet A-1 produces

40,000 x 3.1 = 124,000kg CO2.

That's fascinating! So fuel oxidised makes a big mess. Fuel really is a condensed product!!

I wonder if the fact that a little fuel is mixed with a lot of air for combustion, influences the CO2 output? :}

PER - Worst airport in Australia
 

The parlous state of the Perth airport is astounding. The current runway taxiway works are causing chaos and when all is said and done (if they ever get finished) they will not increase the movement rate by even one movement per hour.

Even more astounding is the fact that the government sit back and watch while an essential part of national infrastructure is being so badly mismanaged.

I suspect the mining boom will be over before their planned Terminal WA is completed. More fool on them. In the meantime we suffer together.

It's been discussed on here before but they are suggesting that the airport can expect an significant increase in traffic without the need for a parellel runway.

For some reason no government in this country at any level wants to do anything about aviation............but spending 30 billion on a railway tearing up forrests and farmland is a good idea.:ugh:
