Dustbin lorries were not removed from instant service across the UK until the inquiry was concluded, why was the Hunter? It's now been explained to you why the Hunter is not in service so perhaps you can be a bit more level headed. The enquiry hasn't been concluded and your attitude seems to be 'I don't care what happened, I like planes, give me what I want, waaaahh'. You say because these things happen very rarely, we should just accept it and move on. Which seems slightly bizarre, aviation didn't get as safe as it is with an attitude like that. It is because of this robust reaction to accidents that incidents are as rare as they are, long may that continue. Even incidents that don't kill people are investigated thoroughly, sometimes planes grounded, and lessons learned implemented. If very bad decisions were made that day, it is very important that they are learned from. If the risk can be reduced it should be, I'm not sure why you're against that. You made a bizarre point about financial implications, it's not a conspiracy you know. Some things are vital to society functioning, some things are not. Society will make the judgement in the end, not you or some conspiracy of bankers out to spoil your fun, and I think society decided air displays are a long way down the list of things it's willing to accept the risk of being killed for. |
That is not what I was inferring, what I was trying to get across is when it is a major item that effects us all and is a necessity, there is often not the same reaction. Far from it, my job entails ensuring safety is paramount, sadly as I mentioned earlier, in some respect, there is a relaxation of the rules, which personally i think is wrong. if you want an example of safety verses economics, read

That is not what I was inferring, what I was trying to get across is when it is a major item that effects us all and is a necessity, there is often not the same reaction. Consider the downside to removing all the garbage trucks from the roads? Public health is the most obvious. Now compare with the downside of cancelling an airshow/restricting it. The latter, we can all get on with our lives without issue, the former would cause some fairly serious issues for the basic functioning of society. And probably a number of deaths from health impacts. It's basic cost benefit analysis. |
Which is exactly what I posted, the Hunter was immediately grounded because no one knew if the jet was the cause, no one knew either if the lorry was at fault either, but it wasn't.
|
NL, fact or assumption? Maybe all their trucks were recalled and checked. Obviously nothing found. Maybe they contacted the manufacturer.

AIUI the basic cause of the Glasgow bin lorry incident was established very early to be driver incapacitation. This was confirmed by a number of witnesses both within and outside the cab of the lorry. The lorry itself was also the subject of an engineering inspection. ITYF a number of public sector HGV/PSV operators have reviewed their procedures in terms of checking driver licenses and medicals.

Just to clarify a small misunderstandng in your display story Glad Rag:
The "vv" IS where the cab is going. That's why pilots use it as a reference. In very high AoA manoeuvres the VV sits at the bottom of the HUD flashing to inform the pilot that the real vector is out of the field of view and cannot be used. So, it's the LFD (and chord line) above the vv (or flight path) in the manoeuvre you describe. |
You misunderstand gr. I wasn't patronising or attempting to patronise you. Just helping by clearing up a small error in your abysmal nomenclature.
...but if you're too arrogant or ignorant to accept such help, then fine. I suggest you go and read AP3456. |
I took my lads to Sunderland airshow today.
The Norwegian Vampires were so far out to sea it was fairly pointless having them there. |
Which is exactly what I posted, the Hunter was immediately grounded because no one knew if the jet was the cause, no one knew either if the lorry was at fault either, but it wasn't. the continuing ban and financial implications on the owners of Hunter aircraft, whose assets are now virtually worthless, even though that wasn't the primary cause of the accident and may have complied with all the legislation and requirements in place. Dustbin lorries were not removed from instant service across the UK until the inquiry was concluded, why was the Hunter? |
All this verbiage about a bin lorry is just a load of garbage. It has no basis of comparison in this instance, except perhaps the prospect of vintage aircraft being binned from future air shows.
|
Come on Nutloose, how many people do you need to tell you that your comparison was fatuous? Bone headed was my choice of words and your subsequent posts have only reinforced that view.
You then said: Far from it, my job entails ensuring safety is paramount... S-D |
Will you two please get a room....!!
:rolleyes: |
Oh dear gr, I seem to have touched a nerve old timer.

Someone take their handbags away!

What does vv stand for? I assumed velocity vector, but velocity is a vector, so I must be wrong again.
|
The term "velocity vector" (vv) refers to a symbol on a display, usually a head-up display, that indicates where the aeroplane is going as opposed to where it's pointing. You can consider it to be the end of an arrow which is aligned with the velocity of the airplane where that velocity hits whatever is in front of it.
If the vv is "painted" on the ground it doesn't matter that your nose is 25 degrees above the horizon - you're going to hit the ground unless you add some energy from somewhere(!). Equally if the VV is holding stable just beyond the piano keys, and t horizontal and vertical velocities are at the preferred values, then you're approach is probably good and you just need to remember to flare [or not, depending on type - consult you owners' handbook].

Thanks, I understand that now, but why the tautology? Velocity is a vector in and of itself (speed in a direction.) Airbus call what you describe the flight path vector (FPV) speed is shown elsewhere.

Velocity (being as you say a vector) has two elements - a magnitude and a direction. When people use the expression "velocity vector" the parameter they're usually talking about is just the "direction" element and the magnitude is not of interest. Whoever the first person was who coined the phrase to name a symbol on a display decided that "Velocity Vector" was a good name for the parameter "the direction the speed is travelling in". Aviation, like so many other fields, has terms evolved through usage which no longer make literal sense. Life's like that. In fact ironically the term "tautology" itself is another example, but that's for another thread. PDR |
