Probably the bigger issue is that it kills catalytic convertersI think lead was banned because of it's impact on yooman health, but it wasn't too bad for the wider environment.
Being heavy, it didn't get far from roads before falling to earth.
The studies that led to lead being removed from petrol in Britain, were done on primary school kids in schools that were almost underneath the M4 flyover in West London. Unsurprisingly, high concentrations of lead were found in the kids.
That wouldn't surprise me. High performance engines, with very little tolerance of unreliability.TEL is still used in avgas, i believe
I'm sure they would use other widely available additives if it was 'better'That wouldn't surprise me. High performance engines, with very little tolerance of unreliability.
Could be a cost issue, planes burn a lot of fuel, and lead is cheap.I'm sure they would use other widely available additives if it was 'better'
wow, i thought the fuel was cheap.. maybe it is commercially when you're buying millions of gallons, but small amount of jet fuel £1/L and avgas £2/LCould be a cost issue, planes burn a lot of fuel, and lead is cheap.
I don't think either of them are taxed, so if tax was added, that would actually be very expensive indeed, and planes burn a lot of fuel, especially on take off.wow, i thought the fuel was cheap.. maybe it is commercially when you're buying millions of gallons, but small amount of jet fuel £1/L and avgas £2/L
You're probably quite safe there unless there's absolutely no wind at all, which is very rareI don't think either of them are taxed, so if tax was added, that would actually be very expensive indeed, and planes burn a lot of fuel, especially on take off.
Not sure if I really wanted to know that avgas still has lead in it. I often moor right underneath the take off end of Rickmansworth airfield, entirely used by avgas fueled planes. So my brain, which presumably absorbed plenty of lead in childhood, is now getting a top up.
Might explain a lot!
Nearly all light aviation engines are of an older generation and have to be operated as the designer/producer states. Getting a new design certified is a very long expensive process.TEL is still used in avgas, i believe
Not a very windy area, as it goes, quite a long way inland for Britain.You're probably quite safe there unless there's absolutely no wind at all, which is very rare
At least the lead isn't solid. And pointyAnd that is even without the rain of lead to worry about!
The widebeams aren't very pointy either, but heavy, so they can still do a lot of damage.At least the lead isn't solid. And pointy
