A Typhoon jet came as close as 20ft to another aircraft as it narrowly avoided a mid-air crash in the skies over Lincolnshire.
The pilot of the RAF plane, which was flying at 350mph, was forced to take evasive action with only the length of a double-decker bus to spare, a report has revealed.
At the time of the incident, he was flying in formation as he led two other Typhoon jets. An official report said the pilots of the fighter jets had assumed a Tucano training plane, which was flying at 161mph, had moved out of the way...
It happened in March but an investigation by the Air Proximity Board has just concluded this week. The incident was rated Cat A.

20 feet is pretty damned close when you're doing 350mph.

At the risk of sounding like a tool, I assumed fast military jets had radar rather than having to "assume"?

You LOOK OUT OF THE F*****g WINDOW in the circuit. Sometimes, despite that, ste happens.

Bloody poor reporting.

As for xxx flew at yy mph. Anyone who tells me that Aircrew fly in mph* is automatically put in the iggy bin along with idiots that refer to 'planes', 'loop the loops' or 'stunt flying'.



*We don't. We fly in Knots (Nautical Miles per hour) for perfectly good reason.** ***





** 1 Nautical mile subtends 1 minute of arc at the centre of the earth on any Great Circle. Additionally it means you can use the '1 in 60 rule' which makes navigation easy, and you can tie said rule into time (because time is based in 60s) which makes speed calculations (such as rate of descent) easy. You can't do that if you work in Statute Miles or Metres.

Go on GG15G, I bet you looped the loop lots of times, back in the day...

Does anyone know why they havent metriced degrees and made a 1000 in a circle yet?

As 360 days didnt work, they could also make 1000 days per year with the odd adjustment sometime, to allow for revo;ution of the sun
100 days per month, 10 months per year
Change the length of time so there are 1000 seconds in a day,
10 seconds per minute, 10 mins per hour, 10 hours per day

I like 60s and 12s cloud9

I'd like to have been privy to that 'discussion' between the captain and the auth. laugh

".. upon landing back at base, he discussed the incident with the authorising officer and decided that an Airprox should be filed".

It is rather ingrained in mathematics. I'm sure it could be done as most core mathematics is done using radians rather than degrees, but I'm not sure there's much benefit if at all. Old people still seem to struggle with decimalised money. It would take some effort to recalibrate everyones' perception of time to metric units.

Something I've always wondered about knots.
From the way they are described surely moving 'one knot' is further at altitude than at surface level?

Instructor estimated 20-50'.

Typhoon pilot said it was more like 100'.

No more than miles per hour would as the definition of the length of a nautical mile is constant and the definition of an hour is constant.

You just move one nautical mile per hour through the air instead of along the ground.

Thanks.

But then surely the hight you fly at means the arc you describe around the earth gets longer to move the same distance along the surface. Hence my question, the way a knot is described makes me think it's equal to a set surface distance, yet fly higher and due to the size of the arc you travel further than the surface distance.

The definition of the Nautical Mile is at the Earth's surface. Yes the arc would get longer the higher you go but the difference between that at the Earth's surface and that at, say, 30,000 ft is not significant.

Mine is in KPH. Which means I fly *considerably* faster than yow.

Unless you fly a Piper Cub, in which case I still win.....
