Thanks, soddit, you saved me having to post that. <img src="smile.gif" border="0"> Cough, FYI, if my memory serves me correctly, the (CAA-mandated) accuracy of a VOR is +/- 2 degrees, on an NDB it's +/- 5 degrees. I'm sure someone will point it out if I've got the numbers wrong.

As cough and others have pointed out, in practice there's no reason why we can't track outbound on the 067 bearing from CHT and arrive in the general vicinity of BPK - I'm sure that ATC won't mind if we're 3 degrees out over such a short distance (would they even notice?? :) ). However, unless the law has changed since I last looked at it, (and, again, I'm sure someone will correct me if I'm wrong) it is illegal in the UK to fly a SID without the nominated navaid being serviceable. In the unfortunate, and hopefully very unlikely, event of an incident, the first question the insurance assessor will ask (as he's busy writing out a Refusal of Claim) will be along the lines of "So, Captain, at what stage did you decide to ignore the law and fly an illegal procedure?"

Sorry, Gonzo, my licence isn't worth it.

I am fairly certain that our LATCC colleagues are not daft ( that should get me a few direct routeings) and they would not promulgate a clearance without good reason,BPK u/s or not.For those with long memories it is possible to find points in space through radials/bearings and distances from other stations and I'm sure BPK can be defined thus.If the F50 crew need any more help with their navigational endeavours they could try following the railway line north from Potters Bar,notwithstanding their heroic efforts so far (sense of humour alert).Toodle pip.....

Best fly out of LGW, very seldom do you fly the SID - nice and easy radar steers,not sure why they even bother publishing SIDs.

Numbers you mention seem to correct to my knowledge.

Tired,

Could you point me towards the legislation you describe, please? On a night shift tonight so a bit of light reading would go down well <img src="cool.gif" border="0"> .

Gonzo.

"Hello Croyden, Hello Croyden, this is aircraft #1"

"Aircraft #1, this is Croyden, switch on your transmitter on for 30 seconds and standby for position report"

Gonzo, unfortuantely not, it's been a few years. It was in the AIP somewhere......!. .(That should keep you busy for the evening <img src="smile.gif" border="0"> )

Tired, now you're just being cruel. It was one night shift, not a whole 6 day cycle of nights!

&lt;&lt;Gonzo, unfortuantely not, it's been a few years. It was in the AIP somewhere......!. .&gt;&gt;

Caught your reply too late, but will try to look it up next cycle!

Gonzo.

Can anyone at work look up the rule about dispatch in Europe without rnav?

I think it is now very difficult to fly IFR without Rnav. (from memory the detail of just. .how much you are restricted depend on which country you are in).
