Non-gyro vectoring
Just out of interest...
...anybody practise / being taught to do this at all anymore? For those who've not heard of it before, it's timed turns based on rate one. In this way, you're not depending on making turns on your bouncing sby compass, but only have to roll in to & out of a rate 1-turn at the ATCOs instruction.
So - anybody?

ATC and the pilot shall prior vectoring agree the rate of turn and the pilot shall commence/stop the instruction on the order "now".
Ex. "Turn left NOW"....."Stop turn NOW"
That what I learned some 15 years ago. Never tried in real life only a simulator

Up until 2 years ago I was working at Llanbedr, where almost every aircraft was vectored as non-compass non-gyro. They were UAV's. Of course, it's closed now sadly, so there's probably less reason to do it. I believe it is still taught as part of the emergencies and unusual circumstances syllabus in the Approach Control Surveillance rating.
Also used it a lot when I worked at Farnborough, where we dealt with Odiham helicopters who had no imagination, so every time they did a practice speechless, they also simulated a compass failure!
It's actually very easy to do, and you can be surprisingly accurate if you do it regularly. To give you an idea, the UAV's at Llanbedr were given no-compass no-gyro PAR's! That was fun!

I stand to be corrected, but is the procedure not "no compas, no gyro" as in no direction information at all? I have done this (both as practice for me and the controller) and it works remarkable well. Flying with a working standby compas on the other hand should be well within the abilities of an average pilot.

We're lucky(?) enough to do this day-in, day-out.
"Adopt the standard no-compass, no-gyro procedure. All turns rate one, starting & stopping on the executive word "NOW"."
"turn left....NOW"
"stop turn....NOW"
Also the speechless procedure.
What larks, Mr Pip! What larks!

We do NCNG SRA's for TRUCE. Also include Tx failure, speechless, short pattern emergency SRAs including curved approaches, and combinations thereof. All on the 424. Plus we take turns in flying the target aircraft. It keeps us amused between movements........

When I was training for my instrument rating (november 2005), and on later flights I / we have been practicing No Gyro ASR approaches a few times under the hood.
I've also heard that here in the US the controllers likes to be asked to provide such services, since they need to stay current.
We get on a separate freq. with a final app. controller.

I cannot be bothered to work out the mathematics regarding rate 1 turns, i explained it to a visiting controller on the flight deck once. it is up to you to find out by familiarisation. i shall check in the books next week when next at work, and if you have not found the solution i shall explain.

There used to be a hunter pilot at Yeoves (one Derek Mortar) who's standard form of recovery was the NCNG One-in-One... often with speechless thrown -in (just to test ATC out?)... Ahhh, the One-in-One; that's what you call controlling?

Its amazing how many ppl imc guys do not know or have never recevied training in the NCNG proceedures. remember these guys have to rely on one vac pump for their gyros. as ire/s we like to throw the proceedure at students during the ppl/ir renewal as an extra element if it applies to the ac they operate. its a shame this training is not a required element of the IR groundschool instead of all the toss in the present syllabus
