Nav Planning Tools - Old Style

[airpolice]

Are you able to give us a rough cost at this time, or is that as long as a piece of....


I'll get me coat.

[airpolice]

Roger has been in touch, and it seems we may still be able to get this excellent piece of kit.

The power of pprune!

Well played Airpolice ... I sent him an eMail this morning to try and encourage an appearance

If a mere yottie may enter the fray, one of the most useful bits of nav kit on my boat has always been a Douglas protractor with a yard of string attached to the centre point. Very useful for a quick course to steer when things are becoming emotional.

Raise you, alisoncc.... This one is a bit careworn, but the case does have the instructions on it, should you forget how to use it.

My Douglas protractor caused a mild stir amongst my USAF Nav colleagues when I turned up with it back in 1970. I had a few sent over from the UK and spread them around and I know that one later did sterling service in AC-130s at nights over the Ho Chi Minh Trail. I can't recall the details but I was told that it proved ideal for the task in hand. (And I never really got the hang of using the USAF protractor for astro plotting and consistently did that RAF-style.)

Airsound ...

I lost my cardboard sleeve for my Douglas a long time ago ... but it still sits proudly in my DIY Tool Bag having found it very useful for drawing cut lines for tiles and flooring etc !

Nice to see a fellow Mac Man

Best ...

if I cut a number of lengths of string (non-stretchy of course) and mark each of them up for appropriate speeds and map scales, would you blokes buy them from me?

Given the ease of laying the string alongside the latitude scale of the map and marking it with your chinagraph, you may not find too many starters ... still, we live in an era where instant gratification is king, so perhaps you'll sell a million! Good luck.


Talking about other nav gear, though, I still have my Naviders

Two quick pinpoints vs time > groundspeed > set speed and get time intervals from there, too easy!

Wouldn't want to put in my trousers pocket though.

They came in a little hard case that stopped the pointy bits doing any damage. Not something you'd want flying around the cockpit in a prang though!

Never give the Nav a sharp object to play with

Never give the Nav a sharp object to play with

Au contraire.

Giving them things like that to play with keeps them busy / quiet / out of your hair.

Cue Monty Python and the stringettes sketch

String

[CoffmanStarter]

I don't suppose these get issued/used in todays world ? IIRC there was a Douglas Protractor printed around the edge of the card's reverse side ... anyway ... it was far simpler to use Heading, Height, Whatever Boxes drawn directly on to your map.

[T-21]

Is it possible to obtain an ex RAF Navigators instruments box ,about one foot square grey coloured ? New or second hand.

Brady Rules

Hi there! I still have some half mil MK-4s and quarter mil MK-1s if anyone wants them. They are still 30 euros. You need to send me your postal address by email at [email protected] with your requirements. Thinking of a GA version, half mil, slow speed with inches and cm scales for general purpose charts but retaining the compass rose as it is. Input welcome. Roger.

[CoffmanStarter]

Thanks for joining the thread Roger

Any chance you could put up a pic ?

Best ...

Coff.

Could someone post a picture of the Hardy Rule please?
