Ground to air signal strips in WW1?

I've got a TNA file on this. Somewhere. ISTR that the bombing range arrow can from a list of directions to aid aircraft to pursue Zeppelins. I'll start digging.

I have this from AIR1/1816/204/178/6 it includes a booklet entitled "Ground Signals for use between aircraft and Aerodromes"

Hi
I have only just come across this request for information and have joined to try and answer it to some extent.  Reference WW1 there were a whole series of 'ground to air' signal strips, sheets and panels used by different arms and in different theatres of operation on the British side.  For example on the Western Front  Artillery, Infantry, Cavalry and Tanks all had their own manuals with the signal strips they would use when contacting aircraft.  Also there were identifying panels to indicate the command level of the formation plus actual signalling panels to send messages including from 1916 (start of Somme battles) a 'Shutter Panel' to send messages in Morse code, replaced during 1918 by the Popham 'T' Panel (non-Morse system) alongside these generally there would  a series of  ID letters made out of strips.  During the later inter-war period the Popham Panel was replaced by a different type of 'T' panel which was still in use at the start of WW2.  There were also ground signals used for air defence purposes both at home and at the fronts, the 'Ingram Panel' (mentioned in another post) is probably the most famous for home use (a similar signal system was also used at AA Look Out Posts [LOPs] to identify their location to aircraft in Mesopotamia).  Directional arrows were also used at home and abroad, for example at Compass Stations (and AA) on the Western Front  where a June 1917 document describes it as a "White circle 17 yards in diameter with a white arrow 17 yards long and 3 feet. 6 inches wide, with white strips 10 yards long and 3 ft 6 ins wide to indicate height of enemy machine (each strip indicating 2000 feet)". There were variations on this theme and with the signals as they developed during the war and in the various theatres.  Ground signal strips etc. may also be used in conjunction with wireless, lamp and pyrotechnic signalling (this also happened during WW2).
I have written some articles that have been published in Cross & Cockade International, that includes some information on the use of the signals, and at present I am working on a series of articles on various signal systems used during WW1.
In summary the ground strip signals used will depend on the type of formation using them, their purpose and the theatre they were in, although there are always similarities and overlaps.
I hope that helps.

Hi
Is the source you have used AP 1632 'RAF Signal Manual Part V, Ground Signal Code'?
A few examples of use during WW1:

Yes 'Puff practice' was used I believe.
