LXGB,
Were you operating in your capacity as a "Military Emergency Controller" when dealing with this pilot?
If not then the pilot was perfectly correct to provide some feedback because you without further explanation tried to use a procedure which if you read CAP413 is part of the procedures for dealing with D+D.
Perhaps you don't remember the old procedures for speechless QGH including the old favourite speechless compass and gyro u/s one. Back then the procedure requried us to remind the speechless aircraft to use 1 for yes and 2 for no and the old "Fly straight and level on primary instruments all turns will be timed by me starting and stopping on the executive word now"
I get the impression that you would not bother with such a statement. After all the pilot should know that should they not?
One wonders who had the comms problem!

Backpacker,
The old triangle system was more for flights that were above cloud......Someone with a big hairy thing on their lip would come up and waggle their wings and you would formate on them while they did a QGH or PAR or whatever was available to get safely down through the cloud.

Foxy Loxy,
The morse code "H"(....) is used by a speechless aircraft to request a QGH (Homing and Controlled Descent) H being for Homing.
These days, 7600 and the European procedures for comms failures are suficient knowledge. i.e. For VFR flights - remain in VMC and land at the nearest suitable aerodrome. Cant get more simple than that.
Regards,
DFC
