| Subject: | Re: ofcom gobbledegook ?? |
This is what I have done for my aircraft and installation. I have attached t
o the aircraft documents the following:
I have undertaken an assessment required by Ofcom to determine the risk of e
xposure to harmful EMF radiation from equipment installed and determined the
following.
FLARM Equipment: The radiated power is below that required for an assessment
.
VHF Handheld Radio: The radiated power is below that required for assessment
.
VHF Radio: The manufactures stated specification for nominal output power i
s 6 watt. The radio is used for less than 90 seconds in any 6 minute period a
nd is therefore compliant.
Transponder: I have undertaken an assessment an determined that with a manuf
actures specified output of 125 watt and a duty cycle of 0.55% the radiated p
ower is less than 4 watt. The compliance distance required is determined as l
ess than 26cm (0.26m). The antenna is mounted in the rear fuselage and is mo
re than 26 cm from the passenger compartment and is is only selected to tran
smit prior to take-of and deselected as part of the after landing checks.
=46rom the above assessment I have determined that there is no risk of EMF e
xposure to the General Public from any transmitter equipment installed in th
is aircraft.
This is specific to my aircraft but hope that helps.

PS I am a retired radar engineer and provided the technical feedback/advice o
n compliance to the CAA and Ofcom through AOPA.

The LAA guidance link is contained in the Latest News section of the
website
http://www.lightaircraftassociation.co.uk/2021/News/Ofcom_guidance.html
As Alan says, OFCOM have backed off and now recognise (we hope) that our
little aircraft are no threat and they are owned by people who are not
experts in the subject. As a result of input from the LAA and AOPA , OFCOM
have issued simplified guidance see

Here is a picture of the tool on the blade. I use a digital level to level the
blade. The laser will shine a spot on the floor and you mark it. Then do the same
for the other blades and match all spots. You end up with same angle on all
blades with great resolution. I tested for repeatability and it is very good.
