found in Appendix C before embarkation to the site. This task is best carried out at the planning stage whilst
the Pre-Site Survey form is being completed.

Contact Number
Consideration must be given to the Operating Location in relation to crew communication. If the operating
location is likely to be busy or noisy then two way radios should be issued so that crew members can remain
in contact. The Pilot-In-Command will not be given a radio as all communication will be relayed through the
Observer so as not to disturb concentration. The Pre-Site Assessment should have already identified any
possible forms of frequency interference, if there is a possible risk then a frequency spectrum analyser
should be used to assess potential interference. All Leicester Drones crew members must carry a fully
charged mobile phone and ensure they have all of the relevant contact numbers in case of emergencies.
