The British army has been urged to stop the practice of hovering low flying helicopters over homes in the Magilligan and Ballykelly areas.
SDLP assembly member, John Dallat and his Limavady council party colleague Gerry Mullan raised the issue with the British army's civil representative this week.
They also complained about the number of British army Land Rovers using narrow lanes and roads in the area, calling on the army to use main roads were possible.
A British army spokesman rejected both criticisms.
He said both helicopter flights and the use of Land Rovers in the area were operational matters which he would not comment on.
Following their meeting with the Northern Ireland Office's civil representative, Mr Dallat said his delegation raised the question of helicopters hovering over homes unnecessarily.
"We made it clear to the civil representative that we want to work positively to ensure that the rights of our constituents are respected and their privacy is not violated by helicopters or indeed high level cameras pointed at their homes," he said. Mr Dallat said a recent survey showed there was an improvement in the standard of British army driving on narrow roads in the area.
"We accept that as progress. Nevertheless we would want to see an end to Land Rovers and other vehicles using narrow roads when there are alternative routes involving less risk to other road users and pedestrians," he said.
Mr Dallat said he hoped to hold another meeting with the civil representative to discuss the continued practice of closing off the area while soldiers practised on Magilligan firing range.
"This is a prime tourist area that needs to become sustainable.
"That is only possible if it is to benefit from the normalisation process.
"There is no more positive way to do that than make the area accessible at all times to the public," he said.
A British army spokesman said the firing range had been used at Magilligan for more than 100 years.
He said that access to a nearby beach was curtailed during use but was clear on most evenings.
He said the Ministry of Defence had about 12 such firing ranges and there was no reason to stop using them.
