James Nugent was one of 18 people on a Eurocopter Super Puma flying between an oil platform and Sumburgh Airport on Shetland when it crashed in August.
Four people were killed and others were left seriously hurt, including Mr Nugent, 41, who is no longer able to work offshore.
He said pictures of the Glasgow crash on Friday brought back painful memories of his experience and he hopes the survivors and relatives of those killed are being supported.
Mr Nugent, who lives in Newquay, said: "I know first-hand how difficult it is to begin to move forward following such a horrific ordeal when you are given little support.
"There is very limited information about how the incident occurred and whether steps are being taken to prevent a repeat tragedy.
"I can't believe that so shortly after my crash, there is another Eurocopter tragedy in a large city that has killed the occupants of the helicopter as well as persons on the ground.
"Seeing the harrowing images and reports of the latest crash definitely brings back painful memories and I have no doubt that many of the people in the pub and close by at the time of the crash will be psychologically scarred from witnessing such a horrific ordeal.
"I have learnt from my own experiences that it takes long-term specialist help to allow you to manage living with something like this and I hope all those involved are being offered the support they need."
In its continuing investigation into the crash off Shetland, the Air Accidents Investigation Branch (AAIB) says it has so far found no evidence of any technical failure in the helicopter.
Its latest update, issued in October, said a reduction in airspeed was not noticed by the pilots.
Mr Nugent is being represented by lawyers Irwin Mitchell for a potential compensation claim.
One of the firm's partners, Jim Morris, who is a former RAF pilot, said he is surprised at the nature of the crash in Glasgow and expects the AAIB investigation to be lengthy.
"It is extremely important that the authorities, manufacturers and operators take all possible measures to ensure that there are no further incidents of this type and no further injuries or deaths as a result," he said.
"Similarly to James, all of those affected by the latest incident in Glasgow will want to understand exactly what went wrong and what is being done to improve the flight safety of helicopter operations so that further tragedies can be prevented.
"Our thoughts are with the families of those killed and with those who have been injured in this latest terrible incident."
