Balpa talks over helicopter jobs threat in Aberdeen
As many as 15 pilot jobs are at risk at Bristow Helicopters in Aberdeen, with CHC Helicopter also looking at making cuts.
Bristow said it was proposing 15 redundancies, due to the "challenges the oil and gas industry is experiencing".
The British Airline Pilots' Association said it had begun "urgent negotiations" with the company.
CHC is also currently consulting on possible job losses.
Balpa national officer Mick Brade said of the Bristow news: "We have already had an initial meeting with the company and our urgent talks are ongoing."
Bristow said in a statement: "As a result of the challenges the oil and gas industry is experiencing, the company has announced proposals involving 15 redundancies within our pilot group at Aberdeen.
"We are consulting with our trade unions and employees over these proposals and will do everything we can to support our employees through this difficult process.
"Our focus remains on providing a safe and efficient service throughout the North Sea."
A CHC spokeswoman said: "We are currently focussed on conducting a thorough and fair consultation, working with employees and unions, and supporting those who are affected.
"The offshore industry continues to face challenging conditions and we, like many other businesses, are having to respond to the current environment.
"Difficult decisions must be made but our customers can be assured that safety remains our top priority."
