They may well have just shot their own foot right off.... Calling a Judicial Review, then actually starting your own heli-service is just bonkers! Any legal QC is going to probably make a call of "if its good enough for you to do it - then its good enough for others"
Would also be a very expensive operation that will be incredibly short lived in all probability because they will be paying for SAS to have crews locally based, and due to the number of rotations and days of the week, that will be at least 2 crews on rotation of probably week about.
It will also be operated according to SAS ops manual and for scheduled pax ops / it won't be the same as HEMS or PAS.
On an outsourced basis with such high cycles versus flight time and probably an avg load factor of 7 or less then that is loss-making from the start - and that is without the cost of sales, and IOSSC overheads
If you speak to any of the AW139 SAr guys that operate the same type, operating over / in a salt water environment all day soon takes its toll on required line maintenance - which will be intense..... and thats the same for both operators if they compete!
