Narrative:

While taxiing to the active runway at den (8R) we observed a potential jet blast hazard. Request that tower controllers be advised of the following problem. Planes going to runway 8R are told to cross runway 8L at taxiway 'C4.' because of the length of line of planes facing west on 'C' the last aircraft is facing south with his tail to runway 8L. We observed 2 regional sized aircraft cleared to takeoff on 8L while an airliner had his tail to 8L on 'C4.' a heavy aircraft using breakaway thrust might disrupt the takeoff roll of a smaller aircraft on 8L. (Control on runway).

Title: FO OF ACR MLG ACFT CONCERNED ABOUT ACFT JET BLAST AFFECTING ACFT TKOF ON RWY BEHIND HOLDING ACFT ON TAXIWAY.

Narrative: WHILE TAXIING TO THE ACTIVE RWY AT DEN (8R) WE OBSERVED A POTENTIAL JET BLAST HAZARD. REQUEST THAT TWR CTLRS BE ADVISED OF THE FOLLOWING PROBLEM. PLANES GOING TO RWY 8R ARE TOLD TO CROSS RWY 8L AT TAXIWAY 'C4.' BECAUSE OF THE LENGTH OF LINE OF PLANES FACING W ON 'C' THE LAST ACFT IS FACING S WITH HIS TAIL TO RWY 8L. WE OBSERVED 2 REGIONAL SIZED ACFT CLRED TO TKOF ON 8L WHILE AN AIRLINER HAD HIS TAIL TO 8L ON 'C4.' A HVY ACFT USING BREAKAWAY THRUST MIGHT DISRUPT THE TKOF ROLL OF A SMALLER ACFT ON 8L. (CTL ON RWY).
