Yes, at high weights and with any engine bleeds, RIPS or air-con (not to mention mission equipment 'sticking out in the breeze') you will be lucky to get much above 150 Kts TAS.

Besides - you should be following the SOPs for your company, surely?

Ok albatross I rephrase:

According to the chart you supplied (figure 3:16) in those given conditions with an aircraft weight of 22000lbs (yes very light) in theory you should get around 144 IAS and 160 TAS, or I am reading it wrong?

Im talking about time critical SAR/HEMS missions were you are interested to go as fast as possible, but of course stay within limits but also feel that the aircraft not gona fall apart on you...or that you start feeling worried...

SAC always gona give u happy figures and refer to the FM (FM says MCP 86 tq, but most operators fly well below that, is it only due to ff or?)
I though I might get a comment from someone flying the S92 in the SAR role, and there experience from high cruise settings/speeds.

Always good to know how to get best range but also the best speed.

Alt , press, temp, wind and TQ (and ac weight and penalties from hoist, sx 16 and so on) are all in the equation...

Thanks again for all the comments.

Remember there are enought charts to choke a horse and that one is ISA +10 @6000.

You had best find a S+R person to give you better info.
