Bell 412 OEI Performance
Hi. I'm a recent 412 convert. Tend to draw parallels to my previous helo- the ALH (Dhruv). I have a few queries. Grateful if anyone could help.
1. The 412 EP RFM in the Cat A supplement gives a graph that gives "Target Torque" which, say at 30 deg Sea Level, gives a target torque at 2.5 min rating of 65%. However in the limitations section, the OEI torque limit is supposed to be 81%. So what torque would I need to pull? And what is Target Torque???
2. For various ratings, there would be ITT, N1 and Torque limits. I presume the limit you hit first would be the limiting factor for that rating. So, at sea level around 30 deg C what limit would i hit first? No performance graphs let me analyse this.
