Heading changes consistent with the direction of pedal movements were recorded initially, then the helicopter entered an increasing right yaw contrary to the pilot’s left pedal command. The helicopter reached a radio height3 of approximately 430 ft before descending with a high rotation rate.
Yes, I've read the report (in fact it was me that posted the link here first). But, where in that paragraph does it state what the TDP height was?
Earlier a poster, who would appear to be familiar with the type, posted this:
The TDP is 115ft + the height of the obstacle in your takeoff path so I’d guess a minimum of 250-300ft.
