Are Dry Microbursts Really An Invisible Trap? – Responding to Reactions

Chess In the Air

Possible causes include: Rotor turbulence, e.g. on wave days. In still air, the climb rate under full power is likely in the range of 3-5 kts given the high density altitude environment at Rifle. In some situations this may require a pattern entry at 2000-3000 ft AGL). This is another great point.

Chess In the Air

He only needed a glide ratio of 14:1 to reach the airfield to arrive at a typical pattern altitude of 1,000 ft AGL. At this point he still had an altitude of 8,275 ft MSL, i.e. 2,739 ft AGL. At this point he was just NW of the runway at an altitude of 8000 ft MSL (2464 AGL).
