The helicopter turned left to return to the airport, travelling at about 85 knots. The indicated airspeed had fallen below 65 knots and was still decreasing. The helicopter was at treetop height with an indicated airspeed of zero knots when the right yaw ceased. The pilot reported two miles out.

FAA weather charts can help for higher altitudes but when just a few thousand feet agl, they may be less useful. Flight idle and nose down, which normally produced a 2,000-3,000-feet descent rate, resulted in a 2,000-feet-per-minute climb. We continued our descent into Great Falls, leaving “the wave” behind and above.

Be familiar with what an idling engine and slow gliding speed sound and feel like, what the clean descent rate is, how much altitude is lost during a 180- or 360-degree turn, and what minimum agl altitude you’ll want to have when you arrive abeam of your landing spot. Third, practice for an engine-out emergency on a regular basis.

In the Cessna 172S Pilot’s Operating Handbook (POH), the landing distance decreases by 10% for every 9 knots of headwind. For the Cessna 172, landing distance increases by 10% for every 2 knots of tailwind. Any substantial changes to speed and descent rate will destabilize the landing.

Even though synthetic vision might help me perform an emergency descent to a valley that might not be cloud filled, that’s pretty sketchy as a risk-mitigation strategy. Also, from when I lived out West, there was the mountaintop clearance guideline—1,000 feet for every 10 knots of wind, with 30 knots meaning no-go.

VFR to MVFR…then 2 miles visibility and a ceiling of 1,200 feet agl. Put the aircraft in level flight to give them a moment to consider their next course of action so they are not anxiously doing climbs, descents, and unplanned turns. It might be no greater than 6 knots with gusts to 10 mph. It’s just a few minutes, right?
