MARCH 21, 2025

TSB Approach sequence Due to reported wind gusts as the CRJ900 approached Toronto Pearson following a flight from MinneapolisSaint Paul International Airport (MSP) the aircraft was flown at 149 knots. One second later (2.6seconds before touchdown), the EGPWS alert sink rate sounded, indicating a high rate of descent.

Wind velocity of greater than 20 knots with higher gusts, especially flowing over rough terrain, can lead to an unwelcome flight. Even stable airmass of constant 20 knot winds as it traverses over uneven terrain will cause eddies or burbles, or “potholes in the sky” that will “involuntarily” move the aircraft in its various axes.

But the engineering behind the G7 didn’t wring a few more knots from the carbon fiber airframe by tweaking fairings or FIKI panels. Flap overspeed protection makes for one more improvement, preventing the pilot from deploying the flaps above the programmed indicated airspeed relevant to the flap setting selected.

For a Cessna 172, the recommended indicated airspeed for the maneuver is 105 knots. At this point, you should be flying at the slowest speed (5-10 knots above stall speed). Airspeed ±10 knots from entry airspeed. Lazy eights are typically flown at cruise power settings below maneuvering speed.

This is consistent with Rick’s report, which referenced 9 knots of wind. Without knowing the horizontal wind direction and speed at this point it is impossible to say what his indicated airspeed was. A sudden gust of 50 knots would have caused a stall unless he had been flying at about 100 knots indicated.

To get the extra lift required for the turns, I had to dive to get extra airspeed so that the plane could turn at that same AOA. Tedious numerical interpolation is not required when adjusting airspeed for weight, contrary to the claims of some AOA advocates. That produced a strange traffic pattern with roller coasters at the corners.)
