Ground Effect Runway True Airspeed 
Plane and Pilot
JULY 10, 2025
Since the 7,600-foot main runway was unavailable, I ran the numbers for the lightly-loaded Cardinal for takeoff on the 4,400-foot cross runway. The first half of the takeoff was on a slight downgrade, acceleration seemed OK, and we broke ground about the same time as we crossed the longer Runway 21 Left/3 Right.

What is ground effect? What is the headwind component for a landing on Runway 18 if the tower reports the wind as 215° at 30 knots? Ground effect is most likely to result in which problem? Inability to get airborne even though airspeed is sufficient for normal takeoff needs. It increases engine performance.

I was listening intently to the ASOS for wind or gusts, letting it repeat 5 or 6 times with the exact same report: 9 kts straight down the runway; no gusts. That was the runway we would use to land. It’s worth noting that Shmulik had a close call in the past: a jet pulled onto the runway in front of him with no radio call.
