Indicated Airspeed Runway True Airspeed

Most approaches, even non-GPS approaches, have a waypoint placed exactly at the threshold of the runway. In addition to required visibility, the runway environment must be distinctly visible and identifiable. I think I have the runway lights in sight, is not good enough. And what exactly is the runway environment anyway?

Inbound from the south, the single-engine, retractable-gear Beechcraft entered an uneventful downwind leg for Runway 26. The Bonanza lay crumpled up in an empty lot just 2,400 feet from the approach end of the runway. The pilot continued the turn to final but overshot the extended runway centerline. Not ideal, but not hopeless.

A lighting the runway with under 1000 ft to go, the pilots breathed a sigh of relief. In addition, decreased air density also decreases ram air pressure, meaning a indicated airspeed from a pressure-based airspeed indicator will read lower than the true airspeed.

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.

We found a flaps up, power-off stall speed of 47 mph indicated airspeed, and full-flap stall speed of 42 mph indicated. We did power versus true airspeed checks at 7,500 feet on a standard atmosphere and temperature day. None had trouble keeping the airplane relatively near the runway centerline on rollout.

Particular attention to true airspeed vs. turn radius. What is the runway lighting? Only accurate within 10 degrees of runway heading). If you choose to fly a Circle-to Land approach to a runway without a VASI or PAPI, you are greatly increasing your vertical flight error path (possibility/probability).

This means that if you encounter these conditions on a particular day, you would need to achieve a higher true airspeed to produce the same lift that would be generated at lower airspeeds in denser air. Miscalculating density altitude can lead to runway excursions and fatalities. Resulting in a decreased rate of climb.
