When is a sunny day IFR?
When the haze is thick in summer. In the Washington DC area lately the temperatures have been very high, that’s cooking the crud that we humans put in the air and making haze. This morning several major local airports were marginal VFR (MVFR) on what’s otherwise a great day due to this haze.IFR; it’s not just for rainy days!I’m not flying today, but I was up recently on a hazy day but where the visibility is better than today’s is. I was just up for a regular self-guided currency exercise. I didn’t cross the Blue Ridge because I couldn’t see the other side.I did my stalls, slow flight, flight at minimum controllable airspeed, steep turns, turns around a point, and some compass turns just to keep up the practice on basic exercises. It’s not that I need to do stalls or any of the above in normal flying, but that practicing them hones skills and reminds me of where the edges of the plane’s capabilities - and mine - are located.Oh, and it can be fun too. I got slow flight to 50 mph (not knots - I have an older plane) with engine power up, a steep angle, and the stall horn blaring loudly.
