Slight thread drift if I may;
Just relaxing in the Cu Lodge here in Takikawa with a glass of red before heading out for a feed. Glider towing today was interesting to say the least with the thickest haze from humidity I have ever seen!
The max temp for the day was around 29C with very light and variable winds and seeing that this time of year is the tail end of the rainy season, quite often we see very hazy days.
As the day progressed the wind speed dropped and the haze progressively thickened.
All the launches I flew today were to 1500' agl except for the last one. The last launch was the club's Fox Glider (Fully aerobatic)and supposed to be to 3100' agl for an aerobatic practice.
Passing through 2100' I noticed that the haze was so bad that horizontal visibility would have been less than 4000M and the vertical vis was worse! (Can someone explain that?
) And at 2500' the Fox pilot called the excercise off and asked me to take him directly overhead the field.
After he released I turned away and to my surprise found myself effectively IMC for about 15 seconds!
Thankfully the towplane, a Robin R400 has a standard panel (AH, DG etc)
It almost seemed like fog! An education, to say the least.
