Define a Mineshaft Day?
Guessing well below Zero DA This is the ISA Definition of DA at Sea Level International Standard Atmosphere(ISA) Sea level (0 ft. (0km)) altitude, Temperature 59 degrees F (+15c) Barometer of 29.92 inHg). My thinking is set a rule. Such as running 1.20 under at Zero DA or Higher be subject to the rules. Be interesting seeing National Record post with DA, track and day. We have the technology to do this. Should help keep the definition and ruling consistent. |
