I emailed you previously top sign up for the Chelton course.  I'm planning on flying into KPIT the day before the course, but I may need to leave earlier that 5pm to get back to NY before dark.  What is the plan for the afternoon?  Any major loss if we leave at 3 or 4 pm?  BTW, know how long I should allow for an IFR departure out of KPIT?  Thanks, Clark Still
