Prop clearance? VG performance

Post by garybcollins »

I have a couple of questions regarding the C170B, specifically S/N 26126 a 1954 bird.

1. What is the prop clearance in level flight attitude? Where is that listed in the specifications?

2. What is the FAA required prop clearance for a taildragger? Where is that to be found? I figure it must be in Part 23 but have not found it.

As a follow-up on the vortex generators:

1. The optimum takeoff configuration with the VGs is 20 degrees of flap. It comes off cleanly at 50 mph and climbs well at 60 mph. With less flap the plane can not be rotated to a high enough angle of attack to make use of the VGs.

2. The nasty loss of elevator with a full flap slip is still there but recovery is much faster.
