REFLECTOR: spinner and Howard Handelman

[John Dibble]

David,
David,

I've flown with and without a spinner and don't see any difference.

Here's what I did to improve my approaches.  First, get at a comfortable 
altitude and determine your power setting to get 90 kn and 500 fpm 
descent.  Then, when abeam the numbers in the pattern, cut power to idle 
until you slow to 90 kn/500 fpm.  Then add your predetermined power 
setting and leave it there until you have the runway made, then cut 
power.  It's also important to keep your pattern distance consistent.  I 
set up the final approach course in my gps and use the cdi to indicate 
where 1 mile from the approach course is to establish my desired 
position when down wind.
