REFLECTOR: CLEAN SPEED OR JUST SPEED? [heur]

[Scott Baker]

Guessing gear doors add 5-knots.
No real need for main gear doors other than to help reduce some drag.
Front gear doors keep out the wind (obvious).
I'll check with Scott Swing (who has more info on this) but Vle should be 
able to be raised to 130KIAS without gear doors ... perhaps higher.
Eliminating gear doors eliminates work and eliminates the likelihood of 
their departing the aircraft and going through the propeller.

I still haven't gotten an answer to my original question.  Is there a need 
for gear doors other than speed?  I have all the speed I want at this point 
and they're not on?

And for those flying ... how much speed do gear doors REALLY add?

Info please?  I am still very green in the sky.

WhoooHoo!  That's moving!  You'll be running down Barons at that speed!

Yes, GPS groundspeed point to point, then back again averages out to a
little over 230 MPH.

Tom;



Only reason to have them is to reduce drag - more speed.  I have heard
before that they make little difference.  Now what we'd really like you to
do is get good cruise speed data w/o them, and then put them on and see what
difference it makes. (Always looking for data:-)).



Have you verified the IAS with another on-board source, like a GPS?  Sounds
like it is flying real well.  Marrion would be pleased.

Help me out here guys ... I am test flying ... getting more than 200 knots
(indicated) at 75% power (and yes, my airspeed indicator, pitot and static
system has been calibrated by Denver Avionics).



This speed is without main gear doors and inspection plates on the underside
of the wings.



Naturally, I want to cover up the wing bolt holes ... but what about gear
doors?



This may sound silly ... but if I'm getting this much speed now, do I need
them?



Is there a reason (other than speed) to have them?



Any feedback willl be most appreciative.
