Yes Professor Bill - In a Lancair you can go down or you can slow down= but=20 you can't do both at the same time - It's the Luddite first law for decent= =20 descent planning.

VFR approaches to an airport can be thought about in the same way - 15= =20 miles out get to some reasonable altitude, then spend the next 5 or so= =20 getting to approach speed, the next five stabilized and the last 5 calmly= =20 maneuvering for the "pattern" and landing.  Of course, this assumes yo= u are=20 going to forego the overhead approach technique of blasting in at close to= =20 cruise speed, pulling sharply up to drain the speed whilst quickly configur= ing=20 for the landing and finishing off nicely to the applause of those already s= afely=20 on the ground....

Wha= t are=20 your thoughts on adding speed brakes to a NA ES? Although I am still flyi= ng in=20 Phase 1, I can feel the extra difficulties in "coming down and slowing do= wn".=20 The combination of a sleek airframe and no gear to throw down adds notice= able=20 speed to descents.

I did p= ose=20 this question to the ES group and got mixed reactions, although most feel= they=20 are not necessary, and several do not use them even though they are equip= ped=20 with them.

Anyone have a set of brakes they want to part with if I= move=20 forward on this?
