250 knots is 2531.7 feet in 6 seconds.


I've been a Unix SysAdm since '84, but your response is too arcane for
me. What is that 'bc' or something?

Actually, the n knots ~= 10n fps is a useful piece of trivia.

Damn decimal places.... :-)

I appreciate the correction.

Now if we could only get MontJet Inc. to move a few decimal places
too...

Did you see the "new improved" updated numbers - from the MontJet thread? I
need to get Williams International to move a few digits ...FJ44 ...FJ33
....and hopefully, a new FJ22 for the MontJet!

MontJet: (415 kts/FL450)
(Range: 1,500+ miles)
Empty Weight ............600 lbs (x6 = S-33)
Fuel (4 hrs)..................600 lbs @ 21.5 gph (7 lbs/gal)
Pilot + stuff .................260 lbs
MTOW .....................1,460 lbs (x5 = S33)

Spectrum 33: (415 kts/FL450)
(Range: 2,000 miles)
Empty Wt. ...............3,620 lbs
MTOW .....................7,300 lbs

BTW, I'm using the same engine as the Spectrum 33:
Engine ................................290 lbs
Williams FJ33-4A [1,568 pound-thrust]

Unless a smaller (less fuel burn) FJ22 becomes available! g

flying"

It does happen but not even 50% of the time. Yesterday I saw one
below me and 1-2 miles away before ATC told me about him. That is not
the norm.

How often do you spot traffic called out to you by ATC?

Maybe 50-75% of the time. Just this morning there was an aircraft on
final to a parallel runway ( I was behind him) but I never saw him
until he was airborne after his T&G.

Yesterday, in severe clear VMC (with summer haze keeping the visibility
down to a mere 50 miles or so) on an IFR flight. My wife says "there's
traffic right ahead of us, just a little bit below us!" I said "I don't
see it." She gets more insistent. I still don't see it. She suggests I
ask ATC for a position report on it. I still don't see it, but she's
getting a bit anxious about it. Finally I twig to what she's seeing.
There is a very bright white object on the ground, about 10-20 degrees
below the nose. I had seen it and dismissed it as a ground object minutes
before she pointed it out, so I didn't immediately realize what she was
talking about. I point out that it's not moving relative to the other
objects on the ground, and it is moving relative to the windshield and she
reluctantly conceeds that it's probably on the ground.

One of the reasons I fly IFR and I fly between 8000 and 10000 feet is
because while it doesn't guarantee any separation, it does keep me away
from the $100 hamburger crowd down at 3000 feet, and it bumps me up the
priority queue for getting traffic callouts above the VFR flight following
guys. We flew for 3 hours down to AGC and back this weekend and the only
planes we saw were just before landing back at ROC. But my wife is still
anxious as hell about mid air collisions. If somebody else checks in with
the controller at the same altitude as us, she's almost panicing. I have
to explain that the other guy called in 15 miles north of Bradford
descending to a landing at Bradford, while we're 20 miles south of
Bradford and not descending, so we're unlikely to see him. Any
suggestions how to reassure her?

Even though it's imperfect, my passengers seem to find great comfort
in the on-board traffic sensor display. Its little brother (Avidyne
TAS600) is only about 10 AMU now (using existing MFD/GPS as a
display).

Upgrade to a mode-S transponder and then display the TIS information on
your moving map. The entire NY State Thruway corridor, including your home
airport, is covered by the TIS network.

That assumes that this system will be around a while. Seems like it
or something like it is not long for this world so buying equipment to
use it may not be worth it.
