Rarely IFR, it only takes a moment to spin the wheel and check time/distance/speed stuff...not like you're head down for any length of time.

This, I use it quite often in VFR for computing groundspeed

Its not like P51s had to scan for aircraft when they were cruising on their way to Japan hundreds of miles out.

Yes they did....


You ever tried flying in AH without looking for enemy fighters?

Well I guess you can do that. I usually approximate those things to +/-2min (or +/-5min for greater distances) given my groundspeed it correct.

How? To do that you need your winds, if your aircraft can tell you the winds than it can also tell you your groundspeed, if you don't have your winds than you need to use the winds that you checked before T/O therefore you might as well get your GS before T/O. The winds you ask the tower are on the deck, you can also ask FSS but they can only tell you the forecast which you could have got before T/O yourself.

You don't need the wind for groudspeed...you only need the time between two points.  Back to the books for you!!  :D

Oh that kind of GS, I thought he was talking about the current GS. Your right that would work.

My avionics tell me all that stuff these days so I don't really have to calculate it  :bolt:

I keep one of these in my car in case the opportunity to fly comes up unexpectedly.

Just an extra formula or two vs the E6B.



Aluminum E6B sure don't like the salt air near the florida coast.

That's not an E6B, it's called CR3 (CR5 in your case)  :D

Right, I'm an idiot.

 :bolt:



I really like it's front side, but I can never get used to the back. E6B is so much easier to use for the winds.
