Mandatory reporting points

It's not as hard as you think. The good news is you can still be 3 minutes off and still be good.



60 kts ground speed is one mile per minute, therefore:



90 kts is 11/2 mi per minute



120 kts is 2 mi per minute



150 kts is 2 1/2 mi per minute



180 kts is 3 miles per minute



Anything faster is just bragging and a lie ;)

I was somewhat joking, but 3 minutes doesn't seem like much, now I give you 142 knots and 47 miles, math gets a little harder. Ballparking it I could get to 20 minutes but probably would follow up with a quick calc with ipad calculator, not sure of the penalty if my math was wrong and ATC came back with "are you there yet?"

Ah, but could you work it at eye level with one hand while scanning for traffic, like you can with an E6b?

I would probably just take my ground speed from my Ipad, enter it into the E6B (kts/60), and just read off for the distance of the leg remaining. Easy peasy. No need to punch in buttons, divide or multiply.

Eh, that's doable in your head. 47/14 is right around 3.3, times 6 is about 19.8 mins.

As said above "N12345 radar contact lost."

Time is important because ATC is using that for separation. That's why TAS changes (10 kts / 5 %) is important. as well as greater than 3 mins at your next fix. ATC is separating by time and in some cases DME.

You're right, there aren't many compulsory reporting points out east but if ATC loses radar you can bet they'll be telling you to report any fix that's needed for separation.

Small, but important point: it's actually 3 minutes or greater. Two minutes, you're okay, 3 minutes... you need to give ATC a new estimate.

Correct. Good point.

I will add that the 10 kts or 5 % I put in there is at all times and not just non radar. It's just more important in the non radar environment than during radar.

Internationally, yes. Domestic, the standard is more than 3 minutes.

From AIM 5.3.2

(b) A corrected estimate at anytime it becomes apparent that an estimate as previously submitted is in error in excess of 3 minutes. For flights in the North Atlantic (NAT), a revised estimate is required if the error is 3 minutes or more.

Yeah, I knew it was greater than 3 minutes. Who flys the North Atlantic anyway? :)

See... that's what I get for opening my mouth. :sigh: :wink2:

You are absolutely right, of course. To be honest, now with ADS-C and CPDLC, I can't even remember that last time I made a voice position report.:dunno:

Thank for the correction!

Oh please, airline pilots or anyone who has been flying for a long time are some of the worst phraseology offenders around. Slang, not acknowledging with their call signs, excess verbiage etc. Don't link military to poor phraseology when they use the same standards as civilians.

Where do you think those now-civilians learned all that non-standard-ology :goofy:

Don't sweat it. Separation is based on controller estimates, not pilots'.
 
Don't feel bad. I had to look it up before I posted. Too many North Atlantic crossings.:lol:

Why is this a "scary question," as stated by whomever tagged this post?
