I have just (0655 on 29/6) done a NEAR EGBT in Telegram and got:

Scanning down, you see that that weather at Luton is nice enough, but it’s pretty shit at Cranfield, which is only 15nm away and 200’ lower.

Until you look a little closer The same is true of Coventry.

I don’t think that the issue has gone away.

I don’t think EGBE (Coventry) currently has a METAR/TAF distributed. The issue must be with the airport or the UK distribution system. All the other reports seem current.

Cranfield and Coventry are the two affected.

My point is that glancing down a list like that it is easy to be fooled. Maybe autorouter or Telegram should add filters?

EGKB Biggin Hill

I thought about that before — possibly mark old METARs/TAFs.

Why would you need filters? Doesn’t the PPL training still emphasise the need to always check the dates on weather reports? It was one the first things taught to me many years ago when learning to fly and trying to interpret all the alphabet soup. It is pretty easy to spot and identifies the airports which do not yet have any reports for the day in question. Weather in the UK can be very localised and this could be useful information.

EGBW, United Kingdom

Or make the time in colours? Red for older ones?

Yes, and a good darwinian sieve to weed out bad pilots User interfaces should be user friendly and not punish mistakes.

Unfortunately Telegram does not allow colors, only bold and italic. I will probably put it in italics.

Because we are humans. It’s easy to overlook an expired METAR or TAF.

I must confess that Autorouter “Final Check” page, which also displays the EOBT in human readable format “A day from now on” or “Two hours from now” has saved me once or twice…

Perhaps list METAR/TAFs that are older than x hours, at the end of the listing, with a divider in between?
