After just having my IR(R) application rejected by the CAA for the second time I have a query for you all...

Do you log flight time as decimal (a flight from 0900-1015 as 1.25 hours) or Hrs:Mins (same flight as 1:15).

The second rejection was due to the fact that I apparently don't have enough hours logged.
After playing around with the figures in my digital logbook, I've worked out what they've done - they've added up the following flight times:
1
0.9
1
1
1
1.8
1.1
1.25
1.1
1.5
1.5
1
1.1
...and come up with 12hrs 55mins.

Not withstanding the fact that the actual flight times are just to the left of the flight time for them to confirm - surely no-one logs flight times of 1hr 1min?

Well I come up with 15.25 hours.

Question - are you certain that your conversion from hours:minutes to decimal is absolutely accurate?

If yes, then I think they person at the CAA is unable to either add up or use a calculator.

Get your CFI to counter sign your adding up - and re-submit.

Me too, because it seems easiest.

However, decimal hours are allowed and work well too.

The problem that the OP has caused the person adding it up at the CAA is because of the '1.25' entry. A decimal entry of time must be to the nearest 0.1 hour. So 1.25 isn't allowed and a time of 1hour15minutes should have been entered as 1.3 hours.
Seeing 1.25 has caused the CAA to say "oh, these must be minutes"

We used to do that for the tech log... the trouble was that some members of the group could not add up or take away. This was exacerbated when a group member used the GPS flight times to the minute which made the columns not end in 0 or 5!!

What sort of idiot would assume

a) 0.1 is the same as 0.01
or
b) 0.1 is hours/minutes when your job is looking at logbooks where that would be expressed as 0:01

when no one would book a flight if one minute duration anyway?

I would be very amused if your "9minute" flight was between two different airfields 90 odd miles apart... Fastest PA28* in the world? :lol: :lol: :lol:

My logbook has, after the totals on each page, the text "mins/decimal" with the idea that you cross out whichever you're not using.

When I began my PPL my instructor taught me to use decimal. Looking at it in the round now, I think I'd rather be using minutes. I did contemplate changing when I began a new page in my logbook recently, but decided not to bother as I'd probably mess something up shortly afterwards.

Oh! I've always used:
00 - 0.0
05 - 0.1
10 - 0.2
15 - 0.25
20 - 0.3
25 - 0.4
30 - 0.5
35 - 0.6
40 - 0.7
45 - 0.75
50 - 0.8
55 - 0.9

Whilst not quite perfect, I could see the logic - what does you conversion chart look like then?

How many hours of instrument flying did you log?

Was the 15¼ hr to which you refer the total flight time, or the IF time? For the IR(R), the requirement is not less than 15 hr of instrument flying - which obviously does not include taxying, take-off, bad weather visual circuit etc.....
