1. If there is no active precipitation, does the holdover time still start at the start of the second stage (if it is two stage)?
2. Decode this Type 2/75/0630/08 Jan 02?
I thought possibly Type 2/ 75/25 /Holdover starts 06:30Z/8th Jan 02
Cheers in advance

Type 2/75/0630/08 Jan 02
a) type 2 fluid
b) 75 = 75% fluid (25% water) [not for type 1]
c) LOCAL time when final stage of de-icing commenced
d) local date

Strictly speaking the Type of fluid should be quoted using Roman numerals, i.e TYPE II

Not sure I agree with the statement that local time is used.
Z usually refers to GMT, or UTC as our European friends decree.
06.30z in Lima isn't early morning.
Also, here's a question. If you as Captain can't see the surfaces treated, do you accept the word of the person offering you the chit/slip of paper/billet doux or do you don you outside gear and go have a look?
You = $4000 per mnth. Deicer chappy = $1000 per month?

ok, in my company, the time is LOCAL time of start of finall stage
I believe LOCAL Time AND LOCAL date are the accepted format. It does not matter, however, if you are not sure - just append the time zone.
Sir George - NB the 'Z' comes from the 'guess' by 'gatbusdriver', not the tech log entry?
