Not in this context it doesn't!
Heading
Airspeed
Altitude
Time(r)
pre-HAAT:
Read the Heading off the log and set it on the Hdg bug if you have one. Check DI and compass are synchronised.
Confirm the Airspeed is correct and the a/c is in trim.
Confirm the Altitude is correct and steady.
Check that whatever you're going to use to measure Time is ready to be started ('hacked') at the start point.
Overfly the start point on track, start the timer, note the time.
Then, as soon as possible:
Read the Heading off the DI, check it aaginst the compass, then cross-check it against the log (e.g. is it 123deg or 132 deg?)
Recheck that Airspeed and Altitude are steady and correct.
Check that the Timer is actually running.
Add the leg time to the start time and note down the ETA.
Put map down, LOOKOUT and fly accurately.
1-2 min before the pre-planned visual fix ( a rough fraction of the track length e.g. about 1/3 or 1/4 - or 1/2 if it's a short leg), note the actual elapsed time against the planned elapsed time then, if you've been flying accurately, adjust ETA by adding the appropriate multiple of the difference to the planned ETA. Otherwise, just carry the difference and apply to the ETA.
Do FREDA checks at low activity points, never at turning points. The ancient 'HATFIRE' check was rightly binned many years ago!
Don't get distracted by RT - only use the minimum service you actually need. Remember that VFR means SEE AND AVOID!!
