ii.
Proportional Method. For every second off of your planned ETA, change
your IAS by 1 kt and hold this new airspeed for the number of minutes equal to
your GS in miles per minute. For example, you are traveling at 3.0 NM per
minute at a 180 kts GS. If you arrive at a checkpoint 10 seconds early, decrease
your airspeed 10 kts for 3.0 minutes. This relationship can be modified to
optimize timely corrections. You may decrease your airspeed 30 kts for 1
minute or 15 kts for 2 minutes. Again, the amount of time you spend making
the correction depends on how quickly you want the correction to occur.
iii.
Ten Percent Method. To use this method you will need to know the amount of
time to gain or lose. This amount is calculated by taking 10 percent of the
flight-planned GS (10% x 180 kts = 18 kts). The rule states that holding the 10
percent increase or decrease in flight-planned GS for 10 minutes gains or loses
