TIME

In aviation it is important to know what the current time is. "Time Hack" is a means by which

aircrew men of the same aircraft, flight or mission synchronize their timing devices to either

validate specific events based on time or perform or arrive at certain places at specified times.

For your training, time hack can refer to two scenarios:

The current Local or Zulu time for events such as an EFC from holding.

Minutes and seconds for student responsibilities such as the two-minute prior call.

Setting the current local or Zulu time can be done during the pre-flight brief with wristwatches or

"egg timers." The IP may or may not have you set the "local time" on the aircraft clock. You

must be familiar with whatever type of timing device you choose to use. Do not rely on your

instructor to teach you how to use a clock. Zulu time is the standard time used in aviation but

you may also use local time. The following is an example of how this works for the preflight

brief:
