Instrument Departure Brief

CHAPTER SIX

T-6A INSTRUMENT NAVIGATION

The "time hack" will occur at 1335Z. A countdown to the hack is usually

commenced prior to conducting the time hack.

Student: "On my hack, the time will be 1335Z. 3-2-1 Hack... 1-2-3"

For the minutes and seconds required for turn point procedures, we normally use the elapsed

timer (ET) function of the aircraft clock.

Student: "On my hack, we will start the elapsed timer. 3-2-1 Hack 1-2-3"

NOTE

The ET function of the aircraft's clock displays minutes and

seconds until reaching 59 minutes and 59 seconds, after that, it

displays hours and minutes. If the enroute portion of your flight

will exceed 59 minutes, you will need to re-hack the clock. This

should be done on any leg where a GS can be accomplished in

order to establish an ETA to your next point. This step shall be

accomplished prior to the end of the hour.

603. INSTRUMENT DEPARTURE BRIEF

The Departure Brief describes the departure procedure to be flown by the pilot. It is initiated

after completing the Before Takeoff Checklist and before calling the Tower for takeoff

clearance. The Departure Brief acronym is THAR:

Turn:

First turn/DME.

Heading:

First heading after takeoff.

Altitude:

Initial altitude.

Restriction: Restrictions, if any.

Student: "Departure brief. 1.0 DME past the TACAN, turn right to 150, climb to 3000. No

restrictions."

OPERATIONS CHECKS

The initial Operations Check shall be performed immediately after checking in with Departure.

Subsequent Operations Checks shall be initiated every 20-25 minutes. Ensure the nearest

suitable divert airfield is briefed with all Operations Checks. Your preflight planning should

include identifying the airfields along the route with suitable approaches to use as emergency

diverts.

If you're in VMC, this will be the nearest suitable paved airfield.
