indicated airspeed. The table located in the In-flight guide

(see Figure 7-1) provides the correct indicated airspeed to

as "Mach, Clock, Squawk"

fly based on temperature. As the pilot accelerates, change

the aircraft transponder code to 4000, indicating an aircraft

at high speed in a formal military training route (MTR). Finally, brief the pilot on how

and where the clock will be started. An acceptable clock brief typically includes the

following:

"Crew, for low-level entry we will hack abeam the tree line on the peninsula now at 12

o'clock. The call will be "Ready, ready, NOW."

7.12.1.2.2.1. There are two approved methods to enter the low-level route:

!" irect: Visually extend your course line from your entry point to establish a point on

course about 5 NM (1 minute) prior. Maneuver your aircraft to cross that point on

course. Make BDHI corrections as necessary inbound to the entry point.

!" utbound Parallel: Fly abeam your entry point at a distance equal to one turn

diameter (about 4-5 NM for most aircraft). Fly the reciprocal of your first course for

one minute outbound then turn inbound. At the completion of your turn you should

be on course 1 minute prior to the entry point. Make BDHI corrections as necessary.

NOTE: Route entry is your responsibility and either method is acceptable. While the goal is to

enter on the altitude, airspeed and course for the first leg, there are situations where a modified

entry is necessary due to time, fuel or airspace constraints. Your instructor will brief these

exceptions.

7.12.1.2.2.2. Clock: With the entry point visible in front of the aircraft, pick a point

abeam it for starting the clock. Because the entry point is directly beneath the aircraft at

entry, the point abeam provides a visual reference for starting the clock. While one may

use a personal stopwatch, starting the aircraft's clock at entry is mandatory and the

priority.

7.12.1.3. Route Exit

7.12.1.3.1. After completing the low-level route, a common mistake is to become

complacent in the "post-target" environment. Do not forget the target is also a low-level

turn point! Immediately after target cross over give the pilot a heading, altitude, and

change the transponder code to 1200. As the aircraft climbs, prompt the pilot for the
