There is no requirement for pilots to read back ATC clearances
received on the ground unless the clearance differs from the filed
flight plan. However, pilots should clarify any portion of the
clearance not completely understood. In addition, controllers may
require pilots to read back any clearance. During the Instrument
Flight Stage, student pilots will be required to read back all ATC

Amplification An instrument departure is a procedure used to ensure a safe climbout from an
airport and to provide safe separation between aircraft. You will use the following departures
throughout your training and subsequent flying career.
Instrument Departure Procedure
Amplification An instrument departure procedure (DP) is a preplanned IFR air
traffic control departure procedure published for pilot use in either text form or in charted graphic
form. DPs ensure safe transition from the terminal to the appropriate enroute structure and
provide the following advantages:
Graphic and/or textual portrayal of departure route.
Guaranteed obstacle clearance.
Increase efficiency and reduce communications and departure delays.
Approved ATC departure route clearance in the event of radio failure.
Can be designed to support noise abatement programs.
IFR Takeoff Minimums And (Obstacle) Departure Procedures While planning
for the flight the pilot should determine if there are any IFR takeoff minimums and
(obstacle) departure procedures for the departure airport. If an inverted triangle with the
capital letter "T" appears on the departure or approach plate (see Figures 62 and 63) for
the departing airport, a textual departure is located in the section: "IFR TAKEOFF
MINIMUMS AND (OBSTACLE) DEPARTURE PROCEDURES" in the front of the
applicable DOD Flight Information Publication volume that lists the Airport Diagrams,
Instrument Approach Procedures, Departure Procedures and Radar Instrument Approach
Minimums (approach plates). The pilot is expected to review these procedures prior to
departure (Figure 64).
