(See SPECIAL USE AIRSPACE.) 
(See ICAO term RESTRICTED AREA.) 

RESTRICTED AREA [ICAO]

−

 An airspace of 

defined dimensions, above the land areas or territorial 
waters of a State, within which the flight of aircraft 
is restricted in accordance with certain specified 
conditions. 

RESUME NORMAL SPEED

−

  Used by ATC to 

advise a pilot to resume an aircraft’s normal operating 
speed. It is issued to terminate a speed adjustment 
where no published speed restrictions apply. It does 
not delete speed restrictions in published procedures 
of upcoming segments of flight. This does not relieve 
the pilot of those speed restrictions that are applicable 
to 14 CFR Section 91.117. 

RESUME OWN NAVIGATION

−

 Used by ATC to 

advise a pilot to resume his/her own navigational 
responsibility. It is issued after completion of a radar 
vector or when radar contact is lost while the aircraft 
is being radar vectored. 

(See RADAR CONTACT LOST.) 
(See RADAR SERVICE TERMINATED.

RESUME PUBLISHED SPEED

−

 Used by ATC to 

advise a pilot to resume published speed restrictions 
that are applicable to a SID, STAR, or other 
instrument procedure. It is issued to terminate a speed 
adjustment where speed restrictions are published on 
a charted procedure.
