6.3.3.3  Arriving aircraft - delay of 10 minutes or more. 7110.65 4-7-11 d 5 
6.5.5.2  Onward clearance time. 7110.65 PG EXPECT FURTHER CLEARANCE (TIME)- The time a pilot can expect to receive clearance beyond a clearance limit 

6.7.3.1.2 Whenever parallel approaches are carried out, separate controllers should be responsible for the sequencing and spacing of arriving aircraft to each runway  U.S. has no criteria for separate radar controllers in conducting Parallel approaches. 
6.7.3.2.9  U.S. has no parallel approach obstacle assessment surfaces (PAOAS) Criteria. 
6.7.3.2.9  U.S. has no criteria for a “45 degree track”. 
6.7.3.2.10 a)  U.S. has no criteria for both controllers to be advised when visual separation is applied. 
6.7.3.5.3 b)  U.S. has no surveillance radar approach (SRA) 
6.7.3.5.3 c)  In the U.S., aircrews may execute visual approaches when the pilot has either the airport or the preceding aircraft in sight and is instructed to follow it. A contact approach is one wherein an aircraft on an IFR flight plan, having an air traffic control authorization, operating clear of clouds with at least 1 mile flight visibility and a reasonable expectation of continuing to the destination airport by visual reference in those conditions, may deviate from the instrument approach procedure and proceed to the destination airport by visual reference to the surface. This approach will only be authorized when requested by the pilot and the reported ground visibility at the destination airport is at least 1 statute mile. 
CHAPTER 7  PROCEDURES FOR AERODROME CONTROL SERVICE 
7.2 SELECTION OF RUNWAY-IN-USE  Except where a “runway use” program is in effect, in the U.S. the runway used will be the one most nearly aligned with the wind when 5 kt or more, or the “calm wind” runway when less than 5 kt unless use of another runway will be operationally advantageous or is requested by a pilot. 
7.4.1.1 START-UP TIME PROCEDURES  U.S. has no start up procedures, taxi clearance. 
7.6.3.2.3.2 Light signal fromaerodrome control  In the U.S., for movements of other than aircraft traffic (i.e., vehicles, equipment, and personnel), steady green means cleared to cross, proceed, go; flashing green is not applicable; flashing white means return to starting point on airport; and alternating red and green means a general warning signal to exercise extreme caution. 
7.6.3.2.3.3 Flashing runway or taxiway lights  U.S. controllers do not flash runway or taxiway lights to instruct aircraft to “vacate the runway and observe the tower for light signal.” 
7.10.2 Clearance to land  In the U.S., landing clearance to a succeeding aircraft in a landing sequence need not be withheld if the controller observes the positions of the aircraft and determines that prescribed runway separation will exist when the aircraft crosses the landing threshold. Controllers issue traffic information to the succeeding aircraft if it has not previously been reported. 
7.11.4 For the purpose of reduced runway separation, aircraft shall be classified as follows: Also Chapter 4,Section 4.9 and Chapter 5, Section 5.8, respectively.  ICAO aircraft wake turbulence categories (heavy, medium, light) and FAA weight classes (heavy, large, small) differ.  Also, for landing aircraft, wake turbulence separation is defined differently.  The U.S. makes special provisions for any aircraft landing behind a B-757 (4 miles for a large aircraft behind or 5 miles for a small aircraft behind). 

7.14 AUTHORIZATION OF SPECIAL VFR FLIGHTS  Special VFR operations may be conducted in the U.S. under the following weather minimums and requirements below 10,000 feet MSL within the airspace contained by the upward extension of the lateral boundaries of the controlled airspace designated to the surface for an airport. These minimums and requirements are found in 14 CFR Section 91.157. Special VFR operations may only be conducted: (1) With an ATC clearance; (2) Clear of clouds; (3) Except for helicopters, when flight visibility is at least 1 statute mile; and (4) Except for helicopters, between sunrise and sunset (or in Alaska, when the sun is 6 degrees or more below the horizon) unless: (i) The person being granted the ATC clearance meets the applicable requirements for instrument flight; and (ii) The aircraft is equipped as required in 14 CFR Sec. 91.205(d). No person may take off or land an aircraft (other than a helicopter) under special VFR: (1) Unless ground visibility is at least 1 statute mile; or (2) If ground visibility is not reported, unless flight visibility is at least 1 statute mile.

8.6.5.2  The U.S. has not implemented cold temperature corrections to the radar minimum vectoring altitude
