Notices to Airmen
Pilots may be requested by ATC to provide an estimate for when the flight can accept the next higher
altitude(s). If requested, pilots should provide this information as soon as possible.
Westbound aircraft entering RVSM or MNPS airspace in the New York FIR:
Pilots should include in the initial position report the time or location that the next higher altitude can be
accepted.
EXAMPLE−
“Global Air 543, 40 north 40 west at 1010, flight level 350, estimating 40 north 50 west at 1110, 40 north 60 west.
Next able flight level 360 at 1035.”
NOTE−
Pilots may include more than one altitude if that information is available.
EXAMPLE−
(after stating initial report) “Able flight level 360 at 1035, able flight level 370 at 1145, able flight level 390 at
1300.”
MANDATORY PILOT REPORTS
In addition to reading back altitude assignments, pilots shall report reaching any altitude assigned within
RVSM airspace. This serves as a double check between pilots and controllers and reduces the possibility of
operational errors. This requirement for altitude readback and reports of reaching assigned altitudes applies
to both RVSM and CVSM altitudes (i.e., flight levels 330, 340, 350, 360, and 370).
EXAMPLE−
(initial altitude readback): “Global Air 543 climbing to flight level 360.”
(upon reaching assigned altitude): “Global Air 543 level at flight level 360.”
CARIBBEAN, SOUTH AMERICA, AND GULF OF MEXICO
FDC 2/8646 ZFW TX.. Due to the lack of terrain and obstacle clearance data, accurate automation data bases
are not available for providing minimum safe altitude warning information to aircraft overflying Mexico. Air
traffic facilities along the United States/Mexico border have inhibited minimum safe altitude warning
computer programs for aircraft operating in Mexican airspace until accurate terrain data can be obtained.

ENHANCEMENT OF THE MEXICO VHF NETWORK
On May 1, 2003 ARINC declared its Mexico VHF Voice Network (MEXNET) operational. This network
is operated as part of the existing ARINC Domestic VHF Network Service, controlled from the ARINC New
York Communications Center on network frequency 130.700 MHz. In 2006, ARINC installed additional
VHF voice ground stations at Villahermosa, (MX/VSA) and Veracruz (MX/VER) to provide improved
enroute and on−ground coverage at these airports. Effective May 1, 2007, the ARINC San Francisco
Communications Center assumed control of this network.
