6.
It is strictly prohibited for aircraft to fly below 4500’ over the area between the Usumacinta River and 30 km from the frontier inside Guatemalan territory. Private aircraft which have to fly over the area will report to RADIO FLORES on 118.3.

(SPEC/CL II NOTAM 016)

7.
All civil pilots when overflying military zones or bases within the Republic should fully identify with pertinent commands indicating name of pilot, type af act, registration, color of aircraft and reason of overflight, changing frequency 126.9 to 126.2 for such purpose.

NATIONAL PROCEDURES

GENERAL INFORMATION/FIR/UIR COVERAGE -This entry includes the Port Au Prince FIR.
DIMENSIONAL UNITS - ICAO Table except:
1.  ALTIMETER SETTING - Hectopascal unit of measurement. (SPEC/GEN 1-2-1)

ALTIMETER SETTING PROCEDURES - Standard
except:
1.
The transition altitude for the Haitian FIR is 17,000’.

2.
Vertical positioning of aircraft when at or below the transition altitude is expressed in terms of altitude, whereas such positioning at or above the transition level is expressed in terms of flight levels. While passing through the transition layer, vertical positioning is expressed in terms of altitude when descending and in terms of flight levels when ascending.

3.
Flight Level zero is located at the atmospheric pressure level of 1013.2 hPa (29.92”). Consecutive flight levels are separated by a pressure interval corresponding to 500’ (152.3 M) in the standard atmosphere.

NOTE:  Examples of the relationship between flight levels and altimeter indications are given in the following table, the metric equivalents being approximate:
Flight Level Altimeter Indication
Number Feet Meters
10  1000 300
15  1500 450
20  2000 600
50  5000 1500
100  10,000 3050
150  15,000 4550
200 20,000 6100 (SPEC/ENR 1.7-1)

VERTICAL SEPARATION - Semi-circular except:
1.
Vertical separation during enroute flight shall be expressed in terms of flight levels at all times during an IFR flight and at night.

2.
IFR flights, and VFR flights above 900 M (3000’), when in level cruising flight, shall be flown at such flight levels, corresponding to the magnetic tracks shown in the following table, so as to provide the required terrain clearance:
