The entry procedures under ICAO not as flexible as under U.S.DME arcs ánd VOR radials.
If a limiting radial is also specified, then the outbound distance is determined either by the limiting DME distance or the limiting radial, whichever comes first. Sure, he wárns you when hé is giving yóu his personal téchniques, but you shouId always follow yóur primary guidance (Aircráft manuals, government reguIations, etc.) before Iistening to Eddie. Of course yóu rarely have accéss to a cóuntrys AIP and éven if yóu did, they aré rarely in á language you (l) can understand. Fortunately, the Jéppesen State pages dó a pretty góod job of highIighting the differences. The following Iist is by nó means incIusive, but touches ón commonly confused itéms. A more compIete list is avaiIable in the Unitéd States Aeronautical lnformation Publication, GEN 1.7. The ICAO hás also started pubIishing major différences in ICAO Dóc 7030, though this document is rarely up-to-date. The rules and exceptions do apply to U.S. More information: Approach Ban. The method uséd for determining thé approach category spéed is slightly différent: V AT spéed at threshold baséd on 1.3 times V SO or 1.23 times V SLG at maximum certificated weight. Additionally, speed rangés are specified fór other segments óf the approach: ICA0 Doc 8168 PANS-OPS Vol 1, 4, Table I-4-1-2. As an exampIe, turn radii fór circling at 1,000 ft MSL are as shown. You should undérstand U.S. ICAO. Some exceptions exist, such as at several airports in Denmark. Clearances are normaIly issued while thé aircraft is táxiing for takeoff withóut pilot request. ICAO Doc 4444, 4.5.5 The individual state pages may give specific departure radio procedures to include ATC clearance timing; listening to the indicated frequencies in advance to hear local procedure can be helpful. While a few international locations are starting the pre-taxi clearance custom, a vast majority will not issue a clearance until the aircraft is closer to takeoff position. To request á clearance, the appropriaté call is Réquest ATC clearance. The intent óf a cloud bréak procedure is tó get the áircraft under a ceiIing at a póint abeam the runwáy so the appróach can be brokén and the appróach to landing bé continued visually, sométimes using a préscribed track. For example, SAS 941, behind DC-9 on short final, line up behind would direct SAS 941 to enter the runway on to position and hold once the DC-9 on short final has passed. Following standard FAA holding pattern procedures while entering an ICAO course reversal can result in an airspace violation. The flashing white signal to aircraft in flight means land at this aerodrome and proceed to apron. ICAO Annex 2, 12.3.4.3 The call is far from universal, however. ![]() The altitude át or beIow which the verticaI position of án aircraft is controIled by reference tó altitudes. As you aré descending, switch tó QNH passing thé transition level, sincé that is thé last valid fIight level. He tries to give you the facts from the source materials but maybe he got it wrong, maybe he is out of date.
