Malaysia Airlines Flight 370

=== Departure ===
At 00:42 MYT, Flight 370 took off from runway 32R,<ref name="Interim report-March 2015" />{{Rp|1}} and was cleared by [[air traffic control]] (ATC) to climb to [[flight level]] 180{{efn|name=Flight level|Aircraft altitude is given as feet above sea level and measured, at higher altitudes, by air pressure, which [[Atmospheric pressure#Altitude variation|declines]] as altitude above sea level increases. Using a [[International Standard Atmosphere|standard sea level pressure]] and formula, the nominal altitude of a given air pressure can be determined—referred to as the "pressure altitude". A [[flight level]] is the pressure altitude in hundreds of feet. For example, flight level 350 corresponds to an altitude where air pressure is {{convert|179|mmHg|abbr=on}}, which is nominally {{convert|35000|ft|abbr=on|sigfig=3}} but does not indicate the true altitude.}}—approximately {{convert|18000|ft|sigfig=2}}<!-- since result is 4 digits, using 3 significant figures seems too precise. 18000 ft=5486.4m...so using 5500m as opposed to 5490 is not a huge difference -->—on a direct path to navigational [[waypoint]] IGARI (located at {{coord|6|56|12|N|103|35|6|E|type:landmark_scale:4000000|name=Waypoint IGARI}}). Voice analysis has determined that the first officer communicated with ATC while the flight was on the ground and that the Captain communicated with ATC after departure.<ref name="Interim report-March 2015" />{{Rp|21}} Shortly after departure, the flight was transferred from the airport's ATC to "Lumpur Radar" air traffic control on [[Airband|frequency]] 132.6&nbsp;MHz. ATC over peninsular Malaysia and adjacent waters is provided by the Kuala Lumpur [[Area Control Centre]] (ACC); Lumpur Radar is the name of the frequency [[Air traffic control#En route, center, or area control|used for ''en route'' air traffic]].<ref name=FIR-Malaysia /> At 00:46, Lumpur Radar cleared Flight 370 to flight level 350{{efn|name=Flight level}}—approximately {{convert|35000|ft|abbr=on|sigfig=3}}. At 01:01, Flight 370's crew reported to Lumpur Radar that they had reached flight level 350, which they confirmed again at 01:08.<ref name="Interim report-March 2015" />{{Rp|1–2}}<ref name="Preliminary report">{{cite news|title=Documents: Preliminary report on missing Malaysia Airlines Flight 370|url=http://www.cnn.com/interactive/2014/04/world/malaysia-flight-documents/|publisher=Malaysia Department of Civil Aviation|via=CNN|access-date=22 October 2014|archive-date=1 May 2014|archive-url=https://web.archive.org/web/20140501200705/http://www.cnn.com/interactive/2014/04/world/malaysia-flight-documents/|url-status=live}}</ref>
