3.10 Contingencies Within MNPS Airspace 3.10.1 This guidance material should enable the pilot and the air traffic controller to better understand what actions to take under certain conditions of equipment failure and during encounters with turbulence. A pilot should notify ATC of any contingency that affects the ability of the aircraft to maintain the CFL (particularly in RVSM Airspace. Together they should coordinate a plan of action. Examples of notifiable equipment failures area) failure of all automatic AKDs onboard the aircraft b) full or partial loss of redundancy of altimetry systems aboard the aircraft c) loss of thrust on an engine necessitating descent or d) any other equipment failure affecting the ability to maintain CFL; 3.10.2 However, it is recognized that both a pilot and controller will use their judgement to determine the action most appropriate to any given situation. For certain equipment failures, the safest course of action maybe for the aircraft to continue in MNPS Airspace while the pilot and controller take precautionary action to protect separation. For extreme cases of equipment failure, the safest course of action maybe for the aircraft to leave MNPS Airspace after obtaining a revised ATC clearance. If unable to obtain such prior clearance then the pilot should execute a contingency manoeuvre and leave the assigned route or track, as specified in the ‘NAT’ Section, of the ICAO “Regional Supplementary Procedures” (Doc.7030).
