B/CA Analysis: Cessna Citation V

P ilotReportwhen this happens.While the low idle is enabled, the amber “groundidle” annunciator light is illuminated on the warningpanel.When the power levers are advanced and weightcomes off the squat-switches, the plunger lets go andlowest obtainable idle is set at 52 percent. There’s aneight-second delay built into the system. For example,when the airplane lands with the switch in the normalposition, the computer will not permit the engines tospool down to ground idle for eight seconds. This willretain high idle during the period in which the landingmight be rejected.The engines will remain at or above flight idle whenthe switch is selected to “high” regardless of the positionof the main gear squat switch. This switch must bein the “high” position when conducting touch-and-goesor when operating on the ground with the engine antiicebleed air on.It should be noted that it takes longer to explain thefunction of this switch than it takes to integrate it intocockpit routines.THE HONEYWELL PACKAGEAnyway, as soon as the engines are started and theinverters and avionics masters are activated, the fiveinchHoneywell EFIS displays wake up and your attentionis drawn to the heart of the panel.The Citation V’s standard avionics package includesa Honeywell SPZ-500 integrated flight director/ autopilotsystem using two five-inch EFIS (EADI and EHSI) indicatorson the pilot’s panel.Electrically powered mechanical ADI and HSI unitsmade by Honeywell are installed on the copilot’spanel. However, EFIS is optionally available for thecopilot’s side, as is a multi-function display (MFD) forthe center panel.The standard flight control system includes altitudealerting and reporting, altitude pre-select and a verticalnavigation system with vertical speed and indicated airspeedhold. An air data computer provides altitudeencoding and output to operate the left-hand servoedaltimeter. Heading information is provided by dual C-14 compass systems. The rest of the avionics suite comprisesdual Collins Proline II remote-mountedcommunications and navigation gear.Joining it all together is a Global Wulfsberg GNS-Xnavigation management system with a built-in Loran-Creceiver. The standard equipped airplane can beapproved for FAR Part 91 Category II operations.Cessna marketing executives told B/CA they electedto make EFIS standard “simply because it’s what customersexpect of a new airplane.
