Vertical and lateral FD modes are presented in the FMA displayed on each PFD.

FMA is divided into 2 fields and separated by a vertical cyan line. the left side is the active/captured. The right side is the armed field. Each field presents lateral and vertical mode indications.
Term
Define RTUs
Definition
pg. 17-7: Radio Tuning Units

Used to tune Comm, NAV, ADF and Transponder
Term
Define TCAS RAs
Definition
pg. 17-42: Traffic Collision Avoidance System: Resolution Advisory

25-second surveillance area and is considered a threat.

Preventive RA= avoid a conflict now by maintaining current flight track

Corrective RA= Advises to alter current flight path in the vertical plane. avoid a conflict now by following the command climb or descent.
Term
Define the GPS RNP
Definition
pg. 17-60: Required Navigation Performance

Statement of the navigation performance accuracy necessary for operation within a defined airspace. located on 2nd page of progress screen.
Term
Define PFD
Definition
pg. 10-4: Primary Flight Display

Located on the main panel. 2 screens, 1 for CA other for FO.

Displays airspeed/mach, vertical speed, altitude, attitude, heading, FD command bars, Nav info, flight mode annuciation (FMA) and autopilot info
Term
Define MFD
Definition
pg. 10-6: Multifunction Display

Displays that combine HSI and map display data on selectable navigation formats. can also become reversionary display if PFD or EICAS fails.

Displays HSI, NAV SECTOR, FMS MAP, TCAS, FMS PLAN MAP, RADAR
Term
Define EICAS
Definition
pg. 14-3: engine Indicating Crew Alerting System

Displays the engine instruments, visual and aural crew alert messages and real-time interpretation of aircraft system operation.
Term
Define FDR
Definition
pg 4-36: Flight Data Recorder

CL-65 has a Solid State Flight Data Recorder located in the tail section of the aircraft.

Records the last 25 hours of critical aircraft and flight parameter data.

FDR starts when: Beacon turned on, Strobes turned on, Weight of Wheels.
Term
Define TAT
Definition
Total Air Temperature

TAT is what is measured by the aircraft sensor. When air hits a temperature sensor it effectively stops and the kinetic energy in the air is turned into heat therefore at rest TAT and SAT are the same but at speed TAT is always greater than SAT.
Term
Define SAT
Definition
Static Air Temperature

The true temperature of the air around an aircraft.
Term
Define ADSHCs
Definition
pg 13-12: Air Data Sensor Heater Controllers

Anti-ice control logic guarantees that the probes and sensors are heated prior to takeoff regardless of the PROBE switch position.
Term
Define HYD SOV
Definition
Shut Off Valves

Used to stop the flow of Hydraulic Fluid in a given position.
Term
Define FUEL SOV
Definition
Shut Off Valves

Used to stop the flow of fuel in a given position.
Term
Define SECU
Definition
pg. 9-21: Spoiler Electronic Control Unit

Controls the extension/retraction of the spoilerons, flight spoilers and ground lift dumping system.
Term
Define PACKs
Definition
pg. 7-4: Pneumatic Air Conditioning Kit

2 Pneumatic Air Conditioning Kits that can heat or cool the cabin (R pack) or Flight Deck (L pack) if one is lost it provides a 70/30% split to provide opposite side enough air to help ease the pain inside the WiSCOD.
Term
Define CPC
Definition
pg. 7-14: Cabin Pressure Controller

2 CPCs control all phases of pressurization in the auto mode. Only 1 is activated at any given time. the backup is on standby ready to take control if the other is lost.

There are 8 modes: Ground, Prepressurization, takeoff Abort, Flight Abort, Climb, Cruise, Descent and Landing modes.

Im to Lazy to describe each one so look at pg 7-14 - 7-16.
Term
Define ADG
Definition
pg. 6-16: Air-Driven Generator

ADG provides "last hope" power. 115Vac, 400Hz and 15kVA to power the essential buses in-flight when all other generators are inoperative.

exaggerates and gives credit ti the CL-65's nick name--- WiSCOD!!
Term

displayed as in a range from 00-20 units. each unit is 35*c (Hot as shit)

Green: 00 to 05
White: 06 to 12
Red: 13 to 20

a red number that is in the green means that it once was red and needs to be inspected because you probably warped the brakes with that landing you just accomplished. Good job...
