Term
What is the significance of 10,000 Feet?
Definition

Air - Maximim altitude for operation after an inflight depresurization is 10,000 feet MSL unless MEA or other constraints require a higher altitude.  

 

Air - Maximim Altitude when the aircraft is dispatched for unpressurized flight is 10,000 feet. 

Term
While Flying at Flaps 45°There are two important airspeed limitations to observe, what are they?
Definition
Momentary Airspeed excursions that are due to wind gusts or turbulence ar allowed up to 155 kts. with no crew or maintenance action required.  Steady State operation over 145 kts. is not allowed and must be entered into the AML.
Term
The risk of structural failure of the vertical stabilizer or the rudder leads to this caution.
Definition
Air - A full or nearly full deflection in one direction followe by a full or nearly full deflection in the other direction, even at speeds below the designed maneuvering speed (200 KIAS), can dramatically increase the risk of structural failure of the vertical stabilizer or rudder.
Term
37,000 Feet is associated with two limiatations.
Definition
  • Altitude (Aircraft) - Maximum operating altitude is 37,000 feet. 
  • APU - Maximum operating altitude is 37,000 feet.  
Term
Which aircraft does the AE3007A 1/3 & the AE3007A1 belong to respectively?
Definition

Rolls Royce AE3007A 1/3 is on the EMB-140

Rolls Royce AE3007A is on the EMB-145

Term
The Automatic Takeoff Thrust Control System (ATTCS) must be armed under what takeoff modes?
Definition
  • The EMB-140 aircraft must have ATTCS armed for takeoffs when using ALT T/O or ALT T/O-1.
  • The EMB-145 aircraft must have ATTCS armed for takeoffs when using           ALT T/O-1".
Term
The main batteries maximum temperature is what in Celcius?
Definition
Maximum battery temperature is 70°C.
Term
There are 5 DC Generators, which one has an additional limit?
Definition
  • Maximum load on main generators is 400 Amps. 
  • Maximum load on the APU generator is 400 Amps up to 30,000 feet and 300 Amps above 30,000 fet.  
Term
In your descent from altitude, after what altitude can you extend the flaps?
Definition
Maximum Altitude for Flap Extension is 20,000 feet MSL.
Term
160 KIAS appears twice in the limitations for different reasons, what are they?
Definition
  • Maximum Airspeed after Takeoff / During Climb without retrimming is 160 KIAS. 
  • Max Wiper Operating Speed; 160 KIAS.

 

 

Term
Why is 10°C an important temperature for Anti-ice / Deice?
Definition

Ground and for Takeoff;

 

Icing conditions exist when the OAT is 10°C or below and visible moisture in any form is present (such as clouds, fog with visibity of one mile or less, rain snow, sleet and ice crystals). Icing conditions also exist when the OAT is 10°C or below when operation on ramps, taxiways or runways where surface snow, ice, standing water or slush may be ingested by the engines or freeze on engines, nacelles or engine sensor probes


Flight;


Icing conditions may exist whenever the Total Air Temperature (TAT), is 10°C or below and visible moisture in any form is present (Such as clouds, fog with visibility of one mile or less, rain, snow, sleet and ice crystals).


Term
884, 717 and 680 refer to what?
Definition
  • Maximum starting EGT is 884° C.
  • The APU Continuous EGT may be exceeded up to 717° C for 5 Minutes.
  • APU Maximum Continuous EGT is 680° C. 
Term
What is the limitation for Automatic Anti-Icing system operation?
Definition
There is no temperature limitation for automatic anti-icing system operation.
Term
Yaw Damper operation is not authorized when?
Definition
  • Takeoff to 500 feet AFL.
  • Landing.
Term
When visual what is the minimum autopilot disengagement altitude?
Definition
For visual approaches it is 1500 feet.
Term
Minimum disengagement of the autopilot when on an approach is when?
Definition
  • MDA
  • DA
  • DH
Term
Engaging the autopilot after takeoff is restricted until what height?
Definition
500 Feet
Term
Day, Night, VFR, IFR, Known Icing and RVSM are what?
Definition
Types of operations authorized.
Term
Besides the Pilot (Captain) & Co-Pilot (First Officer) are there any other required flight crew members?
Definition
No.
Term

With the autopilot coupled on a CAT II ILS approach what is the minimum decision height?  

How many feet can you loose with the autopilot coupled during a go-around?

Definition
  • 100 feet.
  • 50 feet. 
Term
Is the maximum takeoff and tailwind component of 10 knots the same as the tailwind component for a CAT II ILS?
Definition
Yes
Term
Is the maximum demonstrated crosswind for takeoff and landing of 30 knots the same for a CAT II ILS?
Definition
No, the CAT II ILS is maximum crosswind is 15 knots.
Term
Can the APU used as a pneumatic source for the anti-icing system?
Definition
The APU shall not be used as a pneumatic source for the anti-icing system.
Term

The Captain is hand flying, the aircraft is configured for flaps 45° and the ILS is configured, howerver, the AP is not coupled and we just passed the FAF.

 

The weather is 3/4 miles visibility and 150 foot ceiling.  Is this acceptable?

Definition

No.

 

CAT II Appraoch and landing must be made with flaps 22°.

 

All Cat II Approaches must be flown coupled to the AP to DH.
