Daily Checks are required and recurring aircraft inspections that must be completed?
GOM
Once per Calendar Day.
It is not required that this inspection be completed before the first flight of the Calendar Day.
Service Check is a required and recurring aircraft inspection that?
GOM
Expires 72 hours after its completion and is more thorough than a Daily Check.
Since a Service check is a more in-depth inspection, it satisfies the Daily Check requirement for that Calendar Day.
A Pre-departure Check is used when?
An aircraft has not flown since its last Service Check.
A Pre-departure Check may be given in lieu of a Daily Check.
This is a lower level check than a Daily Check and is not commonly used.
As needed or Other inspections are required on an as needed basis. What are some examples?
»Overweight landings
»Lightning strikes
»Hail events in flight or on the ground
»Hydraulic leak re-inspections
»Inspections required per an MEL procedure
»Bird strikes
ETOPS Pre-departure Service Check is a required inspection prior to every ETOPS Segment, How many hours is the inspectiong good for?
The inspection and sign-off must occur within four hours of departure.
Block out more than 4 hours after inspection shall require a new inspection to be performed.
Describe a Logbook Preflight:
a) Ensure the correct Logbook for the aircraft is onboard.
b) There must be at least 10 previous log pages to include log pages for at least 3 flight days on board.
c) Confirm that all required inspections have been performed and signed off.
d) Verify and cross check any MEL deferrals with the flight release.
Any discrepancies must be resolved.
e) Ensure that all corrective action blocks have been completely filled out and no open write ups are present..
All aircraft components must be functioning properly or
deferred in accordance with an MEL, CDL, or COI. Describe each?
✈Minimum Equipment List (MEL): documents broken/inoperative aircraft components or equipment (e.g. a blank lower EICAS display) GMM 4.5 A.5
✈Configuration Deviation List (CDL): documents missing components (e.g. the door that covers the GPU receptacle). These often incur fuel burn penalties and may require an updated TLR GMM 4.5 A. 6
✈Carry Over Item (COI): documents aircraft defects that are within limits, but which must eventually be corrected (e.g. Paint missing from the radome, dents in the aircraft skin etc.) GMM 4.6 A.
MEL Categories: A deferred item must be resolved within a specified period of time. This is indicated by the MEL category, what are the time limits for each category?
“A” - As assigned in the MEL (e.g. within 2 flights)
“B” - 3 Calendar Days
“C” - 10 Calendar Days
“D” - 120 Calendar Days
“M” and “O”Procedures
MEL deferrals often require actions to be performed by Maintenance and/or adjustments to Flight Crew operating practices.
Describe the “M” and “O” Procedures?
“M” Procedures: Procedures that must be accomplished by maintenance personnel (or flight crew for a Flight Crew Deferred Item) in order to deactivate and/or inspect the status of a deferred item.
“O” Procedures: A procedure or information advising the Flight Crew of modified procedures associated with a particular MEL.
MEL Stickers: Why, Where and how?
➠Yellow stickers are used to visually indicate the presence of an MEL deferred item.
➠The MEL Control number shall be recorded on the sticker. ➝A control number is a serial number used to identify a particular deferred item on an aircraft in the Maintenance computer system.
➠The sticker will be placed as directed by the MEL manual under “Sticker Location” (e.g. next to the switch that controls the deferred item or adjacent to the Upper EICAS screen)
Describe Flight Crew Deferrable Status?
➢Most MEL procedures require an authorized mechanic to defer the item. These items are not Flight Crew Deferrable.
➢Other items may be deferred by the Flight Crew either at the gate or on the ground after pushback.
➢Whether a particular MEL may be completed by the Flight Crew is indicated in the MEL manual as part of the deferral description.
Until the takeoff thrust is set what manual is controlling for discrepancies?
After takeoff thrust is set, what manual is controlling?
➠On the ground and before setting thrust for takeoff, the MEL manual is controlling. This means any issues at the gate, during pushback, or during taxi out must be resolved in accordance with the MEL Manual.
➠Issues arising after thrust is advanced for takeoff in accordance with the QRH. If the takeoff is continued, the QRH is consulted and it is the Captain’s prerogative to continue to the destination or return to the departure airport.
Maintenance will place Work Requests on the current log book page for items that require in-flight action by the Flight Crew. What are some examples of this?
Common examples include Autoland Evaluations and APU In-flight Starts.
✈A documented Autoland by each aircraft is required every 30 days in order to maintain Cat III currency. Maintenance tracks this requirement and inserts an “open write-up” in the logbook when an Autoland is required. Autolandings are documented in the Autoland portion of each log book page for tracking.
✈A Cold Soaked APU In-flight Start (aircraft at cruise altitude with the APU off for at least 2 hours prior to start attempt) is required for an aircraft to maintain ETOPS status.
What is the Flight Crew deferral process?
If an issue arises after push back but prior to the takeoff, run the associated QRH checklist as applicable:
Consult the MEL manual to see if the item can be deferred.
✈If Yes, consult Maintenance Control to complete the deferral process.
✈If Not, consult Maintenance Control to confirm, then return to the gate for assistance from maintenance personnel.
➢To initiate a Flight Crew Deferral, contact Maintenance Control and document the issue on a Discrepancy block of the current log page.
➢Fill out the Corrective Action block of the discrepancy as directed by Maintenance Control.
➢Add the deferral to the front cover of the MEL section of the logbook.
➢Complete a Yellow MEL Sticker and place it as directed by the MEL manual.
➢Contact the flight follower to amend the flight release with MEL details and any other required changes (e.g. additional fuel required before takeoff per the MEL)

Autothrottle use is recommended when?
During takeoff and climb in either automatic or manual flight.
During all other phases of flight, autothrottle use is recommended only when the autopilot is engaged.
Boeing defines Decision Speed as?
➤V1 is defined as the maximum speed during takeoff at which the pilot must take the first action (reduce thrust, deploy speed-brakes, apply brakes) to stop the airplane within the accelerate-stop distance.
➤V1 is not a decision speed, but the maximum speed for initiating a rejected takeoff. A pilot will typically require 1-2 seconds or longer to perceive, interpret, and react to an RTO scenario.
➤Thus, the decision to stop must be made prior to V1.
What are the concerns regarding RTOs Beyond V1 Speed?
➘Continuing takeoff with an engine failure occurring 2 seconds PRIOR to V1 results in a 15-20-foot lower height above the runway threshold during a field length limited takeoff.
➚Rejecting a takeoff 2 seconds AFTER V1 results in a B767-300 departing the end of the runway at 70 knots and overrunning by 650 feet during a field length limited takeoff.
The Go/Stop decision must be made well before V1 because?
Once we hit V1 we go, because there may not be enough runway in front of us to stop anymore.
V1 is the end of the go/no-go decision making process, not the beginning.
It is a common error in the air carrier industry to regard and treat V1 as a “decision speed”.
What is the definition of V1?
√ What that means to us in plain English, is unless the thrust levers are already at idle PRIOR to V1, the takeoff must be continued
Unless the Captain determines the aircraft will not fly.
Accelerating through 80 knots marks the crossover point between a Low Speed RTO and a High Speed RTO. Kinetic energy increases how with weight and speed?
Kinetic energy increases proportionally with weight but exponentially with speed.
The FCOM 1 states that, prior to 80 knots, takeoff should be rejected for any of the following:
What three items should be called out above 80 knots?
➙ Activation of the Master Caution
➙ System Failure(s)
➙ Unusual Noise or Vibration
➙ Tire Failure
➙ Abnormally Slow Acceleration
➙ Takeoff Configuration Warning
➙ Side Window Opens
(As well as the critical situations listed below)
★ Fire or Fire Warning
★ Engine Failure
★ Aircraft Unsafe or Unable to Fly
Remember to call out any unsafe condition on the takeoff run.
Prior to flight, all mechanical issues must be deferred under a valid and applicable?
MEL
The MEL manual is controlling.
“Flight” officially begins when the thrust levers are advanced with the intention of flight. When a mechanical issue arrises after flight has begun what book becomes controlling?
Once flight has begun, the QRH becomes controlling.
