Study Notes
Aviation Accidents and Safety
- Report aviation accidents if an aircraft is missing, people are severely injured by an aircraft, or an aircraft suffers severe damage that affects its performance.
Balanced Field Length
- If V1 is reached, continue the takeoff and climb to 35 feet at the end of the runway.
Fuel Measurement
- A capacitable fuel gauge measures fuel mass and is independent of temperature influences.
- Note: A capacitable fuel gauge provides a margin against buffet.
Minimum Equipment List (MEL)
- MEL is used during a defect period.
Density Altitude
- An increase in density altitude decreases the high buffet speed and increases the low buffet speed, resulting in a decrease in the buffet range margin.
Aircraft Design
- Dihedral provides stability about the longitudinal axis.
Marshaling Signals
- Marshaling signals are used to identify the gate, indicate when to stop, and when to move chocks; they also signal left engine fire (refer to AIM).
Precision Approach Path Indicators (PAPI)
- PAPI has an eye-to-wheel distance (ETW) of 12.5ft, which is suitable for runways CFS R/W 01 and 19 only.
- There are different types of PAPI:
- P1: ETW up to 10ft
- P2: ETW up to 25ft
- P3: ETW up to 45ft
- VASIS (Visual Approach Slope Indication System) is used in conjunction with PAPI:
- Wide body AC: use upper and middle bar
- Normal AC: use downwind and middle bar
Controlled Flight into Terrain (CFIT)
- To prevent CFIT, maintain situation awareness, know the terrain, and understand the function of the Ground Proximity Warning System (GPWS).
Jet Engine Thrust Reverse
- Thrust reverse in a jet engine involves redirecting exhaust gases forward.
Causes of Compressor Stall
- Inadequate fuel flow to primary fuel nozzles due to improper scheduling by the fuel control unit can trigger compressor stall.
- Below-normal temperatures in the power turbine section impact compressor performance, potentially leading to stall.
- Excessive angle of attack on compressor blades can disrupt airflow and contribute to stall conditions.
- Stator blade warping, especially at high Engine Pressure Ratio (EPR) settings, can result in compressor stall.
Identifying Compressor Stall Symptoms
- Predominant symptoms include:
- Loud explosive bangs indicating sudden disruptions in engine operation.
- Lower Exhaust Gas Temperature (EGT) or Interstage Turbine Temperature (ITT) readings signal reduced engine performance.
- Higher than normal fuel flow can occur as the system attempts to compensate for airflow disruptions.
- Engine surging, characterized by rapid fluctuations in engine power and performance, reflects instability during stall.
- Other potential indicators of compressor stall may include high oil temperature, lower torque or N1 readings, and altered compressor readings, but these are less definitive.
