SARON (Airplane Operation) Flashcards
Emergency training procedures for pilots: when is it required and how often:
Required annually.
Where practical training is during initial training; only required every 3 years thereafter
Touchdown zone is:
The first 3000ft of runway or first 1/3, whichever less
When can pilots partake in elementary work?
Pilot must be trained and approved by company
Does elementary work require a maintenance release?
No; no signature from AME required, only needs to be logged (i.e. adding 1qt oil) and signed by person who did the work.
PILOT CANNOT REPLACE A BETTERY
With respect to a new journey log you should provide continuity by:
Retain the last relevant previous entries from old logbook
When on a test flight with maintenance, who signs the logbook off and in the end, considers the aircraft “released”?
PIC shall have last say whether the ‘repaired’ equipment is valid or not; he/she shall state whether the flight test was successful or not
What is density altitude?
Pressure altitude corrected for non-standard temperature
As temp increase, air density decreases
Weight shift formula:
weight to be moved / total weight
change in CG / distance moved
If approaching faster than Vref, what is the best technique for landing?
(mains, reverse, nose, brakes)
- Land firmly
- Lower nose quickly
- Apply heavy braking
In a constant descent, weight will equal:
Vertical component of lift and drag
Engine Pressure Ratio (EPR) compares:
Pt7 turbine discharge pressure
to
Pt2 compressor inlet pressure
Exhaust divided by Inlet
The amount of energy imported to the airstream by the jet engine
How will high density affect a a turbocharged engine?
Turbocharged engine will provide sea level performance, but it will not overcome:
- Decreased propeller efficiency
- Increased IAS
- Decreased climb gradients
- Increased takeoff/landing roll
- IAS REMAINS THE SAME
“Low energy regime” is:
- Aircraft in landing config with gear down
- In descent
- Thrust stabilized in idle range
- Airspeed decreasing
- Aircraft 50ft or less from touching on runway
Includes contacting ground
What is a balked landing?
Aircraft touches down after entering the low energy regime and goes around
In flight you experience a strong updraft. This will affect stall speed because of:
Influence on angle of attack; air is hitting aircraft from below, causing the aircrafts relative angle to wind to increase
De-ice equipped aircraft have been certified for providing protection against ice during:
In-flight ONLY!
Stall warnings are calibrated to give an effective warning under stat meteorologic conditions?
Under clean wing conditions
Type II fluid:
- Yellow in color
- Glycol & water mixture, WITH added thickeners which causes it to act as a gel
- Type II applied after a hot type I applied
- Longer holdover times than type I
- Vr speeds of 100kts or more, due to its thickness and ability to stick to critical surfaces
Type I fluid:
- Orange in color
- Glycol & water mixture
- Applied hot
- May be used as an “anti-icing fluid” if conditions on ground are not likely for the formation of ice (ground temp. over 0)
- Provides some protection against refreezing but not much after accumulation
- Deemed no longer effective when its ability to absorb more precip. has been exceeded
- removes already accumulated contamination
Type III Fluid:
- Color TBA
- Properties between type I and II
- Freezing point depressant (FPD)
- Vr speeds of 60kts good for up to 100kts
Type IV fluid:
- Green in color
- Type IV applied after type I applied
- Significantly longer HOT than type II
- Should only be used on Vr above 100kts
- Most major airports use type IV exclusively
What part of the A/C gets deiced first?
Surfaces most visible to pilots; i.e. wingtips
Can you takeoff with frost on the underside of the wing?
Yes, according to the manufacturer.
If frost is localized to the fuel cell and not the entire full length of the wing. 3mm to 1/8”
EWH definition:
Vertical distance from pilot’s eyes to lowest portion of the aircraft in landing configuration at Vref; allues to if landing gear are extended!
AP PAPI EWH:

0ft to 10ft (4 lights; normal 4 bar)
P2 PAPI EWH:
10ft to 25ft
P3 PAPI EWH:
25ft to 45ft
A small aircraft using P3 PAPIs will land ____ to the runway.
Too far down; aircraft will be higher than what you should be. Less EWH distance
Aircraft with an EWH of >25ft using a 3-bar VASI shall be indicating what to show they’re on slope?
Use upwind and middle lights only. So top 2 lights, bottom light in a 3-bar VASI means nothing.
Indication from top to bottom shall be red, white, white
shows high because the rest of the plane is below you
PAPIs at certified airports provide a safe obstruction clearance of __ degrees either side out to __NM from runway threshold
6 degrees out to 4NM
longer runways are commonly protected out to 9 degrees either side; exceptions will be noted in CFS
What is V2 speed?
- Speed attained at 35ft above runway with engine failure at critical engine failure speed (VCEF) or;
- Speed 20% above stall speed, whichever greater
- Is the minimum recommended climb-out speed
- Must be, at all times, be 10% above minimum control speed (VMCA)
Minimum speed that must be achieved before initiating a climb
What is V1 speed?
- Takeoff decision speed
- Engine failure recognition at or above this speed will permit a takeoff to continue and be 35ft withing takeoff distance
- Engine failure below this speed permits a stop on the runway within ASDA (accel-stop-dist. avail)
- V1 will not be less than Vmcg (min control speed on ground) or greater than Vr or Vmbe (max brake energy limit speed)
critical engine failure speed
What is a balanced field length?
Accelerate/go distance = accelerate/stop distance
*Where V1 is at the same point on Accel/go and Accel/stop.
For a given runway length, this results inMAXIMUM ALLOWABLE TAKEOFF WEIGHT.
For a given weight, this results in LEAST RUNWAY LENGTH REQURIED FOR TAKEOFF
It is where the aircraft can come to a stop at very end of runway (accel-stop), OR where the aircraft could be at 35ft (accel-go)
Runway clearway definition:
- 250ft on either side of runway centreline

What is a stopway?
Basically the extended part of the runway that is at least as wide as the runway and able to support weight of aircraft during aborted takeoff. i.e. chevrons at JFK
Landing distance definition LDA:
A point 50ft above runway down to where the aircraft stops.
Vmbe speed:
Max brake energy limit speed: Where a stop on the ground can be accomplished within the energy limitations of the brakes

3 Design features to prevent compressor stalls:
- Variable inlet guide vanes
- Compressor bleed valve
- Fuel metering (FCU or EFC)
What is the main function of a compressor bleed valve:
Helps prevent compressor stall.
When turbulent air enters the compressor, the bleed valve can open and “dump” the stagnant/jammed air before it develops further down into the compressor turbine stages
At LOW RPM!
3 Types of reversers:
Cascade
Blocker/target
Bucket
In a cascade reverser, what air is reversed?
COLD bypass air
In a bucket reverser/target type, what air is reversed?
No bypass air, so just HOT non-bypass air is reversed
How is fuel quantity measured? How is it corrected?
A “float” is used to measure it by volume and is uncorrected for temperature and pressure
How is fuel weight measured?
“Capacitance” system measures molecules of fuel present; no the amount it takes up.
(essentially hooking up a electrical circuit to run through and it measures the fuel amount)
Therefore, pressure and temperature does not matter
In a gas turbine engine, what condition allows control of blade angle and fuel control?
Beta range
What is the low-pitch stop?
a hydro-mechanical stop prevents inadvertent reverse in flight!
What do you see when in BETA range on instruments?
