PT3 Flashcards
What is mode A and C for SSR?
A - ID
C - altitude
What is the wavelength for ILS-band
2,7 meter to 2,67 meter (108.100-111.975 mHz)
True or false - APP radar uses longer wavelength compared to Area radar
False
What is the frequency of a wave
Cycles per second
when do you need to use SELCAL?
Around 200 nm away from antenna when flying oceanic
What is the frequency if the wavelength is 2,5 meter?
120 mHz
True or false - optimum frequencies for HF in the oceanic FIRs varies on a daily basis
True
What are used for navigation in air traffic?
VOR, DME, NDB
True or false - area radar uses longer wavelengths compared to APP
True
Are frequencies in HF only Line of sight?
No
What is used for horizontal distances: RVR, Rwy length and visibility
In meters
Does vertical speed indicator take information from both static and pitot or just static?
Only static port
On collision heading, what heading do both aircraft have to turn?
To the right
What is ISA standard pressure?
1013,25 hPa
Does all SVFR need air traffic control?
Yes
Air traffic control is split into which 3?
Area, approach and tower
What indicates an alerting phase?
Not landed within 5 minutes of the estimated time of landing
Who can call “distress traffic ended”?
Only ATS unit controlling
Within class C and D, when does a clearance to VFR flights NOT imply any form of separation?
C - between VFR flights; and
D - between IFR and VFR flights or between VFR flights
Except when t/o and landing, VFR flights shall not fly below what, over congested areas of cities, towns or settlements?
300m(1000ft) above highest obstacle within radius of 600m of aircraft
When do you provide approach control service?
For all arriving and departing aircraft
True or false - ICAO members are encouraged to give notifications if they are not in compliance with recommended practices?
True
With what three parts is the AIP built up?
GEN
ENR
AD
Under what conditions can you fly IFR?
IMC and VMC
Why is clear ice such a problem in aviation?
It is very heavy and can effect aircraft controls and surfaces
What does weight act through on an aircraft?
Center of Gravity
What does lift work through?
Center of pressure
What does standby compass onboard an aircraft point towards?
Magnetic north
What is the biggest different between flaps and slats?
Slats increase the critical angle of attack and flaps increase lift
What are speed brakes for?
Speed brakes are used to increase drag
The altimeter always indicates vertical distance based on…?
The instrument sub-scale (Kollsman window)
The position of the Center of Gravity on an aircraft depends on..
Distribution of aircraft mass and load
In the event that the control column is moved forward, what happens to elevators?
They move downwards
What is the flap setting for t/o?
10-15 degrees
What can you expect, if a pilot reports that his/hers speed brakes/spoilers are inoperative?
- A normal approach, since you don’t use speed brakes for the approach.
- longer roll out due to reduced breaking (longer rwy occupancy time)
- the risk of hot brakes
Getting close to a stall, the point which a boundary layer separates from surface is called?
Separation point
True or false - the pitot/static system is absolutely critical during flight and the are numerous independent systems
True
Why do airlines change from IAS to Mach when climbing above a certain FL?
To make sure that no parts of the aircraft become supersonic
What is difference between anti and de-icing?
Anti icing is protection against future snow and ice, de-icing is removal of existing
According to the Demand-control model, what combination induces high levels of stress and fatigue?
High demand and low sense of control
True or false - You can issue traffic information to a VFR flight based on surveillance without prior identification and notifications to the pilot?
False
What is it to provide information on collision hazards between persons and aircraft on maneuvering area (uncontrolled aerodome)?
Air traffic service
Authorization for an aircraft to proceed under conditions specified by an air traffic control unit” is a clearance or instruction?
Clearance
What is the difference between clearance and instructions?
Clearance is a condition and instruction is specific
At what time do you need to submit flightplan during flight?
10 minute prior
If you fly over a DME in FL180, what will it read?
