PANS-OPS means:
Procedures for Air Navigation Services - Aircraft operations
The document that specifies the recommendations for instrument procedures
is called …
PANS OPS Doc 8168
Which of the following defines transition altitude?
The altitude at which 1013 hPa is set and vertical position then reported as a
flight level
The Transition Level:
Shall be the lowest flight level available for use above the transition altitude
During flight through the transition layer the vertical position of the aircraft
should be expressed as (climb or descent)
Altitude above mean sea level during descent
Transition from altitude to flight level, and vice-versa is done:
At transition altitude during climb and transition level during descent
Which of the following cruising levels would you select under the following
conditions: True track 358°, variation 3°E, deviation 2°W?
FL 65
In the vicinity of an aerodrome that is going to be used by the aircraft the
vertical position of the aircraft shall be expressed in:
Altitude above sea level on or below the transition altitude
The vertical position of an aircraft at or below the transition altitude will be
reported:
As altitude
The transition altitude of an aerodrome should not be below:
4000ft
The pilot of a departing aircraft flying under IFR shall change the altimeter
setting from QNH to standard setting 1013.25hPA when passing:
Transition altitude
In the standard atmosphere FL 150 is equivalent to: (mtr)
4 550 metres
A pre-flight altimeter check should be carried out:
At a known elevation on the aerodrome
Which of the following correctly lists special purpose codes that are to be used
in conjunction with Secondary Surveillance Radar (SSR)?
Distress 7700, Hijacking 7500, Communication failure 7600
When acknowledging mode/code setting instructions, pilots shall:
Read back the mode and code to be set
Pilots shall not operate the SSR special position indicator (IDENT) feature
unless:
Requested by ATC
When the aircraft carries serviceable Mode C equipment, the pilot:
Shall continuously operate this mode unless otherwise directed by ATC
When an aircraft carries a serviceable transponder, the pilot shall operate the
transponder:
At all times during flight, regardless of whether the aircraft is within or outside
airspace where SSR is used for ATS purposes
Your transponder code assigned by ATC is 5320. In flight, in case of radio
communications failure, you will squawk code:
A 7600 Mode C
The pilot of an aircraft losing two-way communication shall set the transponder
to Mode A Code:
7600
When the aircraft carries serviceable Mode C transponder, the pilot shall
continuously operate this mode:
Unless otherwise directed by ATC
During a pre-flight a SSR transponder is found to be inoperative and immediate
repair is not possible:
A flight to the closest airport, where a repair can be made is allowed
When an aircraft is subjected to unlawful interference, the pilot-in-command
shall indicate the situation by setting the transponder to:
7500.
On receipt of a TA, pilots shall:
Not manoeuvre their aircraft in response to traffic advisories (TAs) only
Airborne collision avoidance system {ACAS) indications shall be used by pilots
in:
Both B) and C) are correct
What are the two main objective of altimeter setting?
To provide adequate terrain clearance and vertical separation
Which of the following correctly defines altitude?
Vertical position with reference to MSL
Which of the following correctly defines height?
Vertical position with reference to aerodrome elevation
Which of the following correctly defines flight level?
Vertical position with reference to the standard pressure level
If the QNH is 991 Mb where is FL? {Assume 1 Mb= 30 ft)
Below sea level
Which of the following is the location of FL?
The atmospheric pressure level of 1013.25mb
What is the relationship between IFR and VFR flight level?
For given mag track, the VFR level is the IFR level plus 500’ if below FL290
At what point in a flight is the QNH communicated to the pilot by ATC? During
In the taxi clearance
If you are flying outside an aerodrome traffic zone, what are you required to set
on your altimeter sub scale ?
The local QNH obtained from FIS or the nearest aerodrome
If you are flying en route below the transition level but are well briefed with
regard to safety altitude, from where would you get altimeter setting information
whilst airborne?
Ask the FIS controller for local aerodrome QNHs
You are approaching an aerodrome to land and call the approach controller
at 10nm from the edge of the ATZ. Your flight conditions are VMC and you are
flying VFR. When would you expect to be advised to set the aerodrome QNH?
On clearance to enter the traffic pattern established for a visual join to land
You test your altimeter with aerodrome QNH set. What would a serviceable
altimeter read?
The elevation of the position of the aeroplane plus the height of the altimeter
static vent
In selecting a flight level for a flight, which of the following should be taken into
consideration ?
1. Adequate terrain clearance is ensured
2. ATC requirements (Danger Areas, restricted airspace etc.) are complied with
3. Minimum traffic separation is ensured
4. Adequate separation from VFR traffic is ensured (differential flight levels
applied)
5. The appropriate flight level in accordance with the table of flight levels
The level chosen complies with the table of cruising levels
1, 2 and 5
When are SSR transponders to be operated?
On all commercial flights
You are entering a FIR where SSR is used from an area where SSR is not used.
What would you squawk?
A/2000+C
