TTX – 7/8

Before aircraft enters the runway in the interest of expediting traffic.

If pilot accepts, aircraft is required to taxi onto the runway and take-off in one continuous movement.

- surface wind and speed and significant changes thereof, RVR values
- significant meteorological conditions in the take-off and climb-out area.

"C/S hold position, I say again, hold position."

Only responsible for providing pilots with the current or last measured visibility/ceiling/RVR values.

Flight crew is responsible to comply with the prescribed operational minima!

Controller may issue landing or take-off clearance regardless of visibility and/or ceiling conditions.

- sudden occurence of hazards (e.g. unauthorized traffic on final approach or on runway)
- significant variations in the current surface wind (expressed in terms of minimum and maximum values)
- significant changes in the runway surface condition
- changes in the operational status of required visual and non-visual aids
- changes in observed RVR value(s), or changes in the visibility representative of the direction of approach and landing

- not available from intersection not visible to controller
- min. vis prescribed in local procedures
- local considerations shall be defined (airport layout, equipment, met phenomenas)
- aircraft involved shall be handled on same frequency
- flight crew shall be advised of position of any essential traffic on runway!
- runway slope shall not render preceding aircraft invisible to succeeding aircraft
- RB of pilot required, containing: RWY designator, name of intersection, number in departure sequence
- wake turbulence separation shall be applied

- RWY designator
- name of intersection
- number in departure sequence

- "H-AB, line up runway 32, intersection A1, and wait."
...
- "SWR123, line up runway 32, number two for departure, behind a cessna at intersection A1, and wait."

Clearance issued which does not become effective until a specified condition has been satisfied.

Considered to be a runway capacity enhancing procedure. Handle with additional awareness!

- only one acft at the time
- subject of condition shall be NEXT movement (that will pass in front of acft receiving conditional clearance)
- during daylight only
- solely to aircraft (not vehicles)
- acft concerned must be continuously visible to controller and pilot
- each conditional clearance shall relate to one subject only

"SWR 123, behind the landing airbus 340 on short final, line-up runway 32 and wait behind."

On runway which have stop bars activated.

1. Identification
2. Condition – "behind"
3. Description and position of subject of condition
4. Clearance
5. Brief reiteration of condition – "behind"
6. Correct readback acknowledge with "correct"

Acknowledge. "SWR 123, correct."

- aircraft livery (colour, marking, logo) may not match operators name used  in RT callsign (EURO 08 plane)
- limited field view from cockpit for high wind aircraft when on ground (cessna taxi by in front of A380)
- limited field view from cockpit, when other aircraft crossing from 3 to 9 o'clock (in the back)
- similarity of aircraft family types (boeing, airbus etc.)

- ensure you have good two-way communication with all surface vehicles

- ensure you are up to date with aircraft recognition

CLD:
- start-up clearance
- departure clearance

GND:
- taxi clearance

- on request by aircraft when < 15 min delay at HP expected
- when > 15 min expected (unless related to an ATFM slot) advise crew when start may be expected

- on request by aircraft when < 15 min delay at HP expected
- when > 15 min expected (unless related to an ATFM slot) advise crew when start may be expected

pilot

1. clearance limit (normally destination aerodrome)
2. SID designator or route description 
3. initial level (except when included in SID)
4. SSR code
5. any other restrictions (e.g. AFTM slot, instruction relating to frequency change, etc.)

determine position of aircraft; normally pilot's report

normally GND 

(according local procedures, Zurich: APRON)

1. clearance limit (normally RWY holding point); specify RWY to be used for departure
2. route on manouevring area (TWY+RWY designators)
3. information on other aircraft to follow, or which are to be taken into consideration to avoid collisions
4. any other instructions/restrictions

include explicit clearance to cross or instruction to hold short of RWY

pilots acceptance must first be obtained

"advise able to depart from runway XY intersection Z"

- at holding point, OR
- length: >= 900 m -> 50 m from RWY edge
- length: < 900 m -> 30 m from RWY edge

- flight crew is responsible to maintain distance from other aircraft
- ground vehicles are responsible to maintain distance from aircraft and other vehicles

- issue traffic information (when visibility may not allow aircrafts to see each other)
- inform taxiing aircraft of presence, position and intentions of known vehicles in vicinity

- vehicles + pedestrians give way to all aircraft
- emergency vehicles proceeding to assist aircraft in distress have priority over all other traffic
