1. START-UP

Start-up procedures are not applicable.

When a departing turbine-engine IFR aircraft requests start-up, the AFIS unit:

a. advises that there are no start-up restrictions, or

b. advises factors which may influence the aircraft’s start-up (other traffic, aerodrome conditions, ATFM SLOT restrictions), after which the pilot-in-command starts-up at his / her own discretion.

2. HOLDING BEFORE TAKE-OFF

When, due to other traffic, an immediate take-off is not possible, a departing aircraft shall hold on the parking stand on the apron.

3. TAKE-OFF

Take-offs are performed in the order in which the aircraft have reported being ready. This order may, however, be altered if required by the traffic situation or by pilots’ mutual agreement.

Note: Before take-off, the “runway free” report shall be obtained from the AFIS unit.

4. SELECTION OF THE RUNWAY-IN-USE

Normally, an aircraft should land and take-off into the wind unless safety, the runway configuration, meteorological conditions, available instrument approach procedures or air traffic conditions determine that a different direction is preferable. In selecting the runway, however, the AFIS officer takes into consideration, besides surface wind speed and direction, other relevant factors such as the aerodrome traffic circuit, the length of runway and the approach and landing aids available.

The AFIS officer may suggest the runway-in-use with a tail-wind component provided if AFIS or the aircraft gain an operational advantage and the pilots accept the tail-wind component. The final decision on the acceptability of the selected RWY rests with the pilot.

5. MOVEMENT OF VEHICLES AND PERSONS ON THE MANOEUVRING AREA

Procedures for the control of vehicles and persons on the manoeuvring area are similar to those applied at airports where ATC is provided. Vehicles and persons are not allowed on the manoeuvring area when an aircraft is taking-off or landing.

6. DE-ICING PROCEDURES

6.1 Aircraft de-icing shall be carried out in areas specifically designated by the airport.

6.4 De-icing on apron will take place with aircraft engines off.

6.5 After de-icing is completed and de-icing team has reverted to a safe position, de-icing operator will report “de-icing completed” and anti-icing code and start time if any to the crew.

6.6 After de-icing taxiing shall be commenced only after receiving an “all clear” (thumbs-up) signal from the ground staff.

7. UNMANNED AIRCRAFT SYSTEM FLIGHTS IN LIEPAJA TIZ
