Flashcards in SECTION 3 AERODROME CONTROL - Chapter 5 AERODROME MILITARY AIRCRAFT OPERATIONS Deck (24):
1

Military Aircraft Formations

Formations operate from Gibraltar with prior agreement between the Military Detachment Cdr and the Stn Cdr/RAF Duty Officer

2

Military Formation Landings

Formations may be given permission to land in turn if they land off the first approach or subsequently after a Run and Break.
Phraseology
“C/S 1 Cleared to Land”`
“C/S 2 Cleared to land in turn”
If any aircraft wishes to Touch and Go or Low Approach from the first approach then they will be regarded as singletons.

3

Military Singleton Landings

Singletons may be given clearance to land providing that the preceding aircraft have progressed past the upwind PAAG markings subject to the following conditions:

4

Runway 27 - Military Land After Conditions:

1. The preceding aircraft are cleared to vacate on to the north or south area of the western turning circle to hold.
2. No emergency or precautionary call has been transmitted by the aircraft occupying the runway.
3. All aircraft are military and have a wingspan of 20m or less. In this context FSATO are considered to be military.
4. Wake Turbulence criteria are applied.
5. Once five aircraft have landed any further landings will only be permitted when the last aircraft to land has backtracked and vacated.

5

Runway 09 - Military Land After Conditions:

1. The preceding aircraft are cleared to vacate on to the north or south aprons without backtracking.
2. No emergency or precautionary call has been transmitted by the aircraft occupying the runway.
3. All aircraft are military. In this context FSATO are considered to be military.
4. Wake Turbulence criteria are applied.

6

Singleton Landing Phraseology

“C/S 1 Cleared to Land
“C/S 2 Cleared to land one on”
“C/S 3 Cleared to land two on”

PAAG Operations
The PAAG system in use at Gibraltar consists oF

four identical rotary friction-type energy absorber units installed in pairs either side of the runway. Aircraft are arrested by engagement of the aircraft’s hook with the 1.25” diameter cable stretched across the runway. The cable is fastened to a nylon tape and the energy of the aircraft is absorbed in rotary friction brakes during the tape pullout.

8

The normal cable state for Gibraltar is with the cables de-rigged. When hook equipped aircraft are operating their normal requirement is

approach cable down and overrun cable up. When mixed hook and non-hook equipped aircraft are operating then the Watch Manager should liaise with RAF Operations in order to establish the required cable state

9

Unless the cables are rigged reference to their position will normally be omitted in RT messages. All aircraft must be advised of the cable state when rigged, as some aircraft may be able to trample the cables when they are up and others when they are down. Aircraft speed will also affect trample clearance.

Warnings of cable position are only required once to each aircraft, rather than on each approach.

10

Hook equipped aircraft are not permitted to make formation take offs when the PAAGs are rigged but are authorised to

make stream take offs provided individual aircraft roll only when the preceding aircraft is airborne.

11

PHRASEOLOGY PAAGS

“C/S approach cables up overrun down”
“C/S approach and overrun cables up”
“C/S cables de-rigged”
“C/S approach and overrun cables rigged and down”

12

PAAG Operations - Technical Details - Nominal aircraft weight

40,000 lb.

13

PAAG Operations - Technical Details - Nominal cable run-out

990ft.

14

PAAG Operations - Technical Details - Maximum engage velocity

160 kts. (PAAG application)
180 kts. (Hook/cable limit)

15

PAAG Operations - Technical Details - Rewind time

2MINS

16

PAAG Operations - Technical Details - PAAG AVAILABILITY

Normally the PAAGs are de-rigged and four hours prior notice is required to rig. They are not available at weekends and public holidays without PPR.

17

PAAG Operations - Technical Details - When rigged the cables are either:

UP. The cable is stretched across the runway and raised three inches above it by rubber doughnuts, ready for engagement.
DOWN. The doughnuts are slid clear of the runway leaving the stretched cable lying on the surface.

18

PAAG Operations - Technical Details - PAAG POSITIONS

RW09 Cable: 1450 ft from the Western Sea Wall.
RW27 Cable: 1500 ft from the Eastern Sea Wall.
These PAAG cable positions are indicated by yellow disc markings across the runway and PAAG lights
Normal operations: approach cable down, overrun cable up.

19

PAAG Operations - Technical Details - PAAG Operations - Approximate Cable Preparation Times

PPR to rig cables: 4 hours
To support, remove supports or re-tension one cable: 4 min
To rig and tension one cable: 15 min
To change runways: 10 min
To reset (if taken by an aircraft and the cable is serviceable): 10 min
To reset (if taken by an aircraft and the cable is unserviceable): 30 min

20

GEF, Callsign

ARRESTOR, are responsible for rigging the cable, although the AFRS are also cleared to raise or lower the cables when necessary.

21

Recovery of Aircraft after a PAAG engagement

Recovery of aircraft and arresting cables after an engagement can be hazardous to those persons employed. ATC are to avoid applying any pressure to expedite runway clearance which may lead to the omission of some essential safety procedures. Medical cover is to remain in the vicinity of the arresting cable until the rewind procedure is completed. Furthermore, although only qualified ground engineers may declare an arresting cable serviceable for use, should such personnel be absent during a disengagement and rewind the AFRS will visually check the equipment for obvious unserviceabilities during the rewind. Once ATC have ascertained from GEF that the engagement weight and speed were within limits and that the equipment appears fit for use, the arresting cable may be used for one further emergency arrest. On completion of that arrest the equipment must be declared unserviceable until the appropriate maintenance has been carried out by GEF personnel.

22

Runway 09 PAAG landing Separation

Landing clearance may be given to a hook equipped aircraft when the preceding aircraft is clear of the pull out area of a PAAG that is rigged and up, provided also that the conditions of 5.1.2 are also met.

23

Runway 27 PAAG Landing Separation

Landing clearance may be given to a hook equipped aircraft when the preceding aircraft is clear of the pull out area of a PAAG that is rigged and up provided also that the conditions of 5.1.2 are met and providing:
1. The preceding aircraft are cleared to vacate on to the north or south area of the western turning circle to hold. No more than two aircraft may be held on the northern area of the turning circle and no more than two aircraft on the southern area of the turning circle.
2. No emergency or precautionary call has been transmitted by the aircraft occupying the runway.
3. Once five aircraft have landed any further landings will only be permitted when the last aircraft to land has backtracked and vacated.

24

Noise protection

Military fixed wing aircraft produce higher noise levels than civilian aircraft. Prior to any movements of these aircraft ADC is to pre-note SAPPHO and the GDP barrier staff so that they can wear ear defenders if required.
