take-off: forbidden! except intersection clear of chute or taxi around
landing: single landing allowed, inform about position
Name the 4 types of scramble orders.
- "active air" -> hot/live missions, ordered by CAD/CIND

- "daily ops" -> standard exercises accordint ATO
- "airbase practice" -> maybe even without departure
What info shall be passed to radar in case of a scramble?
1. Callsign
2. Runway in use
3. Flight size (nr of acft)
4. ADDC radio channel
Name the 7 different alert statuses.
A0 -> readiness or MNM 90 minutes
A1 -> take-off within 60 min
A2 -> take-off within 35 min
A3 -> take-off within 15 min, QRA pilot in office, acft ready in shelter
A4 -> take-off within 3 min, pilot in acft + engines off
A5 -> take-off within 1 min, pilot in acft + engines running
A6 -> airborne
State the CIV / MIL priority regulation.
1. Scramble Order (USO) type "Active Air"
2. ARR IFR MIL
3. ARR IFR CIV
4. DEP IFR CIV with CTOT (inform ADDC about slot)
5. Scramble Order type "Exercise"
6. Scramble Order type "Daily Ops"
7. DEP IFR MIL
8. DEP IFR CIV without CTOT
What are the clearance expiry times? Definition of start and end?
airbase - airbase -> 4 min
airbase - ADDC -> 2 min
start when clearance has been issued, ends latest when airborne
How do you clear helicopters for take-off? EC / AS? When do you NOT issue take-off clearance?
Don't issue take-off clearance if
- site uncontrolled, e.g. not on manoeuvring area
- traffic conditions unknown (on manoeuvring area but not in sight)
EC: "T-346, QNH 1018, wind 090 degrees 6 knots, heliport depart at own discretion."
AS: "T-331, taxi approved, QNH 1018, report ready for departure."
AS: "T-331, wind 090 degrees 6 knots, pumaport depart at own discretion."
What has ATC to do in case of a Sierra climb?
- assign transponder code
- find out position if not clear on radar
- give traffic information as far as pracicable
- provide max level to pilot
What are the speed restrictions for MIL traffic?
at and above FL330: > M 0.95
at and above FL100 until below FL330: max. M 0.95
below FL100: M 0.9, liaison flight: M 0.7
inside CTR/TMA: max. 350 kts
State two RT examples for joining instructions.
1. Next reporting point / Kind of approach
2. Runway in use
3. Altitude instruction
4. QNH
"Report circuit positions" -> what will the pilot report?
- mid downwind
- mid baseleg
- begin final
Under what circumstances is formation landing forbidden?
- contaminated runway
- at night
- high bird activity reported
- dissimilar aircraft configurations or types
- technical and operational restrictions (SAF manual) dictate single landing
- short field arrested landing needed
How do pilots roll out after a formation landing?
they stay on each others side, until taxi speed, then both join slow lande (= oriented towards taxiways, exit, TARMAC)
How is the PC-21 traffic circuit at the different airfields?
EMM -> 1 NM longer as prop circuit, 3000 ft

What's the separation for landing aircraft?
1000 metres
What's the separation for landing and departing aircraft?
2000 metres
What's the separation between acft on same runway at night?
two aircraft only at the same time
Explain the simulated forced landing procedure for PC-21.
as to pass two positions:
high key = abeam threshold upwind, 3000 ft / AGL
low key = abeam threshold downwind, 2000 ft / AGL
Is landing over cable allowed?
only for F5 and F18 single landings
Explain the procedure "diversion to land" (general points/conditions, airfields, expressions of acft, procedure)
- ordered by ground control, done by airborne assets
- be able to keep visual contact, transmit either by radio or by visual signals
- escort as far as landing
- designated aerodrome needs to be suitable (LSZH, LSGG or DUB, PAY, EMM)
eyeball / safety element (shooter)
1. Guide over active runway, acft shall fly standard cct
2. Eyeball lowers gear
3. Acft lowers gear as well, stay down -> OK, up again -> not suitable to land
4. Perform full circling via UPWIND, interceptors stay in cct until acft has landed
How does a fixed-wing aircraft proceed with a COM failure for landing?
- fly upwind at 1'600 ft / AGL and request landing clearance by rocking wings
- at end of upwind, climb to cct altitude and join downwind via crosswind
- receive light signals in downwind and act accordingly (steady green = cleared to land, steady red = runway unuseable, orbit airfield at 1000 ft/AGL, flashing red = divert to alternate, will be informed)
How does a NORDO approach within formation work?
NORDO acft is wingman, formation straight-in approach, leader reports 3 greens + does go around, wingman lands
RCF in flight - procedure for fixed-wing aircraft? Radar identification procedure?
- squawk 7700
- try to re-establish radio communication and listen to emergency frequencies
- maintain VMC as long as possible (if unable to comply with radar identification procedure)
triangle right (1min, 120°) -> transmitter failure
triangle left ( 1min, 120°) -> transmitter and receiver failure
RCF in flight - procedure for helicopters?
- in VMC and ground in sight, land at next suitable landing site
- avoid any airfield traffic circuit areas or CTRs
- report problems and intentions to ATC by phone
- return acft to home base
