Flight Planning Flashcards
When is an aircraft defined as ‘low flying’?
FW - Below 2000ft AGL/AMSL
RW + Light prop driven a/c - Below 500ft
What is MSD and when can it be broken?
Minimum Separation Distance
- Directed to by ATC
- Departure of arrival at an airfield
- Precautionary or forced landing
- Emergency
What height should you fly over congested areas?
Altitude that is sufficient to permit a safe landing outside the congested area in the event of an engine failure.
Min 2000ft FW
Min 1000ft RW and light prop a/c
What area does the UKLFS cover?
All UK Class G airspace below 2000ft AGL/AMSL
Laterally to UK FIR boundaries
What is the UKLFS divided into?
UK Day Low Flying System (UKDLFS)
UK Night Low Flying System (UKNLFS)
Who regulated low flying activity in the UK?
MAA
What is the UKDLFS divided into?
20 LFAs (Low Flying Areas) and the Thames Valley Avoidance Area (TVAA):
- 6 are DUAs (Dedicated User Areas)
- 3 are TTAs (Tactical Training Areas)
- HRA (Highlands restricted area) is in the same geographical area as LFA14.
Except for DUAs, who governs LFA booking?
MAMC LFC at NATS Swanick
When does the UKNLFS commence and end?
30 mins after sunset, ends 30 mins before sunrise
What must ALL military low flying be conducted IAW?
Military Regulatory Publication (MRP) Regulatory Article (RA) 2330
What should the UKMLFH be used in conjunction with?
UK Mil AIP (details geographical coordinates of UKLFS areas)
SACs (or LFCs)
FLIPs (e.g. CALF, FIH)
How are LFCs and SACs amended and updated?
CALF (Chart Amendment Low Flying)
Issued monthly
Arrow denotes a change since the last CALF
What are the hours of the UKLFS?
24/7
However, normally:
- 0700-2300 Mon to Fri
What are the weather limits to operate in the UKLFS for a FW aircraft at a speed greater than 140kts?
Flight vis 5km
1500m horizontal and 500FT VERTICAL seperation from cloud
What are the weather limits to operate in the UKLFS for a FW aircraft at or below 140kts?
Flight vis 1500m
COCISS
What are the weather limits to operate in the UKLFS for a RW aircraft?
Flight vis 1500m
COCISS
Where can the UKLFS Safety Frequencies be found?
UKLFHB
Should be monitored along with the guard frequency whenever possible
In the UKLFS, what Mode 3/A Code should FW and RW aircraft transmit?
FW = 7001 RW = 7000
When can information on an aircraft’s susceptibility to HIRTAs be found?
RTS (Release to Service)
What HIRTA details are/aren’t included on LFCs?
High, Med and Low susceptibility printed on the LFC
Very low susceptibility and Pulse RF not printed on LFCs, details available in UKMLFH Area Briefs
What is the minimum MSD/MSC (Minimum Separation Considerations) for FW and RW aircraft?
FW - 250ft
RW - 100ft
OR
Separation given by the ADH (Aviation Duty Holder)
What should be done in the case of a vertical abort out of the LFA into CAS?
Squawk 7700
Contact controlling ATC (on guard if necessary)
How is SALT calculated?
Find max height obstacle
+1000ft
Round UP to nearest 100ft
OR
+ 2000ft if flying over mountainous terrain (>3000ft AMSL)
What is the maximum cruise speed in the UKLFS?
450kts
AT or BELOW 150ft AMSL = Briefly 500kts for tactical purposes
ABOVE 150ft = Briefly 550kts for tactical purposes
Use of reheat (except for trg requirements, emergencies or authorised displays) is prohibited.
What avoidance should you give to red diamond marked avoid areas?
2000ft AGL
0.25nm laterally
What avoidance should you give to permanent glider sites and permanent micro-light sites?
Glider site - 2000ft AGL, 2nm radius
Micro-light sight - 2000ft AGL, 1nm radius
What is PINS?
Pipeline Inspection Notification System
Warnings of PINS activity promulgated by H series NOTAM
Where can information on BCAs (Bird Concentration Areas) be found?
