CAP413 Flashcards
Where can you get in flight information on the status of Danger Areas (DAs)?
From the nominated service units:
1 - Listed in the UK AIP
2 - Detailed on the legend of the appropriate UK 1/2 mil chart
What two forms can a DA service take?
Danger Area Crossing Service (DACS)
or
Danger Area Activity Information Service (DAAIS)
If you receive no reply from the unit nominated for DACS or DAAIS, what should you presume?
That the relevant DA is active, remain outside.
How should you request to cross a danger area?
“Westbury approach, VYT 82, request crossing service for Danger Area 113”
“V82, Westbury approach, Danger Area 113 active, remain outside”
“Danger area active, remaining outside, changing to Wrayton Information 125.750, V82”
“V82”
How is DAAIS pronounced in transmission?
DAY-ES
How would you request information on a Danger Area’s activity?
“Westbury approach, VYT82, request DAAIS (DAY-ES) for Danger Area 113”
“V82, Westbury approach, Danger Area 113 active (times as appropriate), crossing service available from Loudwater Operations 123.7”
“Danger Area 113 active, V82”
Note - A DAAIS DOES NOT CONSITUTE CLEARANCE TO CROSS A DANGER AREA!
Can you cross a danger area if a DAAIS tells you it is not active?
NO
A DAAIS does not constitute permission to cross a DA. You must contact the relevant unit and request a DACS.
When flying an instrument departure, what must you include on initial contact with approach control (/radar) when departing?
Callsign
SID or standard departure route designator (where appropriate)
Current or passing level
Initial climb level (first level at which the aircraft will level off unless otherwise cleared)
E.g.
“Ronaldsway radar, VYT82, SID 08…, passing altitude 2000ft, FL80” (service…?)
If a procedure has a specific airspeed requirement that you cannot meet (e.g. due to requirement to slow to configure, stall risk, etc), how should you request an alternative from ATC?
“Ronaldsway approach, V82, request 140 knots due configuration”
If already passed descent instructions, how would you contact the approach control unit when arriving IFR?
“Ronaldsway Approach, VYT82, descending FL50, information XXX (or request ATIS, weather, etc)”
Arriving IFR flights operating outside controlled airspace are not permitted to enter CAS until cleared to do so. How would you request this on initial contact with approach control?
“Liverpool approach, VYT82”
“VYT82, Liverpool Approach, pass your message”
“VYT82, {position, height}, request SRA (with intentions if training) and ATIS”
When may you request to change to tower on an ILS at a civilian airfield?
At any point during the final approach.
Get sorted, configured, descending glidepath and trimmed, then swap and contact tower.
If you need to “request holding instructions” for a hold given by ATC, how should you expect the instructions to be given?
1 - Fix
2 - Level
3 - Inbound track
4 - R or L turns
5 - Time of leg (given as a DME if the hold is on a VOR/DME)
How would you freecall an agency whilst en-route?
“Brize Approach, AXX, request Traffic Service”
“AXX, Brize Approach, pass your details”
“AXX is Texan, 2 POB; Valley to Yeovilton via xxx, xxx; 15 miles North of Brize, 3000ft on XXXX, VFR, request Traffic Service”

If you are told to ‘contact’ another ATSU, what does this mean for you?
Your details have been passed on, can just make contact without needing to freecall.
