When a pilot declares 'minimum fuel,' what obligation does this create for ATC?
Answer: Acknowledge and ensure the aircraft is not subjected to undue delay
A minimum fuel declaration is advisory, informing ATC that any undue delay may cause an emergency; controllers must acknowledge and avoid adding delay.
A pilot declares 'Mayday, Mayday, Mayday — fuel emergency.' How does this differ from a minimum fuel advisory in terms of ATC response?
Answer: A Mayday fuel emergency triggers emergency handling, crash/fire/rescue notification, and priority clearance
A declared fuel emergency (Mayday) requires ATC to provide immediate priority, notify crash/fire/rescue services, and coordinate priority handling with all facilities involved.
What does 'EDTO' (Extended Diversion Time Operations) relate to in IFR flight planning?
Answer: Extended range operations for twin-engine aircraft over remote areas requiring diversion planning
EDTO governs twin-engine aircraft operations on routes where diversion to an alternate may take longer than 60 minutes, requiring specific fuel, equipment, and planning standards.
In IFR flight planning, what is the significance of the MEA (Minimum Enroute Altitude)?
Answer: It guarantees terrain clearance and navigational signal reception along the entire route segment
The MEA assures obstacle clearance (1,000 ft in non-mountainous areas, 2,000 ft mountainous) and acceptable navigational signal coverage along the entire airway segment.
What is an OROCA (Off-Route Obstruction Clearance Altitude) and when might a controller reference it?
Answer: An altitude providing 1,000/2,000 ft obstacle clearance in a grid square but no signal guarantee
OROCA provides 1,000 ft (2,000 ft in mountainous areas) obstacle clearance within the grid square but does not guarantee navigation signal coverage, used for off-airway operations.
When may a controller clear an IFR aircraft below the MEA?
Answer: When radar contact is maintained and the controller applies the MOCA or MVA as appropriate
Controllers may clear aircraft below the MEA down to the MOCA (which ensures obstacle clearance but not signal coverage) when radar contact is maintained and the MVA provides obstacle clearance.
