Towered and non-towered airports UAG-10-004

A farmer asks you to map a field 1.5 miles from a small non-towered airport. The field and the airport both lie in Class G airspace. What permission do you need before flying?

Show the answer

The answer is C: None, but you must not interfere with its traffic

Unless the flight is in controlled airspace, no notification or authorization is needed to fly at or near an airport, so a Class G field beside a non-towered airport needs no LAANC approval. No authorization is not the same as no rules: you must still avoid the traffic patterns and approach paths and yield to all aircraft. UNICOM is a nongovernment advisory station and gives no clearances.

Traffic advisory practices UAG-10-020

Your drone is working just past the west end of Runway 26 at a non-towered airport. You hear: 'Queen Air Seven One Five Five Bravo departing Runway Two Six, departing the pattern to the north.' What should you expect?

Show the answer

The answer is A: It will climb out past the west end before turning

Runway 26 is aligned with about 260° magnetic, so an aircraft departing Runway 26 rolls and climbs toward the west and continues straight ahead beyond the departure end, the west end, before turning out of the pattern; that takes it toward your site. Picturing it departing toward 080° confuses the runway's heading with the opposite end, and departing traffic does not turn before passing the runway end.

ATIS UAG-10-024

A towered airport's ATIS gives the wind, temperature, dew point, altimeter setting and runway in use, but says nothing about ceiling or visibility. What does that indicate?

Show the answer

The answer is B: Ceiling at least 5,000 feet and visibility at least 5 miles

The ceiling, sky condition, visibility and obstructions to vision may be left out of ATIS when the ceiling is above 5,000 feet and visibility is more than 5 miles; their absence indicates 5,000 and 5 or better. The 3,000-and-3 pairing is not the ATIS convention, and the omission is a defined convention, not a sign of missing data.

Call signs UAG-10-030

You hear an aircraft identify itself as 'Tango Baron Three One Seven Kilo.' What does the 'Tango' prefix indicate?

Show the answer

The answer is A: An air taxi or commercial operator without an FAA call sign

Air taxi or other commercial operators that don't have FAA-authorized call signs prefix their normal identification with the phonetic word 'Tango.' Student pilots identify themselves by saying 'student pilot,' and medical priority flights use 'MEDEVAC.'

Phraseology UAG-10-045

Why does AC 90-66C advise pilots to avoid the words 'to' and 'for' in CTAF calls whenever possible?

Show the answer

The answer is C: They can be mistaken for runway numbers or altitudes

'To' and 'for' sound like 'two' and 'four,' so they can be confused with runway numbers or altitudes and leave other pilots unsure which runway or procedure is meant. The concern is misunderstanding, not length, and the words are not reserved for ATC.

Traffic patterns UAG-10-048

A single-engine propeller trainer is flying circuits at a non-towered airport that publishes no pattern altitude. About how high above the airport should you expect it on the downwind leg?

Show the answer

The answer is A: About 1,000 feet

Propeller-driven aircraft fly the pattern at 1,000 feet AGL unless the Chart Supplement publishes another altitude. 1,500 feet is the figure for large and turbine-powered aircraft, not for all traffic, and 500 feet is the helicopter pattern.

Wildlife hazards UAG-10-084

Mapping a rural airport for its manager, you spot several deer at the edge of the runway. What does the AIM advise?

Show the answer

The answer is A: Tell the FSS, tower or airport management

If you see deer or other large animals near movement areas, advise the FSS, tower or airport management; collisions between aircraft and animals on runways are increasing. Chasing them with the drone over the runway would create its own hazard and could interfere with airport operations.
