What is the phraseology used to issue the time a pilot can expect to start engines when gate hold procedures are in effect?

• A. Will advise of engine start up at (time)
• B. Start engines at (time)
• C. Expect further clearance (time)
• D. Expect engine start (time)

Answer: (D)

The key idea is how ATC communicates an anticipated time for pilots to start engines during gate holds. The proper phrase is to say “Expect engine start at [time],” which gives pilots a clear, non-binding expectation: be ready to start engines at that time and proceed when cleared. This phrasing avoids making a directive and aligns with how clearance planning and coordination are handled during holds.

Other options aren’t a good fit because they either sound like a firm command (start engines at [time]), suggest a promise to provide future instructions rather than giving a ready-to-use expectation (will advise of engine start up at [time]), or address something unrelated to engine timing (expect further clearance [time]). Using the standard “engine start” phrasing keeps the instruction precise and consistent with ATC communication during gate holds.
