What does the GRABCARDD acronym help you remember?

  1. Emergency procedures for VFR

  2. Required instruments for IFR flight

  3. Maintenance schedules for aircraft

  4. Weather reporting techniques

The correct answer is: Required instruments for IFR flight

The GRABCARDD acronym is a mnemonic device designed to help pilots remember the required instruments and equipment for flying under Instrument Flight Rules (IFR). Each letter in "GRABCARDD" corresponds to specific instruments or equipment that must be present in the aircraft. This includes items such as: - G: Ground speed indicator - R: Rate of turn indicator - A: Altimeter (adjustable) - B: Barometric pressure indicator - C: Clock (with seconds) - A: Attitude indicator - R: Radio (two-way communication) - D: Directional gyro - D: Digital altimeter or an equivalent device By using this acronym, pilots can quickly and effectively recall the essential instruments and equipment required for safe IFR operation, ensuring compliance with aviation regulations and enhancing flight safety. The other options, while relevant to aviation, do not relate specifically to the GRABCARDD acronym and therefore do not serve the same purpose in terms of regulatory compliance and operational readiness for instrument flying.
