AVIATR

AVIATR is a mnemonic acronym often used in aviation training to help pilots remember the pre-flight checklist items required for navigation equipment before takeoff. While the specific items represented by each letter can vary slightly depending on the aircraft type, training program, or specific procedure being followed, the general meaning is widely understood.

The letters typically stand for:

• A - Airspeed Indicator: Verify the proper functioning and zero reading on the ground.
• V - VOR (VHF Omnidirectional Range): Check the VOR receiver for proper identification and accuracy, often by tuning to a known VOR frequency and ensuring correct radial indication.
• I - Instruments: Ensure all essential flight instruments, such as the altimeter, attitude indicator, heading indicator, and turn coordinator, are functioning correctly and properly calibrated.
• A - Altimeter: Verify the altimeter is set to the current local altimeter setting (pressure) and reads the correct field elevation.
• T - Turn Coordinator: Confirm the turn coordinator indicates correctly during taxi turns, showing the direction of the turn and the rate of turn.
• R - Radios: Test the aircraft radios by tuning to a known frequency (e.g., ATIS or a ground station) and verifying clear reception and transmission.

Using AVIATR as a memory aid ensures pilots systematically check critical navigation and communication equipment, contributing to flight safety by identifying potential issues before becoming airborne. It serves as a crucial part of pre-flight preparation, complementing other checklist items.
